• 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

  Many masters will doubt such a question, why the broken hammer bought at the same time is used by others for a longer time than themselves, in fact, such a result is not unexpected, the following Yunnan engineer broken hammer Xiao Li will share with you the maintenance, installation of broken hammer skills and details. First: venue is key Choose a clean, clean, flat site, be sure to stay away from dust, debris, put the hammer on two pieces of wood. Remember to clean the dirty hoses and connectors in time. It is recommended to use special cleaning oil for better effect. Second: installation steps (1) After the host and the site are ready, the first step is to align the boom of the host with the center of the crushing hammer pin. Next, carefully lower the host connecting rod, align the pin hole on the boom with the pin hole on the crushing hammer support, and then insert the pin shaft. (2) Install the stop ring, align the bolt hole and insert the bolt. Cross tighten the two nuts. Note that if the stop ring is too tight with the nut, it will shorten the life of the bolt or cause it to become loose. (3) Shut off the engine, if there is pressure in the hydraulic tank must be released completely. Turn the closure valve mounted on the end of the main boom 90 degrees to prevent hydraulic oil from flowing out. Nitrogen pressure will cause the rod to fly out. Do not operate near the rod. (4) Loosen the tube plug on the crushing hammer hose and the tube joint cover on the front end of the main boom, and then connect the high pressure and low pressure oil hose to these joints respectively. There will be a small amount of hydraulic fluid, so find a container. Third, disassembly steps (1) The disassembly steps of the crushing hammer are opposite to the installation. After disassembly, plug the hose on th

  Crushing hammer may be in addition to the bucket, excavator is the most commonly used tools, and with the hammer, excavator work to make more money, but we also know that "shooting" is very harmful to excavator itself, especially incorrect operation. Precautions for operation are as follows (1) When using the crushing hammer each time, first check whether the high pressure or low pressure oil pipe of the crushing hammer is loose; At the same time, for the sake of caution, we should always check whether there is oil leakage in other places, so as to avoid a oil pipe falling off due to vibration and thus failure. (2) In the crushing hammer operation, the drill rod should always be vertical to the surface of the broken object. And make the rod is pressed to be broken object, broken should immediately stop crushing hammer work, in order to prevent air play. Continuous aimless impact will cause damage to the precursor of the crushing hammer and loosening of the main bolt, and can hurt the host itself in serious cases. (3) when crushing, do not use shaking rod, otherwise the main bolt and rod may be broken; Do not make the crushing hammer fall down quickly or hit hard stones, which will damage the crushing hammer or main engine due to excessive impact. (4) Do not crush in water or mud. In addition to the rod, other parts of the crushing hammer body should not be immersed in water or mud, otherwise the piston and other parts with similar functions will cause premature loss of the crushing hammer due to the accumulation of mud. (5) when breaking especially hard objects, should start from the edge, do not continuously beat more than 1min at the same point, in order to prevent rod burning or hydraulic oil overheating. (6) Do not use the protectio
