Vacuum pump in chemical industry
Most mechanical vacuum pumps used in vacuum industry use water, oil or other polymers as working media. With the development of science and technology and the expansion of the application field of vacuum pumps, two urgent problems have arisen in the original mechanical vacuum pumps and the pumping system consisting of them. One is that the working medium of pumps pollutes the pumped containers, which in many cases affects the quality and quantity of products and increases the cost of equipment maintenance. Secondly, it is difficult to recover the gas pumped into the vacuum pump in some process, and the medium in the pump deteriorates.
Dry screw oil-free vacuum pump is favored by more and more manufacturers because of its compact structure, no friction of the original parts of the suction chamber, long life, low energy consumption and no oil pollution. It has incomparable advantages in the chemical industry, gradually replacing the traditional mechanical vacuum pump. The recovery of extremely easy chemical gases has greatly saved the production cost and reduced the environmental protection pressure of enterprises.
Dry screw vacuum pump is a high-tech product. It is mainly used in high-purity vacuum process. It has high vacuum degree and can adapt to harsh conditions. It has the ability to extract condensable and particulate gas. It is especially suitable for electronic, chemical and biomedical fields.
The screw rotor, which is the core part of the screw vacuum pump, is designed and solved by using three-dimensional surface mathematical model. The solid of the model is processed on the five-coordinate CNC equipment. It has high precision, reliable quality and stable performance, and ensures the long-term trouble-free operation of the product.
This product has independent innovation, strong market competitiveness in product quality and price. It can replace imported products in a wide range and has a large market demand. It will completely replace the current technology in more than 100 fields, such as chemical industry, metallurgy, electronics, petroleum, aerospace, tools, paper making, packaging, food, medicine, medical devices, and information engineering, bioengineering, microelectronics, etc. Low volume vacuum equipment.
