Piston pump basics

The plunger pump, as its name suggests, relies on a plunger as the main working component of the pump. The principle is no stranger to everyday life, such as syringes for doctors and hand-pressed water wells. The syringe used by doctors is the most vivid, consisting of a needle (cylinder), a piston (plunger), and a needle. The working principle is that the movement of the piston (plunger) in the needle tube (cylinder) changes the volume in the needle tube (cylinder) and pushes the medicine (hydraulic medium) out of the needle tip (pump port). The basic principle of the plunger pump is similar: by moving the plunger in the cylinder, changing the volume change in the cylinder, pushing the hydraulic medium out of the cylinder.

Travel motor

Failure phenomenon judgment Cause handling and countermeasures There is no high-pressure oil on the inlet side of the motor, and the plunger cannot be switched. Check whether there is high-pressure oil on the motor inlet side, check the cause of the malfunction of each machine, and check the repair. Check the motor. Pressure, but the sharp-edged orifice of the pilot oil passage is blocked by foreign matter, and the plunger cannot be switched.

Plunger pump efficiency

Efficiency is now pursued by many manufacturers. After the work efficiency has been improved, the production capacity of the enterprise will certainly be improved, and the development of the enterprise will be better and better. Under normal circumstances, the efficiency of the enterprise is also related to the equipment of the enterprise. Take the axial piston pump. The axial piston pump you use is inefficient, so the production speed will naturally not go up. Face this What kind of situation should we solve?
