Fuseless Coordinated Motor and Circuit Protection – This control system was designed
to comply with the National Electric Code as a “multi-motor and other loads” branch
circuit. The control elements in this system have minimum withstand rating of 50 kA
when the branch circuit providing power is protected with a listed fuse or breaker of
equal or greater rating.
3.8 Description and Function - Ventilation System
A controlled flow of air must pass through the surface preparation equipment and the 6-
54 Dust Collector during normal operation for the reasons listed below:
•
Cools surface preparation equipment components.
•
Helps remove dust from work surface.
•
Transports dust and contaminants to dust collector.
Ventilation air must follow a designed path through the machine(s). Any irregularities in
the path can affect the performance of the system. The air sequence follows:
1. Air enters the area around the seals of the surface preparation equipment at a high
velocity and helps sweep dust from the work surface.
2. This air traverses up the through the equipment housing and exits through the outlet.
The air movement through the equipment housing aids in keeping the equipment
housing and internal components cool.
3. The hose delivers the contaminated air to the dust collector where the air is filtered
and returned to the atmosphere.
The ventilation system should be monitored on a regular basis. Bad or improper
ventilation can lead to poor component life and premature wear on a number of
ventilation related items on the equipment. Some of the more important areas to
monitor, relative to the ventilation system, are:
•
The skirts around the blast housing should be kept in good repair.
•
The seals around the separator lid should be checked regularly.
•
The hose connections to the blast unit and the 6-54 Dust Collector should be
tight and held in place with metal clamps.
•
The hose should be kept in good repair. Flattened spots, holes and wear
spots should be corrected immediately. Replace hose if necessary.
