The vertical and dismantling pipeline centrifugal pump shaft and motor are rigidly connected by shaft coupling, which solves the problem of inconvenience for users to replace the wearing parts such as centrifugal pump bearings, mechanical seals and impeller. The outstanding structural design makes it easier to install and maintain.
One, vertical dismantling type pipe centrifugal pump installation:
1, the installation of pipe weight should not be added to the pump, should have their own support, so that the deformation of the pump can not affect the performance and life of the pump.
2, in order to maintain convenience and safety, install a regulating valve on the pump's inlet and outlet pipeline and install a pressure gauge near the pump outlet to ensure that it runs in the rated head and flow range and increases the service life of the pump.
3, the centrifugal pump for a suction occasions, should be equipped with bottom valve and inlet pipe should not be too many corners, and shall not have Water Leakage, leakage phenomenon.
4, after the installation of the pump shaft, the impeller should not have friction or card death, otherwise the pump should be removed to check the cause.
The installation of 5 and centrifugal pump can be divided into hard connection and flexible connection.
Two. Maintenance and maintenance of vertical dismantling pipe centrifugal pump: starch cyclone
A, maintenance and maintenance in operation
1. The inlet pipe must be highly sealed.
2. It is forbidden to run the pump for a long time under the condition of cavitation.
3. When the pump is running in large flow, the motor is overcurrent for a long time.
4. Regularly check the motor current value in the pump operation, and no more than the rated current of the motor.
5, the centrifugal pump should be supervised by a special person during the operation, so as to avoid accidents.
6, the centrifugal pump should be operated for 500 hours to refuel the bearing. The motor power is greater than 11KW with a refueling device, use the high pressure oil is injected directly into the gun, in order to ensure good bearing lubrication.
7, after long term operation of centrifugal pump, due to mechanical wear, the noise and vibration of the unit will increase. It should stop checking and replace the vulnerable parts and bearings if necessary. The overhaul period of the unit is usually one year.
B, maintenance and maintenance of mechanical seal
1, mechanical seal lubrication should clean no solid particles.
2. Strictly prohibit mechanical seals working in dry grinding.
3, before starting, the disk drive pump (motor) is a few circles, so as to avoid the sudden start of the seal ring fracture damage.
