What are the causes of overheating and oil leakage of hydraulic brick machine plunger pump?
2021-11-15
Hydraulic brick machine hydraulic system with the pump is mostly plunger pump, it is to provide power components, in normal working condition, the plunger pump work without noise not heat, so as to ensure that the working condition of the hydraulic brick machine is stable, general plunger pump overheating or oil leakage, it indicates that the equipment failure, it is necessary to repair and solve, so what are the causes of plunger pump overheating or oil leakage?
Hydraulic brick machine
Hydraulic brick machine plunger pump overheating causes
1, mechanical friction heat: because the moving surface is in a dry friction or semi-dry friction state, moving parts friction heat each other.
2, hydraulic body friction heat: high pressure oil leakage through various gaps to the low pressure cavity, a large amount of hydraulic energy loss into heat.
3, the oil return filter blockage caused by the return oil back pressure is too high, will also cause the oil temperature is too high and the pump body overheating.
4, internal leakage is too large.
Therefore, the correct choice of clearance between moving parts, oil tank volume and cooler can eliminate the phenomenon of overheating and high oil temperature of the pump. In addition, the return oil filter blockage causes the return oil pressure to be too high, which will also cause the oil temperature to be too high and the pump body to be overheated.
Hydraulic brick machine plunger pump oil leakage causes
1, the plunger pump spindle oil seal damage or shaft defects, scratches;
2, piston pump internal leakage is too large, resulting in increased pressure at the oil seal, and the oil seal is damaged or flushed out;
3, the drain pipe is too thin and too long, so that the seal oil leakage;
4、The external oil pipe of the piston pump is loose, the pipe joint is damaged, and the gasket is aging or cracked;
5, variable adjustment structure bolt loose, seal broken.
After finding the cause of hydraulic brick machine plunger pump overheating or oil leakage, we can find out which is the cause of their own equipment failure by elimination, you can target maintenance, the next section we will introduce the solution to the plunger pump overheating, oil leakage solutions.
