Water ring vacuum pump mechanical seal replacement disassembly steps: 1, remove the water ring vacuum pump mechanical seals at both ends of the cooling water pipe; 2, remove the power side of the pulley (replace the non-mechanical end of the mechanical seal without this step); 3, respectively, Remove the mechanical seals on the power end and the non-mechanical end from the shaft and pay attention to light and light lifting. This step is especially important to avoid damage to the intact mechanical seal. (Note: this step is also necessary if the bearings on both ends are to be repaired separately.) 4. Remove the bearing gland to replace the mechanical seal end and remove the bearing lock back cap. 5. Use the top wire to connect the bearing housing together with the bearing Top removed. (In this case, it is necessary to hoist the shaft from the disassembly side with a hoist to facilitate the top of the bearing); 6. Remove the old mechanical seal from the shaft; 7. Carefully cover the new mechanical seal after inspection; 8, cleaning check bearing is intact, check the bearing clearance is appropriate; 9, the bearing, bearing seat back to the shaft, and bearing grease, tighten the inner cap locking cap, fitted with bearing gland One step also need to hoist with the shaft); 10, try to see if the car is easy, pay special attention to this process does not damage the mechanical seal; 11, respectively, both ends of the mechanical seal from the shaft back into the sealed box inside; , Reinstall the pulley (non-power end without this step); 13, back to the condensate water pipe, into the condensate leakage after the disc; 14, maintenance is completed, the work place cleared.
