Precautions for A7V inclined shaft axial piston pump

 

1、 The rotation of the pump shaft should always be clockwise (when viewed from the shaft end). If the user needs to rotate counterclockwise or use it as a motor, it must be specified at the time of ordering.

 

The pump and motor are connected by an elastic coupling and require concentricity, otherwise noise, reduced efficiency, and other faults may occur.

 

The pump has a certain self-priming capacity and can be installed on a storage tank with a suction height not exceeding 0.5 meters. However, for pumps with a flow rate greater than 160L/min, it is recommended to use self-priming backflow.

 

Before starting the pump for the first time, clean working fluid must be injected into the pump casing through the oil nozzle, otherwise it is not allowed to start.

 

The oil pump housing is required to withstand a certain amount of pressure, but due to the limitations of the rotating sealing ring and the upper flange sealing gasket, the pressure inside the housing cannot exceed 0.05 millipascals. Therefore, the return pipe cannot be too thin and can directly return to the oil tank.

 

For the working medium, it is recommended to use domestically produced 32 or 46 hydraulic oil, or hydraulic oil with E50=3-5 viscosity index greater than 90, with a normal working oil temperature of 10-65 ℃.

 

Users can select the motor based on the calculated driving power of the oil pump according to the actual usage load. Calculation formula: N=Q × P/60n, where Q - actual flow rate (L/min) P - actual working pressure (MPa) n - total efficiency (0.8-0.9) CY14-1B series pumps are driven by variable head (inclined plate) variables and rotate in the cylinder as a vehicle oriented piston pump. Due to the optimal oil film thickness design of hydraulic static balance between the sliding shoes of the plunger head and the transmission head, as well as between the oil distribution plate and the cylinder body, the two pairs of motion pairs are in a pure hydraulic friction state, and the heavy thrust bearings are eliminated. Therefore, compared with other types of pumps, it has the advantages of simple structure, small volume, light weight, high efficiency, long service life, and strong self-priming ability. This machine is suitable for hydraulic transmission of machine tools, forging, metallurgy, engineering, mining and other machinery. This pump can be used for hydraulic motors by simply replacing the oil distribution plate of the motor.
