Pipeline air spring using steps
1, before use: first connect the air spring of the pipeline with the inflatable equipment accessories, and do a leak test. Put the filled pipe air spring into the basin filled with water and hold it down to see if there are bubbles. No bubbles can be used.
2, use: the pipe air spring is fully into the pipe, the pipe air spring nozzle with pipe, pressure gauge, air pump and other inflating tools connected, and then in accordance with the scale on the pressure gauge to inflate. To check whether the silt in the pipeline is clean, the inner wall must be smooth, there should be no burr, otherwise it will puncture the air bag.
3, after use: open the valve of the pipe air spring, slowly deflate, and then pull out the pipe air spring vertically. Pay attention not to be pierced by something near the pipe air spring and affect the next use.
