To prevent and control the problem of oil leakage of reducer, it should be improved and perfected from various aspects such as technology, production process, and quality control, and the specific measures are as follows:
1. The groove of the welded box steel plate is designed according to the thickness regulations, and the weld is inspected by MT and UT according to the standard requirements; The casting box is inspected by MT and UT flaw detection, so as to improve the casting process of the casting and improve the casting quality of the casting.
2. Optimize the scheme design, analyze and calculate the statics and dynamics of materials and structures under different loads for the stiffness and strength of the box, and analyze the modality of the box components to complete the rationality of the design.
3. Add a hardened shaft sleeve on the input and output shaft, grind the hardened surface, improve the surface roughness, ensure the hardness and roughness of the contact with the oil seal lip, and design to increase the special lubrication of the oil seal to avoid the early wear of the oil seal.
4. For the reducer with thin oil lubrication and mechanical seal, increase the oil return hole on the bearing seat, set the throttle sleeve according to the flow calculation requirements, and accurately distribute the flow rate of each lubrication point to avoid lack of oil or excessive oil supply due to uneven oil distribution.
5. The thread at the oil drain hole is changed to post-welding processing to ensure the fit and tolerance requirements of the thread; Increase the contact area between the end face of the screw plug and the oil drain hole to ensure good contact with the end face of the gasket.
6. Use a gasket between the observation hole cover plate and the box body of the reducer to increase the thickness of the sight hole cover plate and reduce the roughness of the joint part; For covers that require the use of plexiglass, steel backing plates are added to the plexiglass fastening bolts to prevent breakage of plexiglass.
7. Strict procurement requirements to ensure the quality of ball valves and seals, and avoid the occurrence of oil leakage in use due to the quality of such parts.
8. Strictly control the assembly quality requirements. Formulate reasonable assembly procedures, strictly implement assembly process steps, improve the assembly inspection process, formulate assembly and lubrication pipeline configurations, and make inspection records of the assembly process, so as to eliminate oil leakage caused by processing and assembly.
9. Control and inspect the processing and manufacturing process of each key component involved in the oil leakage of the reducer, and strictly implement the process control regulations.
10. Formulate a quality assessment system to improve the quality awareness of managers and employees.
11. Strengthen the guidance on the installation and use of the reducer on the user's site to avoid the occurrence of leakage caused by installation, use, overhaul and maintenance.
Honors and achievements gradually settle in the years, we pay more attention to a better tomorrow, and we will spare no effort to face the future. In the era of great changes in the increasingly fierce competition in the industry, we will abide by the development concept of "employees share the same destiny, enterprises and users develop together, and enterprises and society have the same responsibilities", with the principle of "based on the enterprise, serving customers, and dedication. The management tenet of "Society, Achievement of the Future" will go hand in hand with new and old friends, new and old customers, support each other, and create a brilliant tomorrow!
