Abstract
The present invention is to provide a kind of multifunction passive and continuous fluid feeding system for external systems, the fluid-feed system including a storing and transmitting component, a measuring and regulating component, and a control unit characterized by: pressurizing from above fluid level surface of the feed fluid tank by high-pressure gas supply source to fulfill the passive fluid feeding function, performing the feed fluid measuring and regulating through the flow meter and flow control valve installed on the transmission pipe lines connecting to the external systems, fulfilling function of continuous fluid feeding by switching between two fluid-feed tanks, and combining the feed fluid requirements of the external systems through the control unit to achieve the multifunction fluid-feed art of automatic operation, continuous fluid feeding, and flow rate controlling. The present invention does not utilize high-head and high-pressure pumps as the driving components, thus it is not only cost-saving but makes easier in coping with various fluid-feed requirements by the external systems, hence, possessing potentials of extending applicability into various industrial fi…
