W04D Radiator Water Pump 16100-E0341 For HINO Diesel Engines

Water pump is a kind of machinery to transport liquid or pressurize liquid. It transmits the mechanical energy or other external energy of the prime mover to the liquid to increase the energy of the liquid. It is mainly used to transport liquid, including water, oil, acid-base liquid, emulsion, suspended lotion and liquid metal.

It can also transport liquid, gas mixture and liquid containing suspended solids. Technical parameters of pump performance include flow, suction head, head, shaft power, water power, efficiency, etc; According to different working principles, it can be divided into volume pumps, vane pumps and other types. The positive displacement pump uses the change of the volume of its working chamber to transfer energy; Vane pump uses the interaction between rotating blades and water to transfer energy, including centrifugal pump, axial flow pump and mixed flow pump.

1. If the water pump has any small fault, remember not to let it work. If the packing of the water pump shaft is worn, it should be added in time. If the water pump is used continuously, it will leak air. The direct impact of this is that the energy consumption of the motor will increase and the impeller will be damaged.

2. If the pump vibrates strongly during use, it must be stopped to check the cause, otherwise the pump will be damaged.

3. When the bottom valve of the water pump leaks, some people will fill the inlet pipe of the water pump with dry soil and flush the water to the bottom valve. This is really undesirable. Because when the dry soil is put into the water inlet pipe and the water pump starts to work, the dry soil will enter the pump, which will damage the impeller and bearing of the water pump, thus shortening the service life of the water pump. When the bottom valve leaks, it must be repaired. If it is serious, it needs to be replaced with a new one.

4. Pay attention to the maintenance of the water pump after use. For example, when the water pump is used up, drain the water in the water pump. It is best to remove the water pipe and wash it with clean water.

5. The tape on the water pump should also be removed, washed with water and dried in the light. Do not put the tape in a dark and humid place. The adhesive tape of the water pump must not be stained with oil, let alone some sticky things on the adhesive tape.

6. Carefully check whether there are cracks on the impeller and whether the impeller is fixed on the bearing. If there are cracks and looseness, repair them in time. If there is dirt on the water pump impeller, clean it up.
