Abstract: The work of the quality control of ZYJ7 electro-hydraulic switch machines is introduced. The status of the quality control of ZYJ7 electro-hydraulic switch machines is reported. According to the practice, the quality control of ZYJ7 electro-hydraulic switch machines is improved, and a set of relatively complete quality control methods of ZYJ7 electro-hydraulic switch machines is summarized. The main manufacturing control work is divided into three parts: the quality control of the source of the parts, the quality control of the key process of the whole machine assembly and the control of the whole machine performance inspection. The recent work results of the control work are summarized. Finally, the prospect of potential solutions to the deficiencies in the current quality control work of ZYJ7 electro-hydraulic switch machines is proposed.
