초록 ▼

The present invention discloses a system for pumping a fluid into a common pressure outlet. The system contains a plurality of reciprocating pumps. A separate sensor coupled to one cylinder of each pump provides an electrical signal each time the piston in that cylinder is at a predetermined position. A speed control circuit is provided to independently adjust the speed of each pump. Manual speed control for each pump is provided through a separate throttle for each pump. A pump control circuit coupled to each of the throttles, sensors and speed control circuit controls the operation of the system. An operator determines which of the pumps to operate by closing appropriate bypass switches provided at the pump control circuit, turns on the first (master) pump and adjusts its associated throttle to operate the pump at a desired speed. The operator then turns on each of the remaining (slave) pumps. The pump control circuit utilizing the information from each of the sensors provides control signals to the speed control circuit, which adjusts the speed of each of the slave pumps to synchronize the speeds of pumps and to maintain a desired phase shift between the sensor signals. The system also displays the speed of each of the operating pumps and the total fluid volume being discharged by all of the operating pumps.
