Lubrication Equipment AWM AWD EX: How to obtain the mist generating pressure differential if the flow rate obtained in q above is 35m3/min and the line pressure (primary pressure P1) is 0.7MPa : Extend horizontally from the point at which the flow rate is 35m3/min to obtain the point that intersects with P1 = 0.7MPa.
The inlet pressure obtained in the flow characteristic graph of silencer indicates the pressure (P1) prior to silencer. (Refer to the diagram below.)

When the inlet pressure (P1) is shut off and released, the check valve w opens and the pressure in the diaphragm chamber q is released into the inlet side (Figure 2). This lowers the pressure in the diaphragm chamber q and the force generated by the pressure regulator spring e lifts the diaphragm.
As a guide, when W + P0a > P0A, adjust P1, so that it could be W + P1a = P0A. (1) The speed is controlled with meter-out control. When the meterin controller is used in conjunction with the meter-out controller, lurching is reduced. () (2) Installing a regulator with check valve at position (b) can decrease lurching during descent, and actuation delay during ascent.

At this time, read vacuum pressure P1, obtain the suction flow rate from the flow-rate characteristics graph for the ejector that is being used, and render this amount as the leakage of the workpiece.
