ISO 9001 submersible sewage pump for Municipal engineering /
QW type submersible non-clogging sewage pump structure description:
QW type submersible non-clogging sewage pump consists of two parts
of the motor and pump, the two separated by oil isolation chamber
and mechanical seal components, is a mechanical and electrical
integration products, motor and pump with the same axis (rotor) the
entire pump length Short, compact. Equipped with a variety of
protection devices, making the pump safe and reliable operation.
The main components of the role as follows:
Signal line 1: equipped with full water pump control cabinet, the
implementation of all-round protection of the pump, including
leakage, phase, short circuit, overheating, motor overload and
Motor Stator 8: Class B or Class F insulation.
Leakage probe 11: The component is installed in the oil chamber, when the mechanical seal is damaged, the water into the oil
chamber, the probe can send a signal from the control system to
protect the pump.
Mechanical seal 13: the use of double-channel series seal, the choice of new hard corrosion-resistant tungsten
carbide material, with a reliable seal, wear, long life and other
Impeller 17: impeller with a single channel or dual flow channel
structure, with a strong ability to pass through the large
materials and fiber waste, to reduce the clogging, winding failure.
Pump body 15: equipped with the impeller, making the pump with high
Seal ring 18: installed in the mouth of the pump body, when the
impeller due to operation leaving the mouth ring wear, replace the
seal ring to ensure the pump to the best efficiency.
QW type submersible without clogging sewage pump Product use:
QW type submersible non-clogging sewage pump for the factory
business serious pollution of wastewater discharge, residential
sewage sewage station, urban sewage treatment plant drainage
system, air defense system drainage station, water plant water
supply equipment, hospitals, hotels Sewage, municipal engineering
construction site, exploration, mine supporting machine, rural
biogas digesters, farmland irrigation and other industries,
conveyor belt particles of sewage, dirt, can also be used for water
and corrosive media.
QW type submersible non-clogging sewage pump use and precautions:
- QW type submersible non-clogging sewage pump should be carefully
checked before use, whether the cable is damaged, fasteners are
loose or fall off, the pump in the transport, storage, the
installation process with or without deformation or damage.
- Measure the same and relative insulation resistance of the pump
motor with 500V megger. The value should not be less than 2
megohms. Otherwise, the motor stator winding should be dried and
the drying temperature should not exceed 120 ℃.
- The series of sewage pump installed fixed and mobile two. When
using a fixed automatic installation, the chain should be inserted
into (from the pump outlet, the connection should be parallel to
the pump outlet) two hanging ring screws or lifting board up and
down lifting pump. Evenly slow down along the guide until it is
automatically coupled to the position. When using mobile
installation, the first hose sets, with a chain into the two rings
up and down lifting pump, pay attention to the cable can not be
used as a rope to avoid danger.
- QW (WQ) type submersible non-clogging sewage pump connected after
the rotation direction from the inlet as counterclockwise rotation,
if the pump reversal, just the cable in any two lines to adjust the
wiring position that can.
- QW (WQ) type submersible air-blocking sewage pump chassis ground
must be strictly in accordance with the relevant procedures
properly, in order to ensure the use of personal safety, in the
pump running, is strictly prohibited in the vicinity of the
installation, people do? Move, just in case the electric pump
- QW (WQ) type submersible non-clogging sewage pump in the absence of
special circumstances must be equipped with automatic pump control
cabinet, do not directly hang the grid or use the knife switch to
turn on the power to ensure the normal operation of the pump.
- The pump should not be long-term operation in the low-lift state
(generally use the head should not be less than 60% of the rated
head), it is best to control the use of the proposed range within
the lift to prevent the pump due to overload and burn the motor.
- No self-circulating cooling device pump is strictly prohibited the
whole surface of the long-term operation to prevent overheating
damage to the pump.
