Display dispenser manual mechanical vacuum pump technology

With the operation and the pump oil circulating pump, in return for high vacuum end will re evaporated into steam. Will affect the pumping performance, increase the pump oil pollution. Set the gas ballast valve can effectively prevent the condensation of condensable gases, namely the display dispenser in the compression process, gas ballast valve gas dispensers through the gas hole of the permanent dry gas mixed with compressed gas, condensable gas partial pressure in the pump when the temperature reaches the saturation vapor pressure, pressure display dispenser of compressed gas can reach exhaust pressure, exhaust valve is opened, the condensate and dry gas discharged simultaneously. Normally the oil seal mechanical pump gas ballast valve are arranged, it can refer to the manual mechanical vacuum pump oil seal technology. This pump is easy to return oil and fuel injection, in order to overcome these shortcomings, the manufacturer at the same time with the molecular sieve, oil mist collector, dust filtration and oil filter and other accessories.
