1. Purpose

The PWS-50 electro-hydraulic servo catenary embedded channel fatigue testing machine adopts advanced electro-hydraulic servo control technology with advanced technology and complete functions. It is mainly used for fatigue life testing of embedded channels in electrified railway catenary tunnels. The embedded channel fatigue testing machine is one of the series of dynamic and static universal testing machines developed by our company. The main components of the testing machine, constant pressure servo pump station, hydraulic chuck and other key components are designed and manufactured by our company. The key outsourcing parts such as servo valves and seals are all selected international and domestic famous brands of similar products, which greatly improves the stability of the system And reliability, the overall performance of the testing machine is equivalent to the international advanced product technology level .
