product description

HL-A2FM fixed motor

Features:

Mobile machinery and hydraulic components;
Axial piston quantitative motor with inclined shaft structure, suitable for open and closed circuits of hydrostatic transmission;
The output speed of the hydraulic motor is related to the pump flow and motor displacement;
The output torque increases with the pressure difference between the high and low pressure sides and the increase of the displacement;
Choose long-life, high-precision bearings and park seals;
It has the characteristics of compact structure design, light weight, low noise and high efficiency;

Note: 1) The data in the table are theoretical values, without considering the volumetric efficiency and mechanical efficiency; the values ​​are rounded.

3.2 Working pressure range

The maximum pressure of port A or B is shown in the following table:

Specification 28~125

Shaft A, Z

Shaft extension B, P

Nominal pressure PN

40Mpa

35Mpa

Maximum pressure Pmax

45Mpa

40Mpa

Note: 1. For shaft ends Z and P, if the drive shaft has a strong force, the nominal pressure only allows PN=31.5 Mpa
2. Corresponding to the shaft end Z, displacement from 28 to 56: PN=35Mpa Pmax=40Mpa
3. The pressure of port A and B does not exceed 70MPa

3.3 Oil flow direction (viewed from the shaft end)
  1. a. Clockwise, A flows to B

  2. b. Counterclockwise, B flows to A

3.4 Speed ​​range

In occasions where smooth operation is required, the minimum speed n min cannot be lower than 50 rpm, and the maximum speed is in accordance with the parameter table.
Precautions:

  1. a. During the trial operation, the pump body must be filled with oil and kept full during work;

  2. b. The motor must be started at low speed and no load until the system is completely deflated;

  3. c. In order to reduce noise, all connecting pipes are recommended to be isolated from the fuel tank with flexible components;

  4. d. The temperature at any point in the oil circuit must not exceed 115°C;

  5. e. The allowable value of case drain pressure is absolute to the motor speed. The short-time allowable absolute pressure peak value P k≦0.6Mpa; the case drain pressure during average continuous operation shall not exceed the absolute pressure 0.3Mpa;

  6. 4. Implementation standards of hydraulic motors
