Problems solved by technology

The air-tightness detection device in the above-mentioned patent has the following deficiencies: put it into the water tank to observe whether there are bubbles to detect the air-tightness. Constantly adding anti-rust water will increase follow-up costs. When putting into the water tank, only one oil tank can be put in for observation at a time, and one person can only observe one oil tank, which is inefficient and increases labor costs

Abstract

The invention discloses an oil cylinder airtightness detection device, and relates to the technical field of oil cylinder airtightness detection devices. In order to improved the detection efficiencyand reliability, the device specifically comprises a workbench and two symmetrically-installed gas path mechanisms, and six pressure gauges are fixed to the outer wall at the top of the workbench through screws, and each gas path mechanism comprises an oil cylinder main gas pipe and three oil cylinder gas supply pipes separately connected to an oil cylinder to be tested. The two oil cylinder maingas pipes are fixed to the outer walls of the two symmetrical sides of the workbench through buckles respectively, and one end of each oil cylinder main gas pipe is connected to an external gas circuit system; the other end of the oil cylinder main air pipe is connected with a first pressure reducing valve, and the first pressure reducing valve is connected with a first electromagnetic valve through an air pipe. According to a detection chamber, a data conclusion can be accurately obtained, the air pressure value is adjusted according to different oil cylinder requirements, different sealing performance requirements are obtained, data can be conveniently recorded, the problem of low efficiency is solved, and the probability of errors caused by manual judgment is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of an oil cylinder air tightness detection device, in particular to an oil cylinder air tightness detection device. Background technique [0002] Nowadays, hydraulic cylinders are used more and more widely, and they are involved in almost all fields, especially for road machinery and construction machinery. With the vigorous development of infrastructure projects in our country, the market demand for various road machinery and equipment has increased, and the demand for hydraulic cylinders has also increased, such as loader cylinders, pile foundation cylinders, excavator cylinders, dump truck lift cylinders, etc. At the same time, the requirements for cylinders It is also getting higher and higher, entering the market of survival of the fittest. [0003] After retrieval, the Chinese patent application number is CN201821978994.4, which discloses an oil cylinder air tightness detection device, which relates t...
