The characteristics and treatment of the equipment failure of the drilling rig

　　The characteristics of equipment failure include abnormal function, abnormal sound, abnormal temperature, abnormal appearance, abnormal consumption and abnormal smell. It is found that the above-mentioned fault characteristics of the equipment generally adopt the following treatment methods: the general method of fault inspection, first clarify the fault phenomenon, determine the location of the fault, and check the fault.

　　To find out the failure phenomenon requires the following work: ① to find out which failures have occurred before the failure; ② to find out which repairs and maintenance work have been done before; ③ to find out whether similar failures have occurred before.

　　It should be noted that when the diesel engine fails, if the diesel engine is still running and cannot cause harm, it should continue to run for a period of time to further observe the failure phenomenon and analyze it. Judging the location of the fault should be based on the different conditions of the diesel engine failure phenomenon, using practical experience, combining the structure and working principle of the diesel engine, as well as the operation and maintenance conditions, to conduct a comprehensive analysis, and the observation method and the auscultation method (abnormal sound judgment method) can be used , Smell method, touch method, partition method (partial stop method), verification method in order to initially determine the location of the fault.
