Recently, Yongjia Suntory Electromechanical Hydraulics Co., Ltd. and Jiangsu company signed a 60000N.m intelligent hydraulic valve torque testing machine (with life testing and performance testing) has been commissioned on-site commissioning acceptance. It is understood: Yongjia Suntory Electromechanical Hydraulics Co., Ltd. in the original hydraulic valve pressure testing machine based on an increase of torque testing system, life testing system, PLC control system and data acquisition system. It is understood that: the general valve factory pressure test and parts processing dimensional accuracy, position accuracy, roughness inspection can not be completely measured in addition to the inherent quality of the valve products. There are inaccurate factors to choose valve actuator through theoretical calculation. Yongjia Supor Electrical and Mechanical Co., Ltd. developed a hydraulic hydraulic torque testing machine hydraulic valve, valve life test and torque through the test, the valve on a specific pressure environment for switching cycle test, the number of switches and torque curve can be understood Valve life characteristics, failure and failure of the form. Combined with the causes of failure, analysis and resolution provide a strong basis for reliability design and structural rational design and improvement of product quality and selection of actuators. In fact, the torque test and life test is to reflect the comprehensive performance of the valve test.
