The maintenance of hydraulic used excavator is very important. In order to meet the demand of various construction areas, hydraulic used excavators can be equipped with a variety of working device, such as mining, lifting , loading, damp, bulldozing, impact hammer and other operation equipments.
According to some statistics showing, hydraulic system failure of core used excavator is due to liquid pressure and oil contaminated. Excavator valve used in the hydraulic system components such as relative movement between fitting surface and fitting clearance will plug the gaps and holes and hinder the movement of the oil. For example, if impurities enter into hydraulic used excavator valve, it may damage the valve body and cause valve seal lax or ineffective. If oil sewage is overmuch, it will block filter and make system cycle prevented and higher temperature of system. Hydraulic driving system by the hydraulic pump of the engine power is passed to the hydraulic motor, cylinder actuators. It promotes the working device so as to complete all assignments. Therefore, hydraulic used excavator is the key of the maintenance of hydraulic system. You should keep hydraulic system and hydraulic oil clean.
Hydraulic used excavator should guarantee the reliability of hydraulic parts. You should ensure hydraulic parts not to be affected by water and dust pollution and prevent hydraulic oil leakage because each hydraulic part is based on precision component. You should check whether there is any fasten or loose phenomenon periodically. General used excavator should guarantee the empty start parking. The inertia hydraulic used excavator machine should ensure full feeding start parking. It' time stop if the abnormal situation appears, then finding the reason and handle it after it restarts. Hydraulic used excavator has a convenient maintenance. You can contact with the routine maintenance point on the ground and give play to the maximum availability. Remote information processing system is as a standard of hydraulic used Komatsu excavators and helps you to save fuel, reducing cost and achieving maximum profits.
You should do regular maintenance of hydraulic used track excavators. It is advisable to check each part of the impeller of wearing parts and abrasion of sheeting and ensure it is firm and reliable. You should clean the inside of hydraulic used excavator cavity in order to control machine in time. Before starting the operation, you must check the oil supply situation of lubrication station and whether the bearing cylinder oil seal is a lack of grease. You should check the major pars of electric control cabinet and ensure it is working correctly. The major parts of electric cabinet are including voltage, insurance, AC contactor, programmable controller, the main switch and light.
