Estimating the term…
A bypass control apparatus is used with a pump pumping a fluid therethrough. A bypass flow line circulates fluid about the pump. A bypass valve is interposed in the bypass flow line and moves between an opened state to permit the fluid to circulate through the bypass flow line back to the pump and a closed state to prevent the fluid from circulating through the bypass flow line. A sensor determines an existing flow-through rate of the fluid flowing through the pump. The controller communicates with the sensor and the bypass valve and moves the bypass valve to the closed state when determined that the existing flow-through rate of the fluid through the pump is at least a predetermined flow-through rate and moves the bypass valve to the opened state when determined that the existing flow-through rate of the fluid through the pump is less than the predetermined flow-through rate.
A bypass control apparatus adapted for use with a pump pumping a fluid therethrough, comprising:
A bypass control apparatus adapted for use with a refrigeration plant in fluid communication with a primary flow line having a pump for circulating a refrigerant about the primary flow line and through the refrigeration plant, the bypass control apparatus comprising:
A method for maintaining a predetermined flow-through rate of a fluid flowing through a pump connected to and in fluid communication with a bypass flow line with a bypass valve interposed in the bypass flow line, comprising the steps of:
An apparatus for maintaining a predetermined flow-through rate of a fluid flowing through a pump connected to and in fluid communication with a bypass flow line with by pass valve interposed in the bypass flow line, comprising:
An apparatus for maintaining a predetermined flow-through rate of a fluid flowing through a pump, wherein the means for opening and closing the bypass valve is operative to move the bypass valve to and between a closed state and an opened state, the opened state being one of a wide opened condition and a partially opened condition defined as being between the wide opened condition and the closed state.
