Axial flow deep well fire pump is the professional name of dry motor fire pump, the motor is dry motor, not soaked in water. There is a “shaft” inside the lift pipe. It is suitable for extracting groundwater from deep wells or pools, and is also suitable for water extraction projects such as rivers, reservoirs, and canals; it is mainly used for farmland irrigation and water for humans and animals in plateau mountainous areas, and can also be used for drainage and fire protection in cities, factories, railways, mines, and construction sites For water use. The axial flow deep well fire pump must meet the following conditions when in use:
1.A three-phase AC power supply with a rated frequency of 50 Hz and a rated voltage of 3805% volts.
2.The water inlet of the pump must be 1 meter below the dynamic water level, but the diving depth must not exceed 70 m below the static water level, and the distance between the lower end of the motor and the water level at the bottom of the well is at least 1 m.
3.The water temperature requirement of axial flow deep well pumps should generally not be higher than 200 degrees Celsius.
4.Axial flow deep well fire pumps also have several major requirements for water quality
(1) The sand content in the water is not more than 0.01% (weight ratio);
(2) PH value is in the range of 6.5~8.5;
(3) The chloride ion content is not more than 400 mg/L;
5.When installing the axial-flow deep well fire pump, it is required that the well is upright and the inlet wall is smooth, and there must be no staggered weed pipes.
