Main functional features of diesel-driven fire pump sets

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.

EDJ fire pump has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance. For conveying clean water or other liquids similar to water in physical and chemical properties.

DJ (diesel pump + jockey pump) Fire Pump Set
DJ Fire Pump Set The fire pump set consists of a pump connected to the diesel engine, pressure jockey pump, pressure vessel, controller for manual or automatic operation of the system and standard accessories mounted on the base. The fire pump system can be customized for different uses, such as high-rise buildings, facilities, hospitals, supermarkets, shopping malls, villas, apartments, etc.

A fire pump is part of the water supply for a fire sprinkler system and is powered by electricity, diesel or steam. It uses water from an external source to increase water flow and pressure. The pump inlet is either connected to a public groundwater supply line or to a static water source. The pump provides higher pressure water flow to the sprinkler system risers and hose risers. Fire pumps must be tested monthly and annually to ensure they are operating as designed. These two different tests are called the monthly “churn” test and the annual flow test.

These are pictures of a stock outdoor fire pump set. It is composed of electric pump, diesel engine pump, jockey pump, and accessories.

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 lifespan of a fire pump motor or engine varies based on factors like usage, maintenance, and the quality of the equipment. However, they are typically designed to be durable and long-lasting.

Fire pump room design is vital for system functionality, accessibility, and safety. This article delves into the key considerations when designing a fire pump room, such as space requirements, ventilation, and fire suppression. It emphasizes the importance of a well-designed pump room to ensure optimal pump performance and personnel safety.

1. Make sure all valves are open and the system is in good working order.

2. Check the fuel filter for any debris, and replace as needed.

3. Adjust the governor control to reduce the RPM of the engine, and limit fuel consumption.

4. Regularly inspect, clean and replace the air filter to ensure maximum efficiency.

5. Maintain the fuel injection system to minimize fuel wastage.

6. Use synthetic oil instead of petroleum-based engine oil.

Electric pump + diesel pump + joceky 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.

The fire pump is actually a pump that needs to be used in fire protection. According to different classification methods, it can be divided into different types of pumps. With its characteristics of full sealing, no leakage and corrosion resistance, it is widely used in environmental protection, water treatment, fire protection and other departments to pump various liquids. The pump types of the system are similar, but the head and flow are different. The selection basis of the fire pump should be considered from five aspects according to the technological process and water supply and drainage requirements. Fire truck fire pumps are used in fire protection, water treatment, environmental protection and other departments to pump various liquids.

The EJ (Electric pump + Jockey pump) Dual Power Fire Pump System is an innovative and reliable fire protection solution. Combining an electric pump for robust water pressure and flow with a top-quality jockey pump for stable pressure maintenance, this system ensures efficient and timely water supply during fires. With advanced automation, remote monitoring, and energy-saving features, the EJ Dual Power Fire Pump System is a trusted choice for commercial, industrial, and residential applications.

XBC diesel engine fire pump set is the latest according to the national standard GB6245-2006 “fire pump performance requirements and test methods”. This series of products has a wide range of lift and flow, and can fully meet the fire water supply in various occasions such as warehouses, docks, airports, petrochemicals, power plants, liquefied gas stations, textiles and other industrial and mining enterprises.

The two main starting and control methods for fire pumps are manual starting and automatic starting.

Manual Starting: Manual starting is the simplest and most commonly used method for starting a fire pump. It involves the use of a manual start switch or lever to start the pump motor.

Automatic Starting: Automatic starting is the most reliable method for starting a fire pump. It involves the use of a control panel, which can be programmed to start the pump motor when a drop in pressure is detected. The control panel also monitors the pump’s performance and can be used to shut off the pump if it fails to start or is not performing properly.

The pump casing of the electric pump of the fire pump set can be made of cast iron or stainless steel, the impeller can be made of copper impeller, the flow head, pressure or other parameters of the diesel pump are the same as those of the electric pump, and the diesel engine is connected to the pump head through a coupling. The jockey pump is a vertical pump, and its technical parameters are different from those of electric or diesel pumps. Generally, the lift is higher than that of electric and diesel pumps, and can be customized.

The electric fire pump is an important part of the fire water supply system. The electric fire pump consists of two parts, the motor and the pump. The pump and the motor are coaxial. The pump structure includes pump body, impeller, pump cover, mechanical seal and other components.

Fire pumps are critical components of fire protection systems, and their reliable operation is essential for effective fire suppression. However, like any mechanical equipment, fire pumps can experience various issues over time. Some common problems associated with fire pumps include:
