Five steps of rocking joint crimping
1、 Crimping of rocking joint:
1) Pipe cutting: if the pipe is in a system, re cutting is required before the pipe is connected again, and the pipe cutter shall be kept in good condition. This is to ensure that there is no burr on the outer diameter of the tube, and the feed should not be too fast.
2) In order to clean the pipe ends, the pipe ends must be cleaned. Proper tools (fine and fine phase sandpaper, etc.) must be selected to remove pigment and oil. In order to prevent the longitudinal groove of the pipe, the pipe must be rotated instead of single longitudinal cleaning when cleaning the pipe end.
3) Note: too much liquid drop will be added to the end of the lock ring pipe, otherwise, too much liquid will be drawn out from the end of the lock ring pipe. If it is a capillary tube, be sure to prevent the flow of rocking gum into the tube and harden. Insert the copper tube into the rocking joint again until it stops, and turn the connector 360. To make the distribution of roxobin evenly.
When there is no inner stop, in order to prevent the rocking liquid from entering the capillary tube and causing capillary blockage, the capillary tube should be inserted into the rocking reducer joint, so that the capillary can extend 20 mm out of the other end of the joint, and the other end should be bent slightly as a mark. Pull out some copper tube, drop the liquid, pull out the capillary tube 1cm, drop a drop of rocking liquid.
4) The crimp connection pipe must be inserted into the manufacturing end of the rocking joint and rotated 360 ° so that the rocking glue is evenly distributed. Use the manual installation tool (rocking pliers) to make the lockring pliers fully locked in the jaw. During crimping, the fixing arm of lockring pliers shall be kept still, and the ratchet handle shall be repeatedly pulled to make the rocking joint press to the middle until the end stop, and keep it for 4min.
5) Other types of pipeline connection: for the extension of the process pipe of the compressor, after the application of the rocking glue, use the rocking socket to cover it, and knock the socket with a wooden hammer to fix it.
