Cryogenic trap main characteristics: cool quickly, within three minutes cooling to -120 ℃, the lowest up to -145 ℃; rapid adsorption of water vapor, oil vapor, shorten evacuation time from 60% to 95%; 3 minutes hot gas defrost , warmed rapidly; control system with touch screen + Siemens PLC, more grades; with local control, remote control interface, compatible with any vacuum system, clients can access Coater automatic control system; standby temperature indicator; maintain long-term continuous operation ; cryogenic trap, a device can be designed dual load output; can be designed dual load outlet and return port temperature display, the machine temperature display; imported brands dedicated cryogenic compressors, various control valves using imported components, stable and reliable ; high pressure compressor protection, exhaust temperature protection; easy to install, simple system transformation; power, high water temperature alarm and protection; compact structure, small size, light weight cryogenic trap application principle: in high vacuum environment, there is a certain degree of 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. Reasons steam, oil vapor and other residual gases produced: ultra-low temperature trap in a high vacuum environment, there is a certain degree of 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% - more than 95% of the remaining gas; at the same time, due to the vacuum pump in the course will inevitably produce pump oil evaporation phenomenon, and therefore there will be a small amount of oil vapor into the vacuum system. Cryogenic trap pump applications principle: 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, water vapor, oil vapor condenses rapidly 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.
