Fast moving submersible electric pump

The QZ type axial flow submersible pump and QH mixed flow submersible pump are submersible electric pumps with YQGN type submersible motors and ZLB type vertical traditional axial flow pump sections, which are coaxial driven as a whole. Can operate in water for a long time. The motor is a dry type fully enclosed submersible three-phase asynchronous motor with an IP68 protection level, capable of continuous and intermittent operation at 24 hours per day. Due to the integration of the motor and water pump, there is no need for the labor-intensive and time-consuming assembly process of the motor transmission mechanism water pump axis alignment on the installation site. The on-site installation is simple, convenient, and fast.

Due to diving into the water for operation, it can greatly simplify the geotechnical and structural engineering of the pumping station, reduce the amount of work, shorten the construction period, and save 30-40% of the project cost.

Low noise, no high temperature inside the pump station, improving the operating environment. It can be built as an all underground pump station according to requirements, maintaining the environmental appearance of the ground. It is an environmentally friendly electromechanical product.

Easy to operate, easy to achieve remote control and automatic control. Supporting the use of our company's SY series intelligent protection controller and comprehensive automation control system and software specifically developed for submersible pumps, ensuring safe and reliable operation of the submersible pump unit and smooth start-up after leisure period; Enable the operation of pump stations to be unmanned and with fewer people on duty.

QZ type axial flow submersible pump and QH type mixed flow submersible pump are suitable for water conservancy flood control and drainage, agricultural drainage and irrigation, municipal water supply and drainage, sewage treatment, dock lifting and precipitation, power station water supply and drainage, regional water diversion, ecological environment water system governance and other fields. Axial flow submersible electric pumps are suitable for low head and high flow situations. Mixed flow submersible electric pumps have high efficiency and good cavitation performance, and are suitable for situations where water levels become larger and head requirements are higher. The conveying medium is raw water or lightly polluted water, and the temperature of the transported liquid can reach 70 ℃.

Submersible shaft mixed flow electric pump flow rate: 200-36000m3/h, head 3-25m, voltage level: 380-10000V, power: 4-1250kW, speed: 245-3000r/min, efficiency: 60-70%.
