Roots blower, as a rotary machine, has relatively stable working characteristics. With simple structure and convenient manufacturing, it is suitable for gas transmission and pressurization in low pressure occasions, and can also be used as a vacuum pump. Recently, some customers reported that there was oil leakage of Roots blower in use. This may be caused by overfilling or seal wear.
The reason for the conflict between impellers: there are impurities on the impellers, so the gap between impellers is too small; Bearing wear leads to increased clearance. Treatment method: remove the dirt and check whether the internals are damaged; Adjust the clearance between gears. The reason for the high temperature of Roots blower: there is too much oil in the oil tank of Roots blower, and its filter is blocked; Excessive wear of impeller; The ventilation is not good, and the indoor temperature is too high, resulting in high inlet temperature; Treatment method: lower the oil level or carry oil.
Remove the blockage; Decrease the pressure difference passing through Roots blower; Correction gap; Open vents to lower the room temperature; Increase the rotating speed to avoid belt slipping. The reasons for the lack of Roots blower flow are: the inlet filtration of Roots blower is blocked; Treatment method: remove the dust and blockage of the filter; Tension the belt and add the number; Adjust the inlet pressure to reach the regular value; Review and correct the pipe.
The reason why the oil of Roots blower leaked into the casing is that the oil tank of Roots blower is too high and leaks out from its oil outlet; Its seal is damaged, resulting in oil leakage at the shaft end; The pressure is higher than the regular value. Treatment method: reduce the oil level; Replace the seal; Dredge its vents. The reason why the motor of Roots blower is excessively cut: compared with the regular pressure, the pressure difference is too large.
1. Roots blower contains dirt
Roots drum If there are many impurities on the fan impeller, the gap between roots fans is too small, which will affect the normal operation of the fan. The exhaust of the fan is not smooth, roots drum Excessive fan vibration will affect the compactness of the overall structure of Roots blower, which may cause oil leakage of Roots blower in the long run.
2. Too much lubricating oil is artificially injected
When we inject lubricating oil, we must inject according to the standard to avoid injecting too much lubricating oil.
3. The end cover of oil tank is unqualified in processing
The quality problem of the oil tank causes cracks in the oil tank, or some external force causes limited damage, which will also lead to oil leakage of Roots blower.
4. Excessive bearing wear
The bearing is excessively worn, resulting in increased play and oil leakage.
There are other reasons for the oil leakage of Roots blower, most of which are: Roots drum Fan product quality problems and unscientific operation. At present, Huadong blowers have been technically improved to achieve zero leakage. Huadong Roots blowers have all gone through CAD drawing, precision machining by CNC machine tools, and multiple detection processes to ensure zero leakage of lubricating oil of Roots blowers.
I believe that after reading the above, you should also pay attention to Roots drum The key factors of fan oil leakage have been understood, and I hope it will be helpful to everyone.
