Basic types and characteristics of diesel engine fire pumps

Self-priming fire pump is a mechatronics equipment researched and developed according to the provisions of my country’s fire regulations and the different requirements of various users. The product is innovative, advanced and practical. It simplifies the design of the pump room. The underground pump room can be changed to the ground, which is convenient for construction and saves investment; the outdoor pool can also be used to meet the requirements of use; the self-priming function can be used to make the fire pool deeper. To 3-6m, under the same effective volume, the land area occupied by the pool is much smaller than the original, which saves land, facilitates construction, reduces construction costs, and greatly saves investment; it can work under the condition of negative water level and meet the requirements in time. Fire protection requirements; the self-priming fire pump can discharge water in time to rescue and extinguish fires in time; it has a strict and reliable automatic circuit detection function, so that the unit is usually in a quasi-fire-fighting state.

The correct maintenance of the diesel engine fire pump, especially the preventive maintenance, is easy and economical maintenance, so it is the key to prolong the service life and reduce the cost of use. Daily maintenance can be carried out according to the following steps to check the amount of fuel in the fuel tank – check the amount of fuel stored in the fuel tank and add it as needed.

·UL Standard:
Flow：50-2000 GPM   
Head： 80-250 PSI 

·NON-UL  Standard:
Flow：50-5000GPM 
Head： 40-250 PSI 

All places need to be equipped with fire-fighting facilities, and fire pumps are the water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between them is that electric fire pumps require power systems. supply. In case of power failure, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

Diesel fire pumps, also known as booster pumps, are used to boost water pressure from sources that do not provide adequate water pressure for the sprinklers to operate to a given specification. A fire pump can be connected to a city water main, tank or reservoir/pond used for firefighting purposes.

Fire pump is a kind of water pump widely used in environmental protection, sewage treatment and fire fighting units. It is similar to the general pump, but its head and total flow are different. And the pump can also be divided into single-stage and multi-stage two forms according to the structure.

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in emergencies such as no power supply or abnormal power supply, other diesel engines can also be equipped as power engines according to the needs of users.

-UL Standard:
Flow：100-3000 GPM   
Head： 90-250 PSI 
– NON-UL Standard:
 Flow：100-10000GPM   
Head： 40-250 PSI 

Fire pump room installed with units should be as close as possible to the pool, the water intake pipeline of the water part should be as short as possible, and the elbows should be as few as possible to reduce the resistance of the water intake. And ensure that the unit space is spacious enough for the operation and maintenance of the unit. Pump house should have hoisting equipment and thermal insulation measures to ensure that the lowest temperature of pump house (> 5 Celsius) is prepared before the pump is installed, and that the foundation can bear the weight of the pump group.

It is also ideal for shopping malls, commercial complexes, office buildings, and high-end residential towers. Whatever the setting, the Diesel Single-stage Single-suction Fire Pump delivers dependable performance to safeguard lives and properties from fire risks.

Fire pumps are not always running; they typically start automatically when a drop in water pressure is detected in the fire protection system.

When the diesel engine fire pump unit receives an effective fire signal, if the power supply system of the diesel engine fire pump is powered off, loses phase or the electric pump cannot start normally, the diesel engine fire pump unit will automatically start to run. Once the power supply system returns to normal or the electric pump can operate normally, it can automatically switch to the electric pump.

Electric fire pumps are used in various water environments, not only to meet the general water supply but also to be a good helper for fire-fighting water. The electric motor fire pump is manufactured with good structure and workmanship. It has a wide range of performance, and is easy to use and operate for a long time. The electric fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

Diesel engine fire pumps are relatively common in life, and their performance requirements are relatively high. In normal use, more attention must be paid to maintenance to prolong the service life of the pump. Because diesel fire pumps are not omnipotent, there will be some problems in daily use, so when choosing equipment, we must pay attention to whether the quality of the equipment has reached the national standard. As fire equipment, all kinds of equipment must be Ensure performance, avoid affecting use in disasters and delay rescue.

The number of impellers is different, and the head is also different: Generally speaking, a single-stage pump has only one impeller, while a multi-stage pump has two or more impellers, which enables it to suck water many times and segment it. processing, which greatly increases the lift. Therefore, under the same medium flow, the lift of the multi-stage fire pump appears higher.
