In the process of using the plunger pump, you will always encounter various problems. For example, the oil displacement of the plunger pump is not zero when the plunger pump is in the neutral position. What should I do if I change it? Next, the plunger pump manufacturer will tell you about the maintenance techniques for common failures of the plunger pump.
1. The output flow of the plunger pump is insufficient: the reason is that the resistance on the suction pipe is too large or the oil supplement is insufficient, which leads to insufficient suction. Treatment method: reduce the excessive resistance on the suction line, or add oil.
2. Excessive leakage: The reason is that the gap of the pump is too large and the seal is not good. Treatment method: You can judge whether the pump is damaged by checking the hydraulic oil in the pump body to see if the hydraulic pressure is mixed with foreign matter.
3. The tilt angle of the swash plate is too small, resulting in a small displacement of the pump. Treatment method: adjust the variable piston and increase the inclination of the swash plate.
The above is the troubleshooting of the plunger pump, do you understand?
