The water jet vacuum pump can better withstand high temperature differences, so the pump can withstand high temperature and has a longer service life than the same type of pump. The pump is suitable for the electronic industry, such as electronic tubes. Picture tube. X-ray tubes, as well as the smelting and purification of semiconductor single crystal silicon, the distillation and purification of high-boiling point oils and fats, fluorescent lamps, and high-vacuum exhaust equipment for thermos flasks. Baker vacuum pump carbon sheet The working principle of various vacuum pumps, working principle First, the system is pumped to 10-2Pa by the rotating vacuum pump. The diffusion pump oil is heated and boiled, and the gas molecules in the system are continuously brought to the bulb of the side arm elbow of the pump at a high speed from the ejected oil vapor flow. When the gas density reaches The working range of the mechanical vacuum pump is drawn out, so as to gradually obtain a high vacuum. It can be used alone or as a booster pump, a diffusion pump, a fore pump of a molecular pump, a maintenance pump, and a pre-pump of a titanium pump. It can be used for electric vacuum container manufacturing, vacuum welding, printing, blister, refrigeration equipment maintenance and instrumentation equipment and laboratories. It is widely used in food, scientific research, medical, electronics, chemical, pharmaceutical, colleges and universities and other departments. Using mechanical, physical, chemical, physical chemistry and other methods. At present, the most widely used in industry are water ring vacuum pumps and rotary vane vacuum pumps. One of the basic equipment used to extract gas from closed containers. It can be used alone or as the backing pump of booster pump, diffusion pump and molecular pump. This type of pump is widely used in vacuum smelting, vacuum coating, vacuum heat treatment, vacuum drying and other processes in metallurgy, machinery, electronics, chemical industry, petroleum, medicine and other industries. It has the advantages of compact structure, small size, light weight, low noise and low vibration. Therefore, it is suitable for the backing pump of diffusion pump, and more suitable for precision instrument matching and laboratory use. For example: mass spectrometry instruments, refrigerator assembly lines, vacuum freeze dryers, etc.
