Keep a detailed record of the cleaning and treatment process, including the cleaning agent used, the type and amount of disinfectant, the amount of liquid discharged and the treatment method, the amount of dirt collected and the treatment method. These records facilitate subsequent traceability and management.

Vertical pipeline pump suction range is generally 40 meters. Under normal circumstances, if it is under one kilogram of pressure, then the lift of the vertical pipeline pump is 10 meters, if it is under four kilograms of pressure, then the lift of the vertical pipeline pump can generally be as high as 40 meters, so the suction of the vertical pipeline pump can generally reach 40 meters.

Check and repair according to the above method, should be able to solve the problem of self-priming pump buzzing but not water. If the problem persists, it is recommended to contact maintenance personnel for inspection and repair.

Submersible sewage pump power supply voltage is too low because the power supply voltage is too low, resulting in the submersible sewage pump can not start, the submersible sewage pump is usually required to 380V power supply voltage, should be adjusted to more than 342V. When the submersible sewage pump is used in the emergency situation of flood prevention and drainage, and the power supply voltage is lower than 342V.

In the coal washing system, the selection of filter press feed pump is a key link, which directly affects the efficiency of the filter press and the stable operation of the whole system.

The working principle of submersible axial flow pump is mainly based on the head theory in aerodynamics. When the impeller rotates at a high speed, the liquid particles in the pump body will be affected by the axial lift force from the impeller, making the water flow along the axial direction.

Self-priming pump is often used in pumping, water supply, pressurization and other work under various working conditions, with simple structure, small volume, easy installation, use and maintenance is relatively simple. In order to be able to choose the right self-priming pump and make it work properly, we need to pay attention to some key elements.

The daily maintenance of the slurry pump is essential to ensure its stable operation. The following are detailed recommendations on the daily maintenance of slurry pumps

A submersible sewage pump is a device used to treat wastewater by efficiently discharging it to a sewage treatment plant or other designated location. Submersible sewage pumps are widely used in various industrial fields and cities, which can treat and discharge wastewater and reduce pollution to the environment. The following describes how to treat wastewater efficiently using submersible sewage pumps.

Horizontal slurry pump is a single stage, single suction cantilever type centrifugal pump, mainly composed of pump body, impeller, pump cover, bearing body, bracket and other parts. The import and export are on the same horizontal axis, the pump body is horizontally open, and the import and export pipes do not need to be removed during maintenance, and the maintenance is convenient.
