Case Details
Requirement analysis: As a coal mining enterprise, the use of machinery and equipment in harsh conditions, serious damage to machinery and equipment, affecting normal production and safety. It is necessary to establish a perfect monitoring system to improve the equipment integrity rate, reduce unnecessary investment. As a coal enterprise, coal mining machine and other harsh operating environment, moisture, dust and other external factors, the pressure on equipment maintenance is self-evident, the establishment of scientific and effective management tools is the industry’s top priority.
➢ Harsh working conditions:
Coal mining equipment usually operates under harsh working conditions, including high temperature, high pressure, dust, etc. These conditions may have an impact on the performance of the lubricant fluid.
➢ Particle contamination:
Coal mining operations generate a large amount of dust, which may enter the equipment’s lubrication system, leading to excessive contamination particles in the lubricant fluid and affecting lubrication effectiveness.
➢ Moisture intrusion:
Moisture may be present in the coal mining environment, especially in underground mining. The presence of moisture may lead to dilution, oxidation and contamination of the lubricant fluid.
➢ High loads:
Coal mining equipment is often operated under high loads, which can lead to increased friction and wear, requiring superior lubrication and anti-wear performance.
➢ Safety Risks:
In coal mining operations, leaks or external factors can cause lubricants to leak, increasing the risk of fire and explosion.
➢ Surface Operations:
Some coal mining equipment operates in surface operating environments and is exposed to temperature, humidity and weather changes in the natural environment.
Solution: Fault diagnosis of mechanical equipment from the online monitoring of oil, can more accurately predict the causes and parts of the fault and more comprehensively monitor the operation of the equipment. It can also utilize the early prediction of timely detection and elimination of hidden equipment failures and reduce losses.
Yateks YOL online oil monitoring system can monitor the quality changes of the equipment fluid in real time, discover abnormal conditions such as contamination, oxidation, and moisture in the fluid in a timely manner. It provides intelligent and efficient equipment monitoring as well as corresponding early warning and maintenance programs to avoid equipment failure and major accidents, and to inject new impetus into the digital transformation and sustainable development.
Actual case: This group is a large-scale modernized energy enterprise with coal production and operation as its main business, railroad transportation and coal-to-oil as its industrial extension, and real estate development and other non-coal industries as its complementary business. The company has been ranked among China’s top 500 enterprises for 12 consecutive years, and the pressure of equipment management work is very great. After careful consideration, the group’s leaders chose to cooperate with Yateks in oil monitoring, and achieved very good effect.
Oil type: No. 320 hydraulic oil
Monitoring indexes: Kinematic viscosity, density, temperature and wear debris particles
So far, the coal mining machines of the group have been running well under the monitoring of our oil monitoring equipment, and have been well received by the users.
