QW (WQ) type submersible non-clogging sewage pump structure
description:
QW (WQ) 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
other projects.
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 characteristics.
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
efficiency.
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 (WQ) type submersible without clogging sewage pump Product use:
QW (WQ) 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 (WQ) type submersible non-clogging sewage pump use and
precautions:
- QW (WQ) 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
leakage accident.
- 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.
QW (WQ) type submersible non-clogging sewage pump installation,
operation and maintenance:
- When installing and handling the pump, it is strictly forbidden to
make the cable, so as not to cause the cable inside break, the
connector is off-line, etc. The pump can not run normally, even
burn the motor;
- Make sure that the grounding cable of the pump cable is properly
grounded. When the pump is working, it is strictly forbidden to
close the working area or touch the pump. In order to reduce the
risk of electric shock, it can only be connected with the
appropriate grounding socket.
- Do not overload operation;
- The cable used with the pump can not be less than 1.2 times the
area of the pump cable;
- When installed, the pump must be fastened, but can not make the
cable force, or with the pump start and stop when a rotation;
- run-time found that the pump is not water, you should check whether
the pump is reversed, or pump outlet at the check valve inside the
air is not drained;
- Regular inspection of the pump motor phase or relative between the
insulation resistance, the value should not be less than 2MΩ, or
should be disassembled;
- Electric pump in the specified working conditions, the normal
operation after six months, should check the oil chamber sealing
situation, such as oil in the oil is emulsified or water
precipitation, should be replaced 10 # oil and mechanical seals;
- After a year of normal operation of the pump, it should be
overhauled, replace the wear parts that have been worn and check
the status of the fasteners. At the same time, replace the grease
to ensure that the pump is well lubricated during operation.
- If the pump is not in use, please clean it and dry it.
QW (WQ) type submersible non-clogging sewage pump repair and
maintenance:
- Pump should be hand management and use, and regularly check the
pump winding and the insulation resistance between the chassis is
normal.
- Each time, especially for thicker and thicker slurry, the pump
should be placed in the water for several minutes to prevent the
sediments left to ensure that the pump clean.
- If the pump is not used for a long time, the pump should be removed
from the water, do not immerse in water for a long time to reduce
the motor stator windings damp the opportunity to increase the life
of the pump.
- In the conventional state of each pump after the use of 3 00 ~ 500
hours after the filling or replacement of oil in the oil tank (10 ~
30 oil), so that the mechanical seal to maintain a good lubrication
state, improve the mechanical seal life.
- After the pump is removed and repaired, the cabinet assembly must
be inspected by 0.2MPa airtight test to ensure that the motor is
sealed and reliable.
- The seal ring between the impeller and the pump body has a sealing
function, such as sealing damage will directly affect the pump
performance, if necessary, should be replaced.
