Domestic sales POLYCOLD POLYCOLD POLYCOLD agent vapor pump cryogenic trap trap trap pump cryogenic pump cryogenic trap ultra-low temperature cold trap POLYCOLD manufacturers POLYCOLD maintenance application principle: in a high vacuum environment, there are some residual gas. Since water has a molecular weight of less than molecular oxygen, nitrogen and other major components of air, therefore, whether or molecular diffusion pump oil pump, they can not quickly and effectively pull it out, therefore piled up, finally becoming the residual gas accounts for 65% ~ 95% of the residual gas; Meanwhile, since the vacuum pump in the course of which is caused by the evaporation of the oil pump, there will be a small amount of oil vapor into the vacuum system. A due to the presence of water vapor and oil vapor, causing the vacuum system can not quickly reach the customer with the desired degree of vacuum, resulting in evacuation time becomes longer, the production efficiency drops, a desired degree of vacuum higher the humidity, the more obvious impact . Second, at the same time, water vapor, the presence of oil vapor will cause the film decreased firmness, can not multi-coated, color uneven first-class. Three steam will, under certain conditions ionization, produce oxygen, so that the target oxide, resulting in coating color change. Ambient humidity, the higher the temperature, the higher the desired degree of vacuum, the greater the effect. Therefore, steam, oil field steam vacuum coating and high vacuum to obtain a gas main hazard areas. Cryogenic trap gas pump and vacuum pumping different, he is able to reach -120 ℃ following a cooling coil, cabinets or placed in a vacuum diffusion pump oil pump port, use Meissner principle, the water vapor, oil vapor rapidly condenses In the cooling coil surface to achieve rapid evacuation, increase productivity, improve the quality of the purpose of the coating. Therefore, the low temperature trap vacuum pump is used in conjunction with, compared to using a separate vacuum pump will substantially increase productivity, improve product quality. Rapid absorption of water vapor in the vacuum system, oil vapor, effectively shortening the evacuation time of 30% to 90%, improve the coating quality, completely solve the film uneven color, easy off phenomenon.

Domestic sales POLYCOLD POLYCOLD POLYCOLD agent vapor pump cryogenic trap trap trap pump cryogenic pump cryogenic trap ultra-low temperature cold trap POLYCOLD manufacturers POLYCOLD maintenance input and output interfaces: condensing coil from the vacuum chamber through the wall, due to pipeline temperature and the wall temperature difference, if the direct welding, cold will have a greater loss severe frost wall. This requires a length of about 20 cm of thin-walled stainless steel tube made of insulating means to solve, it can be made to live on (see photo), you can not seal, soldered directly to the vacuum chamber wall.
