What brand of hydraulic oil is good? Popular brands and purchasing guides across the Internet
With the wide application of industrial machinery and engineering equipment, hydraulic oil is a key lubricating medium, and its quality and brand selection have attracted much attention. This article combines hot topics and user discussions on the Internet in the past 10 days to sort out hydraulic oil brand rankings, performance comparisons and purchasing suggestions to help you easily find the right hydraulic oil.
1. Hydraulic oil brand popularity rankings in 2023
| Ranking | brand name | Popular index | Core advantages |
|---|---|---|---|
| 1 | Shell | ★★★★★ | World-renowned and highly resistant to wear and tear |
| 2 | Mobil | ★★★★☆ | Good high temperature stability |
| 3 | Great Wall Lubricant | ★★★★☆ | High cost performance, domestically produced leader |
| 4 | Castrol | ★★★☆☆ | Environmentally friendly formula, excellent cold start |
| 5 | Kunlun lubricating oil | ★★★☆☆ | Military quality, many viscosity options |
2. Comparative analysis of key performance of hydraulic oil
| Performance indicators | Shell | Mobil | Great Wall | Applicable scenarios |
|---|---|---|---|---|
| Viscosity index | ≥95 | ≥98 | ≥92 | Choose high index for high-speed equipment |
| Flash point(℃) | 220-240 | 230-250 | 210-230 | High temperature environment requires ≥220℃ |
| Pour point(℃) | -30~-36 | -33~-40 | -25~-30 | Choose a low pour point in cold areas |
3. Three golden rules for purchasing hydraulic oil
1.See equipment requirements: Different equipment such as excavators and injection molding machines have clear requirements for ISO viscosity grades (such as 32/46/68), and the instructions must be strictly followed.
2.Look at the working environment: In northern winter, it is recommended to use low-temperature hydraulic oil with a pour point lower than -30°C; for mining machinery, anti-wear products such as Shell Rimula series are recommended.
3.See certification standards: High-quality hydraulic oil should pass international certifications such as DENISON HF-0 and ISO 11158. Great Wall L-HM series has obtained mainstream certification.
4. Selection of real user reviews
| brand | Positive points | Bad review points | Typical user |
|---|---|---|---|
| Mobil DTE 20 | Good filtration performance and less sludge | Price is on the high side | Injection molding machine manufacturers |
| Great Wall L-HL 32 | The king of cost-effective domestic alternatives | Slightly less durable at high temperatures | Small and medium-sized machinery factory |
| Shell Tellus S4 | Significant energy saving effect | Channel control needs to be strengthened | port crane |
5. Suggestions from industry experts
1.Oil change interval: Ordinary hydraulic oil is recommended to be replaced every 2000-3000 hours, and the long-lasting type can last up to 5000 hours (need to cooperate with oil testing).
2.Risk of mixing: Mixing different brands of hydraulic oil may cause precipitation. The system must be thoroughly cleaned when changing brands.
3.Distinguish between true and false: Genuine hydraulic oil packaging has an anti-counterfeiting code, and the bubbles dissipate quickly after shaking (the fake oil bubbles are long-lasting).
Summarize: When choosing a hydraulic oil brand, international brands such as Shell and Mobil have excellent performance but high prices, while domestic products such as Great Wall and Kunlun have outstanding cost performance. It is recommended to give priority to products that have passed mainstream certification based on comprehensive consideration of equipment operating conditions, budget and supplier services. Only by regularly testing the oil status can the efficiency of the hydraulic system be maximized.
