Keep the equipment clean, dry, free of oil stains, and leak-free. Regularly check the water pump's operating sound, vibration, and leakage conditions.

When selecting a water pump, the following points need to be considered

2025/08/22

Determine flow rate: Calculate the flow rate based on the specific water usage or liquid transport requirements. Determine head: Calculate the vertical height from the water source to the destination, taking into account pipe resistance losses.

Water pumps have wide applications in multiple fields

Agricultural irrigation: extracting groundwater or river water sources for irrigation. Construction engineering: used for concrete delivery, building drainage, fire protection systems, etc.

The working principle of a water pump varies depending on the type

2025/06/26

Vane Pump: Transfers mechanical energy to the fluid through rotating vanes. Common types include centrifugal, axial flow, and mixed flow pumps. Among them, the working principle of the centrifugal pump is that the impeller's high-speed rotation generates centrifugal force, which throws the liquid outward into the volute casing. After forming a vacuum, water from the reservoir is drawn into the replenishment space through the suction pipe under atmospheric pressure, enabling continuous suction and discharge of water. The axial flow pump uses the thrust generated by the impeller's high-speed rotation to lift water. The mixed flow pump combines the principles of centrifugal force and lift.

There are various types of water pumps based on different classification criteria.

According to the pump shaft direction: it can be divided into horizontal, vertical, and inclined types. According to the casing split type: it is divided into radial split and axial split types. According to the number of stages: it is divided into single-stage and multi-stage (multi-level).

Precautions When Using Sewage Pumps

2025/06/26

When using a sewage pump, ensure it is installed correctly and securely fixed to avoid vibration and noise during operation.

A water pump is an important fluid transport device widely used in multiple fields.

2025/06/26

A pump transfers mechanical energy from the prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acidic and alkaline solutions, emulsions, suspensions, liquid metals, etc. It can also transport liquid-gas mixtures and liquids containing suspended solids.

Maintenance and Care of Submersible Pumps for Wells

2025/06/26

Regularly test and record the insulation resistance. If the resistance is below the specified value, the cause should be identified promptly and the slurry pump should be treated accordingly.

Analysis of the main differences between submersible pumps and centrifugal pumps

2025/06/26

Working principle of the submersible pump: Before starting the pump, the suction pipe and the inside of the pump must be filled with liquid. After starting the pump, the impeller rotates at high speed, and the liquid inside rotates together with the blades. Under the action of centrifugal force, the liquid is thrown outward from the impeller. The ejected liquid gradually slows down in the pump casing diffusion chamber, and the pressure gradually increases, then flows out from the pump outlet and discharge pipe. At this time, a vacuum low-pressure zone without air or liquid is formed at the center of the blades because the liquid is thrown outward. Under the atmospheric pressure on the surface of the liquid pool, the liquid flows into the pump through the suction pipe. In this way, the liquid is continuously drawn up from the liquid pool and continuously discharged from the discharge pipe.
