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.

Working principle of double suction pump

2025/08/22

Mainly based on pressure difference and centrifugal force. When the double-suction pump starts working, both of its inlets form negative pressure areas, and the liquid is driven by the pressure difference to flow from the supply system to the pump's suction inlet. After the liquid enters the pump chamber through the suction inlet, the pump rotor begins to rotate.

Structural Composition of the Desulfurization Pump

2025/08/22

Pump head section: It is one of the core structures of the desulfurization pump, mainly including the front and rear pump casings, volute casing, front and rear wear plates, and impeller components. These components work together to ensure the pump's efficient and stable operation.

Application fields of slurry pumps

2025/08/22

Slurry pumps are widely used in industries such as mining, power plants, metallurgy, chemical engineering, building materials, and petroleum. Specifically, in the mining industry, slurry pumps are used for ore transportation and tailings treatment; in the power industry, they are mainly used for hydraulic ash removal and ash slag transportation in thermal power plants; in the metallurgy industry, they are used for slurry transportation and liquid handling during smelting processes; in the chemical industry, they are used to transport slurries containing corrosive solid particles.

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.
