In engineering construction, excavator breaker hammers are powerful tools that can break hard rocks and concrete, etc. Proper operation of the breaker hammer can improve work efficiency, extend service life and reduce maintenance costs. Second-hand dealers play an important role in the use and trading of breaker hammers.
Before operation, carefully check the various parts of the breaker hammer, such as the drill rod, piston, nitrogen chamber, etc., to ensure that there are no cracks, bends or excessive wear, the piston moves flexibly, and the nitrogen chamber pressure is normal. For second-hand breaker hammers, second-hand dealers will conduct a comprehensive inspection and evaluation when purchasing, judge the degree of wear and remaining service life, and provide reference for buyers. At the same time, check whether the hydraulic pipeline connection is firm and leak-free, and ensure that it is correctly connected to the excavator hydraulic system. When choosing a breaker hammer, it is necessary to select the appropriate specifications and power according to the excavator model and work requirements. Too large may cause overload, and too small may not meet the requirements. Second-hand dealers can recommend suitable second-hand breaker models according to the specific needs of customers to help customers find equipment with good performance within the budget. It is also necessary to consider the working environment and the nature of the crushing object and choose the appropriate type. In addition, it is necessary to adjust the excavator settings, adjust the hydraulic system pressure and flow according to the weight of the breaker and the working requirements, and select the working mode suitable for the crushing operation.
During the operation, the breaker should be installed correctly, firmly mounted on the excavator arm, and connected with a special connecting pin and locking pin to prevent it from falling off during operation. Second-hand dealers can provide installation guidance and technical support to ensure that customers install the second-hand breaker correctly to avoid safety problems and equipment damage. When connecting the hydraulic pipeline, connect the oil inlet pipe and the oil return pipe in the correct direction and sequence. When starting, start the excavator engine first, let the hydraulic system preheat, ensure that the hydraulic oil temperature reaches the normal working range, then open the breaker control valve, slowly operate the operating lever, so that the breaker gradually contacts the crushing object, pay attention to control the force, and avoid impact. When controlling the crushing force, adjust it reasonably according to the hardness and thickness of the crushing object. For harder objects, the force can be appropriately increased, but not excessively, so as not to damage the breaker and excavator. Second-hand dealers can provide recommendations on the striking force based on the use history and performance characteristics of the breaker to help customers master the operating skills. Use intermittent striking to prevent overheating and damage caused by continuous striking. The impact angle should be adjusted according to the shape and position of the crushed object. Generally, it should be struck vertically to obtain the best effect. It can be adjusted appropriately for inclined or irregular objects, but it should not be tilted too much. During operation, the operator should wear personal protective equipment such as safety helmets, protective glasses, earplugs, etc., keep the operation area clean and safe, avoid obstacles and people approaching, pay attention to the surrounding environment, and stop the operation immediately when the breaker makes abnormal noise, vibration, oil leakage, etc., check the cause of the fault and repair or replace the parts. Second-hand dealers can provide troubleshooting and maintenance services to ensure the normal operation of the second-hand breaker.
After operation, the surface and various parts of the breaker should be cleaned in time to remove impurities such as dust, dirt and oil. It can be cleaned with a high-pressure water gun or detergent, but water cannot enter the interior. Check whether the breaker parts are damaged or worn, and repair or replace them in time for serious ones. Second-hand dealers can provide maintenance and replacement parts services to ensure the performance and reliability of the second-hand breaker. At the same time, check whether the hydraulic pipeline is leaking, repair the leaking part, check the quality and level of the hydraulic oil, and replace or add it in time.
In short, the correct operation of the excavator breaker is crucial to engineering construction. Second-hand dealers can provide customers with professional advice and services in the selection, installation, operation and maintenance of breaker hammers, helping customers to better use breaker hammers, improve work efficiency and reduce costs. When choosing a second-hand breaker hammer, customers should choose a reputable second-hand dealer to ensure that they purchase equipment with good performance, reliability and durability.
