Vacuum pump
First, what is a vacuum pump
Vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical chemical methods to pump the pumped container to obtain vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in an enclosed space. According to the working principle of vacuum pump, vacuum pump can basically be divided into two types, namely gas capture pump and gas transfer pump. It is widely used in metallurgy, chemical, food, electronic coating and other industries. With the development of vacuum applications, the types of vacuum pumps have developed in many varieties, and their pumping speed has increased from a few tenths of a liter per second to hundreds of thousands and millions of liters per second. In order to facilitate use and the needs of various vacuum processes, sometimes various vacuum pumps are combined according to their performance requirements and applied in a unit type.
Second, what are the characteristics of the vacuum pump
- There is a large pumping speed in a wide pressure range
- The rotor has good geometric symmetry, so the vibration is small and the operation is stable. There are gaps between the rotors and between the rotor and the housing, no lubrication, small friction losses, which can greatly reduce the drive power, so as to achieve higher speeds;
- The pump cavity does not need to be sealed and lubricated with oil, which can reduce the pollution of the vacuum system by oil vapor;
- There is no compression in the pump cavity and no exhaust valve. Simple and compact structure, insensitive to dust and water vapor in the pumped gas;
- The compression is relatively low, and the effect on hydrogen extraction is poor;
- The rotor surface is a curved cylinder with a more complex shape, which is difficult to process and inspect.
Vacuum pump is a kind of device that uses physical, chemical and other principles to maintain vacuum, and the effect is good to use. Through the introduction of Chinese brand - Yazlad, I think everyone already knows what the characteristics of the vacuum pump have.
