When we want to maintain the flexibility and efficiency of Shandong excavators in high-intensity and high-frequency construction tasks, effective management of accessories is crucial. Let me tell you about the principles of using Shandong excavator accessories. The precise combination of accessories determines the comprehensive performance of the machine. For example, the mechanical parts and the drive control part are complementary, and the electronic control part is used to drive and coordinate the orderly work of each mechanical part. The situation of the mechanical part is fed back to the electronic control part through the electronic part, and then Coordinate the work of Shandong excavators more effectively to achieve higher work efficiency. 　　 First of all, we should pay attention to the principle of complementarity. At present, there are many types of accessories on the market, and there are many pure counterfeit and shoddy products. These counterfeit and shoddy products are very similar in appearance to regular products and are difficult to distinguish, but the internal structure and quality are completely different. Use these fake and shoddy products Will cause serious damage to the equipment. Furthermore, pay attention to the principle of normative use of accessories. In this regard, users are required to maintain various components during the trial period of the equipment, so as to reduce abnormal losses and reduce cost input. Precision parts such as fuel injector assembly, delivery valve assembly and plug assembly, etc., have a small fit gap, and a little rust will reduce the performance or even scrap. 　　 For new parts that are not in use temporarily, do not open the original packaging, and store them in a ventilated and dry place. Used parts should be cleaned with clean diesel oil to remove carbon deposits and other dirt. After being assembled in pairs, put them in a container with clean engine oil. The height of the oil level should be such that the parts do not expose the oil surface to contact with air. For shaft parts, including unused new shafts or removed old shafts, the surface finishing parts should be coated with grease (butter) and wrapped, and stored in a dry and ventilated place. The longer shaft should be placed horizontally or vertically. Do not place it at an angle to avoid deformation.
