Hibernia supply of high quality gas springs factory direct price advantages

Gas spring gas spring (gas spring) is a way to play a supportive, buffer, brakes, height adjustment and angle adjustment and other functions of industrial parts. It consists of the following components: cylinder, piston rod, piston, seal guide sleeve, the filler (inert gas or gas mixture), and a cylinder outer cylinder control element control element (means controllable gas spring) and joints. Basic information Chinese name English Name gas spring gas spring strut alias, air support, the nature of industrial parts recliner composition pressure cylinder piston rod, piston filler inert gas or gas mixture gas spring principle is sealed pressure cylinder filled inert gas or gas mixture, the pressure chamber is higher than atmospheric pressure several times or several times, the use of the piston rod cross-sectional area smaller than the cross sectional area of ??the pressure differential resulting in movement of the piston rod is achieved. Since the fundamental principle on a different gas spring than normal spring has very significant advantages: speed is relatively slow, little change in the dynamic force (generally 1: 1.2 or less), easy to control; drawback is the relative volume of the coil spring no small cost high, life is relatively short. The difference is that with the mechanical spring, gas spring with near linear elastic curve. Standard gas springs elastic coefficient X between 1.2 and 1.4, other parameters can be flexibly defined according to requirements and conditions. Depending on their characteristics and applications, also called support bar gas spring, gas strut, adjuster, pressure bar, damper and so on. The gas spring as the structure and function classification, gas springs freestyle gas spring, self-locking gas springs, traction gas springs, free to stop gas springs, swivel chair gas springs, gas spring, damper and other types. The products in the automotive, aerospace, medical equipment, furniture, machinery manufacturing and other fields have a wide application. 2 spring First, the free type gas spring (supporting bar) (Lift gas spring) is the most widely used gas springs. It is mainly play a supportive role, only the shortest, longest two locations, are themselves unable to stop during the journey. In the automotive, textile machinery, printing equipment, office equipment, construction machinery and other industries most widely used. Free gas spring, with its light, smooth, easy to operate, price, etc., in the automotive, engineering machinery, printing machinery, textile machinery and other industries until the GF applications. Or alpine environment, acidic or alkaline environment. Second, the self-locking gas spring (adjuster, controllable gas spring) (Lockable gas spring) on ??the medical device applications most. The use of some kind of gas spring release mechanism can travel anywhere in the stop, and later stopped a great locking force (up to 10000N and above). Third, free to stop gas spring (friction gas springs, gas spring balance) is mainly used in the field of kitchen furniture, medical equipment. It features between free gas springs and self-locking gas spring: do not need any external structure can be stopped at any position in the stroke, but no additional locking force. The main effect is to achieve through the controller (handle or cable). It may also be achieved by stretching rod. When using the controller to adjust in an ideal position to stop, the valve will be closed independent of the piston rod is locked in the desired position. When locking occurs, can achieve lock. However, if more than the locking force the locking function will no longer be valid. Fourth, swivel chair gas spring (pneumatic rod) is mainly used in the chair, adjust the position of role play. Its characteristics are controlled, relatively large demand. Fifth, traction gas spring (pull strength springs) (Gas traction springs) is a special kind of gas spring: other gas springs when the free state are in the longest position, that is, after receiving an external force from the longest The position to minimum position, and the free state traction gas springs in the shortest position, the shortest run by traction at the most advantages. Traction gas spring is also a corresponding free type, self-locking type. Sixth, the damper (Damper) are used more than in the automotive and medical equipment, which is characterized by resistance to change with the speed of operation. Can be clearly linked to the speed of institutions have a dampening effect. Dampers are mainly used as a buffer role, its greatest feature is the air force of the spring with the change velocity and change. When faster boot time spring gas spring force of the point movement of resistance to significantly increase, and when the point of the movement is very slow, almost no resistance. Dampers are used in washing machines, refrigerators and other industries. In addition, the material points and ordinary stainless steel gas springs and gas springs. The largest amount of ordinary steel gas spring, stainless steel gas springs are used for more demanding environmental requirements places, such as food machinery, medical equipment, military industry, high-temperature characteristics and applications. Gas spring is a spring characteristic can be labor-saving lift spring, can be divided into self-locking gas spring (such as lifting the