Electronic Control Technology And Fault Diagnosis Of Ship Crane

The development experience of ship building industry shows that if we want to develop the ship building industry, we must develop suitable marine equipment industries of the ships. At present, most domestic production of ships equipment still needs to introduce foreign advanced technology. To build China into the world’s largest shi p building country, we must develop the supporting industri es of the shi p.Ship’s cargo winch is one of the essential deck machinery in ships, it is mainly used for loading and unloading cargo in port. It has greatly improve the efficiency of the cargo carrying, and creates high economic benefits.Ship crane is a kind of winch used in many ships, it is composed of the lifting mechanism, luffing mechanism, and rotating mechanism. At present, it mainly adopts simple relay contactor control mode. This control method is simple and intuitive, but it has many disadvantages, like various components, high fa lure rate, difficult maintenance management, low efficiency of loading and unloading cargo. This directly affects the economic benefits and social benefits. With the development of Micro control in recent years, micro control in crane shows more and more advantages. MCU and PLC control can achieve the control function of the hoisting system in cranes, and it also provides the protection system and display alarm function. The crane integrates machine, fluid, electric equipment, this is a complicated system. With bad work condition, it is very important for the daily maintenance and management. Through consulting a lot of data, this topic put forward the scientific management methods and indicate part which should pay special attention to. With the high failure rate of crane, this topic points hydraulic malfunction and electrical malfunction. According to the current common fault analysis, this topic analyze the causes of fault, and put forward the corresponding solution. The topic analyzes several ship cranes failure which often occurs, and use the method mentioned in the text to analyze fault solutions.The study of thi s topi c i s very i nnovati ve and practi cal to the development of shi ps. It has a certain guidance and reference significance in control technology research and fault diagnosis of the crane.
