All places need to be equipped with fire-fighting facilities, and fire pumps are necessary water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between the two is The electric fire pump needs to be supplied by the power system. If the power is cut off, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

This equipment is an EEJ fire pump set customized by a Greek customer with a frequency of 50Hz. The electric pump adopts an XA pump.This pump combines the advantages of similar products in China and abroad, and is designed with excellent hydraulic model.

1. Water filling treatment Before selecting the power-on power, make sure that the fire pump should be filled with water when it is turned off, and the suction should be increased to make the pressure difference larger and quickly clean up some acid-base reagents and other pollutants. Make sure to fill the water well.

2. Selection of electrified power The horsepower of the fire pump will be selected according to the size of the pump. Before electrifying the pump, carefully check the electrical power. Once the power is not grasped accurately, it is easy to cause insufficient suction. Therefore, in order to make it have sufficient suction, the power should be selected reasonably. If there is no electricity, the fire pump cannot be started, let alone used. But does it mean that the pump can be used as long as there is electricity? Not necessarily, the pump can only be used if the electrified power is reasonable and the voltage is within the normal range.

Fire pumps have a wide range of uses. In addition to providing water for fire-fighting piping systems, they can also be used for industrial water delivery. Fire pumps can also be used for water supply and drainage systems in cities. There are also other relatively long-distance water delivery tasks, such as heating boilers, hot and cold water circulation pressurization of bathroom boilers and multi-stage fire pump furnaces, etc., can all be completed by means of fire pump systems.

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.

The fire-fighting dual-power water supply equipment is suitable for all kinds of emergency backup pumps. When the mains is normal, the electric pump set is put into work.
