The key applications and advantages of finished honed tubing in the hydraulic system are mainly reflected in the following aspects:
1. High precision and stability
Honing tubes have extremely high dimensional accuracy and surface finish. The tolerance range is usually H7, H8, H9, and the surface roughness can reach Ra 0.4 μm. They are suitable for hydraulic systems with extremely high precision requirements. This high-precision feature enables honing tubes to achieve more stable fluid control in hydraulic systems, reducing leakage and wear problems caused by dimensional deviations or surface roughness.
2. Excellent wear resistance and durability
The honing process significantly enhances the wear resistance and fatigue resistance of the pipe by removing surface defects and forming a residual stress layer. Research shows that the surface hardness after honing treatment can reach HV≥4°, and the fatigue strength can be increased by approximately 30%. This characteristic enables the honing tube to perform well in high-pressure and high-impact load hydraulic systems, thereby extending the service life of the system.
3. Good sealing performance
The inner surface roughness of the honing tube is low, which can provide better sealing performance, reduce the leakage of hydraulic oil, and thereby improve the efficiency and safety of the system. In hydraulic systems, sealing performance directly affects the stability and reliability of the system. Therefore, honing tubes have obvious advantages in this aspect.
4. It is applicable to various complex working conditions
Honing tubes are not only suitable for standard hydraulic systems, but also widely used in fields such as automotive manufacturing, military equipment, construction machinery, and metallurgical pickling and galvanizing equipment. Its high precision and high wear resistance enable it to maintain stable operation in harsh environments such as high temperature, high pressure and impact loads. For instance, in a car engine, honing tubes are used to transmit power and ensure an efficient fit between the piston and the crankshaft.
5. Enhance system efficiency and reduce maintenance costs
Due to the high precision and wear resistance of the honing tubes, the friction and wear in the hydraulic system are significantly reduced, thereby lowering energy consumption and maintenance costs. In addition, the processing cost of honing tubes is relatively low, but it can significantly improve the overall performance and service life of the system. This "Heng instead of research" technical solution has been widely applied in hydraulic systems.
6. Combination of customization and standardization
Honing tubes can be customized according to customer requirements to meet the special needs of different hydraulic systems. Meanwhile, its manufacturing standards (such as GB3639-83, ASTM A513, etc.) ensure the standardization and consistency of the products, facilitating their promotion in different industries and application scenarios.
7. Environmental Protection and Sustainability
The improved honing oil cylinder tube, through optimized structural design and surface treatment (such as high-speed gas-sprayed ceramic hardening), has reduced the thermal processing procedures, lowered energy consumption and scrap rate, and meets the requirements of environmental protection and sustainable development.
Summary
The key applications of finished honed tubing in the hydraulic system lie in its high precision, high wear resistance, good sealing performance and adaptability to complex working conditions. These characteristics make it an indispensable core component in hydraulic systems and it is widely used in multiple fields such as automobiles, military, construction machinery, and metallurgy. By choosing honing tubes, the hydraulic system can not only achieve higher precision and stability, but also significantly extend its service life, reduce maintenance costs and improve overall efficiency.
