How to use and precautions for self-priming water pumps

The self-priming water pump is a commonly used type of water pump, widely used in household, agricultural and industrial fields. It has the characteristics of self-priming, corrosion resistance, small size and simple structure, so it is favored by users.

How to use self-priming water pumps

1. Preparation

Before using a self-priming water pump, first make sure that the outside and water inlet of the water pump are clean and free of debris. Check whether the power cord of the water pump is connected correctly and whether the voltage meets the requirements.

2. Start the water pump

After plugging in the power, press the start button to start the water pump. Before starting, make sure that the pressure controller of the water pump is in the off state to avoid damage caused by excessive pressure.

3. Connect the water inlet pipe

Connect the water inlet pipe to the water inlet of the water pump. The water inlet pipe should be kept sealed to ensure that there is no water leakage. In addition, the length of the water inlet pipe should be as short as possible to avoid excessive water suction height of the water pump.

4. Self-priming process

After starting the water pump, it will automatically undergo a self-priming process. The self-priming time is generally 2-3 minutes, during which the sound of the water pump working can be heard. During this period, do not close the water inlet valve to avoid affecting the self-priming effect.

5. Check the pump body temperature

During the self-priming process, you can regularly observe the working condition of the water pump. If the temperature of the water pump is found to be too high, it should be stopped immediately for inspection to avoid damage to the water pump due to overheating.

6. Adjust the pressure controller

After the water pump self-primes, the pressure controller can be adjusted appropriately to make the operating pressure of the water pump meet the actual needs. However, before adjusting the pressure controller, the machine should be shut down first to avoid danger caused by improper operation.

7. Shutdown

When the water pump is not needed, it should be shut down in time. Before shutting down, the water inlet valve should be closed first, and then the stop button should be pressed. After the water pump stops running completely, the power plug can be unplugged.

Precautions for self-priming water pumps

1. Avoid idling

Before starting the water pump, make sure that the water pump has enough water to avoid idling. Idling will cause the water pump to lose its self-priming ability and even cause damage.

2. Prevent dry burning

When using a self-priming water pump, ensure that there is always enough water inside the water pump to avoid dry burning. Dry burning can damage the water pump impeller, mechanical seal and other components, reducing the service life of the water pump.

3. Regular inspection

Regularly check the working status of the water pump, including checking whether the power cord, pressure controller, mechanical seal and other components are normal. If any abnormality is found, it should be repaired or replaced in time.

4. Prevent blockage

The water inlet of the self-priming water pump should be kept clean to avoid blockage by debris. If there is a blockage in the water inlet, it should be cleaned immediately to ensure the normal operation of the water pump.

5. Prevent freezing

In the cold winter, if the water pump is not used for a long time, the water in the water pump should be drained to prevent the water pump from being damaged by ice.

Summary: The use and precautions of the self-priming water pump are what we need to understand and master when using the water pump. Through the correct use and precautions, we can ensure the normal operation of the water pump, extend the service life of the water pump, and provide convenience for our life and work.
