Hydraulic system rapid detection and fault acceleration composite system

Abstract

The invention provides a rapid detection and fault acceleration compound system of a hydraulic system and belongs to the technical field of hydraulic system auxiliary devices. The signal output end of an industrial personal computer is connected with a PLC and the signal input end of an analog signal output card. A signal output port of the PLC is connected with of reversing valves, a motor pump and a transfer case of a hydraulic loop, and sensors of the hydraulic loop are connected with the signal input end of a data acquisition card. The industrial personal computer, the data acquisition card, the PLC, the analog signal output card, and the hydraulic loop are fixedly connected with a transfer truck frame. The rapid detection and fault acceleration compound system is comprehensive in detection contents, simple in detection process and capable of further achieving assessment on a number of control port dynamic response characteristics except a pressure-flow curve, a control pressure-flow curve, opening pressure, closing pressure and other conventional data and capable of achieving leakage detection of most of regions of the system. Due to the fact that a fault acceleration system is added, the device performance assessment can be accelerated, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic system auxiliary equipment, and in particular relates to a hydraulic system rapid detection device and a fault acceleration device. Background technique [0002] For a long time, hydraulic systems have been widely used in the key executive components of various heavy machinery and equipment because of their characteristics of being able to achieve heavy loads, covering military and construction machinery fields. However, hydraulic equipment also has the disadvantages of easy damage to functional parts and heavy equipment that is difficult to carry. At the same time, the structure and connection of the hydraulic system are relatively complicated. The system mainly includes power source, control valve group, executive hydraulic pump, auxiliary components and hydraulic oil. For the five major parts, the fault detection requires better hydraulic detection technology, which takes a long time. In add...
