Abstract

The invention relates to mechanical hydraulic drive and can be used in hydraulic systems of mobile machines. The purpose of the invention is to increase the reliability and accuracy of the system. The method of protecting the hydraulic system from loss of working fluid during its depressurization consists in registering the flow of the pump 7 by the rotational speed sensor 16, the signal of which is compared with the signal of the current flow meter sensor 4 installed on the inlet pipeline, in the comparison unit 21 controlling the system operation sets the value of the normalizing value of the reference signal in the comparison block. 1 hp f-ly, 5 ill.

Claims (2)

  1. Claim
    1. A method of protecting the hydraulic system from the loss of the working fluid during depressurization of its elements, which consists in registering the pump supply with a speed sensor, the signal of which is compared with the signal of the sensor of the flow meter of the current flow rate of the system in the comparison unit, which controls the operating mode of the system, to increase the reliability of the system, by supplying a pump, the normalizing value is set, the values of the reference signal in the comparison unit, and the current value of the flow rate of the hydraulic system is measured at the suction pump.
  2. 2. The method according to claim 1, with the fact that, in order to improve accuracy, measure the current value of the air supply to the hydraulic tank, generate an additional signal and feed it to the comparison unit.
