The domestic manufacturers of molecular pump stability is not ideal, the price of foreign molecular pump is a lot of consumers can not afford, so the choice of vacuum pumps in the domestic industrial production or the choice of diffusion pump. Only in some high-end industries like the semiconductor industry and scientific research units will use the molecular pump. So to know more about the advantages and disadvantages of diffusion pumps is crucial to the use and development of diffusion pumps. Diffusion pump diffusion pump advantages: 1, the general structure of the oil diffusion pump to improve, such as reducing the return of oil vapor, plus points é• device, a reasonable allocation of heating power, nozzle angle to improve the design, with the oil cap, baffle or Cold trap, adsorption trap, etc., can greatly improve the performance of the diffusion pump, the ultimate vacuum can achieve lower pressure; 2, simple maintenance; 3, low cost; 4, not easy to fail; Need cooling water, the switch must wait; 2, easily lead to sample room pollution; 3, if the pressure generated by the foreline pump is higher than the maximum back pressure, the diffusion pump can not work properly. Diffusion pump than on the molecular pump to switch on and off time should be long on the ten minutes, the need for water cooling system, but available vacuum degree, but to an order of magnitude higher. Understand the advantages and disadvantages of a product, for a more reasonable use of this product has a multiplier effect, diffusion pump has its advantages, but it also has shortcomings, but if you can continue to improve its shortcomings and optimize its advantages, for Further enhancements of products have incalculable effects. This should also become a future research diffusion pump in the direction of professionals should pay attention to this research.
