28. tight otherwise the precision valve seat may get damaged The function of the gas ballast valve is to enable condensable vapours to be discharged through the pump with minimum oil contamination depending on the nature and quantity of the vapour s involved As vapour will condense back into its liquid form upon compression at or greater than its Saturation Vapour Pressure SVP this can present a problem with high vacuum pumps which have a suction and a compression cycle It is necessary during the compression cycle of the pump to compress the system gas from the suction port at or greater than atmospheric pressure in order to lift the exhaust valve allowing them to be discharged In a vacuum system containing a quantity of water for example the air is quickly removed by the vacuum pump and the partial pressure of the water in the system will increase When the partial pressure of the water vapour of the system gas reaches it s SVP during the compression cycle of the pump it will condense back into a liquid and mix with the oil At this stage the vacuum pump CANNOT achieve a vacuum better than the SVP of the water This is because the water evaporates from the oil on the suction cycle and then re condenses back into the oil during the compression cycle The water in the oil therefore becomes a source of vapour that the pump must contend with If however we reduce the partial pressure of the water vapour during the pump s compression cycle with a m
