Priced at direct cryogenic trap pump manufacturers in the actual application, depending on the location of the place can be divided into two categories (see figure): 1, water vapor trap its cooling coils are often installed between the valve and the vacuum chamber or high vacuum chamber, web coating and other parts of the upper and lower interior. Suitable for low temperature plastic coating, web coating and other coating materials are outgas larger occasions. Heating coil requires defrosting device, so that the coil to return to room temperature before you open the door each time, to avoid hypothermia coil to absorb large amounts of water vapor from the atmosphere and frost, affecting the next evacuation. 2, ultra-low temperature cold trap on the pump inlet oil diffusion pump, high valve below, which main function is to prevent the oil diffusion pump oil back, but can also speed up the pumping speed, increase the vacuum. Because the system in a vacuum, without defroster. Cryogenic trap pump manufacturers direct factory price required, both can be installed separately or simultaneously install: cryogenic trap pump manufacturers direct factory price Main features: cool quickly, within three minutes cooling to -120 ℃, the lowest up to -145 ℃; fast adsorb 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, and any vacuum compatible, you can access client Coater automatic control system; standby temperature indicator; maintain long-term continuous operation; a piece of equipment can be designed dual load output; can be designed dual load outlet and return port temperature display, the machine temperature display; imported brands hypothermia dedicated compressor, various control valves using imported components, stable and reliable operation; 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 pump condensing coil priced at direct factory production: according to the actual situation of equipment, we can help you make the condensing coils of different shapes. Cryogenic trap pump manufacturers Priced at direct input and output interface: condensing coil from the vacuum chamber through the wall, due to the large temperature difference between the pipe wall temperature and, if the direct welding, there will be a greater loss of cooling capacity, the chamber 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. Application of principles: 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% ~ 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.
