Vertical easy to detach pipeline type centrifugal pump shaft and motor by coupling rigid connection, for the user to solve the replacement of centrifugal pump bearings, mechanical seal, impeller, such as wearing parts inconvenient problem, prominent structural design of the installation and maintenance more convenient.

One, vertical and open type pipeline centrifugal pump installation:

    1, when installing the weight of the pipeline should not be added to the water pump, should have their own supports so as not to pump deformation of the impact of performance and life expectancy.

    2, in order to facilitate the maintenance and use of safety, in the pump import and export pipeline installation of a control valve and a pressure gauge installed near the pump outlet, in order to ensure the running in rated head and flow range, an increase of the service life of the pump.

    3, centrifugal pump for suction occasions, should be equipped with bottom valve, and the inlet of the pipeline should not have too much bend, and shall not leakage, leakage phenomenon.

    4, after the installation of a pump shaft, impeller should not have friction sound or death card, otherwise the pump should be opened to check the reason.

    5, centrifugal pump installation is divided into two kinds of rigid connection and flexible connection.

    Two, vertical and open type pipeline centrifugal pump maintenance and maintenance: starch cyclone

    A, operation of the maintenance and maintenance

    1, the inlet pipe must be highly sealed.

    2, the prohibition of pump in the long run under the condition of cavitation.

    3, the prohibition of pump running at large flow, the long-term operation of the motor.

    4, check the motor current timing pumps shall not exceed the motor rated current value.

    5, the centrifugal pump in the operation process should be specially assigned to take care of, so as to avoid accident.

    6, 500 hours of the centrifugal pump to cope with the bearing to carry on. 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, centrifugal pump for long-term operation, due to mechanical wear, noise and vibration unit inch increases, it should stop checking, if necessary, replacement of wearing parts and bearings, machine overhaul period generally a year.

    B, mechanical seal maintenance and maintenance

    1, mechanical seal lubrication should be clean without solid particles.

    2, mechanical seal is strictly prohibited in the case of dry grinding.

    3, before the start of the pump (motor) a few laps, so as not to suddenly start causing damage to the sealing ring.
