FIELD: mechanical engineering.
SUBSTANCE: device comprises inlet and outlet pipes (2) and (3) of the pump (1), sensors (4), (6) the pressure set at the inlet and outlet (2), (3), a comparator (10), the indicator (11), the block (12) control the counter (13) the time unit (14) ban, a computing device (15) and block (16) indication. The outlet connection (3) of the pump (1) are installed adjustable hydraulic restriction (8) and a sensor (7) temperature, the output of which is connected to the block (14) of prohibition.
EFFECT: reducing the cost of manufacturing by simplifying the design of the device to determine the technical condition of the pump.
