1.Regularly check the pump and motor, the replacement of wearing parts.
2.Always pay attention to the bearing box filling high quality calcium base grease, in order to ensure good lubrication of the bearing.
3.Do not use a long time ", in addition to pump corrosive liquid on the net, we should pay more attention to cleaning the various components and the pump flow within the clean, and cut off the power.
4.The pump is strictly prohibited no-load operation.
5.Such as containing solid particles in the medium, should be added at the pump inlet filter
Pipeline centrifugal pump in the use of frequency control cabinet must pay attention to the case:
Variable frequency pump (Group) design of water supply flow should be guaranteed to meet the requirements of the maximum design second flow of water supply system. The power supply shall be reliable (double power or double loop power supply); pump operating point should be selected in the pump characteristic curve (Q-H curve), the work area, and shall not be selected in the Q-H curve of the extension line, design the most unfavorable work point should be right at the end of the characteristic curve of water pump, pump out the water section, i.e., maximum while the head is low but it can meet the requirements, it is low and the pipeline characteristic curve of pump characteristic curve, the intersection area. The working range of the pump can be as far as possible in the high efficiency section of the pump; the speed regulation range should be between 100% ~ 25% of the water supply of the water pump; the equipment should have the automatic control function of the water level.
