Hydraulic brake product introduction
Hydraulic brake: It is a progressive hydraulic brake that mainly includes a hydraulic brake, a brake disc that connects the actuation, and a brake wire that supplies oil to the brake. The brake is an irregular block with two circular grooves of different sizes inside. Each circular groove is connected to a three-way block above. This three-way block is connected to the inlet and outlet pipes, the small groove pipe and the large groove pipe respectively. There is a compression spring in both the small groove tube and the large groove tube, and a ball is pressed against the spring of the large groove tube to control the flow of oil; in addition, a passage is connected between the large groove tube and the inlet and outlet pipes and is on the passage. A ball can also control the flow of oil. The above-mentioned structure can achieve the effect of progressive braking. The operation is smooth, sensitive, safe and guaranteed to prevent emergency brake lock-up. The structure is simple and beautiful, and has the value of promotion and application.
Principle of hydraulic brake: It is a mechanical part that stops or slows down the moving parts in the machine. Commonly known as brakes and brakes. The brake is mainly composed of frame, brake parts and control device. Some brakes are also equipped with automatic adjustment devices for brake clearance. In order to reduce the braking torque and structure, the brake is usually installed on the high-speed shaft of the equipment. However, large equipment with higher safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft close to the working part of the equipment. Some brakes have been standardized and serialized and manufactured by professional factories for selection.
A brake that relies on the brake block to press against the brake wheel to achieve braking. A single brake pad exerts large and uneven pressure on the brake axle, so a pair of brake pads is usually used to offset the pressure of the brake pad on the brake axle. It is divided into short-stroke block brake and long-stroke block brake according to the length of the operating device stroke. The magnet of the short-stroke block brake is directly mounted on the brake arm. During operation, the movable iron core rotates around the pin to release the brake; when the magnet is powered off, the main spring tightens the brake. This kind of brake has a compact structure and fast braking and releasing action but strong impact force. The long-stroke brake can generate large brake release force through the brake lever system, but the braking action is smooth and suitable for various types of deceleration equipment
Features of hydraulic brakes:
Compact structure, axial direction of power-off brake Although small in size, the braking torque is sufficient.
. Rapid response. The power-off brake uses a spring device to form a braking torque. The spring return time is the braking response time.
. Long life. The power-off brake adopts new friction materials to determine the long life performance.
The brake can work reliably under the following conditions:
, the relative humidity of the surrounding air is not greater than % (&;℃)
, and there is no gas and dust in the surrounding medium that is enough to corrode metal and destroy insulation. .
. Class B insulation is used around the brake. The voltage fluctuation does not exceed +% and -% of the rated voltage. Its working mode is a continuous working system.
During installation, the matching accuracy of the drive shaft and the brake should be ensured.
The brake disc of the brake must be used without oil stains.
