Maintenance Notes For Hydraulic Oil Pumps

Nov 27, 2018

1. The oil pump uses No. 20 oil.

2. The oil storage capacity must be within the range above the oil window.

3. When refueling and oil change, it must be filtered with oil filter of 80 mesh or more. When replacing, you need to clean the fuel tank. The oil change period is six months.

4. Working oil temperature is 10 degrees Celsius to 50 degrees Celsius.

5. Open the bleed nut before starting the electric pump and open the switch to the unloading position.

6. If the motor temperature is too high during use, it should be stopped. Allow to cool before use.

7. The hydraulic oil pump has been adjusted before leaving the factory, and it is not allowed to be high-profile. When it needs to be re-adjusted, it must be carried out by means of a pressure gauge.

8. The high pressure oil pipe is delivered to the factory and passed the 105MPA test. However, due to the easy aging of the hose, the user should check frequently, usually for six months. The vortex flowmeter is frequently used for three months. When the inspection is carried out, the pressure is 87.5MPA. If there is damage, protrusion or leakage, it cannot be used. .

9. The bearing is usually cleaned once every six months, and grease should be added during assembly.
