In the current brake system, there are two main types: one is an oil brake and the other is an air brake. However, the pure electric vehicles that have emerged in recent years use electricity as the main power source of the vehicle and cannot use oil brakes, so they can only use air brakes. And because of the characteristics of electric vehicles, only one automotive electronic vacuum pump can be installed on the car. So what is the role of the automotive electronic vacuum pump? What are its characteristics? The following editor will introduce to everyone, let's take a look!

The role of automotive electronic vacuum pump-introduction

The electronic vacuum pump uses piezoelectric materials as the power device (completely abandon the motor drive mode). From control to drive, it is completely electronic, and the electronic integrated system completely controls the gas exchange and transmission, so as to realize the adjustable and precise gas transmission. sex. Due to the integration of the system, the use of motor drive and the use of a miniature vacuum pump for the main part of the air pump have made the entire system truly miniaturized, so the electronic air pump is also called a miniature vacuum pump.

1. The driving mode uses piezoelectric materials as the power device, which overturns the traditional motor drive. 2. It can accurately transport liquids, and is used in liquid quantitative transmission, quantitative control and other fields. 3. The speed of conveying liquid is adjustable. 4. The pump body has its own operation panel, all operations are completed by electronic buttons, fully digital setting, equipped with digital display, intuitive and accurate. 5. Small size and light weight. The advent of electronic vacuum pumps will bring the micro air pump industry into a new era. First, the revolutionary reform of the drive mode has further reduced its size, and secondly, the addition of an electronic control system makes the control of the entire system completely free of manual operation and liquid The precise and adjustable transmission, these two points make the electronic vacuum pump truly miniaturized and intelligent.

Electric vehicles are driven by electric motors, eliminating the traditional engine, so they lose the source of vacuum, that is, they cannot provide vacuum assistance for the automobile brake master cylinder. The electric vehicle vacuum booster pump was created to make up for this shortcoming. It uses the on-board power supply to provide power and pushes the motor on the pump body to move the piston to generate a vacuum. It provides the only and reliable vacuum for the hydraulic brake system of various models of electric vehicles, hybrid vehicles, electric sightseeing cars, electric field vehicles, etc. Source, thereby effectively improving the braking performance of the vehicle.

The role of automotive electronic vacuum pump-working principle

According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas transmission pumps and gas capture pumps. The gas transfer pump is a vacuum pump that can continuously suck and discharge gas to achieve the purpose of pumping. The gas trapping pump is a vacuum pump that allows 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 pumping. A vacuum pump is a device that uses various methods to generate, improve and maintain a vacuum in a closed space. A vacuum pump can be defined as a device or device that uses mechanical, physical, chemical, or physical chemical methods to pump air from the pumped container to obtain a vacuum. With the development of vacuum applications, many types of vacuum pumps have been developed, with pumping speeds ranging from a few tenths of a liter per second to hundreds of thousands and millions of liters per second. According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas transmission pumps and gas capture pumps. As the requirements of vacuum application technology in the field of production and scientific research on its application pressure range become wider and wider, most of them require a vacuum pumping system composed of several vacuum pumps to pump together to meet the requirements of the production and scientific research process. The vacuum application department involves a wide range of working pressures. Therefore, any type of vacuum pump cannot be completely suitable for all working pressure ranges. Different types of vacuum pumps can only be used according to different working pressure ranges and different working requirements. Vacuum pump.
