How to solve the three common faults of Roots pumps

Any device will have some common malfunctions, even Roots pumps are no exception. So understanding its common faults and solutions can help you operate the equipment well and also solve problems when the equipment malfunctions. So below, the editor will talk about its three common faults and corresponding solutions

1. The Roots pump is very hot, which is due to our selection of a front stage pump with poor pumping speed, resulting in excessive compression ratio, high pressure, poor cooling, smooth gearbox oil, contact between the rotor and pump casing, and poor smoothness of gears, bearings, and oil seals.

Solution: Select the front stage pump from scratch, adjust, control pressure, cool, adjust oil volume, trim, ensure appropriate oil volume, and achieve outstanding smoothness

2. Unstable operation, excessive noise, low efficiency, and other issues during the operation of Roots pumps are actually related to our own maintenance. Unstable operation is caused by factors such as voltage and improper assembly

Solution: Excessive noise is caused by the device being unstable or not smooth enough, so it's worth trying to smooth the machine

3. Sometimes the pipeline of the Roots pump cannot function properly due to conductivity, resulting in a decrease in the pumping speed of the front stage pump and air leakage at the relief valve, leading to a lack of pumping speed, etc

Solution: Increase the conductivity of the pipeline, repair or replace the previous stage pump, and tidy up the overflow valve

In fact, many common faults of Roots pumps are caused by not carefully checking the equipment before starting, not operating correctly during operation, and not doing a good job in maintenance and repair in the later stage. Therefore, to reduce the failure rate of the equipment, it is necessary to strictly follow the correct operating steps to inspect, start, use the equipment, and so on, in order to truly reduce the occurrence rate of equipment failure
