Means through which air or another non-condensing gas is admitted into a vacuum pump are referred to as gas ballast. If the pump is displacing vapor that would condense in the pump at the corresponding temperatures without gas ballast, the gas ballast enables the outlet valve to open before the vapor condenses, and the vapor is discharged together with the ballast gas. Both atmospheric air as well as selected inert or process gases are used as ballast gas. The use of the gas ballast increases the attainable base pressure of a vacuum pump slightly. Consequently, for gas ballast vacuum pumps the base pressure is specified both with and without gas ballast.
The vacuum pumps are shipped and contain a feature known as the gas ballast valve. This is viewed as a black adjustable knob on top of the pump.
Often in vacuum work, the user will get water vapor, solvent vapor or other bad contaminants as part of the gas stream being evacuated from the vacuum chamber. These contaminants come over because they have turned into a gas molecule from a liquid molecule under "X" vacuum pressure and the pump pumped them out of the system. They then travel to the pump and turn back from a gas to a liquid in the pump oil....

The electrodelessdischarge lamp, which may enhance thermal performance to achieve high output. The electrodeless discharge lamp comprising: a bulb filled with a discharge gas; and a coupler, the coupler is received in the cavity formed by the lamp, for generating high frequency electromagnetic field. The coupler comprises: an induction coil; into the core of the induction coil; thermal conductor for conducting the heat generated by the coil and the core; and a resin bobbin, for receiving the core and the heat conductor, and coil is wound on the bobbin. As the coil bobbin along the radial direction can be demolished, it can be molded independently of each part of the bobbin. Thus, the molded tube can be omitted when the bobbin is usually necessary draft angle, the bobbin can be made thinner and uniform, and by reducing the volume of the bobbin in the cavity to increase the proportion of thermal the thermal conductivity of the body....
