DEVICE TO CONTROL ELECTRIC PUMPS OF ARTESIAN WELLS

FIELD: artesian wells. ^ SUBSTANCE: invention relates to general-purpose regulating and control systems and it can be used to control electric pumps of artesian wells. Proposed control device contains switching element connected by inputs to supply voltage terminals and by outputs, to electric pump terminals, water level transmitter in water tower and electric pump check and control unit connected by first input with output of water level transmitter and by first output, with control input of switching element, voltage comparator, like inputs of first and second groups of inputs of voltage comparator being connected, respectively, with supply voltage terminal and with electric pump terminal connected with like phase, and voltage measurement unit whose inputs are connected with supply voltage terminals. Outputs of voltage comparator and voltage measurement unit are connected, respectively, with second and third control inputs of check and control unit of electric pump. ^ EFFECT: improved reliability of water supply. ^ 2 cl, 3 dwg
