Sany adopts innovative anti-corrosion laser cladding technology.The salt fog test for the electroplating performance is up to 1,800h, longer by 400~500h than that specified by national standard.
The laser cladded stainless steel eliminates the formation of porosity cracking to thus isolate the contact between water and base material and achieve permanent anti-corrosion performance for the piston rod. (After 1,000h salt fog test, the one with Sany anti-corrosion technology almost has no change and the double chrome plating is already corroded)
The valve internal flow field and dynamic characteristics of the supports are analyzed by CFD computational fluid mechanics to realize the optimized matching between valve internal channel structure and flow speed and differential pressure.
The high cost-performance electrohydraulic control system developed independently by Sany Heavy Industry Co., Ltd. innovated the wireless remote control device and video monitoring system to drive the intelligent development of supports and lay a foundation for the realization of automated underground fully mechanized mining working face with less manpower in the industry.
