Submersible mixed flow pump

Zhijiang Pump IndustryQHBComplete Range of Submersible Mixed Flow Pump Models

QHB mixed flow submersible pumps are the upgraded products of traditional pump-motor units. The motor driving the pump is a dry, fully enclosed submersible three-phase asynchronous motor, which allows the submersible pump to operate submerged in water for extended periods. Zhijiang Pump IndustryQHBSubmersible Mixed Flow Pumps possess a series of unparalleled advantages over traditional units.

(1) Since the motor and pump are integrated, on-site installation is convenient and fast, saving up to 95% of installation time compared to traditional units.

(2) As the motor operates submerged, it has excellent cooling conditions. The pump station remains free of high temperatures and low noise, allowing for the construction of underground pump stations that preserve the ground environment. This greatly simplifies the geotechnical and structural engineering of the pump station, reduces the installation area, and saves 30-40% on construction costs.

(3) The submersible motor adopts double or triple mechanical seals and auxiliary sealing structures, with F-class insulation rated for temperatures up to 155°C, and protection等级 of IP68. Additionally, the motor is equipped with devices to detect seal leakage, winding temperature, and bearing temperature rise.

(4) Detection signals are centrally反馈ed to the monitor in the electrical control cabinet, making operation convenient and易于 achieving automatic and remote control.

Zhijiang Pump IndustryQHBSubmersible Mixed Flow Pumps Main Uses and Operating Environment

QZB and QHB submersible pumps can be widely used in industrial and mining ships, urban water supply and drainage, agricultural irrigation and drainage, and power station water supply and drainage. QZB axial flow submersible pumps are suitable for low-head, high-flow scenarios, while QHB mixed flow submersible pumps offer high efficiency and excellent cavitation performance, making them ideal for situations with significant water level changes and relatively higher heads. These products transport介质 such as raw water or mildly polluted water, with a maximum liquid temperature of 50°C, a pH range of 4 to 10, a volumetric concentration of solids below 2%, and a介质 density less than 1.2×103kg/m3. Using these products is the most thorough solution to address motor flood protection issues in areas with significant water level fluctuations along rivers and lakes.

Zhijiang Pump IndustryQHBSubmersible Mixed Flow Pumps Structural Description

The structure of the submersible pump is shown in the figure below. The submersible motor is located above the pump, designed as a dry structure with F-class insulation, reliable mechanical and auxiliary seals, and equipped with leakage and internal winding and bearing temperature rise protection devices. It comes with a control cabinet for safe and reliable operation,广泛适应ing to water quality and environmental conditions, with adjustable blades and a wide operating range.

Viewed from the water inlet direction, the impeller rotates counterclockwise.

For motor power below 315KW, the voltage is 380V or 600V; for motor power above 315KW, the voltage is 6KV or 10KV.
