micro Pressure and vacuum equipments

Vacuum bagging materials and fundamentals will translate to vacuum infusion (also called resin infusion), which is an even more advanced manufacturing process. Rather than using vacuum pressure to remove excess air and resin from within the laminate, infusion uses vacuum pressure to drive resin into the laminate.

  • Advantages of Pressure MF Systems Over Vacuum Systems | WWD

    Range of PressureImproved CleaningMore ReliabilityLower CostsFinal AnalysisPressure systems operate within a greater range of operating pressure, resulting in some advantages over vacuum systems. A limitation of vacuum systems is that they can operate only within the range of atmospheric pressure, typically operating at pressures approaching 70% of the maximum pressure differential available (10-11 psid). Pressure systems, on the other hand, rely on a greater reserve of pressure should upset conditions occur in the system, operating at 40 to 50% of the maximum transmembrane pressure (16-20 psig) when tested on the same waters. This builds an intrinsic safety factor into a design that allows the pressure system to better cope with process upset, changes in influent water quality or any other changes in plant operation. Pressure systems are also immune to the impact of temperature changes that affect vacuum systems. During winter, for example, feed water temperatures drop, which increases viscosity and the pressure required to force water through a membrane...

    The SI unit of pressure is 1 N / m² = 1 Pa. Other frequently-used units of pressure are: 1 mbar = 1 hPa = 100 Pa and 1 Torr = 133.322 Pa. If pressure is measured via the force that is exerted on an area, the pressure measurement is independent of the type of gas.

    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

  • Microfiltration - Wikipedia

    A pump is commonly fitted onto the processing equipment to allow the liquid to pass through the membrane filter. There are also two pump configurations, either pressure driven or vacuum. A differential or regular pressure gauge is commonly attached to measure the pressure drop between the outlet and inlet streams. See Figure 1 for a general setup.

  • Vacuum pump - Wikipedia

    A vacuum pump is a device that draws gas molecules from a sealed volume in order to leave behind a partial vacuum. The job of a vacuum pump is to generate a relative vacuum within a capacity. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.
