Introduction to hydraulic brakes:

Hydraulic brakes, also known as brakes. It is a Machine element that stops or decelerates the moving parts in the machine. Commonly known as brakes or brakes. The brake mainly consists of a brake frame, brake components, and control devices. Some brakes are also equipped with automatic adjustment devices for brake component clearances.

In order to reduce braking torque and structural dimensions, brakes are usually installed on the high-speed shaft of equipment, but large equipment with high safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft near the working part of the equipment. Some brakes have been standardized and serialized, and are manufactured by factories for selection.

Working principle of electric hydraulic brake:

The electric hydraulic brake is composed of electric motors, centrifugal pumps, oil cylinder pistons, and other components. When the mechanism is working, the electric motor 1 is energized, driving the centrifugal pump impeller 5 to rotate under the action of centrifugal force; The high-pressure oil is pumped out and flows into the lower chamber of piston 6, pushing the piston and push rod 2 to rise together. At this time, square shaft 3 rises along the shaft sleeve, and the brake release lever releases the brake.

The impeller of a centrifugal pump adopts radial blades, which can pump high-pressure oil to make the piston move regardless of the direction of current, i.e. the direction of motor rotation. When the mechanism is not working, the electric motor 1 is powered off, the impeller stops rotating, the oil pressure in the lower chamber of the piston decreases, and the tension of the main spring causes the brake to close and brake. At the same time, the piston quickly resets under the gravity of the piston and push rod.
