product description:

Weihu QZB series submersible axial flow pump is a replacement product of the traditional water pump motor unit. The motor that drives the water pump is a dry fully enclosed submersible three-phase asynchronous motor. This type of submersible pump can be immersed in water for a long time. Has a series of unparalleled advantages of traditional units.

(1) Because the motor and the water pump are integrated, the installation on site is convenient and fast, which can save 95% of the installation time compared with traditional units.

(2) Since the motor runs under water, the motor has good cooling conditions, no high temperature in the pumping station, and low noise. The underground pumping station can be built to maintain the ground environment, greatly simplifying the geotechnical and building structural engineering of the pumping station, reducing the installation area, and saving engineering Cost 30-40%

(3) The submersible motor adopts double and triple mechanical seal and auxiliary seal structure, F-class temperature-resistant 155 ° C insulation, and IP68 protection grade. And in the motor, seal leakage, winding and bearing temperature rise detection devices are provided.

(4) The detection signals are fed back into the monitor of the electric control cabinet, which is easy to operate and easy to realize automatic control and remote control.


Conditions of Use:

QZB submersible electric pump can be widely used in industrial and mining ships, urban water supply and drainage, farmland drainage and irrigation, power station water supply and drainage. QZB axial-flow submersible electric pump is used for low-lift and high-flow applications. The transport medium is raw water or light sewage. The high temperature of the transport liquid is 50 ° C, the pH of the transport medium is 4-10, and the volume ratio of the transported medium is 2 % Or less, the density of the medium is less than 1.2 × 103kg / m3

Submersible axial flow pump parts materials and brands:

Pump body: HT250 or stainless steel 304/316

Pump shaft: 2Cr13, stainless steel, carbon steel

Submersible motor: 100% copper coil, cold rolled silicon steel sheet, high temperature dip paint

Bearings: foreign SKF, NSK, KOYO bearings :; domestic Luoyang, Wafangdian, Harbin bearings (can be selected according to customer needs)

Water parts: HT250, stainless steel


Structural characteristics and working principle:

Steel wellbore, embedded parts, floating box shutter, matching diving cable, starter control cabinet, horizontal bracket, elevator,

Booms, seal rings, “O” -shaped seals, auxiliary accessories for submersible axial flow pumps (including well cover devices,

Outlet device and accessories, anti-lifting device), embedded parts of submersible mixed flow pump (including pump base bracket assembly, embedded

Base plate, cover of embedded well), comprehensive protector for low-voltage motor, with RS485 output interface, etc.


Model meaning:

Wellbore installation: Supported by a specially made wellbore, the well pump holds the pump body and makes the pump potentially underwater, through a wall pipe or a riser pipe to the water outlet. Used in water conservancy projects and water stations.

The wellbore floor-mounted installation pump and wellbore are equipped with a base and placed on the bottom surface. This method requires a stable and stable bottom surface.

Open-type submersible axial flow pump is equipped with "V" type wellbore, suitable for pools and other places. The water level can be reached by the pump.

Cement wellbore installation: Same as wellbore installation, except that the former uses wellbore and the latter uses cement.

Horizontal installation: submersible axial flow pump + bracket dives underwater, the bracket plays a fixed role. Suitable for pool. Fish ponds and other occasions.

The oblique pull-type installation submersible axial flow pump + bracket + wellbore. Suitable for pools, rivers and other places.
