Car brake pump works

In general the speed of acceleration and braking is good or bad car is relatively important performance of two, when it comes to brakes have to mention the brake pump. Brake pump brake system can be divided into the main brake cylinder, brake master cylinder, brake booster pump. Then introduce you to the working principle of the brake pump. Brake Cylinder: Brake Cylinder is an indispensable part of the brake system. Its main function is to brake the brake disc at the top. The brake pad rubs on the brake drum to reduce the speed and stop. Depressing the brake after the master cylinder produces thrust hydraulic pressure to the sub-pump, sub-pump internal piston hydraulic pressure began to move the brake pads. Oil brake is composed of brake master cylinder and brake oil tank. They are attached to the brake pedal, one end of the brake tubing. Brake master cylinder brake oil storage, and a fuel outlet and inlet. When the brakes, the outlet open, close the inlet. Under the pressure of the pump piston, the brake oil pipe is squeezed out of the oil pipe to make brake function for each brake sub-pump. When releasing the brake board. Brake master cylinder in the oil outlet will be closed, the inlet open, the brake oil from the brake sub-pump back to the brake master cylinder, back to its original state. Brake master cylinder: The main part of the hydraulic brake, which has a reservoir of brake fluid savings above, the bottom is equipped with a piston in the cylinder. Pistons in the cylinder by the brake pedal and then by the role of the putter, the cylinder brake hydraulic pressure transmitted to the wheel cylinder, but also the hydraulic brake device, configured in each wheel brake cylinder. Brake booster pump: Brake booster pump is a vacuum chamber with larger diameter. There is a diaphragm (or piston) equipped with a push rod in the middle, the chamber is divided into two parts, one part is connected with the atmosphere, and the other is connected with the atmosphere. One part is connected to the engine intake pipe through a pipe. It is based on the principle of taking in the air when the engine is working, resulting in a vacuum on one side of the booster pump, and a pressure difference relative to the normal air pressure on the other side. This differential pressure is utilized to enhance braking thrust. If there is even a small pressure difference between the two sides of the diaphragm, a large thrust force can be generated due to the large diaphragm area to push the diaphragm toward the less stressed end. The vacuum booster system controls the vacuum entering the booster pump during braking and moves the diaphragm. It also assists the manpower in stepping on and pushing the brake pedal by utilizing the push rod on the diaphragm through the intermodal device. So: the engine flameout, because there is no intake of vacuum, there is no help, the labor required for braking will be great. It should be noted here that there are many novices think that the engine is off there is no brake, this is wrong. Correctly, the engine should be turned off, and the manual stepping needed to brake it would be large because it would not help. Vacuum booster pump works: Vacuum booster pump mainly by the pump body, rotor, slider, pump cover, gears, seals and other components. When the pump is working, the eccentric rotor with four sliders rotates in the counterclockwise direction, the sliders slide on the inner wall of the pump body under the action of centrifugal force of itself, the suction working chamber expands constantly, Tube open the check valve (pump built-in check valve, packing effect on the system) into the suction studio. When the slider to a certain position, inhalation is completed. At this point, the inhaled gas is isolated, the rotor continues to rotate, the isolated gas is gradually compressed - the pressure rise. When the studio goes to communicate with the vent, the gas is vented from the vent. During pump operation, the slider always divides the pump chamber into four working chambers, with one revolution per rotor and four intake and exhaust processes. In the car driving process, the quality of the brake is likely to be related to the issue of life safety, so understanding of the brake pump works better for us to use the brake pump is also helpful.
