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.

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.

The fire pump refers to a clean water pump used for fire water supply, and a single pump that handles medium temperature below 80 degrees and is not corrosive. The pump set is the joint operation of multiple fire pumps to ensure the quantity and stability of the water supply. The electric motor fire pump group adopts multiple fire pumps powered by electric motors. The general fire water supply environment is equipped with one electric and one diesel fire pump as the reserve water pump to ensure sufficient emergency water consumption. The main components of the electric motor fire pump group are the motor and the pump body. The subdivision of the pump body is the pump casing, the impeller, the pump shaft, the bearing, the coupling, the sealing form, the lifting pipe, etc. The specific fire pump model is determined according to the environment and performance requirements. According to the material quotation required by the customer, accurate selection is beneficial to on-site use and reduces failure problems.

Safety precautions include proper training for operators, ensuring adequate ventilation when using gasoline or diesel-powered pumps, using appropriate personal protective equipment (PPE), and following manufacturer’s guidelines for operation and maintenance. It’s also important to have a clear understanding of local regulations and requirements for outdoor fire pump installations.

Fire pumps are necessary because municipal water supplies might not always provide sufficient water pressure to effectively fight fires in large buildings or areas. Fire pumps boost the water pressure to ensure proper coverage and firefighting capabilities.

XBD series fire pump set is mainly used for fire hydrant fire extinguishing system, automatic sprinkler fire extinguishing system, etc. in fixed fire fighting systems of various enterprises and institutions, engineering construction, high-rise buildings, etc. The chemical properties are similar to the medium of water, and it can also be used for fire protection, living, production, public water supply systems and buildings, municipal water supply and drainage, etc.

Fire Pump Packages
Fire pump package comprises a combination of electric motor driven pump, diesel engine driven and electric motor driven jockey pumps that supply for fire suppression systems.
Fire pump package is required to comply with Local Civil Defense Authority regulations and International Codes of Practice e.g. National Fire Protection Association (NFPA).

Types of pumps used for fire service include: end suction, horizontal split case, vertical split case, vertical inline and vertical turbines.

Diesel pumps can be combined with electric pumps, jockey pumps, etc. to form an automatic water fire-fighting water supply system, and can be linked with the fire control center.

When the pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set to start the motor to start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine to the rated speed . The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the pump set receives a signal that the pressure of the pipeline network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.
