What hydraulic oil is best for excavators? Analysis of hot topics across the Internet and purchasing guide
Recently, the topic of construction machinery maintenance has become increasingly popular on major platforms, especially "excavator hydraulic oil selection" which has become the focus of industry discussion in the past 10 days. This article combines hotspot data from the entire network to provide you with a structured analysis of the key points for purchasing hydraulic oil, helping you extend the life of your equipment and improve work efficiency.
1. Comparison of popular hydraulic oil types across the entire network (top 5 searches in the past 10 days)
| Hydraulic oil type | Applicable temperature range | Viscosity grade | Average price (yuan/liter) |
|---|---|---|---|
| HM anti-wear hydraulic oil | -15℃~50℃ | ISO VG 46 | 45-60 |
| HV low temperature hydraulic oil | -30℃~80℃ | ISO VG 32 | 55-75 |
| HL ordinary hydraulic oil | 0℃~40℃ | ISO VG 68 | 30-45 |
| Biodegradable hydraulic oil | -10℃~60℃ | ISO VG 46 | 80-120 |
| High pressure synthetic hydraulic oil | -40℃~120℃ | ISO VG 68 | 90-150 |
2. Analysis of hot spot purchasing criteria
1.Viscosity selection: According to data from the Douyin #construction machinery topic, 70% of hydraulic system failures are caused by improper viscosity. ISO VG 68 is recommended in summer, and ISO VG 32 or 46 is recommended in winter.
2.Anti-wear properties: A hot discussion on Weibo pointed out that HM grade hydraulic oil can reduce the wear of key components by up to 40%, and is especially suitable for large excavators above 20 tons.
3.Environmental requirements: Baidu Index shows that the search volume of "biodegradable hydraulic oil" increased by 120% week-on-week, and is mainly used in environmentally sensitive scenes such as wetlands, agriculture and forestry.
3. Performance comparison of popular brands (based on e-commerce platform sales data)
| brand | Antioxidant | Anti-foaming property | Oil change interval (hours) | market share |
|---|---|---|---|---|
| Shell | excellent | good | 2000 | 28% |
| Mobil | excellent | excellent | 2500 | 25% |
| Great Wall | good | good | 1500 | 18% |
| Kunlun | good | middle | 1200 | 15% |
4. Operation hotspot reminders
1.Mixed warning: A Zhihu hot post emphasized that mixing different brands of hydraulic oil may cause precipitation, and it is recommended to clean the system thoroughly before replacing it.
2.pollution control: Kuaishou short video data shows that using special refueling equipment can reduce particle pollution by 80%.
3.Detection frequency: Industry influencers recommend checking the moisture content every 250 hours. If it exceeds the standard by 0.1%, it needs to be replaced.
5. Seasonal maintenance hot trends
1.Winter warm-up: A headline article pointed out that in a -10°C environment, it is necessary to idle for 15 minutes before operating.
2.Heat dissipation in summer
6. Summary of Expert Suggestions
1.Economical choice: Small and medium-sized excavators (<15 tons) can choose HM46 hydraulic oil, which can save about 3,000 yuan in annual costs.
2.High-end configuration recommendations: Synthetic HV hydraulic oil is recommended for operations in plateau/extremely cold areas. Although the unit price is high, it can extend the oil change interval by 50%.
3.future trends: According to analysis by Bilibili Technology UP, smart hydraulic oil (with sensors) is expected to occupy 15% of the market share within 2 years.
Choosing the right hydraulic oil can not only improve the working efficiency of the excavator, but also significantly reduce maintenance costs. It is recommended that users regularly monitor the oil status to achieve scientific maintenance based on comprehensive considerations of equipment model, working environment and budget.
