The vertical turbine fire pump is the professional name of the dry motor fire pump. The motor is a dry motor and is not immersed in water. There is an “axis” inside the water pipe. It is suitable for extracting groundwater from deep wells or pools. It 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. It can also be used for city, factory, railway, mine, construction site drainage, and fire protection. The vertical turbine fire pump should meet the following conditions when it is used:
1. A three-phase AC power supply with a rated frequency of 50Hz and a rated voltage of 380+5% volts.
2. The water inlet of the pump must be below 1m of the moving water level, but the depth of the dive should not exceed 70m below the static water level, and the lower end of the motor should be at least 1m from the bottom of the well.
3. vertical turbine fire pumps requirements for water temperature should generally not be higher than 200℃.
4. vertical turbine fire pump also has several requirements for water quality
- The amount of sand in the water is not more than 0.01% (weight ratio);
- The PH value is in the range of 6.5 to 8.5;
- The chloride ion content is not more than 400mg / liter;
5. The vertical turbine fire pump requires the well to be straight and the wall to be smooth during installation, and there must be no manifold misalignment.
