• Application of Oil Monitoring in Coal Mining Machinery

With the increasing development of mechanical equipment towards heavy load, high speed, large size, automation, multifunctionality, and utilization rate,The maintenance cost and downtime loss of equipment have sharply increased,Therefore, the requirements for the reliability and economy of equipment operation are becoming increasingly stringent,This has led many enterprises to propose a focus on prevention and rely onEquipment status monitoringNew measures to improve the safety and reliability of equipment operation.

As a coal mining enterprise, the use conditions of mechanical equipment are harsh,Serious damage to mechanical equipment,Affects normal production and safety,It is necessary to establish a monitoring system to improve the equipment integrity rate,Reduce unnecessary investment. Especially sometimes inadequate monitoring,A small accident leads to a big accident,The losses are enormous. Coal mining enterprises should establish an oil monitoring system by doing the following:3 Item of work:

（1） Equipped with various high-quality and fully functional oil inspection instruments and equipment,Has the characteristics of multiple testing items, large quantity, and fast speed,Provide accurate and timely data for rapid fault diagnosis. Hardware facilities need to be equipped with wear and pollution particle monitoring instruments such as emission spectroscopy, infrared spectroscopy, ferrography, and particle counting,Viscosity, flash point, moisture, total acid number, total base number, pour point, foam, insoluble matter, mechanical impurities, etc. are also required10 Conventional oil testing methods. Software aspects:,Establish a laboratory and monitoring data LAN,Transmit monitoring data and oil detection data of major equipment such as coal mining machines, transport machines, main ventilation fans, air compressors, etc. to the mechanical and electrical department and the main leaders of the mine,In order to take corresponding measures Second,Establish a fully functional database management system and report generation system,Generate oil monitoring reports in various formats Third,Establish a computer intelligent diagnostic system based on expert knowledge,Improve the accuracy and scientificity of problem-solving.

（2） Should meet the requirements of regulatory standards,Ensure the detection capability with sufficient accuracy of test results,Considering the economic feasibility,Achieve monitoring effect with fewer testing items For those with national standards andISOandASTMWaiting for standard testing methods,Testing should be strictly carried out according to standard methods,To ensure the rationality and impartiality of monitoring and diagnostic conclusions.

（3） We should establish a high-quality and high-level expert team with rich experience accumulationOil monitoring technologyranks. By collaborating with higher education institutions and research institutes,Cultivate a solid theoretical foundation,Monitoring personnel with practical experience in oil monitoring and diagnosis,And continuously leverage the technical value of professionals in solving practical problems.

Different forms of equipment failures,Different methods can be used for equipment maintenance. The main maintenance methods include regular maintenance, post maintenance, and predictive maintenance. Regular maintenance refers to preventive maintenance,Require the equipment to operate for the specified time,Regardless of the condition of the equipment,Perform maintenance and repair according to the prescribed content,In order to eliminate equipment hazards. This method is widely used in the repair of coal mine comprehensive mining equipment,It requires regular maintenance and replacement,The cost is relatively high. Post repair refers to the maintenance carried out after the occurrence of a malfunction,When a series of faults are caused by the failure to timely detect and handle local faults,Then post repair must be carried out,Its cost is high and it affects normal production. Predictive maintenance is based on monitoring the condition of operating equipment,When predicting the possibility of a malfunction in a certain area,Eliminate potential faults through timely targeted maintenance,Therefore, predictive maintenance is the ideal method of repair.

fromOil monitoringDepart for mechanical equipment fault diagnosis,Can accurately predict the cause and location of faults,More comprehensive monitoring of equipment operation,And be able to use early forecasting to timely detect and eliminate potential equipment failures and hazards,Reduce losses. After more than a decade of development,Oil monitoring technology has become an important technical method for frictional monitoring and fault diagnosis.
