Embodiment Construction
[0052] The present invention is described in further detail below in conjunction with accompanying drawing:
[0053] like figure 1 As shown, the system includes the following modules:
[0054]Mechanical installation carrier: the control valve 2 is fixed by the press-fitting fixture 1, and the press-fitting fixture 1 has the inlet port, the outlet port and the exhaust port corresponding to the inlet port, the outlet port and the exhaust port of the control valve 2 Interface; the air inlet interface is connected to the air source 3 to input stable air pressure for the control valve. In this implementation, the air pressure adjustable air source is preferred for the air source 3, and the air pressure value can be adjusted between 0.6 and 1.2 MPa to simulate the air supply pressure of the whole vehicle.
[0055] Air pressure acquisition device: through the pressure sensor 4, the output pressure of the gas outlet of the control valve is collected in real time, and the range of the...

The invention discloses a control valve detecting system and method of a hydraulic retarder. The detecting system comprises an air pressure collecting device, a valve control device, an upper computerterminal and a communication device. A control valve is fixedly arranged and an air inlet of the control valve is connected with an air source. A measuring end of the air pressure collecting device is connected with an air outlet of the control valve; and the air pressure collecting device is used for collecting the output pressure of the air outlet of the control valve in real time. The output end of the valve control device is connected with a control end of the control valve; the valve control device is used for applying current signals changing based on a set rule to the control valve; and the input end of the valve control device is connected with the output end of the air pressure collecting device. The upper computer terminal in interactive connection with the valve control deviceis used for displaying and recording a control valve data signal and controlling starting or stopping of the valve control device. The communication device in interactive connection with the upper computer terminal and the valve control device is used for realizing real-time data transmission between the upper computer terminal and the valve control device. Therefore, various values of the controlvalve can be displayed to realize detection of the control valve. The control valve detecting system and method can be applied to after-sales failure analysis of the control valve.
Description
technical field [0001] The invention belongs to the field of hydraulic retarders, and relates to a hydraulic retarder control valve detection system and method. Background technique [0002] With the release of relevant industry regulations and the improvement of users' recognition of retarder products, the output of hydraulic retarders has increased greatly in recent years. Issues of focus. [0003] The control valve is the key actuator on the retarder. It receives the current signal from the retarder controller, converts it into corresponding air pressure and outputs it to the oil pool shell, and injects oil into the working chamber to make the retarder work. The quality of the control valve directly affects the performance of the entire retarder system, and its consistency and sensitivity must be maintained at a high level to ensure the reliability of the output of the hydraulic retarder. [0004] For the detection of the control valve, the existing method is to install...
