In the field of engineering construction, Hitachi excavators have become indispensable assistants in many construction projects due to their excellent performance and reliability. However, as for any mechanical equipment, effective maintenance is crucial for maintaining Hitachi excavators in optimal working condition and extending their service life. Below is a detailed introduction to the daily maintenance of Hitachi excavators. 1. Drink the engine. When the temperature of the coolant drops below 10 ° C, the glow of the hitachi excavator engine automatically starts the heating process. The preliminary heating indicator lights up, warning the operator to warm up the engine. The start of the engine is possible only after the completion of the preliminary heating, which reduces wear when starting and provides smooth operation. When the temperature of hydraulic oil is lowered below 0 ° C, the temperature sensor of hydraulic oil supplies a signal to the controller, which triggers a DC electric motor into a given speed of rotation for pre -heating the hydraulic oil and ensuring the proper operation of the hydraulic system. 2. Carrying of the hydraulic system level of oil and filter: regularly check the level of hydraulic oil to make sure that it is within normal limits. This is the key to the stable operation of the hydraulic system. It is also necessary to regularly replace the hydraulic oil filter in strict accordance with the requirements of the operating and maintenance manual. If the filter is not replaced for a long time, it will be clogged, which will lead to pollution entering the hydraulic system, which will lead to wear of hydraulic components and reduce productivity of the entire system. Sealing: thoroughly check the pipelines, connections and cylinders of the hydraulic system for the presence of oil leaks. If leaks are detected, tighten the compound in a timely manner or replace the seals to prevent a leakage of hydraulic oil and prevent the normal operation of the equipment due to a lack of oil. 3. Correlation with lubrication The choice of lubricant: to lubricate the key details, such as the front connecting pin, the rotary bearing, the gear crown of the rotary mechanism and the central rotary hinge, use the Hitachi recommended lithium with outfit properties. This lubricant has good resistance to pressure and wear resistance, which allows you to effectively reduce the friction coefficient between moving parts and reduce wear. Regular replenishment: regularly check and replenish the lubricant depending on the frequency of use and operating conditions of the equipment. For example, it is recommended to lubricate the pins of the working body after each working shift; The rotary support should be lubricated every 250 hours to guarantee the constant presence of lubrication in all components and extend their service life. 4. The air filter service is the air filter function to prevent dust and other contaminants in the engine and the deterioration of its operation. Regular cleaning or replacing the air filter is extremely important. During operation in conditions of increased dusting, the frequency of examinations and maintenance should be increased. If the filter is strongly clogged, it should be immediately replaced to ensure smooth air intake, effective combustion of fuel, increased fuel economy and prevent increased engine wear due to excessive pollution. 5. The service of the cooling system cleaning and removal of the scrap: regularly clean the cooling system to prevent the accumulation of scale and pollution in the cooling system and the deterioration of heat transfer. You can use a special cleaning tool for the cooling system using the specified method and proportion. Replacement of coolant: when replacing the coolant, the car must be installed on a flat surface to ensure safe operation. In this case, the coolant and the anti -corrosion agent should be selected in strict accordance with the standards, and the ratio of the components should also be observed. In winter, special attention should be paid to the addition of antifreeze in order to prevent the freezing of the coolant and damage to the cooling system. 6. Care of the electric system carefully check the integrity of electrical circuits, make sure that there is no damage, wear, short circuits, etc., as well as that the power plug is reliably inserted into the outlet. Regularly check the level of electrolyte in the battery to make sure of its normal level. If the level is insufficient, share distilled water. In addition, check the electrodes of the battery for corrosion. In the event of its presence, immediately clean them and apply a protective lubricant to ensure stable power supply of the electrical system and avoid failures in power supply affecting the normal operation of the equipment. 7. Care the teeth and levers of the bucket. The teeth and hilt of the bucket are components directly involved in the process of earthwork, and their condition directly affects the effectiveness and results of digging. Spend the teeth of the bucket for wear regularly. Strong wear of teeth increases the resistance of digging, fuel consumption and can even reduce performance. Replace the teeth immediately. Also inspect the bucket hilt for the presence of cracks, deformations and oil leaks. If there are any malfunctions, immediately repair or replace them to ensure safe and reliable operation.
