Vacuum pump in electronic semiconductor industry application

Cleaning vacuum mainly uses negative pressure and atmospheric pressure difference for liquid or particle removal or transportation. This kind of application mainly uses water ring pump and multi-stage centrifugal fan. Because of low vacuum, multi-stage centrifugal fan is more used. Vacuum source is a part of its system....<<more>>

Vacuum - SensorsONE

Negative Gauge Pressure is the difference in pressure between any vacuum and atmospheric pressure. The maximum possible negative gauge pressure is always limited by the current ambient atmospheric pressure, which constantly varies, but is typically around 1 bar absolute....<<more>>

Vacuum technology - AERZEN

A pressure of -700 mbar (300 mbar abs.) is considered as negative pressure. Below 300 mbar absolute the vacuum range begins, subdivided in rough, fine, high and ultra high vacuum. Below 300 mbar absolute the vacuum range begins, subdivided in rough, fine, high and ultra high vacuum....<<more>>

Vacuum pump application - Pump engineering - Eng-Tips

I understand that this is not really the real application of a vacuum pump but I am not given the budget to purchase a new extraction fan etc. The problem I face now is that the spare pump that I have is too large, even with a suction pressure of ca. 800 mbara, my flowrate (from pump curve) is still around 140m3/h....<<more>>

Rotary vane vacuum pump in food processing application

The Application of Skin Adhesive to Maintain Seal in

Negative pressure wound therapy is a cost-effective mechanism in treating wounds 9,10; however, air leaks from anatomically difficult wounds may add additional expense by increasing the frequency of dressing changes and by delaying wound healing. This additional expense may be eliminated with application of a tissue adhesive, since it potentially optimizes the wound healing process by ...<<more>>

Principal Applications for Steam | TLV - A Steam

However, a vacuum pump must be used in conjunction with the equipment, because merely reducing the pressure will not drop it to below atmospheric pressure. Heating with Latent (Steam) Heat Compared with a hot water heating system, this system offers fast, even heating....<<more>>

Multi-stage Roots pumps – Vacuum processes

Extensive knowledge of vacuum technology and vacuum process technology is required to define a practicable solution with long-term stability and minimum cost of ownership. This, for instance, includes defining the pump working temperature in order to prevent condensation due to too low a temperature, powder formation at too high a temperature or blockage of the pump if the chemicals remain in ...<<more>>
