Detailed Explanation of the Working Principle and Models of Pipeline Pumps

The working principle of a pipeline pump is to utilize the power of an electric motor, through the rotation of the impeller, to draw the liquid into the pump body and then transport it through the pipeline to the desired location. The specific working principle is as follows:
1. Inlet stage: When the electric motor is started, the impeller begins to rotate. The air inside the impeller is forced to move, creating negative pressure, which causes the liquid in the pipeline pump to be sucked into the pump body.
2. Pushing stage: As the impeller rotates, the liquid is pushed to the pump's outlet. During this process, the rotational speed of the impeller and its geometric shape affect the flow rate and pressure of the liquid.
3. Pump body and pipeline: The liquid flows from the pump body into the pipeline and is transported to the target location. The diameter, length, and material of the pipeline affect the efficiency and performance of liquid transportation.
It should be noted that pipeline pumps have certain working conditions and limitations, such as pump head limitations, requirements for liquid temperature and viscosity, etc. In practical applications, it is necessary to select the appropriate pump type, materials, and accessories to meet the working requirements.
Here are some common types of pipeline pump introductions:
1. DL Series Vertical Multi-stage Centrifugal Pump
This type of pump is suitable for industrial and urban water supply, fire protection, circulating cooling, boiler water supply, etc. Its main structural feature is that it is composed of multiple centrifugal pump stages, which has the advantages of saving floor space, low noise, more hygienic, and more reliable.
Technical parameter table:
Maximum flow rate: 240 m³/h Maximum head: 305 m Power range: 3 - 200 kW
2. ZW Series Self-priming Sewage Pump
This type of pump is suitable for urban sewage, factory and enterprise sewage, slurry, etc. Its main structural feature is self-priming, without the need for installing a bottom valve and filling water, and because of the wide flow channel, it can transport various slimes, fibers, and solid blocks, and there will be no jamming phenomenon during transportation.
Technical parameter table: Maximum flow rate: 800 m³/h Maximum head: 80 m Power range: 2.2 - 55 kW
3. QP Series Pneumatic Diaphragm Pump
This type of pump is suitable for transporting various corrosive media, viscous liquids, various concentrations of acids, alkalis, salts, etc., as well as liquids with particles and solids.
Technical parameter table:
Maximum flow rate: 30 m³/h Maximum head: 50 m #Pump
4. IS Series Single-stage Single-suction Centrifugal Pump
This type of pump is suitable for urban water supply, drainage, water supply and mining, metallurgy, etc. Its main structural feature is excellent noise reduction and corrosion resistance, suitable for transporting clear water and liquids with physical and chemical properties similar to clear water.
Technical parameter table:
Maximum flow rate: 1100 m³/h Maximum head: 125 m Power range: 0.55 - 315 kW
