Several reasons for wear and tear on Roots fan parts
Roots FansIn the process of using the parts appeared to wear serious situation, then what is the reason for this situation? Roots fan small editor to take you to understand.
1, the initial wear stage of the initial wear stage for the material wear stage, at this time between the blower parts on the surface of the unevenness of the place as well as the oxidation layer, decarburization layer, due to the operation of the Roots fan parts, the role of mutual friction is quickly smoothed. Roots fan due to the impeller in the body running without friction, do not need lubrication, so that the discharged gas does not contain oil. It is the ideal pneumatic conveying gas source for chemical, food and other industries. At this time, the equipment can show high productivity, although this is a short period of time.
2, normal wear and tear stage of this stage for the material wear and tear of the second stage, the general wear and tear of Roots fan parts with time uniformly increased and slower. Equipment can have high productivity and processing quality, this stage is longer.
3, sharp wear stage this stage for the material wear three stages, this time the normal wear and tear relationship has been destroyed, making the wear and tear increased dramatically, after leading to stainless steel blower parts damage, equipment stop. Roots fan is a volumetric operation type blower. When used, with the pressure change, the flow rate change is very small. But the flow rate changes with the rotational speed. Therefore, the pressure selection range is very wide, the flow rate can be selected by selecting the rotational speed to achieve the need. Roots fan blowers do not require lubrication due to the frictionless operation of the impeller in the body, making the discharged gas oil-free. It is an ideal air source for pneumatic conveying in chemical, food and other industries. And before that, the precision, performance and productivity of the equipment are greatly reduced. Therefore, the general is not allowed to use the Roots fan parts to the stage of intense wear, in the Roots fan parts tend to normal wear and tear stage late when it should be repaired or replaced, this stage is also shorter.
