Before installing the ferrule fittings of the hydraulic system, take a look at the parameters and technical data and the re-preparation tool installation.
U-shaped pipe clamp assembly
The first step of the U-shaped pipe clamp is to install the important part. If the direct installation will affect the reliability of the seal, then you can first test the small diameter pipe joint on the vise. Generally, some pre-installation is required. Device.
The specific implementation steps are as follows:
First, saw a section of seamless steel pipe of suitable length.
Second, the nut and the card are placed in the seamless steel pipe. At this time, pay attention to the direction of the nut and the ferrule. Be careful not to install it.
3. Apply mechanical lubricant to the thread and the ferrule on the pre-assembled joint, insert the tube into the joint body, insert the seamless steel tube to the bottom, and hold the tool to tighten the nut. If the seamless steel pipe is not inserted into the bottom, it will cause oil leakage.
4. Tighten the nut to the ferrule and then catch the seamless steel tube. When the turning point is reached, the torque can be tightened. After feeling the pressure point, tighten the nut to tighten it 1 to 2 turns.
5. Remove the fittings of the fittings and check how the inserts of the ferrules are inserted. The protruding strips must fill the ferrule end space. The ferrule can be rotated slightly by 1/2 turn, but it cannot be moved axially.
Sixth, the final installation is completed. After the installation, the joint body and the thread are coated with mechanical lubricating oil. You can test the tightening force of the installation. Try to tighten the 1/2 turn first. If there is no loose space, it is OK.
