As spring approaches, everything recovers Excavator also ushered in the busy spring season After being sealed for a long time in cold winter, various oils, lubrication protection and some materials of the excavator may change. If the machine is started and put into operation without detailed inspection, poor operation may occur In order to reduce equipment failures and ensure the best performance of the machine after construction in spring, the excavator shall be inspected and maintained in detail before commencement The inspection is mainly divided into pre startup inspection and operation inspection Master Wang of Komatsu excavator repair meiruite maintenance factory gave a detailed introduction to Komatsu 360-7 excavator.
Inspection before starting Komatsu 360-7 excavator
1. Check the fuel tank, clean it if necessary, check the fuel level, and drain the fuel tank (drain the oil-water separator);
2. Check the fuel system rubber hose for aging, cracking and oil leakage, and whether each joint is firmly connected. Replace it if necessary;
3. Check the oil level and quality, and add or replace IHI special oil if necessary;
4. Check whether the engine foot pad is intact;
5. Check the tension and aging of fan belt and air conditioning belt, and adjust the tension of fan belt and air conditioning belt or replace it if necessary;
6. Check the hydraulic oil level, rubber hose and oil quality, and add or replace IHI special hydraulic oil and rubber hose if necessary;
7. Check the oil level and quality of the traveling speed reducer, and add or replace IHI special gear oil if necessary;
8. Check the cooling liquid level and each water pipe tank for cracks and water seepage. If necessary, fill IHI special coolant and replace the water pipe;
9. Check the working condition of the detection instrument;
10. Check the tension of the track;
11. Check whether the bearing grease of the slewing mechanism is sufficient, and add it if necessary;
12. Check whether the grease of the rotary big gear ring is sufficient, and add it if necessary;
13. Add grease to each pin shaft and lubrication point, and extrude the old oil from the oil passage if necessary;
14. Check the tightness of each fastener bolt
Inspection of Komatsu 360-7 excavator in operation
① When the ambient temperature is lower than 3 ℃, turn on the preheating switch before starting to preheat the intake air;
② For models with turbocharger before starting, remove the oil inlet pipe of turbocharger and add an appropriate amount of engine oil to ensure the lubrication of turbine shaft
③ Start the machine, after the engine runs at idle speed for 5-10 minutes, operate each oil cylinder without load to make the hydraulic oil temperature reach 40 ℃, circulate all hydraulic functions for several times, and then carry out construction;
④ If Komatsu excavator repair machine is not used for a long time, the thin oil layer on the sliding surface may be damaged 2. It is necessary to lubricate the excavation surface by hydraulic circulation for 3 times;
There is freezing weather, when the soil is on the rack, before moving, shovel the upper frame to 90 degrees, hold up the track, turn around several times before and after, throw off the sprocket, the supporting wheel, and the soil impurities around the guide wheel.
