How to better maintain the electric hydraulic pump

Electric hydraulic pump is widely used, the composition of the structure is complex, for the production and life belt to a larger convenience, on the maintenance of hydraulic oil pump, Xiaobian summed up a few small knowledge, welcome to share.

1. the oil storage capacity must be above the oil window;

2. before starting the electric pump, open the bleed nut, open the switch and put it in the unloading position;

3. oil pump uses No. 20 engine oil;

4. each refueling and oil change, you must use more than 80 mesh filter oil filter, replace the need to clean the tank. The oil change period is six months;

5. working oil temperature 10 degrees Celsius to 50 degrees celsius;

6. the motor temperature is too high during use, should stop using. Use it after cooling yourself;

7. high pressure tubing factory, through the 105MPA test. But because the hose easily aging, so users need to regularly check, usually six months, vortex flowmeter frequently used for three months, 87.5MPA pressure test, if there is damage, heave, leakage phenomenon, you can not use;

8. hydraulic oil pump has been adjusted before leaving factory, not arbitrarily high profile, need to re adjust, you must use the pressure gauge;

9. bearings generally cleaned once every six months, need to add grease when assembling.
