The machine will definitely overheat during long-term operation, and hydraulic machines are no exception. This situation will certainly occur when a hydraulic machine works continuously for more than ten or twenty hours. At this time, the machine needs to be cooled. , Because the temperature is too high will not only affect the work efficiency, but also damage the machine itself, if it is not properly handled, the service life of the machine will be greatly reduced.
1. Hydraulic oil with proper viscosity should be used
2. If there is a hose in the system, it should be clamped and positioned reliably. Changing a hose too close to a place with high temperature will cause the hose to overheat and cause the oil passing through it to overheat. Therefore, avoid using hoses with insufficient length and make sure that the installed hose does not have sudden sharp bends. , This will also increase the friction of the oil flow, resulting in an increase in the temperature of the oil.
3. When the hydraulic cylinder and other hydraulic components are worn out, they should be replaced in time. Because the worn components will cause the increase of leakage, the pump will output at full flow for a long time, and the oil passing through the narrow leakage gap will cause a large pressure drop. The increase in the time of full flow output also increases The time for the friction of the fluid to be generated, therefore, the temperature of the oil will rise.
4. Keep the exterior and interior of the hydraulic system clean. The pollutants outside the system can isolate and hinder normal oil cooling. The pollutants inside the system will cause wear and tear and cause oil leakage. The occurrence of both situations will cause heat to be generated.
5. Frequently check the liquid level of the fuel tank. If the oil level is too low, the system will not have enough oil to take away the heat.
6. Regularly replace the filter element to avoid clogging of the filter
7. Excessive oil return back pressure is also one of the reasons why the back pressure is too high. The reason for the increase in back pressure should be checked and eliminated
8. Check the cooler regularly and descale the cooler regularly.
