What is the working principle of the Haval H6 electronic vacuum pump?
2 Answers
Electronic vacuum pump uses piezoelectric materials as the power device (completely abandoning the motor drive mode), realizing full electronic control from control to drive, and the electronic integrated system fully controls gas exchange and transmission, thereby achieving adjustability and precision in gas transmission. Extended information is as follows: 1. Definition: Due to system integration and no longer using motor drive, coupled with the main component, the air pump, adopting a micro vacuum pump, the entire system truly achieves miniaturization, hence the electronic air pump is also called a micro vacuum pump. 2. Significance: The advent of the electronic vacuum pump will bring the micro air pump industry into a brand-new era. Firstly, the revolutionary reform of the drive mode further reduces its size. Secondly, the addition of an electronic control system allows the entire system's control to completely break away from manual operation, achieving precise and adjustable liquid transmission. These two points truly enable the electronic vacuum pump to achieve miniaturization and intelligence.
The Haval H6's electric vacuum pump is quite interesting, and I often study its design. Essentially, it's an independent electric pump used to provide vacuum assistance for the braking system. Here's how it works: when the car starts, if the sensor detects insufficient brake vacuum—such as during low engine load—the controller activates the pump's motor. Inside the pump, there’s a rotating vane or similar mechanism that evacuates air to create negative pressure, making braking lighter and more effortless. This is more reliable than traditional engine-dependent vacuum systems, especially in hybrid models where the engine often shuts off and requires additional assistance. I’ve found it to be highly efficient, reducing fuel consumption while improving response speed. Every time I test-drive, I notice much more responsive braking, particularly during sudden stops in city traffic. However, it’s important to watch out for motor heat dissipation and dust buildup—regular checks can extend its lifespan. Overall, the electric vacuum pump is a microcosm of modern automotive intelligence, making driving safer and more comfortable.
