| WORKING PRESSURE | Nominal pressure40MPa,Peak Pressure 45MPa |
| CONTROL METHOD | Type NV, without controls DG-hydraulic control, direct control EZ-Electrical two-point control, with switch electromagnet HD - Hydraulic control, related to pilot pressure HW - hydraulic control, mechanical servo EP-electrical control with proportional solenoid DA - hydraulic control, related to deceleration |
| CHARACTERISTIC | ◆Swashplate type axial piston variable displacement pump for closed
circuit hydrostatic transmission ◆The flow is proportional to the driving speed and displacement and can be infinitely variable; ◆The flow rate increases from zero to its maximum value with the swash plate swing angle; ◆Swing the swash plate over the neutral position can smoothly change the flow direction of the liquid; ◆Multiple variable modes that are easy to match with various control and regulation systems; ◆The pump is equipped with two relief valves on the high pressure oil side to protect the hydrostatic transmission (pump and motor) from overloading; ◆The high pressure relief valve also has the function of oil filling valve; ◆Built-in auxiliary pump is used as charge pump and control pump; ◆The maximum charging pressure is limited by a built-in charging relief valve; ◆Full series with built-in pressure shut-off valve; |
Maintenance
1. Regularly replace hydraulic oil: Hydraulic oil is an important part of the hydraulic system. It is very important to regularly replace and maintain the cleanness and proper viscosity of the hydraulic oil. Regularly check and replace hydraulic oil according to the excavator manufacturer's recommendations, ensuring you are using the correct specification and brand.
2. Regularly check the quality of the oil: Regularly check the quality of the hydraulic oil, including checking for moisture, impurities and contaminants. Use appropriate oil filters and oil analyzers to ensure the quality of your hydraulic oil is up to standard.
3. Check the seals of the hydraulic pump: The seals of the hydraulic pump (such as O-rings, sealing rings, etc.) may be worn or damaged during operation, causing hydraulic leakage. Regularly inspect and replace hydraulic pump seals to ensure good sealing performance.
4. Check the filter element of the hydraulic pump: The filter element of the hydraulic pump is used to filter impurities and particles in the hydraulic oil. Regularly check and replace the filter element of the hydraulic pump to ensure normal hydraulic oil flow and protect the hydraulic pump.
5. Pay attention to the temperature of the hydraulic pump: Overheating of the hydraulic pump may affect its performance and life. Ensure that the cooling system of the hydraulic pump operates properly and avoid excessive operating temperatures.
6. Regularly check the vibration and noise of the hydraulic pump: Abnormal vibration and noise may indicate problems with the hydraulic pump. Regularly check the vibration and noise of the hydraulic pump and deal with any abnormalities in a timely manner.
