Abstract
The disclosure relates to a paint supply system for a coating installation (e.g. painting installation) comprising a ring line for circulation of a coating agent, a ring line tapping point in the ring line for extraction of the coating agent from the ring line, a consumer and a tap line leading from the ring line tapping point to the consumer. The disclosure provides a device for alternately moving the coating agent forward and backward in the tap line to avoid settling of the coating agent in the tap line.
Claims17
A paint supply system for a coating installation comprising:
- a) a ring line adapted for circulation of a coating agent,
- b) a ring line tapping point in the ring line adapted for extracting the coating agent from the ring line,
- c) a consumer, which is supplied with the coating agent,
- d) a tap line leading from the ring line tapping point to the consumer,
- e) a valve arrangement, and
- f) means for alternately moving the coating agent forward and backward in the tap line in order to avoid settling of the coating agent in the tap line, wherein the means for alternately moving the coating agent forward and backward in the tap line includes at least one pig line which contains a displaceable pig and leads from the valve arrangement to a pig station, and the pig station moves the displaceable pig for returning the coating agent from the at least one pig line into the tap line from the pig station in a direction of the valve arrangement.
A paint supply system for a coating installation comprising:
- a) a ring line adapted for circulation of a coating agent,
- b) a ring line tapping point in the ring line adapted for extracting the coating agent from the ring line,
- c) a tap line leading from the ring line tapping point to a closed end,
- d) a consumer connected to the tap line between the ring line tapping point and the closed end, the consumer supplied with the coating agent,
- e) means for alternately moving the coating agent forward and backward in the tap line in order to avoid settling of the coating agent in the tap line, the means for alternately moving the coating agent forward and backward in the tap line including a cushion of a compressible medium at the closed end of the tap line, the cushion of the compressible medium reflecting pressure shocks from the tap line and thereby alternately moves the coating agent standing in the tap line forwards and backwards.
