What is the cause of the water leak of fire pump? How to solve it?

1. The fire pump sealing ring loses its elasticity due to long-term use. At this time, the sealing ring can be taken out, and cut another piece of paper or cloth with a thickness of 0.3 to 0.5 mm into a pad slightly larger than the original sealing ring and install it in the groove, then install the original sealing ring.
2. The rubber sealing ring in the nylon sealing seat is worn out. The sealing ring can be taken out and exchange the orientation equipment. If the tension spring on the sealing ring loses elasticity or is cracked, remove the tension spring, and tie a steel wire or wire of appropriate diameter tightly.

4. The sealing ring between the sealing box and the cast iron loses its elasticity. You can take the sealing ring out of the cast iron groove, find a piece of hard paper with a thickness of 0.6 to 1 mm and cut it into the same specification, pad it in the groove, and then put the seal ring into it.
5. If the rubber sealing ring of the oil hole is damaged, find a piece of tape, cut it into a hole slightly larger than the bolt, add a flat washer on top, and put it in the oil hole of the bolt together.
