How to maintain Brass Camlock Coupling?

Brass Camlock Coupling is a quick fluid connection device that uses the eccentric cam compression principle. The core of its maintenance is to ensure the smoothness of the rotating mechanism and the integrity of the sealing interface. Scientific maintenance requires the establishment of preventive maintenance procedures based on the characteristics of brass materials and dynamic sealing requirements.

The cam shaft groove of the brass camlock coupling is prone to accumulate hardened medium residues, which need to be removed with a flexible brush and solvent. When the contact surface of the crescent-shaped claws is worn and dented, it must be replaced as a set to avoid pressure imbalance. The shaft pin is injected with water-resistant grease every quarter to maintain the smooth opening and closing of the operating handle.

Butyl rubber seals should avoid contact with mineral oil-based lubricants to prevent swelling and deformation. During installation, confirm that the seal is fully embedded in the socket, and observe whether a uniform extrusion ring is formed on the outer edge after the cam is closed.

How to protect against humid environments?

The passivation film on the brass surface of the brass camlock coupling should be activated regularly with a weak acid solution to inhibit the development of dezincification corrosion. Insulation sealant is applied to the galvanic corrosion risk area to block the electrolyte passage with stainless steel pipes. When stored for a long time, the inner cavity of the joint is filled with vapor phase rust inhibitor.
