Overview Frequently excavator excavator construction include the power plant Tai'an best schools excavator, equipment, excavator slewing mechanism schools, steering mechanism, transmission, running gear and auxiliary facilities. From the exterior, the excavator, the upper turret by the working device Tai'an schools excavator phone, running gear consisting of three parts. According to its structure and purpose can be divided into: Crawler, tire type, walker, hydraulic, semi-hydraulic, full swing, non-full rotation, general-purpose, special type, articulated, telescopic boom and other types. Working device is a direct means to complete the mining task. It consists of the boom, arm and bucket three parts hinged together. Landing boom, arm and bucket rotation are used telescopic double-acting hydraulic cylinder reciprocating control. In order to meet the various needs of different construction jobs, excavators can be equipped with a variety of work equipment, such as digging, lifting, loading, smooth, clamps, dozer, hammer, and other work tools. Rotary and walking device is a hydraulic excavator body, the upper part of the turret with a power plant and transmission. The engine is the power source of the excavator, they use diesel to be at a convenient venue, it can also be switched to the electric motor. Transmission through the hydraulic power of the engine is transmitted to the hydraulic motor, hydraulic cylinders and other actuators, to promote the work means action to complete the various operations of the leakage of hydraulic oil cylinder rod reason ① trauma - hard object collisions, squeeze and the slump was rolling friction or other injuries; ② surface erosion - chemical substances (chlorides, sulfides, acid, gas, etc.) contamination in the plating surface, appear white spots; ③ paint - so dust ring with a U-shaped seal edge bite occurs; ④ bending - improper operation or abnormal use due; ⑤ stretch - improper operation or abnormal use, resulting in a tapered rod screw into place. Even nuts off. ⑥ welding sparks --1 Direct Indirect welding sparks flying sparks caused by welding; ⑦ shock spark - wire strike; ⑧ dust - not a long time, they did not carry out proper maintenance, the piston rod surface stickiness due to stolen goods (prior to use and not cleaning or washing is not clean, a working longer).
