The jockey 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. 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.

1, The fire pump in the installation, the pump bolt slack leakage
Treatment: adjust the front position of the fire pump, slowly tighten the screws of the outer ring of the pump body one by one, do not tighten one screw at a time
2、The sealing surface is not flat, the liquid in the pump will flow out to the pump along the place where the seal is not tight
Treatment: provide vertical multi-stage fire pump model parameters to replace the mechanical seal
3, Mechanical seal amplitude hair wear serious, seepage and water leakage occurred
Treatment: adjust the friction position of the seal ring, take out the seal ring, and then exchange the orientation equipment, such as the seal ring on the fastening spring loss of elasticity or cracking, can remove the spring, with the appropriate diameter of steel wire or wire tied
4、The fire pump body has sand holes or rupture
Treatment: Replace the pump body of the fire pump

answer:
1. Loss of rotation accuracy
2. Large rotation resistance
3. There is noise during operation.

answer:
1. Wrong installation direction
2. Loose or worn
3. Insufficient amount of lubricating oil, oil quality
4. Deformation of the oil throwing ring leads to failure to carry oil
5. Small axial clearance

There are many classification methods for fire pumps, which can be divided into sprinkler pumps, fire hydrant pumps, jockey pumps, etc. according to their uses.
jockey pump: The flow rate of the stabilizer pump is small. Usually, water is taken from the fire pool or high-level fire water tank and sent to the system to maintain the pressure in the system pipeline. When a fire occurs, the flow rate used to start the system is provided until the main fire pump is started. , the jockey pump needs to be set up as a backup pump.

A pipeline pump refers to a water pump that can be directly installed on a water pipeline, and can also be called a pipeline centrifugal pump. More space-saving compared to ground-mounted pumps. This pump is mainly used for industrial water transportation and urban water system. Model, different pump body materials can be selected in different transportation environments, and it is a very popular transportation equipment at present.

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.

1, impeller inflow channel blockage
First of all, the most intuitive problem, check whether the impeller is stuck in the main blockage, if so, timely cleaning can break theproblem.However, filtering bias can be added to the front of the pump bay to avoid the impeller runners being blocked again, If necessary.
2 、 Inside leakage
When the gap between the connection points of colorful corridor in the pump is too large, it’ll beget the pump to blunder, performing in a drop in discharge pressure. When this problem occurs, dismembering and form should be carried out.
3 、 Cavitation
still, performing in the pump bay pressure is lower than the impregnated brume pressure of the pumping medium, it’ll form cavitation, If the bay pipeline system has no blockage or the bay stopcock opening is too small. At this time, the blockage should be cleared or the bay stopcock should be opened wide, or the liquid position of the bay pool should be increased.
4 、 drop in rotational speed
Check whether the speed of the pump is reduced because of certain factors, the speed is commensurable to the head, if the speed of the problem, check the reasons, reasonable results.
5 、 Motor reversal
Observe the steering of the pump, if the steering is reversed, exchange the two cables on the outstations of the motor.

The fire-fighting booster and stabilizer pump must be kept in operation at ordinary times to maintain the pressure of the pipe network. In the event of a fire, it should still be able to run for a period of time until the main fire-fighting fire pump is started, and the stabilizer pump must be set according to the main and standby pumps. Since the stabilized pump needs to keep running all the time, and the stabilized pump needs to be in working state for a long time, it has high requirements on its service life.

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.

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.

Centrifugal fire pumps need to be manually filled with liquid before starting to clear the air accumulated in the pump casing. When filling the pump, ensure that the bottom valve of the suction line is well closed; For fire pumps, it is necessary to ensure that the automatic filling pump system works normally; regularly check the tightness of the suction pipeline to prevent the air from being sucked in due to poor sealing, and to avoid air binding during the operation of the pump and affect the work.

Starting with a cargo can beget damage to the motor, the factual use of head is too much lower than the pump nameplate head; submersible pumps without water work for too long.
First, first figure out whether the motor burn is burned comportments( mechanical failure) or burned coil( electrical failure).

still, substantially due toover-current, occasionally the voltage is too high or too low will also beget the coil to heat short circuit, If it’s the fault of burning the coil.
