Introduction to the matters needing attention and use scope of hydraulic wrench
The hydraulic wrench is usually composed of the body of the hydraulic torque wrench, the pump station for the hydraulic torque wrench, the double high-pressure hose and the high-strength heavy-duty sleeve. Hydraulic wrenches are divided into two series: driven hydraulic wrenches and hollow hydraulic wrenches. The driven hydraulic torque wrench relies on the drive shaft to drive the corresponding specification sleeve to achieve the pre-tightening of the nut. As long as the torque range allows, the corresponding high-strength sleeve can be replaced to complete the bolts of different specifications. , The scope of application is also very wide. The hollow hydraulic torque wrench is to be equipped with a transition sleeve. So what are the precautions for hydraulic wrenches?  　　 Notes on hydraulic wrench  1. The connecting hose should be in a free state, and should not be coiled into a circle with a diameter less than 500mm. 2. Lubricating grease should be applied to the connecting pins and movable parts of the hydraulic wrench to reduce torque loss due to friction. 3. The hydraulic system must not be connected by hand when working. 4. After removing the quick connector, the exposed part of the connector must be covered with a plastic cover. 5. The working oil needs to use ordinary hydraulic oil, which is equivalent to 20 # engine oil. The working oil in the system must be replaced and cleaned every year. 6. The temperature of the hydraulic wrench is too high for long-term use, which is not conducive to normal work. At this time, it is necessary to take cooling measures or stop using it to reduce the damage of the hydraulic wrench. At the same time, the pressure of the hydraulic wrench should be adjusted according to the actual working conditions, and it should not be overloaded to avoid safety accidents. 7. The hydraulic wrench is based on the quality of hydraulic oil. All the hydraulic oil should be protected from contamination during use. Check and eliminate the hydraulic oil failure in time, and pay attention to cleaning once every two months during use. 8. In the process of operation, if the wrench is weak or loose, it needs to be repaired in time to tighten the loose bolts. At the same time, it should be repaired in time to replace the damaged parts.  　　 Use range of hydraulic wrench  Hydraulic wrenches are used in a wide range of applications; in the construction, maintenance, and repair work of marine engineering, petrochemical, wind power, hydropower, thermal power, mining, machinery, steel mills, rubber, pipelines, and other industries, hydraulic torque wrenches are suitable for large-size bolts The installation and disassembly are both important tools; they are irreplaceable with other tools. Not only is it convenient to use, but the torque provided is very accurate, with a torque repeatability of about ± 3%. The above content is related knowledge about the matters needing attention and use scope of hydraulic wrench introduced to friends. When operating a hydraulic wrench, the operator needs to pay attention to some details, and judge whether the machine is faulty according to the senses and daily work experience. Reducing potential safety hazards can bring more benefits. Rolling mill oil film bearing technology, is a system engineering technology, at the same time, is also a multidisciplinary field of comprehensive engineering technology, its development speed and the formation of supporting capacity, from one side reflects the development speed of China's industry and the level reached. This paper briefly discusses several main aspects such as operation technology, manufacturing technology, testing technology, theoretical research, product development, and complete set of capabilities Mill Tapered Bearings,High Speed Bearing,Waterproof Bearing,High Speed Friction Resistant Bearing Hebei Fangqiang bearing manufacturing Co., LTD , https://www.fangqiangbearing.com
1. Operation technology, including a complete set of knowledge and skills such as storage, cleaning, installation, commissioning, operation, maintenance, diagnosis, and management of rolling mill oil film bearing parts. The correct application of running technology is a reliable guarantee for the safe operation of bearings.
In the early 50s, only the reversible rolling mill of Anshan Iron and Steel Cold Rolling Mill in China was equipped with oil film bearings. Its operation and management are carried out in full accordance with the relevant regulations of the Soviet Union. In the traditional process, the rolling pressure is not large, the rolling speed is low, the lubrication system is also very simple, and the operating technology level is relatively low. However, in actual operation, the work of the relevant management, technical personnel and operators is very serious, strictly in accordance with the regulations, and has accumulated experience in use and maintenance.
