What fuel is added to hydraulic forklifts? Comprehensive analysis of hydraulic oil selection and maintenance guide
As the core equipment of the logistics and warehousing industry, hydraulic forklifts are closely related to the maintenance of hydraulic systems. Choosing the right hydraulic oil can not only extend the life of the equipment, but also improve work efficiency. This article will combine popular topics across the Internet in the past 10 days to answer the oil use questions of hydraulic forklifts in detail and provide structured data references.
1. Common hydraulic oil types for hydraulic forklifts
| Oil type | ISO viscosity grade | Applicable temperature range | Core features |
|---|---|---|---|
| Mineral oil type hydraulic oil | HL32/HL46 | -10℃~60℃ | Affordable, basic rust-proof |
| Anti-wear hydraulic oil | HM32/HM46 | -20℃~80℃ | Zinc additives to protect precision components |
| Low temperature hydraulic oil | HV32/HV46 | -30℃~90℃ | High viscosity index, suitable for cold areas |
| Biodegradable hydraulic oil | HEES | -15℃~70℃ | Environmentally friendly formula, special for food-grade places |
2. Key indicators for oil selection (hot search data in the past 10 days)
According to the discussions of Baidu Index and industry forums, the three most concerned oil selection indicators are:
| Ranking | Focus on indicators | Hot search index | illustrate |
|---|---|---|---|
| 1 | Viscosity grade | 8,542 | No. 46 oil accounts for 67% |
| 2 | Anti-wear properties | 6,217 | The discussion volume of zinc-containing formula increased by 35% weekly |
| 3 | Temperature adaptability | 5,893 | The number of user consultations in the north has increased significantly |
3. Latest industry trends (hot spots in the past 10 days)
1.Impact of new environmental regulations: Warehouses in many places have begun to require the use of biodegradable hydraulic oil, and the search volume of HEES products has increased by 120% month-on-month.
2.Pre-warning of counterfeit oil products: A brand of hydraulic oil has appeared counterfeit products, and the State Administration for Market Regulation has intervened in the investigation
3.Technical breakthrough: A manufacturer launched a new nano additive hydraulic oil, claiming that it can extend the oil change cycle by 50%
4. Oil change cycle suggestions
| Working conditions | Suggested cycle | Test indicators |
|---|---|---|
| Regular warehousing operations | 2000 hours/year | Moisture ≤0.1%, viscosity change ±10% |
| High-intensity work | 1000-1500 hours | Acid value ≤1.5mgKOH/g |
| Extreme environment | Quarterly testing | Particle pollution degree NAS ≤8 |
5. Operation precautions
1.Mixed oil products are strictly prohibited: Mixing of different brands of hydraulic oil may lead to precipitation
2.Check oil level regularly: Insufficient oil volume will cause damage to the pump suction
3.Oil temperature monitoring: Ideal working temperature is 40-60℃, if it exceeds 80℃, please shut down immediately for inspection
4.Filter replacement: It is recommended to replace the oil return filter every 500 hours
6. Frequently Asked Questions (High-frequency questions in the past 10 days)
Q1: Can winter hydraulic oil be used in summer?
A: Not recommended. Oils with slightly higher viscosity should be used in summer (such as ISO VG46) and low viscosity oils (such as ISO VG32) in winter.
Q2: What should I do if the hydraulic oil becomes white?
A: It means that the oil is emulsified, and it needs to be replaced immediately and checked for the reason for the water entering, which may be a malfunction of the respirator or a poor seal.
Q3: Can engine oil be used instead of hydraulic oil?
A: Absolutely prohibited. Engine oil does not contain the necessary anti-foaming and anti-rust additives for hydraulic systems.
7. Comparison of mainstream brands in 2023
| brand | Celebrity Products | Price range | Market share |
|---|---|---|---|
| Shell | Tellus S Series | 120-180 yuan/liter | 28% |
| Mobil | DTE 10 Series | 100-160 yuan/liter | 25% |
| Great Wall | L-HM series | 80-130 yuan/liter | 18% |
Conclusion: Correct selection and maintenance of hydraulic oil is the key to ensuring the stable operation of the forklift. It is recommended that users choose regular channel products that meet ISO standards based on the requirements of the equipment instructions and the specific working conditions and ambient temperature. Regular oil testing can detect potential problems in advance and avoid major losses.
