Awareness of the possibilities will save time in setting up a system. The pump is designed to remove air from a vacuum system at atmospheric pressure to a deep.

When the pump is operated at elevated pressures up to about 10 Torr for long periods of time, the pump will run hotter. At elevated ambient temperatures under these conditions, the thermal protection switch on single phase motors may cut out. Do not run this pump for prolonged periods of time at or above 10 Torr. Leaky vacuum systems, too large a vacuum chamber for pump size or high gas loads to the vacuum systems are causes for extended runs of the pump at elevated pressure.

If you need additional information, please contact Welch Vacuum at , extension 1, for further information and precautions. Water, oil and a mercury vapors are three of the more common vapors encountered in typical vacuum systems. This emulsion is recirculated to the chambers of the pump where it is again volatilized causing increased pressure within the system. Condensation takes place particularly in the compression stroke of the backing or second stage of a two-stage pump.

The compression stroke is that portion of the cycle during which the gas drawn from the intake port is compresses to the pressure necessary to expel it past the exhaust valve. Condensation takes place when the ratio between the initial pressure and the end pressure of the compression is high, that is, when the mixture of vapor and gas drawn from the intake port is compressed from a low pressure to high pressure.

By adding air though the gas ballast valve to the mixture of vapor and gas being compressed, the pressure required for delivery past the exhaust valve is reached with a considerably smaller reduction of the volume of the mixture;.

In a pump functioning on a contaminated system and operating without the gas ballast, compression within the stage takes place in the normal manner until the saturation pressure of the contaminating vapor contained within the mixture of gas and vapor is reached.

The saturation pressure of water vapor is that pressure and corresponding temperature at which the dew point of the vapor is reached and condensation occurs. The external side of the exhaust valve. Consequently a compressive force somewhat greater than atmospheric pressure is required to open the valve and permit expulsion of the gas. Sometime during increased compression of the mixture of gas and vapors, the saturation pressure of Torr for the water vapor is reached and the vapor condenses. The condensate is then allowed to emulsify with the oil which is recirculated within the pump stages this providing continued contamination of the system.

On the other hand, when ballast air at atmospheric pressure is supplied to the compression stroke by means of the gas ballast, the partial pressure of the unwanted vapor becomes a very small part of the total pressure of the mixture of gas, vapor and newly supplied air. With the gas ballast open, the sound of the exhaust is similar to that of a pump operating against a large leak. Tests have shown that continuous and prolonged operation for several weeks under these conditions is not injurious to the pump.

The application of the gas ballast is a moderate and very successful method for the removal of condensable vapors. For very heavily laden systems, other means of removal such as oil separators may be required. For mild cases of contamination the simple expedient of a cold trap or a change of oil serve the purpose.

The importance of eliminating all leaks in a vacuum system is obvious when it is realized that a leak into the system, at atmospheric pressure, expands in volume by a factor of , to 10,, or more. The pump must remove this added volume to maintain the desired vacuum.

Fortunately a. Large leaks can be located by pressurizing the system and painting the suspected area with a thick soap solution. Escaping air will produce soap bubbles. Small leaks may also be detected by spraying a suspected area with acetone or gases rich in hydrogen, and observing a sudden change in pressure on an electrical gauge. The difference in calibration of these gauges, for air and other gases, will produce a distinct change in the pressure reading.

To use this method of detection, the system must be under vacuum and the gauge sensing tube must be located between the pump and the area to be probed. This instrument will locate leaks which cannot be detected by any other method.

A few simple precautions are all that is necessary when shutdown is in order. If the pump is removed from the system, cover the intake port with a rubber stopper or suitable cover to protect the pump against contamination and loose particles. Leakage, contamination and unusual outgassing are the general causes of problems associated with poor vacuum.

If the system is completely clean and free from leaks, and unwarranted vacuum problems still exist, the pump should be checked.
