Fire Pump Equipment selection tips

Fire Pump Equipment has a wide selection range, because there are many types of Fire Pump Equipment, and different models, the function will be a certain difference, faced with so many types of Pump, consumers how to choose a suitable product, here are a few tips to help you make a choice:

1. When the water supply network has no regulating facilities, it is advisable to use speed regulating pump group or rated speed pump group to run water supply. The water output of the pump group should not be less than the designed water supply flow of the district, and should be checked under fire fighting conditions.

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; Selection of water tank, water tower lifting Pump should minimize the number of Fire Pump, one for use and one for backup; The model should not be more than two kinds, single stage clean water centrifugal pump head range should be similar; When running in parallel, each pump should still be running in the range of high efficiency area. If multiple parallel runs or size pumps must be used, the centrifugal pump model and number should not be too much.

4. The characteristic curve should be selected as the pump head gradually decreases with the increase of flow; The operating point of the pump should be kept in the high efficiency interval. The Fire Pump should be selected according to the designed flow rate and required lift, and considering the decrease of Pump output due to wear and tear of Fire Pump Equipment Pump, the Pump can be selected according to the calculated head H multiplied by 1.05-1.10 coefficient.

5. The multistage pump unit of the domestic pressurized water supply system should be equipped with a backup pump, and the water supply capacity of the backup pump should be greater than that of one operating pump. The pump should be automatically switched and run alternately.

6. The design water supply flow of the Fire Pump shall meet the design second flow requirements of the domestic water supply system. The power supply of slurry pump must be reliable.

The above introduction can help users, in the face of a variety of types of fire pump, how to choose their own products, it has many functions, and to understand its parameters more, and then to choose easier.
