Fire water pump refers to the water supply pump used to ensure the system pressure and water volume in the fire water supply system. The fire pump transfers energy to the water through the rotation of the impeller, thereby increasing the kinetic energy and pressure energy of the water, and transporting it to the fire extinguishing equipment to meet the water volume and water pressure requirements of various fire extinguishing equipment. Such as fire hydrant pumps, sprinkler pumps, fire transfer pumps, etc.

Pressure relief valves prevent over-pressurization in the fire pump system. They ensure safe operation by releasing excess pressure, protecting the pump and connected piping from damage.

DJ fire pump set is suitable for fire protection occasions such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas, textiles, ships, oil tankers, etc.

The diesel engine fire pump is usually used as a backup facility. It will only start automatically when the electric water pump fails or is powered off when the fire signal comes. When equipped with an ultra-low pressure pump starting device, the matching electric pump control cabinet should also be equipped with an ultra-low pressure pump starting device, and the lower limit of the pump should have a certain pressure difference. Of course, it is also possible to design a control system that is more suitable for customer needs according to customer requirements.

1. Electric fire pump: various end suction pumps and split pumps.
2. jockey pump: vertical, small flow, higher lift than electric or diesel pumps.
3. Control panel: Automatically control the water pump with overload and overcurrent protection.
4. Accessories: suction pipe, discharge pipe with flange, battery, gate valve, check valve, flexible expansion joint, pressure switch, pressure gauge, base, etc

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.
