High-sealing secondary high-pressure pump

Abstract

The invention relates to an air pump, and discloses a high-sealing secondary high-pressure pump. A reduction gearbox is arranged in front of a motor, a crank shaft is connected with an output shaft ofthe reduction gearbox, one side of a connection rod is connected with the crank shaft, the other side of the connection rod is connected with a primary piston, a primary check valve is arranged at one end of the primary piston, and an air storage chamber is arranged in the middle of the primary piston. The other end of the primary piston is connected with a secondary piston rod in a high-sealingmode, an air hole is formed in the middle of the secondary piston rod, and the other end of the secondary piston rod is connected with a high-pressure piston. A secondary check valve is arranged in asecondary high-pressure piston, a noise-reduction filter and a check valve block are arranged at an air inlet of a primary air cylinder cover, and a cooling system is arranged on the outer side of a secondary air cylinder which is arranged on one side of a high-pressure air cylinder cover. A pressure limiting anti-explosion device is arranged on the other side of the high-pressure air cylinder cover, one end of a high-pressure air pipe is connected with one side of the high-pressure air cylinder cover, and the other end of the high-pressure air pipe is connected to the high-pressure filter. Inthe air pump, the primary air cylinder and the second air cylinder are coaxial in a 180-degree mode, the force in the work process is balanced, the size is small, energy conservation and environmentprotection are achieved, the pressure of output air is high, and the sealing is high.

Description

technical field [0001] The invention relates to an air pump. It specifically relates to a high-seal two-stage high-pressure pump. Background technique [0002] The existing plunger type air pump basically consists of a pump body and a motor installed on the pump body to drive the pump body. As more and more small household appliances use air pumps, the application fields of air pumps are becoming wider and wider. , the output air pressure requirements are getting higher and higher, but the ordinary air pumps currently on the market are obviously difficult to meet the requirements, and the pressure is often insufficient and the sealing is poor when used. Contents of the invention [0003] The object of the present invention is to provide a high-seal two-stage high-pressure pump with high output gas pressure and good sealing performance in view of the defects and deficiencies of the prior art. [0004] In order to achieve the above object, the present invention adopts the ...