seat bottom, seat back after the boss, etc.), can not be self-locking gas spring (such as car trunk, closet doors The riser support), the gas spring structure is dominated by the sleeve, piston and piston rod, etc., to join the high-pressure air or high-pressure nitrogen gas in the sleeve, both ends of the piston area ranging from creating a pressure differential, as well as to push the piston and piston rod support person or a heavy object. Judge the quality of judging the quality of the merits of a gas spring mainly from the following aspects: first, it is still intact, if the seal is not good oil spills, leaks and other phenomena occur during use; followed by accuracy, such as the need 500N gas spring, some manufacturers out of the force of error does not exceed 2N, some manufacturers of products and 500N actual needs may differ distant; again is life, its life with its fully retractable number of calculations; and finally is the force value changes in itinerary, the ideal state of the gas spring should value remains the same throughout the stroke force. However, due to the design and processing factors, making air travel in the spring force value inevitably change. The magnitude of the change is an important measure of a good quality gas spring ring, the smaller the magnitude of change, indicating that the better the quality gas springs, otherwise the worse! Calculation principle is the use of gas springs Calculation using leverage theory and linear inverse proportion Theorem coating technology combined with gas spring presentation from the current market, most manufacturers still use more traditional painting, as we all know, paint advantage is low cost, and the operation is relatively simple, usually one or two a plant chef to get it, but the painting process also has shortcomings such as: relatively unpleasant odor and corrosion resistance are not prominent, but also for environmental protection this fast is a let each Manufacturers troublesome thing. So how in the end the painting process how to do it? Generally the following steps: degreasing - washing - Remove the bottom of the scale (or do first this step) - Table tune - phosphide - washing - drying - painting - drying (drying temperature depending on the kind of paint manufacturers use) over here, by the way we can in this process phosphate, then mostly zinc phosphate manufacturers now use, the process is also low cost, easy to operate, general gas spring manufacturer Directly for the slot to be all right, basically do nothing to add. Phosphate It also has some shortcomings, such as: in use would produce a certain phosphate slag, phosphate coating affect the gas spring itself to do, and when the slag content of the phosphating solution gradually increased, easily absorbed in the car body, easy slag caused these early blistering and shedding coat, and reducing vehicle coating adhesion and corrosion resistance. \ "; The phosphate residue is brought into the electrophoresis tank can contaminate electrophoresis bath, resulting in the ultrafiltration membrane clogging and reduce the life of ultrafiltration membrane \."; Blocking nozzle and the circulation pipe, causing unnecessary turn slot. \ "; Easily blocked heat, too much nitric acid cleaning will not only shorten the life of the heat exchanger, and nitric acid from leaking into the phosphate solution will be hazardous casual human requirements for environmental protection and high-quality products, also in. This is a gas spring surface coating and some newer coating process to meet the needs of the market. Since swimming paint (autophoresis coatings) whose official name is automatically deposited coatings, also known as chemical coating or acidic coating. advantage of this method is used for coating and film-forming method economic, painting equipment is simple, low energy consumption, easy operation, low cost of painting and rust-proof and strong; almost completely without organic solvents, less polluting and environmentally friendly paint from autophoresis Since the 1970s, is mainly used for industrial metal surface (such as cars and other metal parts) of the coating. there will be a lot of problems when the gas spring gas spring mounting installation techniques, such as you, www.tzjpqth.com pocket in the same core coil spring so you can ensure the integrity of the bottom, the depth of the pocket should have a limit, keeping the angle between 30 degrees, about 2-3 mm in length control, wherein the pressure pad full access to the gas spring, must be mounted Consider the style of the entire thread, if the pocket is too shallow, and his core might be deeper. Before installation can be considered the first test, see if you can meet the needs of the space must be installed when you install the gas spring piston rod down position, may not flip. This can reduce friction and ensure the best quality and buffer damping performance. fulcrum is good or bad will directly determine the installed gas spring can work properly when the fulcrum is closed, let move to near the center line, so that automatic door open. gas springs work force should not be the role of tilt or lateral force can not be used as a handrail. long this time will lead to changes in the structure of the gas spring. Gas spring to ensure the reliability of sealing can not be damage piston rod surface, the paint is strictly prohibited chemical substances applied to the piston rod, and should not be