I.Preparation work before operation of magnetic pump.
1. Check whether the bolts and connectors are loose, and tighten if they are loose.
2. Use
the hand disc to move the coupling to make the pump rotor rotate
several times to see whether the rotation is flexible and whether there
is a sense of noise or uneven weight, so as to judge whether there is a
foreign body in the pump.
II. Start-up procedure of magnetic pump.
1. Open the suction valve, close the relief valve, pressure gauge valve, vacuum gauge valve, and pump.
2. Open the discharge valve slightly, start the motor, and check the motor steering (clockwise from the direction of the motor).
3. After turning correctly, start the motor and open the pressure gauge and vacuum gauge valve.
4. After
the pressure rises and thinks that the machine is running stably,
slowly open the discharge valve and the pump works normally.
5. Pump operating point should float up and down at the operating point, too small, too large flow are easy to cause pump damage.
III. Matters needing attention in the operation of magnetic pump.
1. No-load
operation of the pump is never allowed. Once the liquid is cut off or
there is friction in the pump, stop running and switch the pump to
prevent further damage caused by the pump no-load.
2. If
there is a medium that is easy to solidify in the pump, steam must be
passed before start-up, and only after the medium is fully dissolved can
you start the operation.
3. In
the trial operation of the magnetic pump, it is necessary to check
whether the whole system has air leakage, liquid leakage, performance
meets the requirements, whether the unit has large vibration and
abnormal noise, it can be put into operation only after it is considered
qualified in all aspects.
IV. maintenance and maintenance of magnetic pump.
The
magnetic pump must do a good job of daily maintenance and maintenance
in order to effectively give full play to the good performance of the
pump and prolong the service life of the pump. a. Monitoring and maintenance in operation.
During
the operation of the pump, it is necessary to strengthen the inspection
of the unit, find the anomaly as soon as possible and deal with it as
soon as possible. In general, during the inspection, we should pay attention to the following aspects at all times:
1. Pay attention to whether the sound and vibration of the unit are normal.
2. Observe whether the meter readings such as ammeter, power meter, pressure gauge, vacuum meter and flow meter are normal.
3. Pay attention to whether the pipeline is leaking gas, liquid, etc.
4. Usually keep the unit clean and pay attention to the safe operation.
V. Maintenance after operation.
1. In
the cold season, especially in the outdoor pump, the liquid in the pump
should be removed immediately after stopping to prevent freezing.
2. The general spare pump should also be started regularly.
3. Regular
maintenance of magnetic pump, check and replace unqualified vulnerable
parts, such as bearings, bushings, thrust rings, etc.
