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. Purchasing and maintenance costs are relatively high, and the purchase generally 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. The structure is complex and difficult to maintain. Maintenance personnel need to master multiple technologies to ensure the normal operation of the machine

The invention provides a method for brake fluid positive-pressure filling, which comprises the following steps: firstly, inputting brake fluid to a stabilization tank from an oil tank; exhausting bubbles and pressurizing the brake fluid by a pressure pump; filling the brake fluid without the bubbles into a brake system of an automobile; turning on an exhaust valve at the tail end of the brake system of the automobile; stopping filling the brake fluid when drained brake fluid does not contain the bubbles and turning off the exhaust valve at the tail end of the brake system at the same time. The method has simple procedure and convenient operation, does not have steep requirements for the technical level of operators and reduces the cost. A machine for brake fluid positive-pressure filling has good brake fluid filling effect, simple structure and operation, easy control and low manufacture and maintenance cost.
Description
technical field [0001] The invention relates to a brake fluid filling machine, in particular to a brake fluid positive pressure filling machine and method for vehicles. 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 th...
