A hydraulic breaker, commonly used in construction, mining, and demolition, operates by converting hydraulic energy into mechanical impact force, enabling it to break through hard materials like rock and concrete. The working principle of a hydraulic breaker can be summarized in the following steps: 1. Hydraulic Pump Provides Pressure The hydraulic system's core component is the hydraulic pump, which derives power from an excavator or other primary machine. The pump pressurizes hydraulic oil and sends it to the breaker, providing the necessary power for the breaking process. 2. Hydraulic Oil Drives the Piston High-pressure hydraulic oil enters the breaker’s main cylinder, driving the internal piston downward. The speed and force of the piston movement depend on the pressure and flow rate of the hydraulic oil. 3. Piston Generates Impact Force As the piston moves downward, it strikes the impact head (chisel or hammer) at high speed, generating a powerful impact force. This force is transferred through the chisel to the material being broken, such as rock or concrete, causing it to fracture. 4. Hydraulic Oil Returns After the piston completes the impact, the hydraulic oil flows back to the reservoir, and the piston returns to its initial position, ready for the next impact. This process repeats cyclically, producing continuous impact force. 5. Chisel Breaks the Target Material The chisel, under the force of the repeated impacts, directly contacts and strikes the target material, such as rock or concrete. The repeated high-intensity impacts gradually break the material into smaller pieces. 6. Energy Control and Adjustment The breaker typically includes an energy control valve, allowing the operator to adjust the flow and pressure of the hydraulic oil. This controls the size and frequency of the impact force, making it adaptable to different material hardness and working conditions. Key Components - Hydraulic Pump: Provides high-pressure hydraulic oil. - Piston: Driven by hydraulic oil, generates impact force. - Chisel: Directly contacts the target material and transfers the impact force. - Control Valve: Adjusts the flow and pressure. The advantages of hydraulic breaker are its strong impact force and high efficiency, suitable for crushing operations on hard materials.  

1.Working Principle The hydraulic breaker mainly converts hydraulic energy into mechanical energy. Through the high-speed movement of the piston, a powerful impact force is generated, which acts on the drill rod. The drill rod then transmits the impact force to the working object (such as rock, concrete, etc.) to break it. 2.Structural Components ①Housing: Protects internal components and is usually made of high-strength steel with good impact resistance and wear resistance. ②Piston: It is the key component for generating impact force and moves at high speed under the push of hydraulic oil. ③Drill rod: Transmits the impact force of the piston to the working object. Its material and design affect the breaking efficiency and service life. ④ Control valve: Controls the flow direction and pressure of hydraulic oil to realize various actions of the hydraulic breaker. ⑤ Accumulator: Stores hydraulic energy and releases it quickly when needed to increase the striking force and striking frequency. 3.Selection Points ①Select the appropriate hydraulic breaker model according to engineering needs, considering factors such as the hardness, volume, and working environment of the working object. ②Match the hydraulic system parameters of the host machine such as excavators, including flow rate and pressure, to ensure that the hydraulic breaker can work normally and perform at its best. ③Pay attention to the quality and brand of the hydraulic breaker. Select products with good reputation and reliable quality to reduce maintenance costs and improve work efficiency. 4. Maintenance ① Regularly inspect various components of the hydraulic breaker, such as drill rod, piston, seals, etc., and replace them in time if wear or damage is found. ② Keep the hydraulic breaker clean to prevent dust and debris from entering and affecting working performance. ③Use the hydraulic breaker correctly and avoid improper operations such as excessive striking and empty striking to reduce damage to the equipment. ④Regularly replace hydraulic oil and filters to ensure the cleanliness and normal operation of the hydraulic system. 5. Safety Precautions ①Operators should undergo professional training and be familiar with the operation methods and safety regulations of the hydraulic breaker. ②When using the hydraulic breaker, ensure the safety of people around and set up warning signs. ③Avoid using the hydraulic breaker in flammable and explosive places to prevent danger. ④Check whether the connection parts of the hydraulic breaker are firm to prevent accidents caused by falling off during work.

The 16th China Beijing International Construction Machinery, Building Materials Machinery and Mining Machinery Exhibition and Technical Exchange Conference (BICES) was successfully concluded on September 23, 2023. Established in 1989, BICES is the first professional construction machinery exhibition certified by the Union of International (UFI) in China. After more than 30 years of development, BICES has remained dedicated to showcasing cutting-edge technologies, innovative products, and modern construction methods within the industry, catering to the diverse needs of clients and providing business opportunities worldwide, particularly in emerging markets such as the Belt and Road. Furthermore, it serves as a platform for dialogue with industry leaders and highlights the high-quality development of the engineering sector by fostering a value exchange environment.
