What are the causes of water leakage from R Hot Water Circulation Pump products

(1) When installing R Hot Water Circulation Pump products, the water seal seat assembly was not installed in place, causing the water pump to continue to leak. Since there is a water retaining ring on the pump shaft corresponding to the inspection hole, when the water seal leaks, the cooling water will be thrown out and dripping from the inspection hole of the pump when it encounters the water retaining ring along the pump shaft, which can prevent Cooling water flows into the bearing to destroy lubrication. In addition, when replacing the water retaining ring, care is not taken to remove the poor combination and sealing between the pump body and the pump cover, which will also cause the water pump to leak.

(2) The working environment of construction machinery is harsh, and it is easy to cause uneven wear of the bakelite gasket and the end face of the bushing; the spring is immersed in water for a long time, which is easy to rust, the elasticity is reduced, and it can also cause water leakage.

(3) In winter, if the water is forgotten to be discharged or the water is not clean, and the temperature is too high when the water is discharged, the water vapor in the cooling system freezes after condensation, which may cause the pump body to be frozen and cracked, resulting in water leakage.

(4) The machine is old, and the internal parts of the water seal are worn, corroded and aged, which are also the reasons for the leakage of R Hot Water Circulation Pump products. When the construction machinery is parked for a long time, because there is no cooling water in the engine, the bakelite gasket will be deformed due to drying and shrinkage; after adding water, the bakelite gasket will expand but cannot be completely restored to its original state, which will inevitably cause a small amount of water leakage. In addition, for the newly installed water pump, the bakelite gasket and the cast iron bushing have not been completely run-in, which will also cause a small amount of water leakage from the water pump.
