Apparatus for marking insulated electrical conductors

摘要

A straining filter which has an opening at the highest point of the filter dome is inserted in the pipe which supplies the spray nozzles and is further connected to the opening of an additional pipe. Spray nozzles acted on by an electrical field supply colored marking rings to a cable or wire. The material to be sprayed is held in the storage tank and is transferred by a gear pump through a buffer vessel and into a pipe. Inserted in the pipe is a double walled straining filter whose outlet is connected to a pipe running to the spray nozzles, with a valve and a pressure gauge inserted between the straining filter and each spray nozzle. Any gas bubbles introduced into the straining filter with the color material gather at the highest point of the filter dome and are carried away therefrom.
