1) Causes:
A, the pump running direction does not match the requirements.
B, multi-stage pump inlet pipeline air.
2) Solution:
A, check the power cord wiring, pump steering requirements and pump casing labeled the same.
B. Unscrew the evacuation bolt of the multi-stage pump to remove the internal air.
2, distilled water quality problems
1) the cause:
A, distilled water temperature is too low.
B, the evacuation port is not smooth.
C, during operation, the evaporator water level line exceeds the observation window.
D, raw water quality does not meet the requirements.
2) Solution:
A, reduce the cooling water flow, control the distilled water outlet temperature between 92-99 ℃, and ensure that the exhaust port is smooth, so that non-condensable gases are smoothly discharged from the machine.
B, the operator in the process of equipment operation, should always observe the water level line of each effect of the evaporator shall not exceed half of the observation window, and always observe the changes in steam pressure and raw water flow, timely adjustment and control.
3, distilled water production is not enough:
1) the reason:
A, the supply of heating steam quality does not meet the requirements, that is, the heating steam is not dry saturated water vapor.
B, an effect of the evaporator, an effect of the preheater trap clogging, poor drainage.
C, the heat exchanger tube wall may have accumulated scale.
2) Solution:
A, improve the quality of heating steam
B, check the trap, depending on the situation for cleaning or replacement.
C, an effect of the evaporator through the boiler steam with impurities, heat exchanger tube wall is easy to scale; condenser when the tap water is used as cooling water, easy to make the cooling tube scaling, and thus an effect of the evaporator condenser should be regularly descaling and cleaning as appropriate, the specific operation of the cleaning content.
