Abstract

PURPOSE: To supply a necessary quantity certainly and to enable a remote control of a flow rate control pump which controls the supply of a fixed quantity of fluid automatically, by arranging a computer which controls the reciprocation of a plunger and the opening and closing motion of an automatic valve.
CONSTITUTION: At first, by commands of a microcomputer 10, a solenoid valve 7 is opened, a plunger 4 is operated and a diaphragm 3 is worked, and fluid is sucked. Thereafter, the solenoid valve 7 is closed and a solenoid valve 8 is opened, and the fluid is ejected by the work of the diaphragm 3, and then, the solenoid valve 8 is closed. By repeating this process, the pump functions, and by controling the cycle, a quantity of flow is controled. Namely, by setting a program, which computes the quantity of flow by the microcomputer 10, determines a cycle and instructs commands, on the computer, a certain quantity of flow can be supplied.
