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.

Fire pumps are typically started automatically when the fire sprinkler system detects a pressure drop caused by the activation of one or more sprinklers. This automatic start is usually controlled by a pressure switch or controller.

This is a set of EDJ fire pump set, which consists of electric pump + diesel pump + jockey 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.

Fire pump installations must consider factors such as temperature, humidity, and potential flooding. Pumps should be installed in environments that protect them from extreme conditions to ensure reliable operation.

The EDJ fire pump group is composed of electric pump + diesel pump + jockey pump. The three pumps are automatically started and stopped. 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.

Diesel engine with mechanical emergency fire pump has the advantages of light weight, small size, flexible movement, quick start, fast water discharge time, large fuel tank capacity, corrosion resistance, reliable use, and convenient maintenance. Where batteries are allowed to be used, the unit can be installed and used with a battery starting device. The diesel engine is vertical, multi-cylinder, four-stroke, water-cooled. It can also be matched according to the requirements of air cooling.

What is a jockey pump? While its name may remind you of one of those little guys that tells a race horse where to go, a jockey pump is actually used to maintain a high pressure in a fire suppression system.

In the daily maintenance of the fire pump, we need to meet the following requirements: we need to ensure that the water inlet and outlet pipes, the various components of the controller, and the diesel engine system can work normally, and ensure that the power part is firmly connected to the water pump. We also need to check the opening status of the pump room, fire pump system, and various valves to ensure that the pump room has good heat dissipation conditions and that the components of the pump are in normal working condition.

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

Learn about fire pump fuel tank sizing, NFPA 20 requirements, and best practices for maintenance.

The diesel engine fire pump is usually used as a backup facility. It will only start automatically when the electric water pump fails or is powered off when the fire signal comes. When equipped with an ultra-low pressure pump starting device, the matching electric pump control cabinet should also be equipped with an ultra-low pressure pump starting device, and the lower limit of the pump should have a certain pressure difference. Of course, it is also possible to design a control system that is more suitable for customer needs according to customer requirements.

In cold climates, jockey pumps must be designed and installed with specific considerations to prevent freezing and ensure reliable operation. This includes using heat tracing or insulation on piping and pump components exposed to low temperatures to prevent ice formation that could block water flow. Jockey pumps may also be housed in heated enclosures or indoor pump rooms to maintain a consistent temperature around the equipment. Additionally, the selection of antifreeze solutions or special materials resistant to cold temperatures can help protect the pump from damage. Regular monitoring and maintenance are also essential to ensure that the jockey pump remains operational and that the fire protection system is always ready to respond, even in harsh winter conditions.

The electric fire pump unit is mainly used for fire hydrant fire extinguishing, automatic sprinkler fire extinguishing and other fire extinguishing systems of industrial and mining enterprises, engineering construction, high-rise buildings and other fixed fire extinguishing systems.
