Daily maintenance is very important for the excavator, which is a reliable guarantee for the performance, safety and service life of the excavator. Regular maintenance and explanation by professional service personnel. This article will explain some important matters in daily maintenance in combination with the knowledge points of engine and hydraulic system, which is only for reference.
1. Carefully read the operation manual of the excavator and correctly maintain and use the excavator with reference to the manual. Regular maintenance and the use of accessories recommended by the manufacturer are effective measures to prevent excavator failure. Keep in touch with local services to facilitate contact and consultation during maintenance and repair.
2. In daily maintenance and use, the engine is a key component that should be paid attention to. It is necessary to ensure good lubrication of the engine and cleaning of the air inlet to avoid high temperature. Therefore, it is necessary to pay attention to whether the retention of engine oil and antifreeze is within the standard range, and keep the air filter and radiator clean. To reduce accidental wear and high temperature deformation of the engine. High pressure common rail engine has higher requirements for diesel quality, and the harm of impurities and sulfides to the engine is particularly obvious.
3. The hydraulic system of excavator is a precision component with high working pressure, so the cleanliness of hydraulic oil is required to be very high. When using the breaker, the hydraulic oil should be kept clean as required. When the excavator is working under high load, the hydraulic oil temperature should be in an appropriate range to avoid poor low-temperature lubrication, deterioration and burns at high temperature. The excavator control system is complex, which belongs to the comprehensive control of electric and hydraulic pressure, and has a good match with the engine. Therefore, in addition to paying attention to the alarm display, it is necessary to observe whether the hydraulic system has leakage, noise, vibration, high temperature and smooth action.
