Description 2-2
Part 7159651_01 E 2012 Nordson Corporation
The feed center controls are designed to accommodate two HDLV transfer
pumps: a reclaim pump to transport over-sprayed powder from the booth
recovery system to the feed center, and a optional bulk feed pump that adds
virgin powder to the system as needed.
Both transfer pumps deliver the powder to the vibratory sieve, where it is
conditioned before delivery to the powder spray guns.
The color change operation is automatic. During a color change,the HD
Hopper cycles through a number of cleaning processes. High-pressure
purge air is pulsed through the powder feed pumps, hoses, and guns to
clean them of powder. This also cleans the sieve section and hopper itself
leaving minimal cleaning from the operator. The reclaim and virgin powder
transfer pumps can be purged manually, as required.
The Spectrum HD feed center requires a remote air extraction system that
provides a constant airflow through the enclosure, preventing powder
escaping into the spray room. The typical extraction system consists of an
afterfilter assembly consisting of an exhaust fan, primary cartridge filters,
pulse valves and controls, and final filters. A rectangular duct connection is
provided at the bottom rear of the feed center enclosure.
