Water pump designed irrational factors
|Design pump water from the condensate pump outlet, as a result of condensation of water temperature is generally lower than the exhaust temperature 1 ℃ ~ 2 ℃, while due to work pressure pump condenser pressure lower than about 0.6kPa, corresponding to the vacuum pump discharge water temperature should be higher than low temperature steam about 3 ℃, after the fact, causing water to enter the vacuum pump water system, to vaporize and release heat, thereby reducing the vacuum pump capacity.
On the other hand, due to the condensation of water pressure, water valves are likely to cause damage, affecting the normal water level control.
Improved Method pump water wayPump water from the condensate into demineralized water, fill the condenser water pipe access. 2:00 This is mainly benefits: First, reduce the water temperature of the vacuum pump favorable. The second is to reduce water pressure on the replenishment equipment working life benefit.
The inner gas-water separator level directly affects the performance of the vacuum pump. The pumping gas contains steam, it is possible to condense into water leaving the water level increases, the vacuum pump motor power increases; but more likely drawdown (even water) leaving the pump performance degradation, leading to the condenser pressure changes affect the efficiency of the generator set. At this time it is very important to control the water level. Generally conventional mechanical float control valve, the water level is kept within a certain range, you can automatically discharge high water flow mayonnaise. As a precaution, in communicating with the separator site is also equipped with a magnetic level gauge, the lower limit alarm switch, wired to the control room, providing long-distance water level alarm
