Oil-free dry mechanical vacuum pump, referred to as dry mechanical pump, refers to the pump can start pumping from atmospheric pressure, and can be pumped gas directly into the atmosphere, no oil or other working medium in the pump cavity, and the ultimate pressure of the pump is the same order of magnitude or close to the oil-sealed vacuum pump.
Finally tell you a secret: a foreign well-known equipment manufacturers after 2 years of investigation, recently formally signed a long-term cooperation agreement with us, Hokaido rotary pump will be as a vacuum in its equipment to obtain part, into a new application area.
In the beginning, this pump was used as a blower for internal combustion engines; Later, by inverting the drive, the Roots principle was applied to gas meters. It was not until 1954 that this principle was applied to the field of vacuum pumps.
In the environment of advocating energy conservation and emission reduction, oil-free vacuum pumps are the trend of industry development, especially some new industries, such as semiconductors, lithium batteries, etc., have high requirements for clean environment, and oil-free pumps will be preferred.
In the vacuum pump family, the Roots pump is a bit special, its operation requires the cooperation of the backing pump, why is this? To understand the reason, let's first look at the structural characteristics and performance characteristics of the roots pump.
The main uses of oil rotary vane pumps are metallurgy, machinery, military, electronics, chemical, light industry, petroleum and medicine and other production and scientific research fields.
Reasonable and scientific maintenance of vacuum pumps can effectively extend the life of vacuum pumps and reduce the risks and losses caused by shutdown, shutdown and maintenance.
When purchasing a vacuum pump, the following should be noted:
The importance of technological innovation and research and development to a company cannot be overstood, especially for technology-oriented products such as vacuum pumps.
In the production process of these products, vacuum equipment is required, and due to the complex and demanding production process of the fine chemical industry, vacuum units with more powerful functions are often used.
Vacuum equipment such as Rotary Vane Vacuum Pumps, Claw Vacuum Pumps, Water Ring Vacuum Pumps and Vacuum Units from China Hokaido Factory are commonly used in vacuum depositors.
At this point, the company has completed the processing of three certificates, namely: medical device manufacturing enterprise license, medical device business license, and medical device registration certificate.
Lithium batteries have a wide range of applications and a large amount of applications, and it has become particularly important to do a good job in energy conservation and emission reduction from the source in the production process.
The use of Roots vacuum pump must be equipped with a backing pump and is not used alone.
Vacuum pump (unit) used in plasma cleaning machine, for inquiries and customization, please contact Chinese Hokaido vacuum pump supplier.
