Portable Fire Fighting Water Pump Selection skills

Portable Fire Fighting Water Pump selection range is wide, because there are many kinds of models, and different models, the function will have a certain difference, in the face of so many models of Pump, consumers how to choose a suitable product, teach you several skills to help you make a choice:

1, when the water supply network has no regulation facilities, it is advisable to use speed regulating pump group or rated speed pump group to operate water supply. The water output of the pump group should not be less than the design flow of the water supply in the residential area, and should be checked with the fire fighting condition.

2, should choose high efficiency, low noise, energy saving pump.

3, when the single pump can meet the requirements, it is not suitable to use multiple parallel mode; The selection of water tank, water tower lift pump should minimize the number of fire pump, a standby; The type should not be more than two, the head range of single-stage water centrifugal pump should be similar; In parallel operation, each pump should still run within the range of high efficiency zone. If multiple parallel operation or large and small pumps must be used, the centrifugal pump model and number should not be too many. Portable Fire Fighting Water Pump

4, the characteristic curve should be selected as the pump head gradually decreased with the increase of flow; The operating point of the water pump should be kept in the high efficiency range. Fire pump should be selected according to the design flow, the required head, and considering the pump due to wear and other reasons caused by the pump output decline, according to the calculated head H multiplied by 1.05 ~ 1.10 coefficient after the pump.

5, the multi-stage pump unit of the living pressurized water supply system should be equipped with a standby pump. The water supply capacity of the standby pump should be greater than the water supply capacity of a running pump. The pump should be switched automatically and run alternately.

6, frequency conversion speed control pump design water supply flow should ensure to meet the requirements of the design second flow in the water supply system. Slurry pump power supply must be reliable.

The above introduction can help users, in the face of a variety of models of fire pump, how to choose their own products, its functions are many, and to understand its parameters more, and then to choose easier. Portable Fire Fighting Water Pump
