  • Control Of Positive-Displacement Pumps (AREA)

Abstract

PURPOSE: To average the operation time of each equipment by composing a sequence control circuit for control over the number of equipments of an auxiliary relay and time relay so that the start sequence will be equal to the stop sequence.
CONSTITUTION: Pumps, when actuated in the order of No.1, 2 and 3, are stopped in the order of No.1, 2 and 3 under sequence control. In the figure, the pumps are sequentially actuated one after another without reference to the stop sequence at the point in time indicated by mark (○) and stopped one after another without reference to the start command of pumps (mark ○) at the point in time indicated by mark (black-circle). At part (x) in the figure, a request to operate one equipment intermittently is sent and at part (y), the number of equipments increases, one by one, from one to three, decreases and increases temporarily by one respectively, and then decreases, one by one, from three down to one in continuous operation, but they are started and stopped in the order of No.1, 2, 3, 1, 2... through the above-mentioned operation.
