Hydraulic excavator parked when long-term maintenance analysis: First, clean the lower part of excavator parts, chassis parts inspection, repair if necessary. Second, grease all lubrication points and refueling point, if necessary, to all exposed metal surfaces coated with oil. Third, remove the battery, in a cool dry place. Otherwise, the battery will soon put all electronic badly damaged. Fourth, it is best to dry the excavator into the garage, covered with tarpaulin, waterproof and dustproof. Fifth, the various tools stored in the toolbox. Sixth, once a month, rust running, start the engine, operating excavator agencies operate, so that the oil is distributed to everywhere. Excavators, driven by the development of modern industrialization, excavator progress is very large, excavator manufacturers for the majority of users a summary of some aspects of the use of knowledge, hope you can help. (1) Symptom: modern digging machine work 1700 hours, the user repair small excavator, the engine water temperature is high. (2) process: Inspection tank water level is normal, normal cooling fan, fan belt tension is normal, there is no belt slippage smallest excavator price, oil oil, the oil level is normal. Test machine discovery: namely short high temperatures, discharge pressure in the water radiator, radiator cap open, run the engine radiator coolant found in the water will flow, and the water system is working properly. Water system is working properly, you can exclude the pump, thermostat malfunction, check the upper and lower water temperatures close to the radiator inlet and outlet pipe and remove the thermostat does not open fault. Check the water radiator small excavator price list, found the water radiator appearance of a severe dust debris buildup, it is determined that the water bulk water surface dirt buildup caused by bad ventilation scattered small excavators 60 price, causing high temperatures. (3) results: Clear water surface after loose dirt buildup, fitted retest machine troubleshooting. (4) Failure Analysis: high engine water temperature caused by many reasons, failure investigation should be itemized. Radiator surface is almost covered, since this surface is radiator and oil cooler in the middle, it is difficult to see visually check the time must be thoughtful, any possibility of causing the problem can not be missed. (5) Processing the experience: on-site troubleshooting, guided by simple to complex, from the periphery to the interior of the exclusion principle.
