Hitachi EX200 excavator parameter configuration Specification The working weight of the whole machine (kg)： 18824.1 Bucket capacity (m³)：0.8 Boom length (mm)： 5680 Stick length (mm) ：2910 Origin ：Japan Tonnage (ton) ：20 power ：traditional power bucket ：backhoe Manufacturer joint venture/import hitachi 200 excavator parts The ex200 is a crawler-type single-bucket excavator produced by Japan's Hitachi Construction Machinery Company. Its bucket capacity is divided into 0.8 cubic meters and 1.0 cubic meters. It has a larger working range and stronger digging force, the rotation and driving speed are increased, and the working noise is reduced, so it has higher productivity and technical and economic indicators.

The working principle of the excavator hydraulic swivel joint: When the excavator is working, its chassis and the upper operating body need to perform relative slewing motion. How to realize this movement that requires 360° rotation requires the core component of the excavator hydraulic swivel joint. When the excavator rotates, the hydraulic oil is delivered to the travel motor through the excavator hydraulic swivel joint, the hydraulic oil is connected from the main control valve to the internal cylinder, and the travel motor oil circuit is connected to the casing structure. The inner cylinder is cast with annular grooves (ie oil passages) from top to bottom, and the outer casing is also cast with small grooves corresponding to the grooves (used to install the rotary joint sealing ring). When the machine rotates, the casing is fixed, and there is relative movement between the inner cylinder and the casing (the cylinder rotates in the casing). Because the oil passage is circular, the machine can be turned arbitrarily within the circumference range, and the casing oil passage can be kept connected with the corresponding mandrel oil passage to realize continuous rotation. The central slewing joint for excavators consists of two parts: the inner cylinder and the outer shell, the shell is provided with a flange, which is fixed to the center of the slewing bearing, the shell is connected to the upper pipe, and the mandrel is connected to the lower pipe road.

Maintenance method of excavator radiator: 1. Avoid hot air recirculation during construction The filler near the radiator is often called a "sponge". But it cannot replace any "sponge". The needs of the excavator are mainly to avoid the recirculation of hot air, so corrosion resistance, temperature resistance and air permeability must be insufficient. That is, when the cold air drawn in from the front of the excavator radiator rises in temperature and enters the rear of the radiator (engine compartment), it cannot return to the front of the excavator radiator. When the hot gas returns to the radiator, the heat dissipation of the system is reduced, the temperature of the oil and water increases, the engine does not work properly, and may be damaged prematurely. Therefore, when operating a small hydraulic excavator below 30,000, it is impossible to ignore the observation and correction of the "sponge" near the radiator, and it is necessary to replace a part in time.

The komatsu excavator undercarriage parts carries the full weight of the excavator and is responsible for the driving function of the excavator. The main damage form is wear, which is concentrated in the following contact parts: the outer surface of the drive wheel teeth and the track pin sleeve: the guide wheel and the track link raceway surface of the track; the roller and the track track link raceway The surface of the carrier roller and the track link of the track; the contact surface of the track pin and the pin sleeve; the track shoe and the ground, etc.
