Fig. 20: Adjustment by flow meters
During adjustment all batteries must have the same pressure (see also 5.1.4.). In order to insure a precise
adjustment. Also make sure that the flow limiters are mounted. Before adjustment all adjustment screws of the
vacuum regulators have to be unscrewed until the screw head extends into the housing approx. 3 mm.
Procedure:
• Open all cylinders of the battery
• Switch on ejector
• Completely open the adjustment valves of all flow meters mounted for adjustment.
• Reduce flow rate of central flow meter to approx. 200 g/h for every connected vacuum regulator.
• Set all flow meters to the same value by turning the screws of the vacuum regulators. Screwing in cor
-
responds to a higher rate whilst unscrewing means a lower flow rate.
IMPORTANT!
However, the vacuum regulators adjusted this way are set to the same value within one cylinder battery, but
are not identical to another cylinder battery adjusted in the same way. Therefore it is not permitted to exchange
single units of the cylinder batteries. In that case a readjustment is absolutely necessary.
