Embodiment Construction
[0022] The framework of debugging system: including signal generator, digital multimeter, displacement sensor. Use a signal generator to input a 1000 Hz 5V square wave excitation signal to the primary of the displacement sensor of the product, monitor the secondary output AC voltage signal of the sensor with a digital multimeter, and adjust the core of the displacement sensor so that the zero output of the sensor reaches the target range.
[0023] After the assembly is completed, use a cable to connect the signal generator to the input end of the hydraulic spool sensor line package, and use the signal generator to input the corresponding electrical signal to the hydraulic spool sensor line package; The package output terminal is connected with a digital multimeter to detect the specific position of the sensor core for debugging.
[0024] The specific implementation process steps are described as follows:
[0025] Step 1: Remove the sensor wire cover;
[0026] Step 2: Adjust ...

The invention provides a debugging system and method for a hydraulic spool valve sensor zero position, and belongs to a multi-way valve displacement sensor debugging technology. The debugging method is achieved by adopting the debugging system. The debugging system comprises a signal generator, a digital multimeter and a displacement sensor. An excitation signal which is 1000 hertz and 5V square waves is input into the primary winding of the displacement sensor of the debugging system through the signal generator, an output alternating voltage signal of the secondary winding of the sensor is monitored by the digital multimeter, an iron core of the displacement sensor of the debugging system is adjusted, and therefore sensor zero position output reaches an indication range. According to thedebugging method for the hydraulic spool valve sensor zero position, the labor intensity can be effectively relieved, so that debugging work is not limited by a narrow space, and the debugging methodis safe and saves the labor; and the debugging method is high in operability and can obviously improve the working efficiency, and meanwhile the quality is ensured.
Description
technical field [0001] The invention belongs to the debugging technology of a multi-way valve displacement sensor, and in particular relates to a debugging system and a debugging method for the zero position of a hydraulic slide valve sensor. Background technique [0002] The excavator multi-way valve sensor is installed on the spool to detect the displacement of the spool. The movement of the spool directly controls the entire operation of the excavator. The sensor is used to feedback the position of the spool to realize the closed-loop control of the multi-way valve. , is a key part, and the debugging accuracy directly affects the movement accuracy of the excavator. [0003] When the debugging process of the excavator multi-way valve sensor is carried out on the test bench, due to the small space and often accompanied by additional media such as hydraulic oil, this makes the debugging process difficult to operate and easy to cause oil circuit pollution, which seriously aff...
