AUTOMATED CONTROL SYSTEM TECHNICAL CONDITION OF HYDRAULIC

摘要

the technical condition of the hydraulic drive of the automated control system is designed for technical diagnostics of hydraulic drives for any purpose, including lifting equipment. Gidrotester system comprises a three-way valve crane and electronic control and data processing unit to which the interface means of radio bridge, or connected computer. Gidrotester comprises pressure sensors, piezo-pressure to the primary pressure pulse converter in shaft speed, temperature sensor and throttle washer constant cross section. The outputs of the sensors are connected to electronic control and data processing. A throttle washer is simultaneously loading device and the fluid flow sensor. The first and second outputs of the three-way crane spreader are respectively connected to the output of the pump and hydraulic drive diagnosable systems, and the third output is connected to gidrotesteru. In addition, the crane threeway valve through a reduction gear and a motor connected to the electronic control and data processing. According to a predetermined program switches the three-way valve and fixation of the crane spreader in three operating positions. The system has a speed and allows for remote technical diagnostics of hydraulic drive. 1 NC and 3 h. Nos. f-ly, 4 Fig.
