Abstract

The invention discloses an engineering machine speed control valve full-automatic performance detecting device. The engineering machine speed control valve full-automatic performance detecting device comprises a data acquisition display module, a hydraulic power source module, a speed regulation rod motion control module, an oil temperature rising and temperature control module and an installing clamp and installing oil path block module. By the adoption of the engineering machine speed control valve full-automatic performance detecting device, gears of a detected valve can be automatically controlled and changed, the rotating speed of a hydraulic station motor can be automatically controlled and changed, flows of oil passing through the detected valve of all gears can be changed, and then automatic detection of parameters of oil pressure and other performance of the valve under different gears can be achieved.

Description

Technical field [0001] The invention relates to the detection technology of hydraulic system components, in particular to the detection of oil pressure performance parameters of speed control valves commonly used on construction machinery vehicles. Background technique [0002] There are many speed control valves in construction machinery, which change the direction and speed of construction machinery. The performance of the valve, especially the hydraulic performance of each gear, has a very important influence on the speed control of construction machinery. Therefore, it is necessary to test the oil pressure performance of each gear of the valve. In the past, the oil pressure performance of the valve was mainly manually operated. The inspector manually changed each gear and manually moved the speed control lever of the detected valve to detect the displacement. Hydraulic performance. This backward detection method has low efficiency, high detection intensity and high detection...
