The Fundamentals of Vacuum Theory

Aug 10, 2018 · As a result they can generate a high throughput and provide a quick drawdown in the roughing and low vacuum phases. Pumps used to create high and ultra-high vacuum include diffusion pumps, cryogenic pumps, and ion pumps and must operate in the molecular flow range. They therefore use different technology than roughing and low-vacuum pumps.

Vacuum Pump Capacity Ratings - Technical Data | Dekker .

The capacity for vacuum pumps is specified in a couple of different ways, depending on the type of vacuum pump and the manufacturer. It is important to know the ACFM rating of the pump, which expresses the "actual cubic feet per minute" inlet capacity at a specific vacuum level.

How about high temperature of vacuum pump?- Vacuum Pump .

Causes of high temperature problems of vacuum pump: (1) high power and working current of the motor lead to high temperature of the vacuum pump. (2) the number of fan blades is small, and the amount of wind generated is small. (3) low fan speed, air pressure and small air volume. (4) the bus voltage of the vacuum pump motor is 380V.

Maintenance Tip: Monitoring Pump Operating Temp. | NASH

This is especially important in hot weather. Compressors generally have 10°F "approach" heat exchangers, because the water temperature isn't affected as much as it is with vacuum pressure. High water temperature will affect the vapor pressure and prevent good vacuum performance. When testing, record all of the temperatures on the check sheet.
