METHOD AND DEVICE FOR FIXING fact of exceeding the allowable pressure of the hydraulic fluid and registration of its maximum value

摘要

FIELD: machine building.;SUBSTANCE: method to record the fact of hydraulic medium overpressure and recording of its maximum value is based on using dependence between compression force and elastic deformation of a spring. The recording of the overpressure fact is carried out by means of damage of the control membrane with a stem driven by a piston under action of hydraulic medium pressure force. The position of the stem after fixation of the fact certifies maximum pressure, which influenced all elements of the hydraulic system. There is a device that realises the above method for recording of the hydraulic medium overpressure.;EFFECT: development of a method and a device making it possible to record the fact of overpressure and its maximum value without participation of an operator.;2 cl, 2 dwg
