A pneumatic two-stage pressurized grease injector

Abstract

The invention relates to the technical field of grease pressure, in particular to a pneumatic secondary supercharged grease trap with an aim to mainly solve the problem that greater power is provided by increasing power source when adding grease to large-scale valves or equipment resulting in high investment cost in the prior art. The pneumatic secondary supercharged grease trap comprises a rack, at least one supercharged cylinder and a grease chamber are respectively arranged on the rack, the supercharged cylinders are communicated with the grease chamber to enable the grease chamber for form a first-stage compression chamber, a connecting pipe is arranged on the grease chamber, a pneumatic motor is arranged on the rack, the pneumatic motor is connected with the other end of the connecting pipe to enable the connecting pipe to form a second-stage compression chamber, an injection port is arranged in the connecting pipe, and a switch is arranged in the position of the injection port.

Description

technical field [0001] The invention relates to the technical field of grease pressure, in particular to a pneumatic two-stage pressurized grease injector. Background technique [0002] Grease lubrication is to supply grease to the friction surface of moving mechanical parts to reduce the wear of parts and increase the service life of parts. The key to grease lubrication is to apply the right amount of grease to the friction surface at the right time. The so-called timely application of grease means that the cycle of applying grease to the friction surface should be determined. If the cycle is too long, it will easily cause the lack of lubrication of parts. The so-called proper application of grease means that the amount of grease applied to the friction surface should be appropriate. Too much will easily cause waste, and too little will easily cause the lack of lubrication of parts. [0003] Chinese Patent No.: 95242076.7 discloses a pneumatic grease injection motor for v...

AI Technical Summary

Problems solved by technology

[0007] Therefore, in view of the above-mentioned problems, the present invention provides a pneumatic two-stage pressurized grease injector, which mainly solves the problem that the traditional grease injector in the prior art only undergoes one-stage pressurization before injecting grease. When the equipment is filled with grease, more power is provided by increasing the power source, but it causes the problem of high investment cost
