NOTICE:
During the work of the tunnel mucking loader machine, due to the high work intensity, the temperature of the parts will rise frequently and the parts will be damaged in serious cases, eventually causing the rock loader mucking machine to stop working. If reducing the temperature of the loader during operation becomes a problem, the temperature of each component of the actual loader has its own normal range. For example, the temperature of the general cooling water is 80~90°C, and the temperature of the hydraulic oil of the hydraulic transmission system is 30~60°C. Below or above this range will accelerate the wear of the mucking loader machine parts, causing the deterioration of the lubricating oil and causing the material properties of the loader components to change. and many more. How to reduce the temperature of the loader at work? Let us take this issue together with the technical staff of China Coal to learn more about it!
In actual operation tunnel mucking loader machine or in experiments, the main drive gears and bearings of various parts of the loader are operated in lubricating oil at -5 ° C than in lubricating oil at 3 ° C, and the wear is increased by 10 to 12 times. However, when the temperature is too high, it will accelerate the deterioration of the lubricating oil. If the oil temperature is 55~60°C, the oxidation rate of the oil will be doubled for every 5°C increase in oil temperature.
To this end, during the use of the tunnel mucking loader machine, it is necessary to prevent overload operation at low temperatures, ensure normal operation in the low-speed pre-warming phase, and then drive or work after the machine reaches the specified temperature. Do not ignore the problem because there is no problem at that time. It is important to prevent the machine from running at high temperatures. If the loader exceeds these data during operation, it must be stopped to check the problem, or the loader can be cooled down, and the damaged loader parts can be found even if the replacement is repaired.
If you are not familiar with the tunnel mucking loader machine, you can't find the cause for a while, and you must not let the loader work with the disease without treatment. In the usual work, pay attention to check the working condition of the cooling system. For water-cooled machinery, it must be checked before daily work to add cooling water. For air-cooled machinery, the dust on the air-cooled system should be cleaned regularly to ensure the smooth flow of the tunnel mucking loader machine.
