Study on working characteristics of high frequency electro-hydraulic cleaner

The traditional high-frequency cleaning scheme can not effectively deal with large components. In order to solve this problem, a high-frequency electro-hydraulic cleaner is proposed. The key part is the 2D four-way valve. This cleaner working frequency can be controlled by the spool speed and amplitude can be controlled by the spool axial displacement. The cleaner uses the 2D four-way valve to drive the piston rod in the hydraulic cylinder and to achieve piston rod reciprocating motion. Then the piston rod to drive the box vibrate quickly and to remove the dirt on the surface of the cleaned object, to achieve the purpose of cleaning and achieve high-power cleaning. The visualization of real-time data collection, display and preservation are realized by the data acquisition system. In this paper, the prototype of the cleaner is modeled and both a theoretical study and experimental investigation are carried out. The results show that the high-frequency electro-hydraulic cleaner can realize high-power cleaning with the maximum working frequency of 2669Hz. The measured waveforms show varying degrees of distortion under the effect of hydraulic resonance below the resonant frequency (1903Hz). However, the measured waveforms has been little effected when the vibration frequency above the resonant frequency. This scheme which uses 2D four-way valve to achieve high-frequency electro-hydraulic vibration can be applied not only in the cleaner but also in other fields.
