Assembly and disassembly of pipeline fire pumps:
Before the assembly of the fire pump, each part shall be inspected. The mating surface of the parts, especially the friction surface of the mechanical seal, shall be cleaned. The sealing surface shall not have obvious scratches, cracks, bumps, etc. If any of the above defects should be replaced.
Pipeline fire pump assembly:
1. Press the retaining ring into the motor shaft and fasten the middle seat to the motor with bolts.
2. After applying Vaseline and other lubricants to the apron of the mechanical seal static ring, press the static ring assembly into the middle seat and coat the sealing surface with clean grease, install other sealing parts, and install the flat keys. Impeller and retaining washers, and tightened with bolts.
Note: The seal ring of the mechanical seal static ring is easily deflected when installed. This will cause the seal to leak and should be carefully checked during installation. Apply a suitable amount of grease to the sealing surface of the middle seat and attach it. Circles. installation. When the ring is formed, the sealing ring can easily come off and fold. Be careful to avoid water leakage.
3. Lift up the motor assembly and move the impeller downwards into the fire pump body slowly. Then fasten it with bolts and install the plugs and bleed plugs.
4. Rotate the rotor with your hand to check for stuck conditions.
Pipeline fire pump dismantling:
Follow the reverse procedure for installation.
Note: When disassembling the mechanical seal, do not hit the stationary ring directly with a hammer or a hammer. Use wood to gently tap and remove the stationary ring slowly. If dislodgement is difficult due to accumulation of dirt, it should be cleaned before disassembly.
