Nine Problems When Install The Key Type Air Shaft

The key-type air expansion shaft can move and fix the paper tube at any position on the shaft surface by the action of inflation and deflation. Therefore, it has been widely used, so let us know about the installation of the key-type air shaft:

1. Familiar with the construction drawings and site conditions, and formulate detailed construction plans.

2, To be proficient in the way of laying, installation, methods and skills of the key-type air shaft, understand the precautions in the construction, such as the bending radius of the gas-up shaft, the arrangement of the laying, how to enter and exit the distribution box, cabinet, how to pay attention to eliminating eddy currents.

3. Familiar with the accessories of the air expansion shaft, and the installation and use methods of each accessory.

4. After the pneumatic shaft is laid, if there is no intermediate joint, the terminal can be directly used. If there is an intermediate joint, the intermediate joint should be made first, otherwise the trouble of checking the phase will be increased.

5. Understand the special tools required for the installation of the key gas-increasing shaft and master the use method.

6. During the laying process of the inflatable shaft, or after laying and installing, it is necessary to strictly prohibit the electric welding faucet wire from being dragged or collided on the key gas rising axis.

7. Fully understand the structure, performance and characteristics of the expanding shaft, and understand the type, specification, type and adaptation of the gas-increasing shaft.

8. The copper sheath of the core shaft can be used for grounding and must be grounded.

9. In the process of laying and installing, the insulation of the key type gas rising shaft should be tested diligently, and the problem should be dealt with in time.
