Diameter 89108 and other related knowledge dedicated conveyor idlers

Conveyor idler is an important component of species and large quantities. It accounts for a total cost of 35% of the belt conveyor, bear more than 70% of the resistance, so the quality of the roller is particularly important. Using the Operation 1. Before using the roller should be carefully examined whether the appearance of serious damage bump phenomenon, rotating roller should be flexible rotation, no jamming. 2. The roller mounting distance should be considered the type and characteristics of the conveyor stream volume size set by the scientific calculations, to avoid too sparse or too dense installation. 3. The installation should be adapted roller mill avoid touching each other. 1. Select the welding process welding process the material according to the characteristics of each welding process corresponds to one type of material, without first determining the need for welding consumables welding materials will not be effective. For example, Mig welding is suitable for welding steel and non-ferrous metals for low-Mag welding aluminum welding Tig welding for stainless steel, aluminum, copper, titanium and their alloys (thickness controlled within 0.5 ~ 8mm of). In addition, the electrode material should be considered 2. Protect gas selection choice of protective gas is particularly important for Mag welding, the use of CO2 will affect the kind of reactive gas to the welding depth. For Mig welding, Tig welding and plasma welding, the use of such as argon and xenon inert gas such old can protect stainless steel, nickel alloys, titanium and titanium alloys, zirconium weldment, so that at high temperature from oxidation. Only Ease of materials (such as titanium, tantalum, zirconium and their alloys) high-temperature oxidation of only demanding purity inert shielding gas. Protection of gas flow rate is also an important factor to be considered, it also depends on the size and capacity of the protection device. At the same time it should be taken to avoid mixing inert gas does not contain or produce a venturi effect with the surrounding gas. Laser welding generally require an inert shielding gas, usually helium, but also often contain added some of argon, a mixed gas, so that we can for certain metal welding needs. 3. The welding work, there are many factors that affect safety, (such as welding spatter, burn, explode, spark, current, radiation, light burning, smoke ......) so the device placed around a protection facilities (such as shields, Ventilation air chambers, etc.), such as the unconditional use of protective facilities, can be personal protective equipment (such as protective clothing, welding gloves, safety shoes, goggles, etc.). In confined spaces also equipped with gas detectors to prevent hypoxia (oxygen content <17%). 4. Prepare pretreatment before welding is very important for the welding, welding by this surface treatment step makes it easy to weld. Many industries require leveling, correct pretreatment processes. Not only that, but also through rust protection and other processes to improve the quality of welding products. 5. docking accurate positioning precision docking plate is precisely the premise of the anchor. Welding high precision positioning requirements, the welding process should always control the position of the weldment. 6. External environment control control air inlet, to prevent liquids or other particles affect the welding is very important. When welding, to the installation of wind facilities (to prevent external air intake in the welding). 7. welding speed monitoring to ensure the stability of the welding speed CNC equipment must be used. To ensure the quality of the weld electrode must control the speed of uniform and stable. If the welding speed is too fast, easily lead to Weld and had to rework. 8. The electrode characteristics of different welding processes, suitable electrode angle is different, so the operation should confirm whether the appropriate angle. Weld quality depends largely on the type of current and polarity. One big advantage is its Tig welding seam is flat and penetration rate. Another important part of maintenance welding work 9. The device is maintenance of equipment, including regular replacement of aging parts, remove scaling and other work on the inner wall of the nozzle. 10. Select the welding process to choose the most suitable welding process to get the best welding effect depending on the thickness of the weldment. Undoubtedly laser welding and Mig welding is the best welding two welding process. Look after welding torch to maintain the proper angle of inclination, otherwise it will lead to an inert gas escapes, sticky pad surface damage and other consequences.
