Abstract

The invention discloses a vacuum pump which comprises a pump body. The vacuum pump is characterized in that the pump body is fixed on a motor base, a top cover is arranged at one end of the pump body and on the inner wall of the pump body, an end cover is arranged on the outer side of the top cover and on the outer wall of the pump body, and a piston component is arranged on the inner wall of the pump body and connected with a motor output shaft arranged at the other end of the pump body; the piston component and the motor output shaft are connected through a movable connecting rod; the movable connecting rod, the piston component and the motor output shaft are connected through a movable connecting shaft; the motor output shaft is connected with a motor fixed on the motor base; and the piston component comprises a piston body and a piston ring which is arranged on the periphery of the piston body, a groove is arranged close to the top cover end on the piston body, and a sealing valve is arranged between the top cover and the end cover. The vacuum pump has the advantages of being simple in structure, small in noise, reliable and stable in vacuum performance, high in operation efficiency, low in cost and convenient to mount, dismount and maintain.

Description

technical field [0001] The invention relates to the field of pumps, in particular to a vacuum pump. Background technique [0002] The vacuum pump is a rotary variable displacement vacuum pump. It can be used in a wide pressure range with a backing pump. It has a large pumping speed and is insensitive to dust and water vapor in the pumped gas. Vacuum pumps are widely used in plastic machinery, pesticide chemical industry, dye chemical industry, brick and tile machinery, low temperature equipment, papermaking machinery, pharmaceutical chemical industry, food machinery, industrial electric furnace, electronics industry, vacuum equipment, chemical fertilizer, metallurgy, petroleum, mining, foundation treatment and other fields . The vacuum pump in the prior art has disadvantages such as complex structure, high noise, small and stable vacuum performance, low working efficiency, high cost, and inconvenient installation and maintenance. [0003] Therefore, there is an urgent need...
