Punch air spring/air bag

Self-sealing is named for its self-sealing without external force. As shown in the figure, when the rubber flexure is reinforced with a fiber layer, the steel (galvanized) waist ring that prevents expansion will be placed in it.
The steel traveler at the end of the cover plate uses the internal pressure of the air to deform the rubber mouth and make close contact with the upper and lower cover plates (galvanized), thereby preventing air leakage.
The upper and lower cover plates are formed by machining.
The air hole is a pipe threaded air intake hole for the installation of the air intake line
Threaded holes for mounting

How to install the upper and lower plates

Gently fit the upper and lower plates with the air spring, and then gradually send in compressed air after height restriction to increase the internal pressure, and the upper and lower plates can be automatically fitted with the air spring to achieve sufficient airtightness. If internal pressure is applied without height restriction, the upper and lower plates will collapse. Therefore, the upper and lower plates must be placed on a device with considerable strength that can limit the height for pressurization. If there are foreign matter, rust, oil stains, etc. on the sealing parts of the air spring and the upper and lower plates, they should be cleaned before operation. In addition, apply some soapy water to the connecting part of the rubber and the upper and lower plates, it will be easier to fit.

How to disassemble the upper and lower panels

Insert a crowbar with a flat front end into the connection between the air bomb and the upper and lower plates, and pry it hard to disassemble it. To avoid prying forcefully in one place, it should be disassembled in several places in order to prevent damage to the air spring.
