This article introduces the prevention and maintenance of coal mining scraper conveyor faults.
In the transportation equipment used in the underground production and mining areas of coal mines, coal mining scraper conveyor is basically the main transportation equipment. Due to various factors such as long operation time, uneven load, improper use, inadequate maintenance, and harsh environmental conditions, motor damage accidents often occur, directly affecting the safety production of coal mines. A detailed analysis from the system is mainly affected by the following four aspects: mechanical faults, electrical faults, overheating faults, and motor dampness. So how to ensure the safe and reliable operation of the motor and pay attention to prevention is very important. Below, the editor will explain from the following aspects, paying attention to these points. It is crucial to do a good job of pre inspection and prevention.
① Improve the quality of maintenance. During the class, it is necessary to conduct patrol inspections, promptly handle any problems found, and comprehensively and comprehensively identify the causes from multiple perspectives.
② Regularly conduct integrity checks to prevent water, oil, and dust from entering the interior of the motor.
③ Regularly measure the ground insulation and phase to phase insulation of the motor, keep records, and promptly identify the cause of insulation reduction.
④ Regularly measure the power supply voltage of the system, and record the results. If the voltage is unstable or too high, it should be adjusted in a timely manner.
⑤ For motors that have been running for a long time, regular comprehensive and systematic inspections should be conducted, and separate trial runs should be conducted to facilitate the identification of problems.
⑥ Carefully fill in the operation and maintenance records of the motor, especially the fault records, and provide detailed information on the time, location, and characteristics of each fault.
