The structure of the vacuum pump

2022-01-10

The vacuum pump is a product with a large quantity and a wide range, with a large output and a low output value, but it is indeed a basic product that directly affects the performance and quality of the complete set of vacuum equipment. The market for vacuum pumps changes dynamically according to the needs of users. The main driving force for the market growth is the rapid development of the semiconductor industry and the increasing application of dry pumps and molecular pumps.

At present, the annual sales of the vacuum pump market is about 2 billion US dollars, and the annual growth rate is about 7%.

There are many manufacturers of vacuum pumps in my country, and the annual sales of all vacuum pumps are about 150 million yuan, which is only equivalent to the annual sales of vacuum pumps of a company in the United States. Through the analysis of the vacuum pump market, we can see that the market and application fields of various vacuum pumps are constantly changing and developing. my country's vacuum pump manufacturing industry has a long history and a solid foundation. Domestic vacuum pumps have been applied and verified in various fields. Some pumps are also exported to foreign countries, which have been recognized and praised by foreign users. It should be said that my country's vacuum pump manufacturing industry is at home and abroad. The market still has huge room for development.

The blister machine is a machine that absorbs the heated and plasticized PVC, PE, PP, PET, HIPS and other thermoplastic plastic coils into various shapes of packaging boxes, boxes and other products. Using the vacuum suction generated by the vacuum pump, the heated and softened PVC, PET and other thermoplastic plastic sheets are blistered into various shapes of vacuum covers, blister trays, blister shells, etc.

Precautions for vacuum pump disassembly and cleaning for vacuum pump maintenance

A vacuum pump is a device that uses various methods to generate, improve and maintain a vacuum in a closed space. A vacuum pump can be defined as a device or device that uses mechanical, physical, chemical or physical-chemical methods to pump the container to obtain a vacuum. Any pump that uses mechanical motion (rolling or sliding) to obtain vacuum is called a mechanical vacuum pump. After a period of use, the vacuum pump needs maintenance, and cleaning the vacuum pump is one of the things that needs to be done. Some vacuum pump users ask a question, what are the precautions for vacuum pump disassembly and cleaning for vacuum pump maintenance?

Features of vacuum pump

(1) Larger pumping speed in a wider pressure range;(2) 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 rotors and the casing, no lubrication is required, and the friction loss is small, which can greatly reduce the driving power, so that a higher speed can be achieved;(3) The pump cavity does not need to be sealed and lubricated with oil, which can reduce the pollution of oil vapor to the vacuum system; (4) There is no compression and no exhaust valve in the pump chamber. Simple and compact structure, insensitive to dust and water vapor in the pumped gas; (5) The compression ratio is low, and the effect of hydrogen pumping is poor; (6) The surface of the rotor is a curved cylinder with a complex shape, which is difficult to process and inspect.
