Understanding Key Components of Your Hydraulic System

Knowing the function of different parts is crucial for proper maintenance. Here are a few examples:

• Piston Pump (Pусский: Поршневой насос) - This component converts mechanical energy into hydraulic energy. It is located in the main pump assembly.

  Example: Sandvik Pantera DP1500 Hydraulic Piston Pump.

• Swing Motor (Pусский: Поворотный двигатель) - A hydraulic motor that rotates the machine's superstructure. It is located in the cab's base.

  Example: Atlas Copco SmartROC D65 Swing Motor.

• Final Drive (Pусский: Бортовой редуктор) - This is the last gear reduction in a machine's drivetrain, used to move the tracks. It is located at the rear of the track frame.

  Example: Epiroc FlexiROC T45 Final Drive.

• Hydraulic Cylinder (Pусский: Гидравлический цилиндр) - A linear actuator that uses hydraulic fluid to create force in a straight line. Found in the boom, arm, and bucket.

  Example: Sandvik Ranger DX800 Hydraulic Cylinder.

• Track Roller (Pусский: Опорный каток) - These rollers support the weight of the machine and guide the track. They are located on the underside of the track frame.

  Example: Epiroc PowerROC T50 Track Roller.

• Hydraulic Control Valve (Pусский: Гидравлический распределитель) - This valve directs the flow of hydraulic fluid to various parts of the machine. It is typically located near the main pump.

  Example: Atlas Copco Boyles C6C Hydraulic Control Valve.

• Engine Oil Cooler (Pусский: Масляный радиатор двигателя) - A heat exchanger that removes heat from the engine oil. It is located near the engine's radiator.

  Example: Sandvik Commando DC302R Engine Oil Cooler.

• Boom Cylinder (Pусский: Цилиндр стрелы) - A type of hydraulic cylinder that lifts and lowers the main boom of an excavator. It is located at the base of the boom.

  Example: Atlas Copco Cobra Pro Boom Cylinder.

• Slewing Bearing (Pусский: Опорно-поворотное устройство) - A large bearing that connects the superstructure to the undercarriage, allowing for rotation. It is located at the machine's center.

  Example: Epiroc Boomer L2C Slewing Bearing.

• Pilot Pump (Pусский: Насос управления) - A small pump that provides pressure to operate the main control valves. It is often part of the main hydraulic pump assembly.

  Example: Sandvik DD210 Pilot Pump.
