Analysis of overheating of gear pump motor

Gear pump is mainly used in oil, chemical, metallurgy, mining, power plants and other industries of oil media transfer, pressurization, fuel injection, and large oil and thin oil machinery and equipment circulation, in all types of machinery and equipment can do lubrication pump use.
Motor overheating gear pump is often in the course of the work of the problem, the specific analysis and testing are as follows:
1, the use of (flow, head) than the gear pump design requirements?
Select the appropriate type of motor spectrum

2, the proportion of more than gear pump gear motor configuration?
Equipped with the appropriate motor gear Dajiang gear

3, packing gland pressure is too tight or mechanical seal spring is too tight?
Readjust the amount of spring compression of the gland or mechanical seal

4, the pump assembly quality is poor, there is friction or motor and pump shaft is not the same?
Check the assembly quality, eliminate assembly problems?
For the above conditions, one by one to do the analysis to find out the real cause of motor overheating, in accordance with the corresponding fault, maintenance treatment.
