METHOD FOR FEEDING LIQUID AND APPARATUS FOR IMPLEMENTING SAME (VARIANTS)

摘要

The invention relates to the field of thermal engineering, specifically to a method for feeding liquid from a low pressure cavity into a high pressure cavity and an apparatus for implementing same. The method comprises a particular sequence for feeding liquid from a low pressure cavity to one or a plurality of intermediary cavities, which act as a heat pump, and also for feeding steam from a high pressure cavity to a filled intermediary cavity. The liquid from an intermediary cavity is fed into the high pressure cavity with the help of the steam. The apparatus comprises a low pressure cavity, a high pressure cavity and a heat pump, connected to one another. In a first variant the heat pump is in the form of two interconnected intermediary cavities, each of which is equipped with a float and electric contacts for detecting liquid levels. In a second variant the heat pump is in the form of a single intermediary cavity containing a float. Magnets are affixed to the inner surfaces of the cavity (to the top part and to the bottom part thereof) and also to the outer parts of the float. The claimed method and variants of the apparatus increase the efficiency of feeding a liquid.
