Working principle of booster pump.
The working principle of booster pump mainly relates to the working mechanism of automobile direction booster pump and brake vacuum booster pump. Direction booster pump through the motor according to the rotation torque and steering direction to issue action instructions, output the corresponding size of the rotation torque, so as to produce the power steering effect. The brake vacuum booster pump uses the principle of inhaling air when the engine is working to form a vacuum state on one side of the booster and form a pressure difference with the normal air pressure on the other side, thereby enhancing the brake thrust.
The working principle of the directional booster pump involves the torque sensor to sense the torque of the steering disk and the direction to be rotated, and sends signals to the electronic control unit (ECU) through the data bus. The ECU commands the motor to output the corresponding rotational torque according to the signal to realize the power steering. This way can effectively reduce the driver's control burden, improve control flexibility and safety, and maintain accurate feel at high speeds.
The working principle of the brake vacuum booster pump is to use the principle of inhaling air when the engine is working, forming a vacuum state on one side of the booster, forming a pressure difference with the normal air pressure on the other side, thus enhancing the brake thrust. The diaphragm moves under the action of pressure difference, drives the push rod of the brake master pump, and realizes the magnifying effect of the leg strength. This design is not only widely used in traditional vehicles, but also in new energy vehicles and hybrid vehicles, providing important auxiliary functions for the brake system.
To sum up, the working principle of booster pumps includes two main types of directional booster pumps and brake vacuum booster pumps, which provide steering and braking assistance for the car through different mechanisms, improving the safety and comfort of driving.
booster pump U-type tubing has the advantages of mature and stable technology, long service time, high reliability and low production cost, so it has been widely used in automobiles. U-type oil pipe of booster pump belongs to a part of mechanical hydraulic power steering system, which is composed of hydraulic pump, oil pipe, pressure flow control valve body, V-type transmission belt, oil storage tank and other components. This system regardless of whether the car needs steering power, the system is always in a working situation, and the energy consumption is relatively huge. However, because the mechanical hydraulic steering power system is the most common type of power assist, and the production cost is relatively low, this technology has been widely used in the automobile .
However, the disadvantage of booster pump U-pipe is that the energy consumption is large. In order to maintain the pressure within the system, the hydraulic power steering system is always in operation even if the car does not need steering power, which leads to a huge consumption of energy. Specifically, the oil in the pipeline of the atmospheric hydraulic power system always maintains a high pressure situation, which consumes huge energy; The steering pump of the normal flow hydraulic steering power booster system is always working, but when the hydraulic power booster system is not working, the oil pump is in idle state, and the relative energy consumption is less .
In summary, although U-type oil pipe has advantages in mature technology and low cost, its shortcomings of high energy consumption can not be ignored.
