Gas pressure chamber with protection function

Abstract

The invention discloses a gas pressure chamber with a protection function. The gas pressure chamber is applied to an oil sample feeding system of an automatic oil particle counter and comprises a barrel body, an upper sealing cover and a lower sealing cover. The barrel body is wrapped with a metal protection layer, the upper sealing cover and the lower sealing cover seal and cover the barrel body and the metal protection layer, an outer sheath is arranged outside the metal protection layer, a buffer gap is formed between the metal protection layer and the outer sheath, a pressure releasing slit is formed between the outer sheath and the upper sealing cover, an explosion-proof membrane can be further pasted outside the barrel body, and the metal protection layer is attached to the explosion-proof membrane. The gas pressure chamber with the protection function can effectively prevent debris of the glass barrel body from splashing outwards, has multiple functions, improves explosion-proof grade of the barrel body and improves using safety of the automatic oil particle counter.

Description

technical field [0001] The invention relates to a gas pressure chamber, in particular to a gas pressure chamber with protection function applied in an oil liquid sampling system of an automatic oil particle counter. Background technique [0002] Oil pollution, especially solid particle pollution, is the main cause of mechanical hydraulic system failure and premature wear and damage of hydraulic components. Using the oil pollution detection method and device, the pollution state of solid particles in the hydraulic system can be evaluated by detecting the size / quantity distribution of solid particles in the hydraulic oil. Since the detection method and device do not need to decompose and disassemble the hydraulic system, it can be timely It is widely used to predict the failure of mechanical hydraulic system. [0003] At present, the commonly used oil pollution detection device is an automatic oil particle counter, which includes an oil sampling system, a particle counting sy...

Problems solved by technology

[0004] In order to facilitate the observation of the sampling situation of the oil sample in the sample cup in the gas pressure chamber, the cylinder body of the gas pressure chamber is generally made of pressure-resistant glass. Although the observation is convenient, when the pressure in the pressure chamber is too high and the pressure chamber explodes, The glass cylinder is broken, and the splashed fragments are likely to cause injury to the operator, posing a safety hazard
