How to use broken hammer to not damage excavato
2023 / 07 / 24
Modern economy and high-speed development, peopleundefineds industrial equipment is also continuously developing, in which the use of the breaking hammer is also very frequent, in which, for the crushing hammer factory, it is also very challenging, but the use of the crushing hammer and the excavator is still not well understood, In the following, Yantai Puxi Hydraulic Equipment Co., Ltd. provides you with the following: 1. Use a high-quality breaking hammer. The inferior crushing hammer is easy to solve due to the design, manufacture and inspection, and the failure rate is high, and the excavator is more likely to be damaged; 2. Suitable engine speed. As the crushing hammer has lower working pressure and flow requirements (such as 20-ton excavator, the working pressure is 160 to 180KG, the flow rate is 140 to 180 L/ MIN), the middle throttle can be operated; if the large-throttle operation not only does not increase the impact force, the hydraulic oil is abnormally heated, and the hydraulic system can also be damaged; 3. Correct butter position, frequency and quantity. The grease shall be supplemented in the straight state of the steel, and the grease shall be filled every two hours. If the lubricating grease is supplemented in the suspended state of the steel, the grease enters the striking chamber, and the abnormal high-pressure oil can be generated in the striking chamber to enter the hydraulic system, and the hydraulic pump is damaged; 4. Hydraulic oil quantity and pollution. Since the hydraulic oil pollution is one of the main reasons leadi
