Intermediate maintenance worker for electrical and mechanical equipment, should equipment maintenance point of failure to master a certain knowledge of technical skills to track closely “monitor”. Welding deformation and welding stress “eliminate” hidden from the control of complex components, was often found when the rake installed the fastening bolts of the connection plate at easy Duanzhe to expand through-hole, the upper and lower contact surface welding method, the device “impregnable” durable. From the action value of maintenance, the protection of a variety of electrical equipment “care” safety for the mine explosion-proof smart feed switch to achieve “quick break” function, according to the equipment used to power the size of the “accurate” to “rated resistor current, zero sequence current, undervoltage set value, the undervoltage delay, leakage detection, leakage detection delay “all the setting value. According to the noise determine the machinery and equipment defects “force” to crack, hear abnormal helical gear noise, increase the wheel thickness rather than to increase the tooth thickness of the ways to improve its natural frequency, eliminate the thin-wall vibration. With learning problems, constant “load” to find the job capacity gap, set the post ability of the makeup of the training task, out of the state of the “Love expenditure”.
Advanced electrical and mechanical equipment maintenance man with outstanding job skills to transport the “frontier science and technology, information technology, thereby enhancing the status of science and technology innovation capability. Weldability considerations from material weldability estimation methods and different natural conditions, different for the melting point of the variable air-cooled flat internal spiral brass road production of solder with silver solder welding, flame tone is extremely appropriate. solve the refractory alloy copper and iron, prone to crack the problem, the cumulative fix the air cooler, material savings of maintenance costs over 100 million. Difficult exclude equipment failure, multiple, repetitive equipment failures and equipment congenital put forward practical and effective reform measures, 50/12.5 ton gantry crane for the “old sound of the old tune”, the main hook 4 gear connected drive reducer, has left the running of the “worry”. Take independent Turning spring pins, innovation as a flexible connection transmission mode, the “big mouth” no movement. From the selection of programmable logic controller programming, and new equipment to meet production needs. Smart semi-automatic and plasma cutting machine, batch cutting the steel plate of 12mm-30mm all kinds of shapes, “uncertain” to import research by LG programmable controller the preparation of the graphics library file, repeatedly set up an experiment, “finalized” pulse the equivalent value of 0.004000-0.006000 the middle of the cutting start speed 800-1000, acceleration to 600. “Perfect” use of the device, unmanned conduct run automatically, without using oxygen acetylene, and save the supplies of the production of the workpiece. With the innovation school “continually” turn around “mine production needs, hastened the development of innovative training of job ability” Express “, to” smart spending “state.
