The stainless steel high temperature resistant fan is only a kind of gas conveying equipment, and its composition and structure are not complicated. Stainless steel high temperature resistant fan installation preparation The main components of stainless steel high temperature resistant fan are: impeller, volute, air inlet, bracket, motor, pulley, coupling, muffler, transmission parts (bearing), etc. After the stainless steel fan is used for a long time, some parts will have problems under the influence of external factors or material factors. Today, the editor will introduce which parts often have problems?
When designing stainless steel high temperature resistant fan gears, a certain amount of tooth wear must be calculated. During normal use, its wear is negligible. If the oil level in the gearbox is high, too much oil will be heated during the mixing process, and the temperature at the bottom of the oil tank will be too high. In this case, if you continue to operate, the gear will heat up and may be affected by rapid wear, resulting in impeller blade contact or unit jamming.
The service life of the supercharger is closely related to the bearing. Gradually wear may change the position of the shaft until the impeller rubs against the cylinder block or top plate. Sudden bearing failure usually has serious consequences. Since the impeller shaft assembly is no longer supported and correctly positioned, the housing and gears may be severely damaged immediately after a bearing failure.
Three, transmission shaft sealing components
The assembly consists of two independent lip seals immersed in oil, which are located in the drive end cover. If the oil level of the oil level gauge rises, it means that there is too much oil leaking through the internal components and should be replaced as an assembly. Unless the seal or its supporting surface is damaged, there is little chance of leakage through external components. In addition, the smoothness of the shaft has a considerable influence on the performance of this seal. Operational problems may be caused by reasons other than damaged parts. Since the gap is only a few thousandths of an inch, changes in installation or pipe supports may cause interference and friction.
Foreign matter entering the stainless steel fan housing can also cause some trouble. If you encounter this kind of problem, but find the inside of the casing is clean, please disconnect the pipe and loosen the mounting bolts, re-level and align the driver. After tightening and installing, make sure that all pipes are properly connected to the equipment before reconnecting.
The above is an introduction to the problems of stainless steel high temperature resistant fan parts. In actual use, it must be checked and maintained regularly.
