Ensuring Reliability of Fire Systems: The Importance of DJ Dual-Power Fire Pump Sets

Diesel-driven trailer-mounted fire pumps are characterized by rapid deployment, efficient drainage, and stable water supply capabilities. They are suitable for flood control, emergency rescue, and firefighting, improving operational efficiency and safety in complex environments.

This fire fighting equipment is an important part of building fire protection system. Its
routine inspection and daily maintenance are very important for each dual-power. If the fire
pump or booster pressure stabilizer pump in the dual power system fails, the fire accident
will lead to great losses of buildings and so on. It is the responsibility of the enterprise to
ensure that all equipment is regularly maintained and inspected, including the maintenance
and maintenance of all fire fighting systems

The product is EJ fire pump set. The EJ fire pump set has one electric pump and one jockey pump. The electric pump in the picture is XA pump. XA series horizontal single-stage single-suction centrifugal pump is a new generation of energy saving, environment friendly horizontal centrifugal pump researched and developed by our company, which absorbs advanced technology of similar products abroad and adopts domestic general performance parameters of centrifugal pumps

The application of electric fire pumps is not only in fire protection systems, but a variety of fire pumps are gradually showing their superior strength in industrial production and urban construction. This includes the implementation and expansion of high-end technologies for industrial and urban water supply and drainage, and high-rise building underpressure water delivery.

High-efficiency horizontal split-type fire pumps are designed specifically for large-scale fire water supply systems. They have advantages such as large flow rate, high efficiency, stable operation, and convenient maintenance. They are widely used in industrial fire protection, commercial buildings, and large fire pump room systems to ensure stable and reliable fire water supply.

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.

Fire pump as the name implies, fire pump, according to different classification is divided into different kinds of it is fully sealed, no leakage, corrosion resistance, widely used in environmental protection, water treatment, fire departments, is used to pump all kinds of liquid equipment.

Fire pumps require regular maintenance to ensure their reliability. Maintenance tasks include routine inspections, lubrication, testing, and exercising the pump to prevent corrosion and ensure proper functionality.

The current use of fire pumps is still relatively important. As the name suggests, fire pumps are pumps used for fire protection. The fire pumps we use now are all imported from abroad. Its performance mainly includes three aspects, sealing, no leakage, and corrosion resistance. Because of the particularity of its use, its requirements are relatively strict in terms of material selection and production. Considering many aspects, the performance and technical conditions of the fire pump meet the requirements of the “Fire Pump Performance and Test Methods” standard.

High-efficiency electric fire pump combines energy saving and high flow, compact design, stable operation, and easy maintenance for reliable fire protection.

As the name suggests, fire pumps are used in fire protection. They are divided into different types according to different classification methods. They are fully sealed and leak-free. They are used in environmental protection, water treatment, fire protection and other departments to pump various liquids. They are created The ideal pumps for non-leakage, civilized workshops and civilized factories are similar to the pumps for fire protection systems, but the head and flow are different.

The diesel engine (can be equipped with a clutch) is combined with the fire pump through a highly elastic coupling to form a fire pump unit. The unit also includes diesel tanks, cooling water tanks, fans, control panels (for automatic units) and other components.
When the unit is automatically controlled, the split or diesel engine automatic control cabinet (programmable) realizes the automatic start, input, and automatic switching of the system (switching from the electric pump group to the diesel engine pump group or from this group of diesel engine pump groups to another group of diesel engines) pump set), automatic protection (diesel engine overspeed, low oil pressure, high water temperature, three start failures, low oil level, low battery voltage and other alarm shutdown protection) and other functions, and can also interface with the user’s fire center or automatic fire alarm device, Realize remote monitoring.
