EP100 22T Engine Water Pump 16100-2833 For HINO Diesel Engines Parts

Unable to absorb water

The reason is that there is air in the pump body or there is air accumulation in the water inlet pipe, or the bottom valve is not closed tightly enough to fill water, the vacuum pump packing leaks seriously, and the gate valve or flap valve is not closed tightly. Troubleshooting: First, increase the water pressure, then fill the pump with water, and then start the machine. At the same time, check whether the check valve is tight and whether there is air leakage in the pipeline and joints. If air leakage is found, apply lubricating oil or mixed paint on the joints after disassembly and tighten the screws. Check the oil seal ring of the water pump shaft and replace it with a new one if it is seriously worn. The pipeline leaks water or air. The nut may not be tightened during installation. If the leakage is not serious, cement or cement slurry mixed with asphalt oil can be applied at the place with air or water leakage. For temporary repairs, apply some wet mud or soft soap. If there is water leakage at the joint, the nut can be tightened with a wrench. If the water leakage is serious, it must be disassembled and replaced with a cracked pipe; Reduce the lift and press the nozzle of the water pump into the water for 0.5m.

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.
