OEM Manufacturer Durable High Frequency HB20G Hydraulic Rock Breaker Main Body
The hydraulic breaker main body is the hydraulic hammer's main component, primarily consisting of the front, middle, and back cylinders.
The front cylinder (assembly): consists of the front cylinder, front sleeve, rear sleeve, front sleeve pin, rear sleeve pin, flat pin, cross pin, and grease nipple.
The middle cylinder (assembly): includes the middle cylinder bore, piston, piston sleeve, plug, direct drive, accumulator, oil seal, and frequency adjusting valve. The middle cylinder is the piston's movement space, where it reciprocates under the action of hydraulic fluid. The accumulator stores and releases energy, buffering impact and vibration. The frequency adjusting valve adjusts the piston's movement frequency.
The back cylinder (assembly): typically includes the back cylinder and gas storage chamber.
Core Component Functions
Piston: Made of high-strength 42CrMo alloy steel.
Control Valve Assembly: Includes the main valve and spool valve, with key components including the valve core, valve sleeve, and frequency modulation spring.
Accumulator: Typically a nitrogen chamber.
