After purchasing the
fluorine lined centrifugal pump, the knowledge about how to use the centrifugal
pump is relatively lacking, and it is easy to damage the centrifugal pump. So it
is necessary to know and master the knowledge about how to use centrifugal pump
correctly. When using a centrifugal pump, after the power is connected,
carefully observe the operation of the centrifugal pump. The water outlet should
be continuous and uniform, and the centrifugal pump can be used only when there
is no vibration and noise. In case of sudden shutdown during operation,
immediately disconnect the power supply and check the cause. The interval
between two starts of a centrifugal pump shall be limited to the return of all
the water in the pump. If it is started too early, the motor will be burned due
to excessive resistance and water hammer in the water pipe. In addition, if the
centrifugal pump is installed in the well, it should be noted that the flow of
the centrifugal pump should meet the normal water output of the well, otherwise
it will cause the empty machine to run and burn the motor.
Precautions for
installation and use of fluorine lined centrifugal pump
1. Before the
operation of the centrifugal pump, use a megger to check the insulation
resistance of the motor stator winding to the ground, which shall not be less
than 50 megohms at least;
2. When the voltage of the water pump exceeds ± 10%
of the rated voltage, the water pump shall not be started.
3. To ensure the
safety of use, the grounding wire in the four core cable must be reliably
grounded to prevent electric shock accidents.
4. When the centrifugal pump is
used, it should be lifted vertically, and it is not allowed to stand on the
ground vertically, let alone fall into the sludge. When the pump is out of use,
it should be cleaned and placed in a dry place, and pay attention to
antifreeze;
5. Check the running direction of the rotor. It should rotate
clockwise from top to bottom;
6. Outdoor switches or terminals shall be
provided with rain proof and moisture-proof measures. It is forbidden to touch
the switch when wet hands or bare feet to prevent electric shock;
7. When
moving the centrifugal pump, the power supply must be cut off, and people are
not allowed to contact the water source when the electric pump is running, so as
to prevent personal accidents caused by electric leakage;
8. It is strictly
forbidden to operate the motor in phase failure. If the fuse is found to be
blown, it should be checked before continuing to use. It is not allowed to
thicken the fuse arbitrarily;
9. When the centrifugal pump is running, it
should be managed by a specially assigned person. If abnormal phenomena are
found, it should be stopped immediately for inspection and
troubleshooting;
10. After the centrifugal pump operates normally for half a
year under the specified working medium conditions, the sealing condition of the
oil chamber should be checked. If the oil in the oil chamber is milky or there
is water precipitation, the mechanical oil and mechanical seal should be
replaced in time. The water pump used under bad working conditions should be
overhauled frequently;
11. The user should choose the appropriate flow head
according to the actual working conditions to achieve the use effect. It is
forbidden to use over flow, otherwise the motor will be overloaded if the flow
is too large and the head is too low.
