A multistage pump refers to a pump with two or more impellers, which can absorb and press water in stages and multiple stages, so as to lift the water to a high position, and the lift can be increased or decreased according to the needs of the pump impeller. The multistage pump can be equipped with a four-stage motor by increasing the number of impellers when the single-stage pump head needs to be equipped with a two-stage motor, which can improve the service life of the pump and reduce the noise of the unit. It is placed flat on the ground, with better stability, large flow and head, and wider application.

Signs include unusual noises or vibrations, reduced water pressure or flow, frequent tripping of the pump, leakage, and failure to start. Regular inspections and testing can help identify issues before they become critical.

Fire pumps are often required to have backup power sources, such as diesel generators or uninterruptible power supplies (UPS), to ensure they function during power outages.

The dual power fire pump is composed of a fire water pump, a double shaft extension motor and a diesel engine. One end of the output shaft of the double shaft extension motor is connected with the input shaft of the fire pump, and the other end of the output shaft of the double shaft extension motor is One end of a clutch is connected, and the other end of the clutch is connected with the output shaft of the diesel engine. The fire water pump, the double-shaft extension motor, the clutch and the diesel engine are all fixed on the base. The double shaft extension motor, the clutch and the diesel engine are respectively electrically connected with a control circuit through an action drive circuit. With dual-power fire pumps, there is no need to configure a second fire pump, which reduces floor space and saves manufacturing costs.

In the event of power outages or electrical failures, the diesel engine pump seamlessly takes over, guaranteeing continuous operation of the fire protection system. This dual-power configuration offers both reliability and flexibility, providing comprehensive coverage for fire safety needs.

The pump will start to work when the pressure in the fire extinguishing system pipeline of EDJ small Fire Fighting water supply equipment drops suddenly. The first triggered pump is the jockey pump(pressure stabili-zation pump). The pressure stabilization pipeline of the jockey pump is allowed to start frequently within a certain range. In general, the pressure of the jockey pump is 1-1.5 bar higher than that of the main pump.

Discuss the applicability of fire pumps in residential buildings, particularly high-rise or large complexes where water pressure may be insufficient for fire suppression. Explain what factors make fire pumps necessary in certain residential scenarios, such as building height and local fire code requirements, and outline how they can be adapted for residential use, ensuring safety without excessive water pressure.

First, what’s a water pump? It’s a device used to transport liquid, pressurize the liquid, and make the liquid from the first liquid position to the high liquid position. The first water pump constructed by the Chinese is called” water windmill”. latterly, around 300 BC, the emergence of the” Archimedes screw pump” is more analogous to ultramodern pumps. In addition, the following introductory knowledge points are what you must understand.
1. Centrifugal pump

Centrifugal pump is the most common type of pump. In simple terms, the working principle of centrifugal pump is to rotate the impeller to drive the liquid under the action of centrifugal force. The liquid leaves the impeller and enters the volute. As the inflow passage of the volute gradationally expands, the fluid haste slows down, and the pressure rises continuously, and eventually it’s discharged through the conduit.
2. Impeller
The impeller is one of the main factors in the water pump, and it’s the core element that transmits mechanical energy to the liquid. The impeller is substantially divided into three types open type,semi-open type and closed type. The material conditions for the impeller are high, wear resistance is needed, and the manufacturing process is good.

3. Cavitation

Cavitation is the conformation of numerous bitsy recesses when the liquid connections the liquid under high- speed inflow and pressure, and gradationally expands into grottoes when serious, and cavitation frequently occurs in the impeller and pump covering.

Problem one lower water or no water
1, electric pump reversal will lead to the pump doesn’t produce water.
2, the pump can’t normal water into the same can’t be water, check whether the water bay or check stopcock is blocked or stuck, pumping pipe if there’s a leak will also affect the water into the water.
3, the pump internal corridor of the wear and tear or connection out, check the pump and motor coupling wear and tear, loose and impeller is worn.

Problem two ：
1 、 Check the power force as described over, including connectors, switches, fuses,etc.
2. Check whether the impeller in the pump is jammed by foreign objects
3. A burnt motor will also affect the launch of the pump.

Problem three the water affair is big for a while and small for a while
1. still, the lack of depth down the well may beget this problem, If the pump is a submersible pump.
2. The inflow rate of the pump is too high and needs to be replaced with a suitable pump.
