The water pump plays an important role in daily life. It can make the water pump suck the low liquid level liquid or water into the pump cavity at a high place and throw the liquid out at a high speed through the impeller, so as to achieve the purpose of transporting and promoting the liquid. If the pump is sometimes unqualified or the service life is too long, and the self-priming capacity is reduced, it will not achieve the purpose we need. Therefore, small pump manufacturers think that understanding and mastering the methods to improve and increase the self-priming capacity of the self-priming pump appears especially important.

The following introduction of small pumps will introduce the methods to increase the service life of the pumps and improve the self-priming ability.

1. A vacuum is set on the suction pipe of the water pump. Before the water pump is started, the vacuum pump is started first, so that the suction pipe of the water pump is filled with water first to ensure that the water pump starts automatically and quickly. This type of water absorption requires a complete automatic control system to ensure normal operation.

2. Reduce the bends, drop height and horizontal interval of the inlet pipe.

3. Set up the suction tank before the pump. Small water pump manufacturers need to install a suction tank on the suction pipe of the pump. Before the pump is operated, the tank should be filled with water manually. After the operation stops, the height of the suction tank’s water inlet pipe is higher than the height of the water surface in the pipe. The water level in the pool is lower than the height of the water level in the tank, and the water in the tank will not flow back into the pool. Therefore, a certain amount of water can be stored in the suction tank, and because of the height of the outlet pipe of the suction tank (that is, the suction pipe of the water pump) It is lower than the water level in the pipe, so it can ensure that the suction pipe of the water pump is filled with water. When the water pump is running again, the water in the water tank is pumped away by the water pump, and negative pressure appears in the tank, and the water in the pool is under the action of atmospheric pressure. Add to the suction tank, through the suction tank in the pool.

4. Install a suction bottom valve at the end of the suction pipe. The suction bottom valve is actually a check valve. It ensures that the water flow can only enter the suction pipe from the pool and cannot flow back. Therefore, if the suction pipe is full of water, although the pump axis is higher than the working water level of the pool, it is because there is water absorption. The function of the bottom valve prevents the water in the suction pipe from flowing into the pool, so that the suction pipe is always filled with water, ensuring that the water pump can be started automatically and quickly.

The above is how to extend the service life of the pump and improve its self-priming ability. Hope to provide some help to your operation and use.
