About vacuum pumps: Q: How is vacuum measured? A: one standard atmosphere at standard conditions will support a column of mercury 760mm high. This is where the linear measurement in vacuum comes into play.760mm can be also measured in inch Hg (760mm = 29.92″) and microns (760,000 microns = 760 mm = 29.92″). Depending on what vacuum level you require, you will use a different unit of measure for the vacuum measurement. When measuring vacuum below 1 micron, we go to scientific notation (Example: 1 x 10-3 mm Hg) Q: What is an Absolute vacuum gauge? A: An absolute pressure gauge is one that will measure your vacuum system without regard to and independent of local barometric pressure. Many dial (Bourdon) gauges and electronic Transducers reference local barometric pressure as their base measurement. However, since these devices are calibrated at SEA LEVEL conditions, operation of these devices above sea level will cause an erroneous reading. Either the gauge/transducer must be recalibrated for the higher elevation use or an absolute pressure gauge would need to be used. A Torr gauge is an absolute pressure gauge and operates on the principle of an altimeter. The Gauge case is evacuated by the vacuum from the process and exerts a negative pressure on a hermetically sealed capsule. The lowering of the pressure in the gauge case causes the capsule to expand thereby causing the gauge movement to turn the pointer. The Torr gauge is highly sensitive and accurate in the lower pressure regions (0-100 mm Hg). Q: how to judge vacuum degree? A: Atmospheric Pressure- is variable but is standardized at 760 Torr or 101.325 kPa. Low Vacuum- also called rough vacuum, is a vacuum that can be achieved or measured by basic equipment such as a vacuum cleaner. Medium Vacuum- is a vacuum that is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer. It can be measured with a McLeod gauge, thermal gauge, or a capacitance gauge. High Vacuum- is vacuum where the MFP of residual gasses is longer than the size of the chamber or of the object under test. High vacuum usually requires multistage pumping and ion gauge measurement. NASA has revealed that the vacuum level recorded on the moon was 1×10-9 Torr. Ultra-High vacuum- requires baking the chamber to remove trace gasses and other special procedures. Most standards define ultra-high vacuum as pressures below 10-8 Torr. Deep Space- is generally much emptier than any artificial vacuum. Perfect Vacuum - is an ideal state of no particles at all. It cannot be achieved in a laboratory, although there may be small volumes which, for a brief period, happen to have no particles of matter in them. Q: what type of vacuum pump should I choose for my application: A: There is no one vacuum pump that is best for all applications. However, there are some general guidelines to remember for your selection. Oil Lubricated Rotary Pumps are used in applications requiring fairly deep vacuum (< 1 mmHg) and pumping relatively clean gases (Air/N2). Oil lubricated pumps are available in Single stage & Dual stage depending on what vacuum level you need. Additionally, all the oil lubricated pumps are available in Belt drive or Direct drive configurations. Belt drive is preferred in applications where pump longevity and durability is desired because of the low pump rpm (<700 rpm) and their high oil holding capacity which also guards against premature wear from oil breakdown. Direct drive pumps are preferred because of their low cost, compactness and portability. Dry Vane pumps; are used when a pump is required that does not require lubricating oil because of the objection to oil vapor discharge from the pump and filling/disposal issues with oil. Rotary vane dry pumps however are capable of only maximum vacuum of approximately 25″ Hg and can only pump clean DRY air. Any presence of moisture in the gas being pumped can lead to the pump rusting because of the absence of lube oil. Rotary Screw Dry Pumps are used in applications where a high vacuum is required (up to 0 .010 mm Hg) and the process gas is not compatible with lubricating oil in oil sealed rotary pumps. These pumps are fairly expensive and are used where a lubricated oil sealed pump or liquid ring pump is not desired. Pleasure email us for more details. Liquid Ring Pumps are used in applications where the process gas may contain a sizable amount of condensable vapors (water, solvents, acids, etc.) that will react negatively with the lubricating oil in Rotary Vane pumps, thereby causing pump damage. Being that a liquid ring pump is a centrifugal unit, the sealing medium can be water, oil or any other fluid compatible with the process. Liquid ring pumps are relatively inexpensive and can use any sealing fluid (water, oil, ethylene glycol, solvents, etc.) that is compatible with the process. Q:what is gas ballast on vacuum pumps? A: A gas ballast is a regulated in-bleed of a dry gas (usually Air/Nitrogen) into the compression portion of the pumping cycle of the vacuum pump. The gas acts as a stripping agent that will saturate with the contaminating vapors present in the pump and expelled out the discharge of the pump. Gas ballasts are usually installed as a standard component on all oil lubricated rotary vacuum pumps to aid in the removal of condensable vapors from the vacuum pump oil.
