A8V hydraulic piston pump Specifications: A8V40,55,64,80,107 Description: A8V bent axis type axial piston variable double pump hydraulic structure Cline, a total of two pump housing, control devices are typically superimposed HP Total power constant control of the hydraulic pump sales, in addition to a separate single pump constant power control. Flow and speed and displacement to correct this, you can put a = stepless variable angle between 25 ° ~ 7 °. Features: between the rotor and the oil pan with oil as a sphere, the movement can automatically pair, the peripheral speed of the lower and higher efficiency. Note: 1. Cleanliness should be maintained for any occasion hydraulic oil; 2. Periodic replacement of the hydraulic oil (working from 1000 to 3000 hours or six months). The pump can be considered controlled variable caused by poor organization, such as a foreign body into the variable hydraulic pump maintenance organization, draw order mark in the control piston, wear marks, scars, resulting in unstable movement of the control piston (4) Check the oil valve deputy vacuum ring worn a step or scar phenomenon A7V78DR2.0LZF00 A7V78DR2.0LZF00 A7V78DR2.0LZF00 (1) output pressure is too low when the pump is self-priming in the state, if the inlet line or system leak hydraulic cylinder, one-way valve when the valve and so have a greater leakage are cause pressure does not rise up A7V78DR2.0LZF00 A7V80LV5.1RSF00 A7V250EL5.1RSF00 A7V40SC5.1LSF00 A7V78LV2.0RPF00 A7V355LV2.0RZF00 piston work on fuel injection pump camshaft cam and under the action of the plunger spring, forcing the plunger for the upper and lower reciprocating motion, thus completing the task of pumping power source pumps | pumps | hydraulic preferred by the Jinan Jing Jing Chong Chong Hydraulic Machinery Limited.