pre-installed on the gas spring desired position after processing such as welding, grinding, spray paint, etc., it will affect the life of the gas spring In the course of work must ensure that the equipment look neat and clean. gas spring at work internally to produce a component inside the warehouse, which ensures the best damping effect and cushioning function of gas springs gas springs working structure principle works is an inert gas as an elastic medium, be sealed and lubricated with oil and the delivery pressure of the elastic element called a gas spring. It is actually a sleeve-type air springs a variant, but also to further improve air spring sleeve elastic properties and development. Therefore, he also has the general characteristics of the air spring structure. gas springs generally composed of cylinder, piston seals and external connections consisting of high-pressure nitrogen gas or an inert gas and oil in the cylinder forming the circuit. piston damping so that rod chamber and the rod chamber interlinked, so that the two chambers pressure equal use of the two chambers produce compressible elastic force difference and gas area gas spring with a compact structure, large work schedule;.. smooth movement, can play damping cushioning; nearly unchanged with a stable characteristic line; simple, safe and reliable. But higher processing costs. Force air spring sleeve according to the principle, in any known gas spring stroke s, is: F = initial pressure pVA / v-As cylinder; initial volume within the cylinder; piston rod cross-sectional area, due to use of gas springs different, and have different structures and types. China's current production of gas springs have not locking gas springs and locking gas spring types. Not locking gas spring works can not be locked gas spring depending on the use of two compression and tension spring air. Compressed gas spring principle compressed gas spring is widely used in automobiles, construction equipment, medical equipment and other occasions, mainly play a supportive role. This spring structure is simple, when in use, the piston rod down. When the piston rod is pressed into the cylinder, the cylinder has a cylinder portion of the oil flow automatically into the cavity of the rod. Due to the pressure difference at both ends of the cylinder surface of the piston, forcing the piston rod. Near the end, the cavity fluid dampening effect. Property from the extension and compression ring formed by the process curve can be seen throughout the trip into hydraulic damping two AM and aerodynamic damping MD. Tension gas spring gas spring tension principle is mainly used for doors and windows open and close, fitness reset devices. Its principle and the same compressed gas spring. Lockable gas spring works locking gas springs can be divided according to usage reconcile lifting angle lockable gas spring, according to their performance can be divided into rigid and elastic lockable gas spring, according to their structural characteristics can be divided into single cylinder and double Lockable gas spring cylinder. Angle adjusting lockable gas spring principle angle adjusting lockable gas spring angle adjustment locking gas spring angle adjustment locking gas spring is a stepless adjustment element wide range of applications. Mainly used for adjustable seats, medical beds, plotters and office equipment and the like. Angle adjustment lockable spring is monocular structure. Floating piston mounted genus rigid locking rod cavity adding some oil. Do not install floating piston genus resilient locking, without refueling fluid in the rod chamber. Angle adjusting lockable gas spring gas, oil passes through the stop valve rod chamber and the rod chamber communication. When the shutter button is pressed small, cut-off valve is open. Piston rod out; when the button is released, the valve is closed, the spring will be locked ring characteristic lines which are formed in the course of their work, similar to the non-locking compression gas springs. However, in order to lift the locking gas spring opening force Fk state form an additional ring of characteristic lines. Lifting lockable gas spring locking gas spring lift principle is mainly used for rotating chair height adjustment. This spring is generally binoculars structure and the elastic lock. Movement and angle adjustment similar lockable gas spring. Seat by operating the adjusting lever Lift slowly to achieve the best position the gas spring non radial force to prevent product damage curved high-pressure gas sealed gas spring, so the installation of non-roasted and percussion, no case under the guidance of professionals, is prohibited secretly dismantling, to prevent accidents. Gas springs belong sliding seal, so the installation or use of the rod surface, is strictly prohibited bump, attached to paint, glue and other substances otherwise it will affect the life of their products. Gas spring environment: temperature -40 ℃ to + 80 ℃, should not be used in a vacuum environment, not suitable for use in corrosive environments. Controllable gas springs must be completely open the valve before proceeding to apply force to control the lift height, which will cause the rod bent, product damage. The use of gas spring: a spring made of the compressibility of air in a closed container. Its relational features jojoba deformation and load line curve can be designed plan as needed. Air springs can be maintained at any