Key Bar Type Air Expansion Shaft (air Rising Shaft) Air Leakage Inspection And Maintenance

Key strip type air expansion shaft (air rising shaft) air leakage inspection and maintenance method
First take the process of dismantling the inflation shaft (gas rise shaft)
Before disassembling, first look at the structural diagram of the key bar type air expansion axis (air expansion axis), and then manually operate, first press the steel head of the inflation shaft (air rising shaft) aeration nozzle, and the air expansion shaft ( The compressed air in the gas riser shaft is discharged, and then the aeration nozzle is removed. Use a wire with a diameter of 1-1.2 mm to pierce the small hole on the key strip along the circumferential direction of the inflation axis (air rising axis), and set it in the same circumferential direction; tie all the key strips firmly. Avoid pulling out the air bag. The rubber strip can also be easily installed in the aluminum alloy roller. The set screw (M6 hexagonal screw) and the positioning sleeve of the fixed end of the aluminum alloy roller and the inflation shaft (air rising shaft) are taken out.
It is necessary to machine a screw for the pin puller, and to clamp the air expansion shaft (air rising shaft) on the lathe, usually like the touch between the inflatable end of the key bar type air expansion shaft (air rising shaft) and the aluminum alloy roller The surface will be coated with sealant. You should first use a gas torch and heat it first. When heating, other parts should be cooled to avoid deformation of the aluminum alloy roll. After the sealant is softened, the end is pulled again. Since the airbag is connected with the inflation end, the airbag can be easily pulled out.

Analysis and treatment of the cause of the inflation axis (gas rise axis)
Air expansion shaft (gas rise shaft) air leakage at the inflation nozzle: check the inflation nozzle if the inflation nozzle is normal. Just strengthen the seal at the touch surface of the inflation nozzle and the inflation end, the inflation nozzle is not normal, and the inflation nozzle should be replaced.
Air leakage shaft (gas rise shaft) other parts of the air leak: check the airbag surface for some damage, if you need, you need to replace the airbag. In addition, it is to check whether there is air leakage at the airbag and the inflation end, and if there is a leak, it should strengthen its seal.
The inflation shaft (air up axis) key bar is detached: check whether the key bar and the key bar holder are combined and normal, and the base is damaged. Repair the base and fasten the key strip to the base.

Installation of the inflation shaft (gas rise shaft) process
A special glass glue is selected on the airbag connector of the inflated end to be modified, and the airbag connector is placed on the airbag. The airbag is then bundled onto the joint with a wire of 1-1.5 mm in diameter. Take care (pay attention to the binding and avoid leaks). At the end of the airbag, the airbag clamping sleeve is set, and the special Borui rubber is applied to the gas-filled tensioning head. Put the tight head into the airbag. The capsule is allowed to stand for a while, waiting for the glass glue to solidify. Install the inflation nozzle onto the inflation tip.
The air bag is filled with compressed air by inflating and aligning the inflator. Keep in mind that the airbag is not bound by external pressure at this moment, and the inflation should not be excessive; to prevent damage to the airbag. Put the inflated tip together with the gas flag into the water phase to see if the aeration nozzle and the balloon are leaking.

After confirming that the aeration nozzle and the airbag are sealed, the inflation shaft (air expansion shaft) can be installed. Apply anaerobic adhesive to the touch surface of the fixed end and the aluminum alloy roller, and then align the end with the positioning hole of the aluminum alloy roller. There is a steel number at the contact point between the fixed end and the inflatable end and the aluminum alloy roller. Be careful not to misplace the two ends, and then press the fixed end to the aluminum alloy roller. Install the positioning sleeve, tighten the set screw, and tighten the countersunk head socket head cap screws.

After applying the soft rubber on the touch surface of the inflatable end and the aluminum alloy guide roller, together with the airbag, the positioning sleeve and the positioning screw are fastened together with the airbag, and the hexagon socket head cap screw is fastened.
Remove the wire from the key strip. Inflate and deflate the inflation shaft (gas rise shaft) to ensure that the health bars can float up and down. Then, the inflation shaft (gas rising shaft) is pierced into the paper core hole of the paper, and the compressed air is filled, and after standing for a period of time, if the inflation shaft (gas rising shaft) is not leaking or falling, etc., It is clarified that the inflation axis (gas rise axis) is now in normal use.
