What is a vacuum suction cup lifting device?
2018-02-05
A vacuum suction cup lifting device is a type of vacuum lifting equipment that can lift large objects such as steel plates, glass, aluminum coils, and stone slabs. It consists of suction cups and other main components. Many people also refer to vacuum suction cup lifting devices as suction cups or vacuum cups, because the suction cups are more noticeable, and the material used for the suction cups is very important.
What types of vacuum pumps are there?
2019-05-05
Vacuum pumps are mainly classified according to their working principles into reciprocating vacuum pumps, water ring vacuum pumps, rotary vane mechanical pumps, Roots vacuum pumps, turbo molecular pumps, dry vacuum pumps, diffusion pumps, and cryogenic pumps. The vacuum pump section mainly discusses the selection of vacuum pumps and vacuum pumping units, the working principles of vacuum pumps, and other professional knowledge.
How to properly maintain a vacuum pump, and what key points should be noted?
1. Regularly check the oil level; if it does not meet the requirements, it must be adjusted to comply. When the vacuum pump is running, the oil level should be at the center of the oil mark. 2. Regularly check the oil quality; if the oil is found to be deteriorated, it should be replaced with new oil in a timely manner to ensure the vacuum pump operates normally. 3. The oil change period should be determined by the user based on actual usage conditions and whether performance requirements can be met. Generally, for a new vacuum pump, when extracting clean and dry gases, it is recommended to change the vacuum pump oil after about 100 hours of operation. Once no black metal powder is visible in the oil, the oil change period can be appropriately extended. 4. Generally, the vacuum pump operates for 20...
Rotary vane vacuum pump working principle demonstration diagram
2020-06-21
The rotary vane vacuum pump (referred to as the rotary vane pump) is an oil-sealed mechanical vacuum pump. Its working pressure range is 101325 to 1.33×10-2 (Pa), which classifies it as a low vacuum pump. It can be used independently or as a forepump for other high vacuum or ultra-high vacuum pumps. It has been widely used in metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum, and pharmaceutical production and research departments. The rotary vane pump can remove dry gases from sealed containers, and if equipped with a gas ballast device, it can also remove a certain amount of condensable gases. However, it is not suitable for removing gases with high oxygen content, corrosive to metals, or that can affect the pump oil.
