Innovative Fire Pump System Design for Enhanced Safety in Industrial Parks and High-Rise Buildings

Diesel engine fire pumps can be widely used in environmental protection, water treatment and fire protection departments to transport various liquids by using their own advantages.

Fire pumps are mainly used for pressurized water delivery in firefighting system pipelines, and can also be used in industrial and urban water supply and drainage, high-rise building depressurized water delivery, long-distance water delivery, heating, bathrooms, boiler cold and warm water circulation pressurized air conditioning refrigeration system water delivery and equipment matching, etc.

This is a set of EDJ fire pump set, which consists of electric pump + diesel pump + jockey pump. The three pumps are automatically started and stopped. When the joceky pump detects that the electric pump cannot operate normally, the diesel engine pump will start automatically. Can also be used, the fire pump set is widely used in various emergency firefighting occasions.

A fire pump is a device that increases water pressure for fire protection systems, while a fire hydrant is an external water supply point for firefighters to connect hoses. Fire pumps are often used within buildings, while fire hydrants are located externally for access by firefighting teams.

Single stage centrifugal pump includes pump body, pump cover, motor with output shaft, pump shaft, bearing seat, impeller, mechanical seal and mechanical seal gland installed in the pump body, which are connected with the motor through extended elastic coupling. The rotation direction of the pump, viewed from the driving end, is clockwise. Wanfulong is characterized in that it also includes a clip on coupling arranged between the motor output shaft and the pump shaft, and a guide bearing installed on the bearing seat to assist in supporting the pump shaft; The wafer type coupling is rigidly connected with the motor output shaft and the pump shaft respectively, and a space distance is left between the motor output shaft and the pump shaft to facilitate the assembly and disassembly of the mechanical seal and the mechanical seal gland. When repairing or replacing the mechanical seal, it is not necessary to disassemble the motor and pump cover.

Yes, fire pumps can be integrated with water mist systems, providing a fine water spray for fire suppression. The combined system is effective in controlling and extinguishing fires, especially in enclosed spaces.

Maintaining a fire pump in the context of a mechanical seal can be critical for safety and performance in various industries. Misunderstandings during this maintenance process can lead to inefficiencies, failures, and safety hazards. Here are some common misunderstandings related to fire pump mechanical seal maintenance:

EDJ diesel engine fire pump is used for various fire hydrants and sprinkler fire main pumps; it is suitable for various fire boosting and pressure stabilizing pumps; various villas, residential areas and other fire protection systems; industrial and civil building fire protection systems; suitable for Various oil depots, oil loading and unloading docks, logistics parks and other places with high fire protection requirements.

EDJ Multistage Fire Pump Set is electric fire pump+diesel fire pump+jockey pump.It can meet 120GPM~3000GPM with 100m~660m.

The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the voltage stabilizer pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.

There are numerous ways to maintain fire pumps and water pumps. The following styles are more effective. You can use them for reference
System 1 The installation of the pump set should be accurate and dependable, and there should be no egregious vibration duringoperation.However, or the bearing is hot to the touch( the temperature is advanced than 60 °C) and the water seepage in the seal of the pump shaft is further than 60 drops per nanosecond, the cause must be set up out and the fault should be excluded in time, If the pump makes abnormal noise when pumping water.
the
system 2 Screws that are squinched daily, similar as packing gland screws, irrigation entrapments,etc., should be disassembled with a suitable wrench and a reasonable necklace. You can put some slicking oil painting on it or wipe it regularly with an oil painting cloth to help rust; if the water drain screw isn’t used constantly, it’s easy to rust, so after buying a new water pump, you should first wind the water drain draw, and apply some machine oil painting and white lead oil painting on the screw thread, Change the new oil painting two or three times a time in the future.
the
System 3 If the pump is waxed with machine oil painting, the slicking oil painting should be replaced once a month; if it’s waxed with adulation, it should be replaced every six months. It should be noted that the water pump uses calcium- grounded grease, and the motor uses sodium- grounded grease, and they shouldn’t be used inaptly. Because sodium- grounded grease is hydrophilic, it’ll emulsify into froth and dissipate when it encounters water on the pump, while calcium- grounded grease is hysterical of high temperature, so it’s easy to melt when the temperature rises when used on a motor.

system 4 Don’t pump water with too important beach, so as to avoid unseasonable wear and tear of the impeller, mouth ring and shaft, and try to help water deficit operation. Running without water will damage the water seal, and the water pump is prone to water leakage or indeed no water.
System 5 After the irrigation and drainage season is over, the water pump should be precisely gutted and auditedimmediately.However, they should be repaired or replaced in time, and the corridor that should be waxed should be filled with suitable oil painting; Stylish stored in a dry place, If any damaged or misshaped corridor are set up to be unworkable.
