DMB-220 Blue NOK Breaking Hammer Heat-Resistant And Pressure Resistant Oil
- Description
-
There may be differences between domestic breaker seal kits and NOK breaker seal kits in the following aspects:
Material Quality:
NOK: As a well-known Japanese brand, it usually uses high-quality rubber, polyurethane and other materials, which have good wear resistance, oil resistance, high temperature resistance and high pressure resistance. For example, under high temperature, high frequency and high pressure working conditions, the thermoplastic polyurethane has excellent performance, and the material has high stability and consistency. It can adapt to complex and harsh working environments and ensure the sealing effect and service life.
Domestic: The material quality of some domestic seal kits is also constantly improving, but there may be a gap with NOK in some performance indicators. Some domestic kits may use materials with relatively lower prices and perform slightly worse in terms of durability and stability under extreme working conditions.
Manufacturing Process:
NOK: It has advanced production processes and a strict quality control system. The manufacturing process is fine, the product has high dimensional accuracy, and the sealing structure is reasonably designed. For example, the structure of its sealing ring can maintain good sealing performance under different pressure and motion states. The product has strong consistency and reliability, and the rejection rate is relatively low.
Domestic: In recent years, the manufacturing process of domestic seal kits has made great progress, but on the whole, there may still be a certain gap with the international advanced level. The technological level of some domestic manufacturers is uneven. There may be deficiencies in product precision control and production stability, resulting in large fluctuations in the performance and quality of individual products.
Product Performance:
NOK: The product performance is stable and reliable, and it is outstanding in terms of sealing effect, wear resistance, and anti-aging performance. It can effectively prevent the leakage of high-pressure gas and lubricating oil inside the breaker, and at the same time prevent the entry of external impurities and moisture, reduce downtime caused by sealing problems, improve the working efficiency and reliability of the breaker, and extend the service life of the equipment.
Domestic: The performance of domestic high-quality seal kits is also constantly improving and can basically meet the daily use needs of breakers. Under normal working conditions, it can provide better sealing performance, but in some special working conditions with extremely high performance requirements or long-term high-intensity use environments, there may be a certain gap with NOK.
