Steam boiler room of desuperheating water pump selection considerations

Steam boiler room of desuperheating water pump selection considerations:

(1) the shaft seal to choose mechanical seals, especially the steam boiler room of desuperheating water supply pump. Although using packing seal maintenance simple, high failure rate and repair rate, big workload. Therefore, we should choose mechanical seals, life should be greater than 8000.

(2) boiler desuperheating water pump motor is the power source of the water pump operation, if the motor fault occurs, the pump can't run. Therefore, the structure and the insulation level of the motor should meet the requirements of installation and use of the environment, to ensure the safe operation of the motor.

3. If choose frequency conversion water supply, the selection of pump head should be slightly higher than the designed value. Due to the water pump in operation after 3 ~ 5 years, with the enlargement of the impeller wear and clearance, head drop 20 ~ 30 m, so choose the pump head should be about 30% higher than design value, to ensure normal water supply and water pump after years of good energy saving effect of the frequency converter, so as to prolong the service life of pump.

(4) when the feed temperature to room temperature, not special instructions in use. If water temperature > 100 ℃, it shall be when choosing pump feed temperature is emphasized. This is due to the high temperature and low temperature pump on the material, structure and the function of cavitation is different.

5. When the pump inlet's highest position below the water tank ( Or pool) When the liquid level, when the choice without any special instructions. When the boiler room of desuperheating water water pump inlet position higher than the highest water tank ( Or pool) When the liquid level, should choose strong self-priming pump.
