The function of automotive electronic vacuum pumps, what is the role of automotive electronic vacuum pumps?

In the current braking system, there are mainly two types: one is hydraulic brakes, and the other is pneumatic brakes. In recent years, pure electric vehicles, which use electricity as the main power source for cars, cannot use hydraulic brakes, so they can only use pneumatic brakes. Additionally, due to certain characteristics of electric vehicles, they can only be equipped with an automotive electronic vacuum pump. So, what is the function of the automotive electronic vacuum pump? What are its characteristics? Let's take a look!

Function of Automotive Electronic Vacuum Pump - Introduction

The electronic vacuum pump uses piezoelectric materials as the power device (completely abandoning the motor drive mode), achieving full electronic control from control to drive, and completely controlling the exchange and transmission of gas through an electronic integrated system, thus achieving the adjustability and precision of gas transmission. Due to system integration and the non-use of motor drive, combined with the main component of the gas pump using a micro vacuum pump, the entire system has truly achieved miniaturization, so the electronic gas pump is also called a micro vacuum pump.

Function of Automotive Electronic Vacuum Pump - Characteristics

1. The drive mode uses piezoelectric materials as the power device, subverting the traditional motor drive. 2. It can accurately deliver liquids, used in fields such as liquid quantitative transmission and quantitative control. 3. The speed of liquid delivery is adjustable. 4. The pump body comes with an operation panel, all operations are completed through electronic buttons, fully digital settings, equipped with a digital display, intuitive and precise. 5. Small size and light weight. The emergence of the electronic vacuum pump will bring the micro gas pump industry into a brand new era. First, 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 free from manual operation, achieving precise and adjustable liquid transmission. These two points enable the electronic vacuum pump to truly achieve miniaturization and intelligence.

Electric vehicles use motors for driving, eliminating the traditional engine, thus losing the vacuum source, which means they cannot provide vacuum assistance to the car's brake master cylinder. The electric vehicle vacuum assist pump was created to compensate for this deficiency. It uses the onboard power supply to provide power, driving the motor on the pump body to create piston movement, thereby generating vacuum, providing the only reliable vacuum source for hydraulic brake systems of various models such as electric vehicles, hybrid vehicles, electric sightseeing vehicles, and electric venue vehicles, effectively improving the overall braking performance of the vehicle.

Function of Automotive Electronic Vacuum Pump - Working Principle

According to the working principle of vacuum pumps, vacuum pumps can be basically divided into two types: gas transfer pumps and gas capture pumps. A gas transfer pump is a vacuum pump that continuously sucks in and expels gas to achieve the purpose of gas extraction. A gas capture pump is a vacuum pump that causes gas molecules to be adsorbed or condensed on the inner surface of the pump, thereby reducing the number of gas molecules in the container to achieve the purpose of gas extraction. A vacuum pump is a device that generates, improves, and maintains vacuum in a closed space using various methods. A vacuum pump can be defined as a device or equipment that obtains vacuum by extracting gas from the container using mechanical, physical, chemical, or physicochemical methods. With the development of vacuum applications, the types of vacuum pumps have evolved significantly, with extraction rates ranging from a few liters per second to hundreds of thousands or millions of liters per second. According to the working principle of vacuum pumps, they can be basically divided into two types: gas transfer pumps and gas capture pumps. As the requirements for the pressure range of vacuum applications in production and scientific research continue to widen, most systems require several types of vacuum pumps to work together to meet the requirements of production and scientific research processes. Due to the wide range of working pressures involved in vacuum applications, no single type of vacuum pump can be completely suitable for all working pressure ranges; different types of vacuum pumps must be used according to different working pressure ranges and requirements.
