QW submersible sewage pump specification sales submersible sewage pump

Description :

　　QW submersible sewage pumps are mainly used in industries such as municipal engineering, industry, hospitals, construction, hotels, and restaurants. Used for discharging solid and various long fiber sludge, wastewater, and urban domestic sewage (including corrosive and erosive media), it has the advantages of high efficiency, anti entanglement, no blockage, automatic coupling, high reliability, and automatic control. It has unique functions in discharging solid particles and long fiber garbage. It can automatically control the water level according to user requirements, and is equipped with automatic protection devices and control cabinets, dual rail automatic installation systems, etc.

　　QW submersible sewage pump usage conditions

　　1. Motor rated voltage 380V, frequency 50HZ three-phase AC power supply.

　　2. The temperature of the conveying medium shall not exceed 40 ° C.

　　3. The pH value of the conveyed liquid medium is 4-10.

　　4. The volume ratio of solid phase in the conveying medium is below 2%.

　　5. The density of the conveying medium is less than 1.2 × 103Kg/m3

　　Performance characteristics of QW submersible sewage pump

　　The QW submersible sewage pump has a compact structure and is equipped with various status displays and protective devices, ensuring safe and reliable operation of the pump.

　　1. Adopting cable sealing design eliminates the hidden danger of cable leakage.

　　2. The stator adopts F-class insulation and is equipped with thermal protection components.

　　3. Pumps above 18.5KW are automatically cooled by external circulating water to ensure safe operation of the electric pump at lower water levels.

　　4. A float switch is installed at the bottom of the motor chamber to monitor the mechanical seal on the motor side.

　　5. An oil-water probe is installed at the upper end of the oil chamber of the pump and motor to monitor the mechanical seal on the water pump side. Once there is a water leak, the control system will alarm for protection.

　　6. Bellows type double end mechanical seal, with sealing materials of tungsten carbide, silicon carbide and hard alloy, prevents water from entering the motor and ensures safe and reliable operation of the motor.

　　7. The secondary impeller is used to balance the external pressure of the mechanical seal, prevent water from entering the oil chamber, and thus extend the service life of the electric pump.
