Small Flow EDJ Fire Pump Set

Fire pumps are necessary because municipal water supplies might not always provide sufficient water pressure to effectively fight fires in large buildings or areas. Fire pumps boost the water pressure to ensure proper coverage and firefighting capabilities.

At the morning of the design of the fire pump, the lift, inflow and power are different according to the occasion and model. In general domestic structures, the choice of fire pump is also different according to the age, the height of the bottom, and the number of residers.

The fire pump is used for conveying clear water without solid patches and liquids with analogous physical and chemical parcels to water. Water force, heating, restroom, boiler hot and cold water rotation, water force of pressurized air exertion refrigeration system and outfit matching and other occasions.

Horizontal end suction electric fire pumps designed as main pumps for fixed fire protection systems, delivering high flow capacity, stable pressure, fast startup, reliable continuous operation, and efficient performance for building and industrial fire safety applications.

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.

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.
