The Research On The Improvement Of Signal Equipment Maintenance Based On TPM In Tianjin Metro

TPM maintenance strategy(Total Productive Maintenance)is a more advanced equipment management model,which is widely used in the world currently.TPM has been positioned as a device-centric maintenance improvement system,based on 5S activities,through the independent maintenance activities of all employees to improve the work environment continuously,so as to improve the staff's sense of responsibility,sustained Improve the quality of equipment maintenance.Tianjin Metroas a large public service enterprises,Equipment technology content is relatively high,equipment maintenance environment is complex,in particular,to ensure the safe operation of subway signal equipment has become the primary task of equipment management.In recent years,with the increasing lines of Tianjin Metro,the scale of operation is increasing,the complexity of professional management and security requirements of operation are also improving.For the signal equipment and other key equipment,poor stability has become a prominent problem affecting the quality of passenger services.Therefore,the application of TPM maintenance strategy in Tianjin Metrorailway signal equipment management has important practical significance to reduce equipment failure rate,improve operation and management methods and improve the service level of the company.In this paper,we mainly use the theory and management ideasof TPM,combined with mode of equipment management and characteristics of signal equipment operation in Tianjin Metro,analyze signal equipment management problemsin-depth,developthe implementation planof signal equipment TPM maintenance improvement.During the implementation of the program,Tianjin Metro Corporation has established TPM organization and compiled the implementation plan of TPM activities,laying a solid foundation for the promotion of TPM activities.At the same time,we actively carry out 5S activities,independent maintenance activities,Equipment improvement activities and personnel education and training activities,the work environment has been greatly improved through 5S activities;the stability ofsignal equipment has been greatly improvedthrough the implementation of independent maintenance activities,equipment Improve activities in 2016.The effect of Staff training is obviousthrough the use of OJT and OPL means.Through the evaluation of the effect of the improvement activities and the comparison of the implementation of the activities before and after,it is proved that the implementation of the TPM activities haspromoted the improvement of the overall level of the maintenance and management of the signal equipment and brought tangible and intangible effects to the Tianjin Metro.
