Roots blower clover Roots blower function, low noise, high efficiency, easy to operate, maintenance-free. Overall performance is better than two leaf blower, manufacture of high precision, high efficiency leading domestic level; is the most efficient, the most widely Roots blower, throughout the petrochemical, building materials, electricity, metallurgy, fertilizer, mining, ports, textile, food, paper, aquaculture and wastewater treatment, environmental protection industry and many other areas, mostly for conveying air, can also be used to transport the sealed gas, hydrogen, acetylene, carbon dioxide and other flammable, explosive and corrosive gases. Roots blower (ordinary) blower widely used in ceramics, building materials, paper, metallurgy, electricity, petroleum, chemical, textile, aquaculture, waste water treatment, food and other industries pneumatic conveying system for conveying air as well as the kinds of neutral gas. But not for the transportation of flammable, explosive, toxic and corrosive gases. Processing of high precision, good performance, reliable operation, long life, simple structure, maintenance, and easy maintenance. Including attachments, fans standardization body, improve the production system, at any time to meet your requirements. 80kPa booster fan running within range, without cooling water. A basic introduction to the Roots blower, English Roots blower, rotary blowers are the property of volume, the use of the two-lobed rotor relative motion within the cylinder to compress and transport gas rotary compressor. This blower is simple structure, easy to manufacture, for low pressure gas delivery and pressurized situations, also be used as a vacuum pump. Two basic principles are the property of volume rotary blower blowers. This compressor rotor shaft by synchronizing gear so that the two rotors remain engaged. The rotor and the cylinder inner wall surface of each concave portion of the composition of the working volume, during the rotation of the rotor away from the gas intake port, when moved to the vicinity of the exhaust port and an exhaust port communicating transient, due to the higher pressure gas reflux, then the pressure in the working volume of a sudden increase, and then the gas is supplied to the exhaust passage. Two rotors do not contact each other, the gap between them tightly controlled by a seal, so the gas discharged from the lubricating oil contamination. [1] The three main features of its biggest feature is the use when the pressure to be adjusted within the range of variation allows the flow of very small and select a wide range of pressures, has forced gas transmission characteristics. When the transmission medium is not oil. Simple structure, easy maintenance, long life, low vibration machine. Four major media blower transport medium for clean air, clean gas, sulfur dioxide and other inert gases, specialty gases industry (coal, natural gas, methane, carbon dioxide, sulfur dioxide, etc.) and the product of choice for high-pressure conditions. In view of the above characteristics, which can accommodate a wide range of metallurgical, chemical, fertilizer, petrochemical, equipment, building materials industry. 5 structure according to the shape of the rotor, blower and clover leaf type is divided into two types. Clover rotor rotates once every three times by two rotor suction and discharge. Compared with the two leaf type, gas pulsation is small, too small vibration, low noise. 6 parameters Roots blower speed is 150 to 3000 rev / min. Flow from 0.15 to 1200 m3 / min, pressure of 9.8 to 196 kPa, 0.75 to 1000 kilowatts of power, single weight of 100 to 9000 kg. 9 The main purpose of sewage treatment, aquaculture, pneumatic conveying, cement, chemical, foundry, flour and other economic sectors. About 10 maintenance requirements Roots blower is fed into the gas medium temperature not higher than 40 ℃, impurity content of the medium particles no larger than 1000mg / m3, the maximum size of the particles should be 0,1mm below. When you use a boost, boost the value shall not exceed the rated nameplate on the blower provisions, due to the special structure of the Roots blower, so the operation requires many differences with other fans, must pay attention to. Start blower should be ready before starting the boot following the preparatory work; ⑴ fully open the intake valve, the outlet valve and the bypass tube; ⑵ check whether the flow inlet air filter, the filter is fully imported Open; ⑶ inspection of pipes, valves, muffler, air filter support is solid, not a load force applied to the chassis; ⑷ Check the oil is good, the model is appropriate, should reach the required depth of the lubricant layer of oil above the 3 ~ 5 cm, the cooling water system is smooth; ⑸ toggle couplings, check whether the impeller transit spiritual fitness, with or without friction collision; ⑹ check all parts connection is good, loose; ⑺ cleared debris around, keep the fan two meters not within the scope of the debris; ⑻ check the electrical part and down the boot device is intact; ⑼ overhaul inspection tool is available, fire fighting equipment adequacy complete. After more work done, to boot. Roots blower boot should first empty running 20 to 30 minutes, observe all blowers have a normal phenomenon, if there is an impact or friction sound, you should immediately stop checks, and troubleshooting. After the empty machine is working properly, you can load the boot. After the normal operation of the fan, gradually adjusting the outlet valve (or gradually close the vent valve), and gradually loaded to the rated pressure, but not overloaded operation. When the boot is absolutely prohibited, the outlet valve fully closed, can not suddenly stop when full. When the blower running normal operation, the operator should pay close attention to the health of all components, always observe the vibrational temperature of the components of the machine, the machine, if an exception should be shut down immediately. Stop normal shutdown blower is to first open the bypass pipe, a "leaked" After the wind drop down (almost zero), in order to cut off the power, and then close the intake valve, cooling water system. Abnormal shutdown should be considered first open the bypass pipe, a "leaked" 11 Operating Instructions edit ⒈ transport medium inlet temperature is usually not more than 40 ℃. ⒉ medium particle content shall not exceed 100mg / m3, the maximum particle size must not exceed half of the minimum operating clearance. ⒊ operation bearing temperature not higher than 95 ℃, the oil temperature is not higher than 65 ℃. ⒋ use the boost pressure shall not exceed the range specified on the nameplate. ⒌ blower impeller and casing, impeller and the side panels, the impeller and the impeller clearance factory adjusted, to ensure that the gap when reassembled. ⒍ blower running, the main fuel tank, fuel tank oil level in the oil level gauge must be between two red lines. 12 edit a basic requirement, the blower shall comply with the provisions of this standard, and in accordance with prescribed procedures approved manufacturing drawings and technical documents. [2] 2, the blower design, manufacturing and general technical performance should be consistent with JB / T, the provisions of 8941.1. [2] 3, the blower intake air temperature should be no higher than 40 ℃, the gas content of the solid particles is not greater than 100mg / `m ^ 3`, the largest particle size not greater than the minimum working space within each cylinder blower components of relative motion half normal use conditions. [2] 4, under specified operating conditions, blower cumulative uptime should be no less than 6000h. [2]
