Correctly select the supporting motor that matches the performance parameters of the pump to prevent the motor from being too small and overloaded for a long time; before starting the pump, check whether the outlet valve is fully closed to prevent the motor from being burned due to excessive starting current; The technical parameters of the motor require maintenance, check the power supply voltage and the current of each phase, and ensure that the error is within the allowable range.

1. The weight of the pipeline should not be borne on the pump, otherwise the pump will be easily damaged.

　　2. The pump and motor are of integral structure. The pump and the motor are an integral structure. It is calibrated by the manufacturer at the time of shipment, so there is no need to adjust the contract when installing it. This makes installation very easy.

　　3. The foot bolt must be tightened during installation. The pump should be inspected at regular intervals to prevent it from loosening. To prevent the pump from vibrating violently when starting up and affecting the performance of the pump.

　　4. Before installing the pump, check carefully whether there are any hard objects (such as stones, iron sand, etc.) in the flow channel of the pump that may affect the operation of the pump, so as to avoid damaging the overflow parts when the pump is in operation.

　　5. For easy maintenance and safety in use. Install a regulating valve on the pump’s throttle and a pressure gauge near the pump’s throttle, and for high head pumps. To prevent water hammer. A check valve should also be installed in front of the outlet gate valve to cope with sudden power failure and other loss of power accidents, thus ensuring that the pump operates under suitable working conditions and increasing the service life of the pump.

　　6. The pump is used in suction range situations. It should be equipped with a bottom valve, and the pipeline should not have too many bends in the mouth of the flume, and there should be no water leakage or air leakage in the same inch. To avoid affecting the suction performance of the pump.

　　7, in order not to make impurities burst into the pump and block the flow channel to affect the performance. A filter should be installed in front of the pump’s flume.

　　8, the installation of pipeline bary for the rotation of the pump rotor parts, should be no grinding sound or jamming phenomenon, otherwise the pump should be disassembled to check the reasons.

The pressure stabilizer pump is a kind of fire pump. It is used to stabilize the pressure of the automatic sprinkler system and the fire hydrant water supply system, so that the water pressure of the system is always in the required pressure state. Once the sprinkler or fire hydrant comes out, it can flow out to meet the needs of fire fighting water volume and water pressure.

The fire pump should be installed firmly, and its firmness should be checked regularly, especially the anchor bolts or backrest bolts, to prevent the fasteners from loosening;

Strengthen monitoring by monitoring the vibration waveform of the pump during operation, regularly check and repair the wear between the impeller and the sealing ring, and discover and eliminate hidden dangers in time; when the vibration of the pump is found to be abnormal after starting, it should be decisively analyzed for cavitation phenomenon, whether the impeller is balanced, whether the pump shaft and the motor shaft are concentric or whether the shaft has been deformed, and then take corresponding measures.

Control and adjust the installation height of the pump so that the installation height between the suction port of the pump and the liquid surface does not exceed the maximum allowable installation height, especially for mobile fire pumps, if they cannot absorb and discharge liquid normally, the installation height may be inappropriate. It can be solved by reducing the installation height or reverse installation;

Or add a small-capacity storage tank in front of the pump to increase the height of the liquid level and increase the static pressure, thereby shortening the distance between the liquid level of the suction storage tank and the suction port of the pump to prevent cavitation;

It can also prevent cavitation by reducing the flow resistance loss on the pump suction line. Shorten the length of the suction pipeline as far as possible within the allowable range, reduce the number of pipe fittings such as elbows and valves, and appropriately increase the diameter of the suction pipeline;

By improving the strength and abrasion resistance of the pump material, it can also effectively reduce the erosion of the pump caused by cavitation, so as to reduce the damage caused by cavitation to the pump and prolong its service life. In the selection of the impeller, it is possible to choose high hardness and high elasticity materials with strong cavitation resistance.
