What does double pump confluence mean?
In the fields of engineering machinery, hydraulic systems, etc."Dual Pump Combination"It is a professional term that appears frequently. In the past 10 days, the discussion on this technology across the entire network has increased significantly, especially its application cases in energy conservation, emission reduction and efficiency improvement. This article will use structured data to analyze its definition, principles and actual value based on recent hot topics.
1. The core definition of dual pump confluence
Dual pump fusion refers to the combination of the output flows of the two hydraulic pumps to the same actuator (such as oil cylinders and motors) through a hydraulic circuit design. This technology is commonly found in heavy equipment such as excavators and cranes, and can be realized"High and low voltage division"or"Traffic Overlay", thereby adapting to complex working conditions.
| Technical parameters | Single pump system | Dual pump fusion system |
|---|---|---|
| Maximum traffic | 100L/min | 200L/min (theoretical value) |
| Energy consumption comparison | 100% reference value | Can reduce 15%-30% |
| Typical application scenarios | Light equipment | Excavator bucket action, crane lifting |
2. Recent hot related cases
According to the engineering machinery industry information (updated in October 2023), Sany Heavy Industry's latest SY750H excavator is adopted"Intelligent dual pump confluence"Technology has sparked widespread discussion:
| Brand/Model | Technical name | Energy-saving effect | Hot search index |
|---|---|---|---|
| Sany SY750H | Intelligent electrically controlled dual pump confluence | twenty two% | ★★★★☆ |
| XCMG XE380DK | Load-sensitive dual pump confluence | 18% | ★★★☆☆ |
3. Disassembly of technical principles
The core of dual pump fusion isTraffic allocation logic:
Recently, Zhihu hot post "Hydraulic System Oil Saving Black Technology" pointed out that the key breakthrough of this technology lies in"Electronic flow distribution valve"The popularity of the mode switching response time has been shortened from 500ms to 50ms.
4. Industry trend forecast
According to Baidu Index data, the search volume of "dual pump convergence" has increased by 67% year-on-year in the past 10 days, mainly related to the following trends:
| Related Technology | Patent growth (2023) | Investment hotspots |
|---|---|---|
| Electrical control convergence technology | +42% | New energy engineering machinery |
| Digital hydraulic pump | +35% | Automated control system |
In summary, the dual pump confluence technology is“Mechanical Hydraulic”Towards"Smart Electronic Control"The direction evolution has become one of the important technical paths for achieving the "dual carbon" goal in the field of engineering machinery. In the future, with the popularization of 5G remote control, its precise traffic allocation characteristics will be expanded to unmanned operation scenarios.
