In various fields, our products find applications in large hotels, hospitals, schools, office buildings, supermarkets, commercial residences, subway stations, train stations, airports, various transportation tunnels, petrochemical plants, thermal power plants,oil storage tanks, large warehouses, industrial and mining enterprises, seawater injection, etc.

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.

Three start-up functions for diesel engines:
1. Manual start function: manual and automatic interlocking can be completed through the transfer switch, and the manual start function can be realized:

2. Automatic manual function: allow to start three times. If the startup fails for three times, it will issue a “startup failure alarm” and automatically exit the startup state. After a successful startup, the time from startup to rated load is 5-10-15S (depending on the unit capacity);

3. Emergency manual direct start function: When the automatic control device fails, the emergency manual direct start function can be realized.

The diesel engine pump set has the characteristics of good startability, strong overload capacity, compact structure, convenient maintenance, simple use and high degree of automation. It is a kind of fire fighting equipment with reliable performance.

Fire pumps are more expensive than ordinary water pumps because they must meet specific fire protection standards and are built to handle high temperature and pressure water. They also have additional features, such as larger motors, to rapidly provide the necessary flow rate to meet fire protection requirements.

XBC series diesel engine fire-fighting pump group is a new-style fire-fighting equipment (“equipment” thereafter) developed by this Co. in accordance with GB6245-98 “Performance Requirement and Testing Method of Fire-fighting Pumps” and NFPA20 “Installation of Centrifugal Fire-fighting Pumps” etc. standards and, upon the
fitted fire-fighting pumps (single-stage single-suction type, single-stage double-suction type and sectional multistage type), can be divided into XBC-IS, XBC-S and XBC-D three sub series. The equipment has a wide range of pressure and temperature and can be used for almost every occasion necessary for fire-fighting. The diesel engine fitted with the equipment is an excellent product domestic or imported, features good starting performance, strong overload capacity, compact structure, easy maintenance and use and high degree of automation. The equipment is really a fire-fighting one advanced and reliable in performance. The reasonable use and serious maintenance of the fire pump is the most important prerequisite for ensuring the normal and reliable operation of the pump, giving full play to the emergency function and prolonging the service life. In order to make the pump operator familiar with its structural characteristics, grasp the use and maintenance methods, and make good use of the pump, we have prepared this manual for the operator reference

Electric fire pumps are widely used in our production and life, such as in water treatment, fire safety and other departments. After the reform and opening up, it is widely used in life and production due to its characteristics of complete sealing, no leakage, and corrosion resistance.

The diesel engine fire pump is suitable for unmanned emergency water supply system. The product has the characteristics of good technology, high degree of automation, high performance and protection function, reasonable structure, easy installation, and high cost -effectiveness. Supplement the pressure of the network.

Key components include the pump itself, the engine or motor, an intake system, a discharge system, and various safety features such as pressure relief valves.

• Automatic switching between three pumps, when the electric fire pump fails, the diesel engine backup pump will automatically start
• Works even with power outages
• Adopt high-quality NSK bearing, wear-resistant mechanical seal or packing seal

Fire pumps are an important part of the fire protection system, especially in high rise structures.In basic 400 – 500 or advanced water situations, fire pumps are important to distribute water into water lines and sprinkler systems where the water pressure of the fire fighting equipment cannot reach. Especially in low-rise structures, fire pumps are important for fire control.
Stylistically, fire protection is a dangerous activity, but without a well-designed and professionally installed system and pump, it certainly becomes more dangerous and commercial assets and lives are less at risk.

The fire-fighting water provided by most fire-fighting water sources needs to be pressurized by fire-fighting water pumps to meet the requirements for water pressure and water volume during fire-fighting, which is an important part of fire-fighting. In daily use, we often encounter fire pumps vibrating or making abnormal noises. What is the problem?
1. The installation is not firm and the fasteners are loos

2. Wear between impeller and seal ring

3. Improper installation of pump body and pump shaft

4. Cavitation causes abnormal sound inside the pump

When the stabilized 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.

First, what’s a water pump? It’s a device used to transport liquid, pressurize the liquid, and make the liquid from the first liquid position to the high liquid position. The first water pump constructed by the Chinese is called” water windmill”. latterly, around 300 BC, the emergence of the” Archimedes screw pump” is more analogous to ultramodern pumps. In addition, the following introductory knowledge points are what you must understand.
1. Centrifugal pump

Centrifugal pump is the most common type of pump. In simple terms, the working principle of centrifugal pump is to rotate the impeller to drive the liquid under the action of centrifugal force. The liquid leaves the impeller and enters the volute. As the inflow passage of the volute gradationally expands, the fluid haste slows down, and the pressure rises continuously, and eventually it’s discharged through the conduit.
2. Impeller
The impeller is one of the main factors in the water pump, and it’s the core element that transmits mechanical energy to the liquid. The impeller is substantially divided into three types open type,semi-open type and closed type. The material conditions for the impeller are high, wear resistance is needed, and the manufacturing process is good.

3. Cavitation

Cavitation is the conformation of numerous bitsy recesses when the liquid connections the liquid under high- speed inflow and pressure, and gradationally expands into grottoes when serious, and cavitation frequently occurs in the impeller and pump covering.
