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.

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:

• Hot topics:#Twin pump combined fuel-saving test#(Tik Tok views 12 million+)
• Technical highlights: Automatically switch single/dual pump mode through pressure sensor, reducing overall fuel consumption by 22%.

3. Disassembly of technical principles

The core of dual pump fusion isTraffic allocation logic:

1. Low voltage and high flow stage: Dual pumps supply oil at the same time to speed up the operation speed
2. High voltage and small flow stage: Only the main pump is working, the secondary pump is unloaded or auxiliary oil supply

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:

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.
