At what temperature is the small roller suitable for operation

There are also many points to be paid attention to in the daily use of small rollers, which will affect the use of small rollers to a certain extent. For example, the temperature of each component of a small roller has its own normal range during its operation. For example, the temperature of general cooling water is 80-90 ℃, and the temperature of hydraulic oil of hydraulic transmission system is 30-60 ℃. Lower or higher than this range will accelerate the wear of parts, cause the deterioration of lubricating oil, cause the change of material properties, etc. The test shows that the wear of the main transmission gears and bearings of various construction machinery in - 5 ℃ lubricating oil is 10-12 times greater than that in 3 ℃ lubricating oil. However, when the temperature is too high, the deterioration of the lubricating oil will be accelerated. For example, when the oil temperature exceeds 55-60 ℃, the oxidation rate of the oil will double every 5 ℃ increase in the oil temperature.

Of course, during the use of small rollers, it is also necessary to prevent overload operation at low temperature, ensure the normal operation of the low-speed pre-heating stage, and make the machinery reach the specified temperature before driving or working. Do not ignore its important role because of trouble; Second, the machine should be prevented from running under high temperature. During the operation of the machine, the values on various temperature gauges should be checked frequently. If any problem is found, the machine should be shut down immediately for inspection. If any problem is found, it should be removed in time.

If the cause cannot be found at the moment, the machine cannot work without treatment, which not only has low efficiency, but also affects the internal hardware of the small roller. In normal work, the working condition of the roller cooling system should be carefully checked. For water-cooled machinery, check and add cooling water before daily work; For air-cooled machinery, dust on the air-cooled system should also be cleaned regularly to ensure that the cooling air duct is unblocked.
