The types of hydraulic breakers for excavators are diverse and can be classified according to different criteria. Here are some common classification methods and suggestions for choosing the right breaker:
1. Operation Mode: Divided into handheld and machine-mounted categories.
2. Working Principle: Can be divided into full hydraulic, hydraulic-pneumatic combined, and nitrogen blast types. The hydraulic-pneumatic combined type, which relies on the expansion of hydraulic oil and compressed nitrogen to drive the piston, is the most common.
3. Valve Structure: Hydraulic breakers are divided into built-in valve and external valve types.
4. Feedback Method: Classified into stroke feedback and pressure feedback breakers.
5. Noise Level: Divided into low-noise and standard noise breakers.
6. Casing Shape: Classified into triangular and tower-shaped breakers based on the casing form.
7. Casing Structure: Classified into clamp plate and box frame breakers based on the casing structure.
When choosing the right hydraulic breaker for an excavator, consider the following aspects:
- Excavator Weight and Bucket Capacity: The selected breaker should match the weight and bucket capacity of the excavator to ensure safety and efficiency.
- Working Flow and Pressure: Ensure that the breaker's flow requirements match the output flow of the excavator's auxiliary valve to avoid overheating of the hydraulic system or reducing the lifespan of components.
- Breaker Structure: Choose different structural designs such as triangular, right-angle, or silent types based on the working environment and needs, to obtain better protection, reduce noise, and vibration.
- Hydraulic Breaker Model: Understand the meaning of numbers in the model, which may indicate the excavator's weight, bucket capacity, or the breaker's impact energy, to select the appropriate model.
In summary, when choosing a breaker, consider the excavator's model, tonnage, working environment, and required breaking force to ensure that the selected breaker's performance parameters match the requirements of the excavator's hydraulic system.
