SIDE-BY-SIDE INSTALLATION OPERATION METHOD AND SIDE-BY-SIDE INSTALLATION OPERATION DEVICE OF ELECTROMAGNETIC PUMP

摘要

PROBLEM TO BE SOLVED: To provide a side-by-side installation operation method and a side-by-side installation operation device by which an influence of current generated by counter-electromotive force can be eliminated and discharge pressure with little pulsation can be obtained when carrying out side-by-side installation operation of electromagnetic pumps. SOLUTION: An electromagnetic pump which performs sucking operation by moving an electromagnetic plunger by electromagnetic force in such a direction that a pump house is enlarged when exciting an electromagnetic coil and which performs discharging operation by moving the electromagnetic plunger by repulsion energy stored in a spring in such a direction that the volume of the pump house is reduced when demagnetizing the electromagnetic coil, and an electromagnetic pump which performs discharging operation by moving an electromagnetic plunger by electromagnetic force in such a direction that a pump house is reduced when exciting an electromagnetic coil and which performs a sucking operation by moving the electromagnetic plunger by repulsion energy stored in a spring in such a direction that the volume of the pump house is increased when demagnetizing the electromagnetic coil, are installed side by side. A pulse current of the same phase is applied to both of the electromagnetic pumps. One of the electromagnetic pumps is started to perform the sucking operation while the other is started to perform the discharging operation, whereby the electromagnetic pumps are made to perform the discharging operation alternately.
