The working conditions of Vertical turbine fire pumps

2021-02-06

Vertical turbine fire pumps are widely used in water plants, hydropower stations (pumps for maintenance, leakage and drainage, etc.), thermal power plants (pumps for industrial, domestic, and fire fighting, etc.), and steel plants (pumps for circulating cooling, daily life, iron pits, etc.) , Agricultural irrigation, fire protection, municipal administration and other industries, using Ashland resin technology to make cores, and epoxy coating on the runners of the blades.
The following introduces the working conditions of the turbine fire pump:
1.The load power of the transformer should not exceed 75% of its capacity. The rated frequency is 50 Hz, and the rated voltage of the motor terminal should be guaranteed to be a three-phase AC power supply of 380±5% volts.
2. Generally non-corrosive clean water, the solid content (by weight) in the water is not more than 0.01%.
3. When the transformer is far away from the wellhead, the voltage drop of the transmission line should be considered. For motors with a power greater than 45KW, the distance between the transformer and the wellhead should not exceed 2 meters. When it is greater than 20 meters, the transmission line specifications should be two larger than the cable specifications. grade, and consider the line voltage drop.
4. The water temperature is not higher than 40℃, the pH value is in the range of 6.5~8.5, and the hydrogen sulfide content is not more than 1.5 mg/L.
