The causes of the piston pump overheating are analyzed

Causes the piston pump to overheat the reason is more complex, and the heating part is not single, which includes the liquid, mechanical and other aspects. The causes of overheating in each part are various. The following is a description of the causes of overheating in liquid and mechanical aspects. There are two causes of excessive heat of plunger pump, as follows:

 

First, mechanical conflict generates heat

 

Because the appearance of movement is in the state of dry conflict or semi-dry conflict, the moving parts conflict with each other and generate heat;

 

Second, the liquid conflict generates heat

 

The high pressure oil passes through various gaps and leaks into the low pressure cavity.

 

So accurately selecting the space between the moving parts, the fuel tank volume and the cooler can eliminate the appearance of excessive heat and oil temperature of the pump. In addition, blockage of oil return filter results in high oil return back pressure, which also causes high oil temperature and overheating of pump body.

 

Small make up want to remind everybody here, cause the reason that causes piston pump overheat, besides above two respects the working environment of piston pump also should notice, the stand or fall that heat dissipation condition.
