Submersible pump product overview
QJ well submersible pump is a complete set of tools for extracting
groundwater from deep well, widely used in farmland irrigation,
industrial and mining enterprises for water supply and drainage,
plateau, mountain livestock water. QJR well with hot water
submersible pumps, using special materials and structures for the
extraction of underground hot water. In addition, the company
according to user needs to produce seawater, mines and other
special occasions with submersible pumps. The submersible pump host
consists of QJ submersible pump and YQS submersible pump. Submerged
underwater work, with a compact structure, small size, light
weight, installation, use, easy maintenance, safe and reliable
transportation, energy conservation and other advantages.

Characteristics of submersible pump
QJ submersible pump consists of the multi-stage centrifugal
impeller in series. The pump stage is connected by a flat rib or
bolts, each of which is supported by a rubber (or copper) bearing,
with no check valve at the top of the pump. YQS submersible motor
is a closed water-filled three-phase asynchronous motor, the
winding is made of the water-resistant continuous sealing
structure. Both the bearing and the thrust bearing are water
lubricated bearings. The upper part of the motor is equipped with
the sand control mechanism to prevent the sediment from entering
the motor internal control.
Complete sets of supply
- host: submersible pumps and submersible motors.
- pipeline: water pipes, elbow, rubber pad, installation plywood, and
- cable: cable and cable connector material.
- start and protect the device.
Submersible pump structure description
- QJ well submersible pump unit consists of: water pump, submersible
motor (including cable), water pipes and control switch composed of
- submersible pump Each stage of the baffle is equipped with a rubber
bearing; impeller with a conical sleeve fixed on the pump shaft;
diversion shell with threads or bolts into one.
- high-lift submersible pump equipped with a check valve, to avoid
downtime caused by damage to the unit.
- submersible motor shaft with a labyrinth sandstand and two reverse
assembly of the skeleton oil seal, to prevent the flow of sand into
- the submersible motor with water lubricated bearings, the lower
part of the rubber pressure regulating film, pressure regulating
spring, composed of surge chamber, adjust the pressure caused by
temperature changes; motor winding with polyethylene insulation,
nylon jacket durable consumer goods water, Cable connection by
QJ-type cable connector technology, the connector insulation off
scraping paint layer, were connected, welding firmly, with raw
rubber around a layer. And then wrapped with water-resistant
adhesive tape 2 to 3 layers, outside the package on the 2 to 3
layers of waterproof tape or glue with a layer of rubber tape (bike
belt) to prevent water seepage.
- the motor is sealed, the use of precision stop bolts, cable outlet
plus gasket for sealing.
- the motor has a water hole at the top, there is a vent hole, the
lower part of a water hole.
- the lower part of the motor with the upper and lower thrust
bearings, thrust bearings on the groove for cooling, and it is
grinding stainless steel thrust plate, with the pump up and down
Submersible pump use
QJ-type submersible pump is a motor and pump directly into the
water work of the water lifting equipment, it is suitable for
extraction from the deep wells of groundwater can also be used for
rivers, reservoirs, canals and other water lifting projects: mainly
for farmland irrigation and plateau mountain Human and animal
water, but also for cities, factories, railways, mines, site for
