Supply Shanghai oil diffusion pump heater dedicated supply manufacturers

Supply Shanghai vapor pressure oil diffusion pump heater dedicated supply manufacturers of vacuum pump oil directly affects the performance of the pump. However, any pump oil mixture used oil diffusion pump, the vapor pressure is much different components. Therefore, to improve the performance of the oil pumping and vacuum diffusion pump, the pump in the work itself but also to pump oil fractionation and purification. Fractionation purpose is to make a high vapor pressure component of the oil does not enter the working nozzle high vacuum (high vacuum side of the nozzle); purification purpose is to make a high vapor pressure component of the oil during operation continuously pumped to forepump addition, the oil becoming more pure. pump oil fractionation is the use of an evaporation temperature of the components of different oil pump, so that they evaporate in the boiler area were different. When returning after work condensate pump oil flow with a pump wall insulation cover part of the pre-heating oil that is obtained, then flows around the pan, the bottom of the pot ring heater, light distillate oil reaches the evaporation temperature will be in the outer evaporate into the low vacuum work nozzle (near the front pump nozzle); failure to evaporate some of the light distillates also due to the small proportion than other distillate oil and float to the surface. Because the outer limits of the vapor conduit, this part of the fraction was evaporated to still enter the low vacuum working nozzle. Heavy distillate oil vapor in the outer conduit evaporation temperature was not reached without evaporation, then flows from the outer pot by the gap between the center of the evaporation pan, into the high vacuum nozzle work. Light and heavy fractions of oil vapor lane so low supply and high vacuum nozzle vacuum work working nozzle that of the fractionation process. The oil discharged from the jet nozzle not fully preceding stage vapor cooling, steam in the light fraction that is not fully condensed before the pump is pumping. This cycle of work, the oil pump will be less and less light fraction, heavy fraction of the proportion is growing, pump oil will gradually become pure. This process is that of purification. Pump oil fractionation and purification, to improve the ultimate vacuum pump has an important role.
