Good hydraulic oil cooling system for large hydraulic excavator hydraulic oil cooling system (or rather should the hydraulic oil temperature control systems) to improve, buy used Yuchai excavators, concrete way, although the manufacturers use different, but The basic idea is the same, both the hydraulic oil temperature in continuous operation in the balance in the ideal range, but also make the hydraulic system in the cold state can be quickly put to work when heating (oil reaches normal operating temperature range). In the case of a qualified hydraulic oil under the premise of used Yuchai excavator manufacturers, when there is overheating hydraulic oil, hydraulic oil cooling step to check the temperature control system and cylinder arm Check for cracks or leakage. Check the battery electrolyte, a low level to avoid in the following lines. Air filter to prevent dust laden air into a large number of important parts of the excavator should always check the cleaning. Always check fuel, lubricants, Yunnan Used Yuchai excavators, hydraulic oil, coolant, used Yuchai excavators price, whether you need to add, and select the best oil in accordance with the requirements of the specification, and kept clean.
