Portable Fire Fighting Pump Factory Lift selection

Fire pump is suitable for pressurized water delivery in fire pipeline. It is used to transport water or other liquids similar to water in physical and chemical properties for pressurization. Horizontal pump medium temperature is not higher than 80℃, suitable for industrial and urban water supply and drainage, high-rise building pressurized water delivery, garden irrigation, long-distance water delivery, heating, bathroom and other cold and warm water cycle pressurization and equipment supporting.

Portable Fire Fighting Pump Factory is an important working performance parameter of Pump and also an important factor to determine its use effect. Then how much is the head of Fire Pump? The head of fire pump is generally 30~180 meters, and 40~130 meters is a commonly used parameter comparison table。

The head selection of fire pump should pay attention to the following two points:

1, choose the fire pump head can not be too small. Portable Fire Fighting Pump Factory According to the provisions of Fire hydrant, for high-rise buildings, factories, warehouses, indoor clearance to 8 m civil buildings, Fire hydrant outlet dynamic pressure is not greater than 0.35mpa, and calculated according to 13 meters of water column. In other places, the dynamic pressure of fire hydrant outlet shall not be greater than 0.25mpa, and the expanded water column shall be calculated as 10m. For example, in a residential building 30 meters high, the dynamic pressure of the outlet of the fire hydrant on the top floor should not be greater than 0.25mpa, and the pump with a head greater than 55 meters should be freely selected.

2, when choosing the pump, the head can not be too large. The outlet dynamic pressure of the fire hydrant should not be higher than 0.5 Mpa. When it reaches 0.7 Mpa, a pressure device should be set. Also take a residential building 30 meters high as an example, the head of the fire pump can not be higher than 80 meters, otherwise it will cause waste, and the bolt outlet dynamic pressure is too large, the dynamic pressure is too large and the pressure reducing valve is set, causing secondary waste.
