Problems solved by technology
[0004] 1. The vacuum requirements of the brake pipeline of the car are relatively high, and a slight leakage will lead to filling failure;
[0005] 2. The cost of procurement and maintenance is relatively high. Generally, the procurement costs hundreds of thousands or millions, and the parts on the machine are also very expensive, and a large sum of money is invested in maintenance every year;
[0006] 3. Complex structure and difficult maintenance

Embodiment Construction
[0024] Such as figure 1 As shown, a device for eliminating air bubbles in the brake fluid of the present invention includes a first pipeline 1, a second pipeline 2, a third pipeline 3 and a fourth pipeline 4, and also includes a stabilizing device 50, the stabilizing The device 50 is a stabilizing tank 51. The stabilizing tank 51 utilizes the volume change in the tank to change the force of the liquid and the air, so that the liquid and the air are elastically deformed. The stabilizing device 50 is connected in series with the first pipeline 1 and the second pipeline 2, the cross-sectional area of the stabilizing tank 51 is greater than the cross-sectional area of the first pipeline 1 described at the connection, and the cross-sectional area of the stabilizing tank The area is greater than the cross-sectional area of the second pipeline 2 at the connection. The first pipeline 1 includes an oil barrel 78, a second electric oil pump 77, a liquid replenishment oil tank 7...

The invention discloses a device for eliminating air bubbles in brake fluid, which comprises a first pipeline (1) and a second pipeline (2), the device further comprises a stabilizing device (50), the stabilizing device (50) is connected with the first pipeline (1) and the second pipeline (2) in series, and the stabilizing device (50) is a stabilizing tank (51). The device can naturally separate the most of air in the brake fluid by standing and collect and automatically exhaust the air bubbles by the stabilizing device, thereby separating the air in the brake fluid, ensuring the purity of the brake fluid for adding and allowing the brake performances of a vehicle to achieve good effects; the operation procedure is simple and convenient; furthermore, the device has no excessive high requirements on the technical levels of operators, thereby reducing the cost.
Description
【Technical field】 [0001] The invention relates to a liquid conveying device, in particular to a device for eliminating air bubbles in brake fluid. 【Background technique】 [0002] Earlier brake fluid filling was manually filled. The specific method is: one person continuously steps on the brake pedal of the car back and forth in the cab, uses the brake pump of the car to pressurize the brake fluid, and sends the brake fluid to the brake pipeline, while the other person Open the exhaust valve of the brake pipeline at the bottom of the car, and use the flow of brake fluid to discharge the air in the brake pipeline to achieve the purpose of removing the air from the brake pipeline. The employees in the cab still need to continuously replenish the brake fluid in the brake fluid oiler. After the operation is completed, they also need to adjust the oil level line in the brake fluid oiler so that the brake fluid in the oiler can be stored. The quantity meets the technical requirem...
