What are the types of excavator breakers How to choose the right one
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.
