Here are 10 essential engineering machinery components and their functions:

• Drifter Bushing: Located in the front of the rock drill, it guides the drill steel during rock drilling. Example: Sandvik DP1500 Drifter Bushing (山特维克DP1500冲击器衬套, Втулка бурильной головки Sandvik DP1500).

• Feed Cylinder Seal Kit: Found in the hydraulic cylinder of the feed system, it prevents fluid leaks, ensuring smooth and powerful feeding of the drill rig. Example: Atlas Copco Boomer 282 Feed Cylinder Seal Kit (阿特拉斯科普柯Boomer 282推进油缸密封件, Комплект уплотнений цилиндра подачи Atlas Copco Boomer 282).

• Rotary Actuator: A hydraulic motor on the rock drill rig's boom, responsible for rotating the drifter or feed beam for precise positioning. Example: Epiroc SmartROC D65 Rotary Actuator (阿特拉斯科普柯SmartROC D65回转马达, Поворотный привод Epiroc SmartROC D65).

• Track Adjuster Assembly: Located in the excavator undercarriage, it maintains the proper tension of the track chain.

• Hydraulic Oil Cooler: A heat exchanger that cools the hydraulic fluid in the system to maintain optimal operating temperature.

• Drifter Piston: The main reciprocating component within a rock drill's drifter that generates the percussive impact force.

• Final Drive Seal: Found in the final drive unit, it seals in the gear oil and keeps out contaminants.

• Engine Water Pump: A component on the engine that circulates coolant to prevent overheating.
