Understanding where each part fits is crucial. Here are some examples of the components we supply and their applications on real-world equipment:
Piston Assembly: This component is at the heart of the engine's combustion process, converting the energy from combustion into mechanical motion. It is located in the engine block. A real-world example is the Sandvik DP1500i Piston Assembly （活塞组件） （поршневой узел）.
Flush Head Kit: Used in rock drilling applications, this part directs air and water to the drill bit to flush out cuttings and keep the drill hole clean. It is located at the front of the rock drill. An example is the Atlas Copco ROC D7-11 Flush Head Kit （冲洗头套件） （комплект промывочной головки）.
Shank Adapter: This is the connection point between the rock drill and the drill steel, transmitting the percussive and rotational energy to the drill string. It is located at the front of the rock drill. An example is the Epiroc Boomer L2D Shank Adapter （钎尾） （хвостовик）.
Rotary Actuator: This device uses hydraulic pressure to produce rotational motion, often found in equipment like pipe handlers or boom positioning systems. It is located on the boom or drilling unit. An example is the Sandvik DD320-40 Rotary Actuator （旋转执行器） （поворотный привод）.
Cylinder Seal Kit: A set of seals used to repair and maintain a hydraulic cylinder, preventing fluid leaks and maintaining pressure. They are located inside hydraulic cylinders. An example is the Atlas Copco Boomer E2C Cylinder Seal Kit （油缸密封件） （комплект уплотнений цилиндра）.
Track Shoe: The part of the track chain that makes contact with the ground, providing traction for excavators and bulldozers. It is located on the undercarriage. An example is the Caterpillar D11T Track Shoe Assembly （履带板） （гусеничный башмак）.
Engine Oil Filter: Filters the engine oil to remove contaminants and debris, ensuring the longevity of the engine's internal components. It is located on the engine block. An example is the Cummins N14 Engine Oil Filter （机油滤清器） （масляный фильтр двигателя）.
Main Control Valve: The heart of the hydraulic system, this valve directs hydraulic fluid flow to various actuators and cylinders to control the movement of the machine's attachments. It is located in the hydraulic system manifold. An example is the Hitachi Zaxis 200 Main Control Valve （主控阀） （главный управляющий клапан）.
Final Drive Assembly: This component reduces the speed and increases the torque from the hydraulic motor to turn the sprockets and drive the tracks. It is located on the undercarriage at the end of the track frame. An example is the Komatsu PC200 Final Drive Assembly （终传动） （бортовой редуктор）.
Boom Pin: A large steel pin used to connect the boom of an excavator or crane to the machine's body, allowing for pivotal movement. It is located at the base of the boom. An example is the Volvo EC480D Boom Pin （大臂销） （палец стрелы）.
