Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific examples.

[0016] When construction machinery equipment is working, a hydraulic actuator usually needs to complete two directions of an action. The following embodiments use a hydraulic actuator to complete two directions of action as an example for illustration.

[0017] like figure 1 As shown, a hydraulic solenoid valve jamming fault monitoring device includes a hydraulic solenoid valve 1, a hydraulic main control valve 2, a pressure monitoring device 4 in two action directions, a controller 6 and a power source 5, and the hydraulic solenoid valve 1 is the target monitoring object, and the two pressure monitoring devices 4 are respectively used to monitor the pressure state in the oil circuit in the two action directions of the hydraulic actuator controlled by the hydraulic solenoid valve 1. The hydraulic solenoid valve 1, the two pressure monitoring devices 4, the power The source 5 ...

Abstract

The invention discloses a valve jamming fault monitoring device for a hydraulic solenoid valve. The valve jamming fault monitoring device for the hydraulic solenoid valve comprises the hydraulic solenoid valve, a pressure monitoring device, a controller and a power source. The hydraulic solenoid valve is a target monitored article. The pressure monitoring device is used for monitoring the pressurestate of a hydraulic oil way in the hydraulic action circuit controlled by the hydraulic solenoid valve. The hydraulic solenoid valve, the pressure monitoring device and the power source are all connected with the controller. When the controller finds that the valve jamming fault happens through monitoring, the controller outputs the stop instruction to cut off the power source.

Description

technical field [0001] The invention relates to a valve stuck fault monitoring device for a hydraulic solenoid valve, which belongs to the technical field of engineering machinery. Background technique [0002] During the construction process of construction machinery and equipment, most of the execution actions are completed by hydraulic actuators. As the control element of the hydraulic system, the hydraulic solenoid valve is responsible for controlling the working state of the hydraulic actuator. It will enter a state of out-of-control, and there is a great potential safety hazard. Contents of the invention [0003] Objective: In order to overcome the deficiencies in the prior art, the present invention provides a hydraulic solenoid valve stuck fault monitoring device. [0004] Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: [0005] A valve stuck fault monitoring device for a hy...
