Rotary vane vacuum pump - pollution problems in the process of application processing

granular material in the process of rotary-vane vacuum pump are used and vapor or liquid form disgusting pollution.

because of rotary-vane vacuum pump itself inherent self compensation gap adjustment effect, so it is not particularly sensitive about small body injury. In most of the design, the choice of sliding bearing is smaller than ball bearings on the sensitivity of the dust. Once the dust comes off the oil by gravity, oil pool produce sediment, it is not involved in the oil circulation, until it is removed. For these dust particles, can oil pu filter, but it seems to be not worth it. If pollution is serious, the filter replacement too to be numerous, simple as an oil change. In dust particles into the pump before, had better to stop in the processing of location. To this, the dry filter and oil capture trap is the most effective. The selected protection methods should depend on the size, processing dust particles size and allowed pressure drop. In abrasive dust, parts of pump should be higher surface hardness, to prolong service life.

exposure to low vapor pressure of the material are not uncommon. These substances condensation in the pump, and mixed with lubricant, or make the lubricant diluted, or into the lacquer and colloidal sediment. Gas ballast method could do about it. When is the best way of the vapor reach rotary-vane vacuum pump before to block it. But in many cases, it is not satisfactory, because in such a wide range of pressure of work, it is difficult to design effective trap, or due to have certain pollutants trap maintenance became a difficult problem. At this point, the solution of most used oil change on a regular basis.

corrosive pollutants, especially when its small volume, can be controlled. Lubricating oil can be in most of the metal surface and ACTS as a buffer between corrosive. In addition, such as to prevent the condensation of water, the harm of its corrosion resistance becomes rather limited. Use dry the isolation effect of the gas can effectively prevent condensation in the atmosphere in the separator. Kept slightly high pressure separator in dry gas, can put an end to ring slope humidity on the influence of the rotary-vane vacuum pump oil.

soluble steam are those that can dissolve in oil and on the entry side of the rotary-vane vacuum water pump are released to the hard material to gas town method. At that time, it is best to use double pump. Atmospheric level of oil viscosity to keep working in tableland can extent. before use is not sensitive to the pollution of oil or vacuum distillation to purify oil regeneration are able to work well.
