What are the crane triple pumps?: Function analysis and hot topics
Recently, crane triple pumps have been widely discussed as a hot topic in the field of construction machinery. Combining the hot content of the entire network for the past 10 days, this article will deeply analyze the functional division of crane triple pumps and present its core role through structured data.
1. Three core functions of crane triple pump
| Pump type | Main functions | Associated System | Typical application scenarios |
|---|---|---|---|
| Main pump | Provides lifting power for booms | Lifting system | Heavy lifting operation |
| Steering pump | Control vehicle steering hydraulics | Steering system | Mobile crane walking |
| Auxiliary pump | Drive legs and other accessories | Auxiliary system | Stable positioning on site |
2. Relevant analysis of recent hot topics
According to the network-wide data monitoring, the high-frequency discussion points related to crane triple pumps in the past 10 days include:
| Hot Topics | Discussion hot topic | Technical Relevance Points |
|---|---|---|
| Renovation of hydraulic system of new energy crane | ★★★★☆ | Energy efficiency optimization of triple pump |
| 5G remote control crane accident | ★★★☆☆ | Hydraulic feedback delay problem |
| Extreme weather construction safety | ★★★★★ | Low temperature protection for pump body |
3. In-depth analysis of technical details
By disassembling recent popular technical discussion posts, we found that the following technical features of crane triple pumps are the most popular:
1.Pressure distribution mechanism: The main pump usually adopts a variable plunger design, with a working pressure up to 35MPa, and the steering pump is mostly a gear pump, with a pressure range of between 10-16MPa.
2.Flow coordination control: Modern electronic control systems realize three-pump linkage through CAN bus, which is also the technical basis for the recent "smart hydraulic" topic.
3.Trends for troubleshooting: Big data shows that steering pump failure accounts for 42%, mainly related to hydraulic oil pollution, which has been frequently cited in recent maintenance discussions.
4. Latest news for industry applications
| Application areas | Technological innovation | Representative of the enterprise |
|---|---|---|
| Wind power installation | Exceeded working condition pump set configuration | Sany Heavy Industry |
| Bridge construction | Dual main pump redundant design | XCMG Machinery |
| Rescue and rescue | Quick switch valve set | Zoomlion |
5. Hot maintenance suggestions
Based on the recent discussions in multiple technical forums, we have compiled three key points for maintenance of triple pumps:
1.Oil selection: It is recommended to use ISO VG46 anti-wear hydraulic oil, and the replacement cycle does not exceed 2000 hours.
2.Filter element replacement: The main pump oil return filter element should be inspected every 500 hours, which is a common lesson from many recent failures.
3.Winter protection: In the subject of cold wave weather, experts recommend installing oil temperature preheating devices to avoid cold start damage.
Through the above structured data analysis, it can be seen that the technological development of crane triple pumps is deeply integrated with the current hot topics in the field of engineering machinery. Whether it is new energy transformation or intelligent upgrade, its core is precise control and coordinated optimization of the three pump groups.
