Overheat analysis of gear oil pump motor

July 03, 2019

Gear oil pump is mainly used in oil, chemical, metallurgy, mining, power station and other industries, such as oil medium transfer, supercharged, fuel injection, etc., as well as thin oil circulation in large machinery and equipment. Lubrication pumps can be used in all kinds of machinery and equipment. use.

Motor overheating is a common problem in the working process of gear oil pumps. The specific analysis and detection are as follows:

1. Does the scope of use (flow, head) exceed the design requirements of the gear pump?

Select the right motor according to the series
2. Does the specific gravity of the medium exceed the gear pump configuration motor?

Configure the appropriate motor for Oe gear oil pump
3. Is the packing gland pressure too tight or the mechanical seal spring too tight?

Re-adjust the amount of spring compression of the gland or mechanical seal

4, pump assembly quality is poor, there is friction or motor and pump shaft is not the same?

Check assembly quality and troubleshoot assembly?

According to the above conditions, we can analyze one by one to find out the real cause of motor overheating, and repair it according to the corresponding fault.
