As a fixed fire-fighting equipment, the diesel engine fire-fighting pump set has been widely used in fire-fighting diversion, especially for fire-fighting water supply in unexpected situations such as no power supply or abnormal power supply (mains power).

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.

There are many types of fire-fighting equipment, fire hydrants and fire extinguishers are a common category, and there is also a category of fire pumps, which can be described as the heart of the fire-fighting system and play an important role in pressurising the water supply for the fire-fighting system. Among the many fire pump products, fire pumps can be divided into multi-stage and single-stage fire pumps.

Multi-stage pumps have high efficiency, corrosion resistance, reliable operation and other properties, strong bearing capacity of the pump body, strong resistance to overload and more sensitive start. Ltd. introduces you to the relevant features of multi-stage pumps. First of all, Shanghai Xizhiquan multi-stage pumps have a compact structure, with small spacing between parts and small volume. The equipment runs smoothly, has a long service life and produces less vibration during operation, so the practical life of the equipment is correspondingly long.

With its unique structure, the direction of the water inlet and outlet can be adjusted according to different needs, so it is suitable for various place environments. The direction of the inlet and outlet is horizontal, which reduces the number of bends in the pipeline connection, thus simplifying the pipeline connection and greatly enhancing the efficiency of the fire fighting system.

The efficient operation of the multistage pump is used in many larger, more demanding fire-fighting locations. Its role is mainly to play a role in the fire fighting pipeline system to pressurise and send water, multi-stage pumps are not only suitable for all kinds of fire fighting systems, but also for industrial drainage, high-rise building water pressure supply, long-distance water delivery, water circulation pressure and other occasions.

Proper design and installation of suction and discharge piping are vital for the efficient operation of a fire pump system. The suction piping connects the fire pump to the water supply source, while the discharge piping carries water from the pump to the fire protection devices.

Key considerations for these piping systems include the sizing, material selection, and routing. Proper sizing ensures that water can be drawn from the source at the required rate, and the piping material must be compatible with the water and the environment. Piping routing should minimize friction losses and ensure that the system operates without cavitation or other issues.

Fire pressurized and stabilized water supply equipment can make the fire water supply pipeline system the most unfavorable point always maintain the fire pressure, and the use of air pressure water tank always stored in the 30 seconds of fire water, to ensure the fire pump before the operation of the fire spray water; The device uses the operating pressure set by the air pressure water tank to control the operating condition of the pump and achieve the function of pressurization and pressure stabilization.
