What are the cause of the vacuum pump injector can't run -

some market users report that they buy complete sets of equipment of vacuum pump failure, the injector can not be put into operation 'accounts for the largest proportion, lead to the output of the vacuum pump limited, influence the improvement of the condenser vacuum. It has a great influence on the unit economy. 6 sets of vacuum water pump vacuum pump spray cannot be put into operation in low temperature season, the output of the vacuum pump is restricted, lead to condenser vacuum. Vacuum pump injector can not put into operation 'now the fault eliminated, the output of the whole equipment increased, condenser vacuum in low temperature season increased by 0. 8000 mpa.

a, this paper analyzes the reason of the injector can not put into operation:

1, vacuum pump, injector bypass valve leakage

2, increased mechanical wear

3, increased mechanical wear

4, insufficient maintenance

5, the improper maintenance

6, improper maintenance standard

7 high cooling water temperature, low temperature season

8, vacuum pump injector excessive air moisture content

9, vacuum pump injector flow adjustment improper

inspection found that the main reason is that ejector no internal leakage by-pass valve, injector surface temperature is stable, not below 0 ℃. Check the injector temperature difference before and after the bypass valve at 8 ℃ ~ 15 ℃, indicating that the valve internal leakage is serious, directly affect the output of vacuum pump complete sets of equipment. Injector after put into operation, rapid changes in temperature from room temperature to - the catheter 15℃。 Condenser vacuum fluctuations is very big. Check if the vacuum pump injector inlet pipe contains a lot of water.

2, solution:

1. Vacuum pump injector air source was changed for the relatively low humidity of the atmosphere. Vacuum pump injector air into the atmosphere, also installed the manual isolation valves and filters.

2。 In order to eliminate the internal leakage of the valve, valve repair after transforming, rationalisation for complex type check valve, the high reliability of pneumatic rubber lining butterfly valve is used to eliminate internal leakage.

after implementation, the comparison results show that the vacuum pump injector has been put into normal operation. Under the 558 mw load, condenser vacuum improve 0 B side. 88000 mpa, exhaust temperature by 2. 77℃。 But the transformation cost is 100000 yuan, coal consumption reduce 1. 8 g/kWh, save coal, 5184 tons a year, power generation cost savings of 2. 3 million yuan, reduce CO2 and SO2 emissions.
