Busch 0532140159 vacuum pump oil mist separator filter structure typically have paper, metal mesh filter composed of surface and both ends of the plastic cover. Its core component is inside the filter, in the case of relatively good filter paper produced in Germany, with strong separation ability. Busch 0532140159 vacuum pump oil mist filter works in the role of driving force separator located in the side of the fuel-air mixture through the vacuum pump oil mist separator filter paper and cotton. Oil were trapped in order to achieve the process of separation and vacuum gas oil. It is filtered out of the vacuum pump oil return pipe for recycling with the discharge of the oil-free exhaust, to achieve pollution-free, clean effect. Busch 0532140159 routine maintenance a vacuum filter pump run-time checking: using a vacuum gauge to detect oil mist separator is blocked, when the gauge is located in the red area, indicating that the oil mist separator clogged and must be replaced. If there is no oil mist separator pressure gauge, the oil mist separator resistance changes by the drive motor current is measured, excessive consumption of the drive motor current or pump flow rate decreased, indicating that the oil mist separator clogged and must be replaced. b. If the pressure gauge indicates the vacuum pump oil mist separator is usually lower than, or the drive motor current consumption is typically less than, because there is an oil mist separator is damaged, you need to replace the oil mist separator.
