What kind of hydraulic oil does the press use? Hot topics and purchasing guides across the Internet
Recently, the topic of industrial equipment maintenance has become increasingly popular on major platforms, among which "press hydraulic oil selection" has become the focus. This article combines the hot discussions on the Internet in the past 10 days to sort out the core data and practical suggestions for hydraulic oil selection to help users make efficient decisions.
1. Core performance indicators of press hydraulic oil
The performance of hydraulic oil directly affects the working efficiency and life of the press. The following is a comparison of key indicators:
| Indicator type | Standard requirements | FAQ |
|---|---|---|
| Viscosity grade | ISO VG 32-68 (adjusted to ambient temperature) | If the viscosity is too low, it will cause leakage; if it is too high, it will increase energy consumption. |
| Wear resistance | Meets AW or HM standards | Poor quality oil causes pump valve wear |
| Oxidation stability | More than 1000 hours (ASTM D943) | Sludge formation at high temperatures |
| Anti-rust and anti-corrosion | Passed ASTM D665 test | Moisture intrusion causes rust |
2. Popular hydraulic oil brands and user reviews
According to data from e-commerce platforms and industry forums, the following brands have received relatively high attention recently:
| brand | Main model | User feedback | Price range (yuan/liter) |
|---|---|---|---|
| Shell | Tellus S4 VX 46 | Good high temperature stability, suitable for continuous operation | 80-120 |
| Mobil | DTE 10 Excel 68 | Strong wear resistance, but slightly poor at low temperature start-up | 70-110 |
| Great Wall | L-HM 46 | High cost performance, commonly used in small presses | 40-60 |
3. Hydraulic oil replacement cycle and precautions
1.Replacement cycle:Under normal working conditions, it is recommended to replace it every 2000-3000 hours or 12 months. If the environment is dusty or high temperature, it needs to be shortened to 1000-1500 hours.
2.Mixing risks:Mixing different brands/models of hydraulic oil may cause sedimentation, so the system must be thoroughly cleaned before replacement.
3.Environmental trends:Biodegradable hydraulic oils (such as HETG) are becoming increasingly popular in the European and American markets, but mineral oils are still the dominant ones in China.
4. Expert advice
China Hydraulic Industry Association recently pointed out that"Hydraulic oil contamination is the main cause of press failure". Users are advised to:
- Check the oil moisture content regularly (should be <0.1%);
- Use a three-stage filtration system;
- Prefer respirators with desiccant.
Conclusion
The selection of press hydraulic oil requires comprehensive consideration of equipment parameters, working conditions and budget. The data in this article are all from industry reports and user measurements in the past 10 days. It is recommended to save them for later use. If you need specific model recommendations, you can refer to the equipment manual or contact the hydraulic oil supplier to provide a customized solution.
