The Engineering submersible sewage pump belongs to a type of high head submersible sewage pump, with a maximum head of 72 meters. It has the characteristics of reasonable design, excellent performance, high efficiency, durability, safety and reliability, and easy maintenance.
This series of electric pumps consists of three parts: water pump, seal, and electric motor. The electric motor is located at the upper part of the electric pump and is a single-phase or three-phase asynchronous motor; The water pump is located at the lower part of the electric pump and has a flow channel impeller and volute structure; Mechanical seals are used between the water pump and the electric motor, and O-ring oil resistant rubber seals are used for static sealing at each fixed stop to ensure the reliability of the electric pump. The rotor shaft of the electric pump adopts heat treatment technology to ensure more reliable mechanical strength of the shaft, which can effectively improve the wear resistance and corrosion resistance of the shaft, and also facilitate the maintenance and disassembly of the impeller. Electric pumps with a head of over 70m are equipped with check valves to ensure the safety of the pump during shutdown. It is recommended that users equip a fully automatic safety protection controller to protect the pump from water leakage, leakage, phase loss, overload, etc., in order to ensure the safety and reliability of the product.
This series of electric pumps is widely used in industrial, agricultural, mining, construction, municipal environmental protection and other places. It can pump liquids containing solid particles or soft solid substances such as short fibers, paper scraps, sediment, etc., such as mud water, grey water, domestic wastewater, sewage, feces and urine. It is an ideal water conservancy equipment for enterprise drainage, river dredging and construction sites, but it is not suitable for occasions with explosion-proof requirements. Some specifications use flow channel impellers, greatly improving the anti clogging ability of the water pump; Some specifications adopt the full head theory design to enable the electric pump to maintain overload free operation under normal conditions, effectively extending the service life of the motor.
