Maintenance method

1. Replace seals regularly
The service life of seals is generally one and a half to two years, and they must be replaced in time to ensure the tightness of the seal.
2. Avoid impact pressure damaging components
Impact pressure in the hydraulic pressure should be avoided during operation, as impact pressure will damage components. Each pressure valve and each flow valve must be reasonably adjusted strictly in accordance with the design requirements. After adjustment, the adjusting screws must be tightened securely.
3. Always pay attention to the temperature of the hydraulic station
The working temperature of the hydraulic system oil must not exceed 70°C, and should generally be controlled within the range of 35~60°C. If it exceeds the specified range, the cause should be checked and eliminated.
4. Maintain the quality of hydraulic oil
Select hydraulic oil according to the brand number specified in the instruction manual. The oil must be filtered before refueling. At the same time, the oil quality must be sampled and tested regularly. If the oil quality is found to be unsuitable for use, it must be replaced. Generally, it must be replaced every six months or every 2,000 working hours.
 

Theory

Axial piston pumps generally consist of main parts such as cylinder block, oil distribution plate, plunger and swash plate. There are multiple plungers in the cylinder, and the plungers are arranged axially, that is, the center line of the plungers is parallel to the axis of the transmission shaft, so it is called an axial piston pump. But it is different from the reciproing plunger pump, because its plunger not only reciproes in the pump cylinder, but also the plunger and pump cylinder rotate relative to the swash plate. The plunger contacts the swash plate with a spherical end. There are high and low pressure moon-shaped grooves on the oil distribution plate. They are separated from each other by partition walls to ensure a certain degree of sealing. They are connected to the oil inlet and oil outlet of the pump respectively. There is an inclination angle between the axis of the swash plate and the axis of the cylinder.
