Understanding the function of each part is key to effective maintenance. Here are 10 core engineering components for heavy machinery, primarily from Sandvik, Atlas Copco, and Epiroc:
1. Shank Adapter (Хвостовик): Installed in the Rock Drill/Drifter Head. Transmits striking power and rotation torque to the drill string. Example: Atlas Copco COP 1838 Shank Adapter.
2. Oil Separator (Сепаратор масла): Installed in the Air End/Compressor Tank. Separates oil mist from compressed air before discharge. Example: Atlas Copco XAS 186 Oil Separator.
3. Feed Cylinder (Цилиндр подачи): Installed on the Feed Beam of Drill Rig. Provides the necessary force to push the drill string into the rock. Example: Sandvik Ranger DX800 Feed Cylinder.
4. Hydraulic Pump (Гидравлический насос): Installed in the Main Power Pack. Converts mechanical power into hydraulic energy to drive actuators. Example: Epiroc SmartROC D65 Hydraulic Pump.
5. Drill Rod ( Буровая штанга): Part of the Drilling String. Connects the drifter to the bit, transmitting energy. Example: Sandvik Commando DC302R Drill Rod.
6. Tramming Motor (Ходовой двигатель): Installed in the Track/Undercarriage. Provides propulsion for self-moving drilling rigs. Example: Epiroc Boomer S2 Tramming Motor.
7. DTH Hammer (Пневмоударник): Installed at the Bottom of Drill String. Converts high-pressure air into impact energy for drilling. Example: Atlas Copco DM-45 DTH Hammer.
8. Seal Kit (Комплект уплотнений): Installed in Drifter/Hydraulic Cylinder. Contains all necessary seals to prevent fluid leaks. Example: Sandvik HLX5 Seal Kit.
9. Rotation Gear ( Вращающая шестерня): Installed in the Rotation Unit of Drifter. Manages the rotation of the drill string. Example: Epiroc COP 2550 Rotation Gear.
10. Filter Element (Фильтрующий элемент): Installed in the Hydraulic/Air/Oil System. Removes contaminants to protect sensitive components. Example: Atlas Copco XAS 97 Filter Element.
