What is hydraulic oil used for?
Hydraulic oil is an indispensable working medium in the hydraulic system, and its performance directly affects the operating efficiency and service life of the equipment. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the functions, types, application scenarios and market trends of hydraulic oil, and use structured data to help readers quickly grasp the core information.
1. The core role of hydraulic oil
Hydraulic oil mainly performs the following functions in hydraulic systems:
| Function | illustrate |
|---|---|
| energy transfer | As a medium to transmit pressure and power, driving mechanical parts to move |
| Lubrication protection | Reduce friction and wear between metal parts and extend equipment life |
| Cooling and heat dissipation | Absorb heat generated by the system to maintain normal operating temperature |
| Sealed and leak-proof | Fill gaps to prevent liquid leakage in high-pressure environments |
| Anti-corrosion and anti-rust | Inhibits moisture and air corrosion on metal parts |
2. Common types and characteristics of hydraulic oil
According to differences in composition and performance, hydraulic oils are mainly divided into the following categories:
| type | Main ingredients | Applicable temperature | Typical applications |
|---|---|---|---|
| Mineral oil type | petroleum based refining | -20℃~80℃ | General construction machinery |
| Synthetic | Esters/polyalphaolefins | -40℃~150℃ | Aviation and polar equipment |
| Biodegradable | vegetable oil derivatives | -10℃~70℃ | Environmentally sensitive areas |
3. Recent industry hot spots
By analyzing the entire network data in the past 10 days, we found the following hot topics:
| Hot keywords | Discussion popularity | Related events |
|---|---|---|
| Hydraulic oil contamination control | high | A car company recalled a hydraulic system due to contamination |

4. Hydraulic oil selection and usage suggestions
1.Viscosity selection: Select the appropriate viscosity grade (such as ISO VG32/46/68) according to the equipment operating temperature and ambient temperature.
2.Compatibility testing: A sealing material compatibility test is required before replacing oil.
3.pollution control: Regularly detect particulate matter content (NAS level is recommended to be controlled within level 8)
4.Oil change interval: It is recommended to replace it every 2000-4000 hours under normal working conditions, and shortened to 1000 hours under severe working conditions.
5. Future development trends
According to industry white paper data:
| direction | Technical characteristics | Estimated market growth rate (2023-2028) |
|---|---|---|
| Long life hydraulic oil | Antioxidant additive technology | average annual rate of 6.2% |
| Intelligent monitoring of oil products | Nanosensor integration | 9.8% annual average |
| Carbon Neutral Hydraulic Oil | Bio-based + carbon footprint traceability | average annual rate of 12.5% |
Hydraulic oil is the blood of industry, and its technological innovation has always kept pace with the development of the equipment manufacturing industry. As environmental protection requirements increase and smart equipment becomes more popular, high-performance, sustainable hydraulic oil products will become the mainstream choice in the market. Users should pay close attention to industry trends and choose product solutions that meet their own needs.
