Application of Vacuum Unit in Handicrafts
Vacuum units have been widely used in production and scientific research departments such as metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum and medicine. It can be used alone or as a backing pump for other high vacuum pumps or ultra-high vacuum pumps.
The composite sewage treatment process is a sewage treatment process developed after the intensive use of two or more different sewage treatment methods. For example, the typical composite sewage treatment process in our country, the diversion biological aeration filter, is based on the traditional aeration On the basis of the biological filter, fully learn from the downward flow biological aerated filter method, the upward flow biological aerated filter method, the contact oxidation method, the biofilm method, the artificial quick filtration method, the sedimentation separation method, and the pumpless sludge Eight design techniques such as the backflow method and the fast water filtration method, and the sewage treatment process and new technology developed by the secondary or tertiary sewage treatment process are one of them.
Application characteristics of vacuum unit in crafts:
- Small size, light weight, low noise;
- Equipped with a gas ballast valve, which can extract a small amount of water vapor; in the ambient temperature range of 5 degrees Celsius to 40 degrees Celsius, the air inlet pressure is less than 1.3X103 Pa, allowing long-term continuous operation, and the relative humidity of the pumped gas is greater than 100 degrees. At 90/90, the gas ballast valve should be opened. 3. Equipped with automatic anti-return oil check valve, easy to start;
- The air inlet should not operate continuously and unblocked for more than one minute;
- It is not suitable for the removal of gases that are corrosive to metals, chemically react to pump oil, and contain particulate dust, as well as gases that contain excessive oxygen, are explosive, and are toxic.
