Hydraulic brake product introduction
Hydraulic brake is a progressive hydraulic brake, which 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 tee block above. This tee block connects the inlet and outlet pipes and the small groove pipes respectively. and the large grooved tube. There is a compression spring in the small grooved tube and the large grooved tube, and a ball is pressed on the spring of the large grooved tube to control the flow of oil to the other side. There is also a continuous connection between the large grooved tube and the inlet and outlet pipes. There is a passage, and a ball is provided on the passage, which can also control the flow direction of the oil. The above structure can achieve the effect of progressive braking, with smooth and sensitive operation, safe and guaranteed, and prevent emergency brake locking. The structure is simple and the appearance is beautiful. It has promotion and application value.
The principle of hydraulic brake 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 structural size, 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. superior. Some brakes have been standardized and serialized, and are 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 block exerts large and uneven pressure on the brake axle, so a pair of brake blocks is usually used to offset the pressure of the brake block 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. When working, the movable iron core rotates around the pin to release the brake magnet and rely on the main spring to tighten the brake when the power is off. This kind of brake has a compact structure, quick tightening and releasing action, but high impact force. The long-stroke brake can generate a large brake release force through the brake lever system, but the braking action is smooth, and is suitable for various types of deceleration equipment
Features of hydraulic brakes
Compact structure and power-off brake shaft Although the directional size is small, the braking torque is large enough.
. Rapid response. The power-off brake uses a spring device to form braking torque. The return time of the spring is the braking response time.
. Long life. The power-off brake adopts new friction materials, which determines the performance of long life.
The brake can work reliably under the following conditions
The relative humidity of the surrounding air is not greater than % (℃)
There is no gas and dust in the surrounding medium that is sufficient to corrode metal and destroy insulation.
. Grade insulation is used around the brake, and 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.
