Routine maintenance excavator excavator to prevent failure, in daily use requires careful attention to the maintenance of the excavator. Routine maintenance includes inspection, cleaning or replacement of the air filter; clean the inside of the cooling system; check and tighten the track shoe bolts; check and adjust the tension of the anti-track; check the intake heater; replace bucket teeth; adjust the gap bucket; check the front window Cleaning fluid level; check, adjust the air-conditioning; clean cab floor; replace broken filter element (optional). When cleaning the inside of the cooling system, to be fully cooled engine, slowly loosen the filling opening, Tai'an excavators school phone, release the internal pressure of the tank, and then to turn on the water; do cleaning work when the engine is working, high-speed rotation of the fan can be dangerous ; when the cleaning or replacement of the coolant, the machine should be parked on a level surface. At the same time before starting the engine to check the height of the cooling liquid level position (with water); check the engine oil level, Tai'an famous schools excavator, add oil; check fuel level (refueling); Check the hydraulic oil level (plus hydraulic oil); check the air filter is clogged; check cable; check the speaker is normal; check bucket lubrication; Check water separator of water and sediment in the oil temperature is too high A. What are the reasons: Hydraulic system? To maintain proper oil temperature, excavators school, usually in the range of 35 ~ 60 ℃ appropriate, the reasons causing high oil temperature are: (1) the system efficiency is too low, the capacity of small components, Tai'an best excavator school, high flow; bad (2) Fuel tank capacity, or heat; viscosity (3) oil is too large; (4) oil qualitative change bad, increase the viscosity of the oil, increase the resistance; good (5) cooling performance. Tai'an excavators school, Kerry and excavators school (online consultation), excavators school by 泰安嘉 and Heavy Machinery Co., Ltd. Taian Jia and Heavy Machinery Co., Ltd. (www.tajhzg.com/) is Tai'an, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Heavy leader in Kerry and the staff warmly welcome all inquiries negotiations to create Kerry and heavy industry a better future.
