Guzu Machinery GZT
series non-blocking self priming trash pump produced by our company introduces
the new technology and technology from the United States. This product
overcomes the shortcomings inherent in the traditional submersible sewage pump
and engine driven trash pump, and has the characteristics of novel structure
and reliable performance. Its battleship-style shape is the first in China; its
unique oil-lubricated mechanical seal structure, non-blocking blades,
replaceable liners, easy-to-maintain design and advanced BAUER devices make
this series the standard for a new generation of self priming sewage pump.
model. A very large vortex chamber plays an important role in the pump. It can
perform efficient draining operations without the need to install a check valve
on the inlet and outlet water pipes when the pump is fully operational. This
product can be widely used in municipal sewage. Industrial wastewater treatment
engineering and various wastewater grading and centralized treatment systems
for conveying liquids with mild corrosion or containing large amounts of solid
particles. The basic material of the pump is gray cast iron, and the impeller
is made of ductile iron.
GZT series wet prime
pump is divided into eight specifications from 50-350. The performance range
is:
The flow rate is
10-1500M3/H,
The head is 10-68m,
which can meet the various needs of users by cutting the outer diameter of the
impeller, changing the speed and the combination of pumps of different
specifications.
Safety considerations
1. Be aware of this manual before disassembling the
pump for inspection and maintenance. Check the temperature of the pump before
attempting to open any cover, plate or bolt. If the pump is overheated, try to
cool it. Do not remove it from the heat pump.
The lower cover, the
pipe joint and the accessories prevent the high pressure in the pump from
attempting to push the parts out and hurt the person, and then operate the pump
after cooling.
2. Because the company does not have any motor
materials, it can not control the performance of the motor. Please check the
motor accessories carefully before starting the machine.
3. 6 inch trash pump can only be used to transport
industrial wastewater, mud or slurry containing a lot of solid particles with
mild corrosion, and can not transport volatile, strong corrosion and flammable
media, otherwise it will be crisis equipment and the safety of person.
4. Do not close the valve for a long time, otherwise
it will damage the parts and cause internal fluid boiling, pressure rise, pump
body rupture or explosion serious consequences.
5. Use lifting equipment to lift and move the water
pump unit, and disconnect the inlet and outlet pipes before lifting.
6. A protective cover must be added to the outside of
the exposed rotating parts to cause injury.
7. Drain the liquid in the pump before performing maintenance
on the pump.
Run
l. Self-priming
GZT series pumps are
self-priming centrifugal pumps. It is strictly forbidden to start running in
the pump chamber without water! Water shortage is not only unable to
self-prime, but also destroys mechanical seals due to dry grinding, mechanical
seal work
The temperature must
not be higher than 80 °C. Water must be added to the pump body under the
following conditions:
1) before the first
use;
2) The pump has been
used for a long time;
3) The liquid in the
pump is evaporated.
The water injection
hole is located at the upper part of the body, and self-priming can be achieved
after the pump body is filled with clean water.
2. start
The correct direction
of rotation of the pump is counterclockwise rotation from the impeller inlet.
Once the performance is found to be out of the specified range, immediately
stop the inspection and turn to the opposite direction, then change the wiring
to correct it.
When checking the
steering, disconnect the coupling or pulley and check the motor separately to
see if the motor shaft or fan is turning correctly. Open the outlet run, start
the pump, indicate from the pressure
gauge or noise
The sound can judge
the self-priming condition. If the self-priming is not completed after 5
minutes, it is necessary to stop the air leak in the inlet pipe. After the
self-priming is completed, the small outlet valve is properly closed, and the
liquid is slowly filled.
The outlet line,
after the outlet line is completely filled, adjust the valve to the rated flow.
3. Give way
There must be no
leakage on each mating surface of the pump to ensure that all pipe joints and
accessories are tightly fitted to reduce volume loss.
4. temperature
The pump's maximum
allowable operating temperature is 80 °C. Long-term shut-off operation will
overheat the unit, which will lead to serious consequences. At this time, the
cooling should be stopped. To prevent the pump from bursting,
The front cover is
equipped with a pressure relief valve, and the pressure relief valve is
automatically opened when the pressure inside the pump reaches a certain
extreme value. Always check and clean the pressure relief valve with its outlet
facing down, after the pressure relief valve is actuated or every time
Repairs must be
replaced.
5. Filter
If the filter is
installed in the import and export, it should be inspected regularly and
cleaned in time. When the pumping liquid flow drops sharply or the pressure
gauge reads abnormally, the possibility of the net being blocked should be
considered. It is strictly forbidden to use imported
