  Abstract:In order to ensure the good running status of draw frame and lap machine combined，reduce the maintenance time，and meet the requirements of high-speed and high-efficiency production，the fault performance is described in detail，and targeted analysis of its maintenance points is done.The fault performance includes the electrical faults of display screens，inverters，solenoid valves and photoelectric sensors，the failure performance of pneumatic components of cylinders and pneumatic control valves，the mechanical failure such as the chuck rising 1 mm，frequent trouble-free parking，lap chuck with empty tube，the action stopping when the chuck rises to the high position，the chuck opening and closing inconsistently，transmitting empty tube，sliver broken or gushing after the machine，and sliver broken or gushing after the machine in full coiling time. It is pointed out that the draw frame and lap machine combined has a high level of automation and integration，and has strong automatic monitoring capabilities.It uses sensors to monitor and control the accurate action of each pneumatic component.Daily maintenance should start with equipment basic management，and combine periodic maintenance with state maintenance.We should carefully overhaul and maintain to reduce maintenance leaks,and strengthen technical training to enable employees to fully grasp the structure principle of draw frame and lap machine combined，familiar with the causes of mechanical and electrical control component failures， and can quickly repair according to the failure type.
Key Words:draw frame and lap machine combined；solenoid valve；sensor；cylinder；pneumatic control valve；chuck；transmitting empty tube；cotton sliver；automatic barrel replacement
