The importance of diesel engine fire pumps under powerless conditions

The self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming capacity. There is no need to install a bottom valve in the pipeline. Before operation, it is only necessary to ensure that there is a certain amount of liquid in the pump. Self priming pumps of different materials can be used for different liquids.

The working principle of self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before starting the pump. After startup, the high-speed rotation of the impeller causes the water in the impeller channel to flow to the volute. At this time, a vacuum is formed at the inlet to open the inlet check valve. The air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.

The diesel engine fire pump has a wide range of lift and flow, which 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.

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 sets are mainly suitable for fire water supply and foam fire extinguishing systems in petrochemical, natural gas, power generation, cotton and linen textiles, warehouses, airports, docks, high-rise buildings and other industries. It can also be used in occasions such as water ships, offshore oil tankers and fire fighting ships. The unit adopts imported diesel engine and fire pump. It has the characteristics of quick start, reliable water diversion, reasonable power reserve, stable operation, high degree of “three modernizations”, wide range of pressure and flow, etc. It is an advanced and reliable fire-fighting equipment.
Rational use and careful maintenance of the pump set is an important prerequisite to ensure the normal and reliable operation of the pump set, give full play to the emergency function and prolong the service life. In order to make the pump set operators familiar with its structural features, master the use and maintenance methods, and make good use of the pump set, we have compiled this manual for the reference of the set operators.

The diesel engine fire pump set has three perfect starting functions:
​​
1. Manual start function: manual and automatic interlocking can be completed through the changeover switch, and the manual start function can be realized:
​​
2. Automatic manual function: three starts are allowed. If the three starts are unsuccessful, a “start failure alarm” will be issued and the starting state will be automatically exited; after one successful start, the time from starting to rated load is 5-10-15S (depending on the capacity of the unit). );
​​
3. Emergency manual direct start function: when the automatic control device fails, the emergency manual direct start function can be realized.

This diesel fire pump adopts OTS pump, which has large flow and fast speed. The diesel engine fire pump has automatic, manual and fault self-checking functions. It can monitor the working status of the whole process, restore the function of failure start, automatic pre-lubrication and automatic restart of preheating, so that the equipment start-up is safer and more reliable.

The XBC-S Diesel Engine Fire Pump is an essential equipment in firefighting systems, designed to meet emergency firefighting needs.

Diesel engine-driven fire pumps are designed and manufactured in accordance with GB “Fire Pumps”. Comply with CCCF certification requirements. The advantage of its product is that when a fire occurs, the power supply fails, and the electric fire pump set cannot be put into use normally, the diesel engine fire pump set can be put into operation automatically to ensure the normal fire fighting. Compared with the electric fire pump set, the second advantage is that it does not need long-term investment in power supply, saving the mains power supply transformer and normal expenses. Diesel engine fire pumps are equipped with various automatic functions to meet customer requirements, ensure long-term normal standby status of the equipment, and put it into fire fighting work at any time. The diesel engine fire pump set is also suitable for various emergency backup pump occasions.

The XBC-ISO Diesel Engine Fire Pump Set is an efficient and reliable firefighting equipment that combines the power of a robust diesel engine with the advantages of an ISO single-stage centrifugal pump.

The XBC-ISO pump set is suitable for emergency firefighting scenarios, particularly ideal for high-rise water supply, building firefighting, central air conditioning water circulation, industrial process system circulation, cooling systems, boiler water supply, industrial water supply and drainage, water plant supply, irrigation in plantations, and more. This firefighting pump set is equipped for emergency rescues and can operate efficiently even during power outages. Moreover, its end-suction design simplifies operation and saves installation time.

The biggest difference between the diesel engine fire pump and the electric water pump is that it has its own independent power supply system – the storage battery. Therefore, the start and operation of the diesel engine fire pump can be completely separated from the mains.
The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference. Of course, we can also design a control system that is more suitable for customer needs according to customer requirements.

XBD, XBC electric fire pump units and diesel engine fire pump units meet the national standards GB6245-1998 “Fire Pump Performance Requirements and Test Methods”, GB/T1147-1987 “General Technical Conditions for Internal Combustion Engines”. They can be equipped with ISG, IS, S, D and other pump types respectively, forming various structural types such as pipeline type, vertical multi-stage, horizontal single-stage cantilever type, horizontal split, horizontal multi-stage, etc., to be suitable for various working conditions Use under different conditions (different power, different speed, different materials, etc.).

XBD and XBC units are mainly suitable for fire protection engineering of steel, metallurgy, electric power, petroleum, chemical industry, construction, port and other operations, emergency water supply for blast furnace, continuous casting, converter and other accidents, power plant emergency water supply for power failure, nuclear reactor safety protection cooling water supply, And other water supply projects that require automatic control.

As environmental concerns become more prominent, there is growing interest in environmentally friendly firefighting pump options. This includes pumps that use biofuels or alternative energy sources such as solar power, as well as pumps designed to minimize emissions and reduce environmental impact during operation.

XBD 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, bathroom, boiler cold and warm water circulation pressurized air-conditioning refrigeration system water delivery and equipment matching, etc. occasion.

The diesel engine fire pump unit is directly driven by the diesel engine fire pump, and it is a mechatronic equipment that can start and complete the water supply in a short time. The diesel engine pump set is driven by a diesel engine without external power supply. Diesel pumps are suitable for fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, and textiles. Especially when there is no electricity and the grid is not satisfied, choosing a diesel engine-driven water pump is the safest choice.