load constant natural frequency, can withstand the radial and axial loads, but also to pass a certain torque, by adjusting the internal pressure to obtain different carrying capacity. Many forms of air spring structure with bladder and diaphragm, commonly used in anti-vibration system of the vehicle suspension and mechanical equipment. Variable damping gas spring is a special kind of compressed gas spring, the principle of continuous change damping groove sections to reduce the gas spring stretching speed with deceleration smooth, non-impact, etc., connected to the body smooth continuous play buffer and support role. In the car (especially car), home appliances, medical equipment and other applications more. Lockable gas spring is a way to travel anywhere in locking gas springs. Lockable gas spring piston rod end, a jack, push the ram, the internal valve open so that the flow of gas or oil, the lockable gas springs can be as free as compressed gas spring stretch; when you reach the desired position release mandrel inside the valve is closed, the piston rod can be locked. Lockable gas spring locked with its locking force can carry a greater load, if the load on more than locking force is locking function fails. Lockable gas springs also have the support, adjust the height or angle of capabilities that enable anywhere to stay, easy to operate, the lock can be accomplished by adjusting the handles, etc. in any position, smooth operation, comfortable to use. On cars, trains, aircraft seats, medical equipment, massage chairs, SPA chair, leisure sofa and other equipment widely used. Compressed gas spring is a way to play a supportive, buffering industrial parts. It consists of the following components: a pressure tube, rod, piston, seal guide sleeve, the filler (inert gas or gas mixture), other components and joints. The principle is the sealed pressure cylinder filled with inert gas or gas mixture, so that the cavity is at high pressure, the use of differential cross section of the piston produces a pressure differential across the piston rod is free to achieve stretching. Gas Spring contrast to the common mechanical springs have a very significant advantages: speed is relatively slow, little change in the dynamic force (elasticity coefficient X is generally between 1.2 and 1.4), easy to control. Gas springs with near linear elasticity curve, so exercise more ease and comfortable. Other features: The main play a supportive role, only compression, stretching two positions, unable to stop on their own during the journey. Easy to install, safe, low-noise, energy-saving and environmental protection. Full buffering, stable and smooth stroke. Widely used in automobiles, aircraft, office furniture, construction machinery and other industries. Pneumatic and hydraulic strut supporting bar 1 any different, they are not the same medium, compressed air, a hydraulic oil. 2, their carrying capacity is different, because pneumatic generally less 1MPa hydraulic generally 30MPa (domestic) or less, higher than the value of the element and the ultra-high pressure pump too high. Because the pressure (Tong said pressure we mean pressure, are to say how much and how many kilograms MPa) high, the driving force also big. 3, the hydraulic oil is recycled, the pneumatic is no longer recovered spent gas. 4, pneumatic components prettier than hydraulic components. 5, in the factory for general use centralized gas supply pneumatic, hydraulic generally is a machine a hydraulic station. 6, the hydraulic control than pneumatic control running accuracy, (because the gas compressibility large) Advantages: 1, the ratio of the carrying capacity of the hydraulic pneumatic carrying capacity (at the same bore) 2, the hydraulic control circuit complex than pneumatic ( Because the hydraulic oil must be returned) 3, pneumatic hydraulic maintenance to more than convenient. (A problem, disconnect the pneumatic tube can spit at it, there is no air out for exclusion, hydraulic generally can not do this. Danger!) 4, pneumatic hydraulic connections to more than easy, pneumatic generally quick connector coupling. 5, pneumatic components hydraulic bigger than small. 6, Dodo precision hydraulic bearer than the oil pressure is high (because the gas compressibility large) 7, pneumatic generally centralized gas supply, easier to manage than the hydraulic pressure. 8, the hydraulic control want to change the hydraulic oil, pneumatic not, so post-use costs than pneumatic. 9, I think it pretty pneumatic components, (pneumatic components most aluminum or copper material, and hydraulic general use cast iron) 10, in the company will generally be oil spills, headache, leakage will be a little less, and spill the ugly pedestrian Unsafe National standard gas springs spring China began in the early 1960s standardization, has 40 years of history, has formed a relatively complete system of standards, there are 22 national standards for the spring, the industry standard 30. 1999 by the State Administration of Quality Supervision approved the establishment of the National Standardization Technical Committee of the spring (SAC / TC235), spring to comprehensively promote the standardization work. Founded in 2004 on the international ISO / TC 227 (spring), in order to participate as a member of the work, which marks the Chinese spring standardization work has entered a new phase, that is; comprehensive tracking, substantive participation stage.
