At present, there are few domestic oil free scroll vacuum pump manufacturers, and the market is basically imported oil-free vacuum pump products. It has the advantages of simple structure, simple operation, convenient protection and environmental pollution. The oil-free vacuum pump has good durability. It is a vacuum pumping, contraction and dual-purpose vacuum pump. It is a basic equipment which is widely used to obtain vacuum.
oil free scroll vacuum pump is a kind of mechanical vacuum pump which can operate without any oil lubrication. The oil-free vacuum pump has good durability. It is a vacuum pumping, compression and dual-purpose vacuum pump. It is a basic equipment with a wide range of applications to obtain vacuum. Compared with the oil pump, the oil-free vacuum pump has the advantages of low vacuum degree, small air volume, small size, easy installation, simple maintenance, convenient movement, no oil smoke and environmental pollution, especially in the high-demand scientific research, medical beauty and other industries. It is also one of the most common equipment in the laboratory.
It is necessary to check and determine the vacuum degree of oil-free vacuum pump required by each process. Because each process has its own conventional vacuum degree planning, it is necessary to carefully study and determine the vacuum degree. Secondly, check the type and volume of air extraction required by the judgment process of oil-free vacuum pump. Because if the type of pumped gas and the liquid in the pump burst, the pump system will be polluted.
At the same time, it is necessary to determine the appropriate exhaust time and the amount of gas during the extraction process. Then, the ultimate vacuum degree of the vacuum pump is checked on the basis of determining the vacuum degree required by the oil-free vacuum pump process, because the ultimate vacuum degree of the vacuum pump selects the best operating vacuum degree of the system. Generally speaking, the limiting vacuum degree of the system is 20% lower than the operating vacuum degree of the system, and 50% lower than the limiting vacuum degree of the front stage pump.
Finally, check and determine the time required to reach the required vacuum, the flow resistance and leakage of the vacuum pipeline. In consideration of the air extraction rate required to connect the vacuum under certain process requirements after reaching the required vacuum degree, the oil-free vacuum pump uses the vacuum suction on the active packaging line to open the bag and load.
