Embodiment 1

[0022] Such as figure 1 , figure 2 As shown, a dual-pressure compressor includes: a first cylinder 1, a second cylinder 2 and a motor 3, wherein the first cylinder 1 is a compression cylinder forming a positive pressure, and the second cylinder 2 is a compression cylinder forming a positive pressure. Negative pressure vacuum cylinder, the motor 3 drives the first piston 11 in the first cylinder 1 and the second piston 21 in the second cylinder 2 to reciprocate through the transmission mechanism 4, which is convenient for providing gas and vacuuming the equipment at the same time . Preferably, the first cylinder 1 and the second cylinder 2 are arranged oppositely, the motor is arranged at the interface of the first cylinder 1 and the second cylinder 2, and the shape of the entire compressor is "T".

[0023] Wherein, the first cylinder 1 includes: a first intake valve, a first exhaust valve and a first piston 11 located in the first cylinder, the first intake valve communicat...

Embodiment 2

[0028] The structure of a dual-pressure compressor provided in this implementation is basically the same as that of Embodiment 1, the difference lies in the design of the transmission mechanism.

[0029] Such as image 3 As shown, a dual-pressure compressor transmission mechanism provided in this embodiment includes: a first rotating shaft 45 connected with a motor and having a first gear 44, and a second rotating shaft 45 having a second gear 46 arranged on one side of the first rotating shaft 45. The rotating shaft 47 is arranged on the other side of the first rotating shaft 45 , the third rotating shaft 49 having the third gear 48 , and the eccentric wheel 42 fixedly connected with the second rotating shaft 47 and the third rotating shaft 49 .

[0030] In this embodiment, the fixing method of the first gear 44 and the first rotating shaft 45 is screw riveting, the second gear 46 and the second rotating shaft 47 are integrally formed, and the third gear 48 and the third rota...

Abstract

The invention provides a dual-pressure compressor. The dual-pressure compressor comprises a first air cylinder (1), a second air cylinder (2) and a motor (3), wherein the first air cylinder (1) is a compression air cylinder; the second air cylinder (2) is a vacuum air cylinder; the motor (3) drives a first piston (11) inside the first air cylinder (1) and a second piston (21) inside the second air cylinder (2) to move in a reciprocating manner to form a positive pressure inside the first air cylinder (1) and a negative pressure inside the second air cylinder (2) respectively, thereby conveniently providing and removing gas for the device. The dual-pressure compressor is integrated with an air compressor and a vacuum pump, so that a vacuum can be generated while air is compressed, and the dual-pressure compressor is simple in structure and good in practicality.

Description

technical field [0001] The invention relates to the design field of reciprocating piston compressors, in particular to a dual-pressure compressor. Background technique [0002] As a general equipment, air compressor is widely used in steel, electric power, metallurgy, shipbuilding, textile, electronics, chemical industry, petroleum, mining, light industry, machinery manufacturing, food and medicine and other fields. At present, the existing air compressors on the market can only compress air; vacuum pumps can only be used for vacuuming. For some applications that require both positive pressure and negative pressure air sources, both air compressors and vacuum pumps must be equipped with two air power sources, which makes the system complex and costly. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to develop a dual-pressure compressor, which combines the two structures of the vacuum pump and the air...
