Overview of the faults and diagnosis methods of the hydraulic system of modern coal mining machines

The high power, high efficiency, low failure rate, and intelligence of coal mining equipment are important directions for the development of coal mining machines both domestically and internationally. The implementation of efficient and low failure coal mine equipment is an important prerequisite for ensuring the smooth deployment of intelligent mines. At present, coal mining equipment generally consists of three parts: mechanical, electrical, and hydraulic. However, hydraulic pressure is a necessary system for coal mining equipment to complete high-power and intelligent operations. This article will combine the author's years of work experience to summarize the current local faults and diagnostic methods of hydraulic systems in coal mine equipment.
