Detailed steps for replacing the accumulator are described

1) before replacing the accumulator, the nitrogen pressure must be determined first, then the filling valve can be unscrewed and the air pressure in the capsule can be determined again. You can then replace the accumulator. If there is nitrogen pressure, you can twist the vent screw on the nitrogen pressure gauge to release the nitrogen before replacing it.

 

2) close the oil stop valve of the accumulator, open the oil stop valve, and then close the oil stop valve after the remaining oil is exhausted.

 

3) release the nut, move the accumulator from the bracket to the ground and lie flat on the ground.

 

4) loosen the stainless steel connector connected to the energy accumulator.

 

5) screw down, loosen and remove the nuts, tighten the nuts A and B, tap the bushing ring and remove.

 

6) push the fungus valve into the shell.

 

7) remove O ring, baffle ring and support ring, and take out (note direction).

 

8) remove the rubber holder and the bacteria valve.

 

9) pull out the capsule.

 

10) clean the outer surface of the new capsule with alcohol.

 

11) place the capsule into the shell. Check whether o-ring (m) is on the air valve seat. The air valve seat is pulled out of the small mouth of the shell and fixed with nut A.

 

12) install the fungus valve, rubber holder and support ring.

 

13) pull the bacteria valve out, and the rubber holder and supporting ring just seal the big mouth of the shell.

 

14) insert O ring (N) and baffle ring into the seam, and insert the sleeve ring.

 

15) install and tighten nut B separately. Install the filling valve on the aeration seat. Pay attention to cleanliness and straightness of copper gasket.

 

16) install screw plug and pay attention to cleanliness and straightness of copper shim.

 

17) fill with nitrogen. Start slowly, and note that the fungus valve should move slowly outward to check for leaks. Air is charged at the prescribed pressure (9.0 + 0.2mpa).

 

18) install the joint and install it on the bracket. Tighten the nut on the joint.

 

19) close the drain stop valve and slowly open the intake stop valve. Stop when you hear the hiss of oil intake. Let the high pressure oil slowly enter the accumulator.
