Safety Valve plays a safety protection role in the system. When the system pressure exceeds the prescribed value, the safety valve opens, and a part of the gas/fluid in the system is discharged into the atmosphere/pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to excessive pressure.
Pressure Tank: Water is a non-compressible medium. Generally speaking, the pressure drop of fire-fighting pipe network is normal. However, the pressure drop is very slow, the total loss of water in the pipe network isnot large, and the frequent change of pressure in the pipe network leads to frequent start-up and shutdown of pumps. Especially when the power of equipment is high, it will cause great impact on pressure sensors, relaysand motors, thus affecting the performance and life whole equipment. Therefore, it is necessary to choose the right volume of the pressure tank.

Answer: First of all, we must understand the relationship between pressure and lift: pressure = liquid density * g * lift (g = 0.981). In fact, the fire water pump can not only transport water, as long as the physical and chemical characteristics and water liquid are fine, but most of them transport water in daily life. The density of water is 1 ton per cubic meter. It can be obtained from the above formula : Pressure=1000*0.981*lift, pressure=0.981*lift, at this time the pressure and lift are almost the same, so whether we refer to lift or pressure, it can basically be regarded as a parameter.

A fire pump is a crucial component of a fire protection system that provides the required water pressure to deliver water to the fire sprinkler system or other firefighting equipment, ensuring an adequate supply of water in case of a fire emergency.

The DJ Fire Pump Set is a combination system consisting of a diesel engine pump and a jockey pump, designed for fire safety in the construction and industrial sectors.

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 sprinkler systems are hydraulically calculated prior to installation to determine adequate water flow and in order to ensure the system can reliably suppress a fire until fire crews arrive. When it’s determined inadequate flow is available from a municipal supply for the system to operate effectively, a fire pump is installed. The fire pump operates when the sprinkler system pressure drops below a certain threshold, due to the operation of sprinkler heads. The fire pump draws additional water from the municipal water supply or on site storage tanks, to maintain the sprinkler systems required operating pressure. Fire pumps are often required in high rise construction and large area buildings, due to the size of piping systems and pressure loss.
