Repair of water-cooled Condensers and Receivers

Weld-shell capacitor can be cut. New water coil can be fitted and shell rewelded. However, this is only done in exceptional cases, because the pressure receptacles shall be made under well-controlled conditions. Repairs must be completed pressure vessel certified welders. After a repair ship must be tested twice the working pressure.

Liquid receivers in the most commercial systems serve as a refrigerant for storage of cylinders. They, as a rule, are of all-welded steel shell. Shell coil condenser and also develops a leak. (This type of condenser with water coil built into the liquid receiver.) There is a corrosive effect of water and refrigerant under certain conditions. In the end, copper pipes are used for transportation of water can be oxidised. Leaking tube allows the refrigerant from the system in the cooling water. This type of leakage can be found by checking the refrigerant into the sewer. Leakage sometimes occur at the joints, where wrater-cooling coil gives liquid receiver. Such damage can be due to abuse or violence. In this case, the condenser should be replaced.

If new parts can be found, quite satisfactory repair can be done as follows:

1. Water tubeif corroded in liquid receivermust be removed,
2. Liquid receiver must be installed on a lathe. At the end of the receiver should be cut. This allows you to delete the old water coil and putting in a new one. Replacement of the block must have the same length tubes, as he retired. Otherwise, the capacitance of the capacitor will changcd. New' coil usually made by winding on the drum is mounted on a lathe. Tube, and then placed in the liquid receiver and brazed joints.
3. After the interior to be thoroughly cleaned, the end can be replaced and welded.
