What is a solenoid brake?
The term solenoid brake concerns the group of brake mechanisms that rely on electric solenoid for their control. The brake mechanism usually consists of two or more brake shoes that are pushed against the rotating element using solenoid -operated bonds. Solenoid brakes are usually used to slow down and stop the rotating equipment, including winch drums, home washing machines and vehicles. There are two basic types of solenoid brake installations - one that develops the brake pressure when the power supply is powered, and the other when the power supply is interrupted. Solenoid brakes can be used by themselves or in combination with mechanical brakes.
Electric solenoid consists of a wire coil wound around a hollow core with a spring charged metal font inside. When electric current passes through the coil, it creates an electromagnetic field that attracts the piston to the core. When the power supply is cut to the coil, the spring pushes the piston out again. This conversion of electrical paintingThe force into linear movement is the basis of the operation of the solenoid brake. Usually the piston acts through a number of bonds that move a set of brake shoes against everything that needs to be slowed or stopped.
these sets of shoes differ significantly in design according to the application. Drum reels, such as those used in underground mining operations, use a set of half -round brake shoes that are pushed against the brake collar on the drum. Other solenoid brakes pull a flat disk lined with brake material against a similar flange to stop rotation. The connection systems also differ in some solenoid brake mechanisms using no physical bonds. Instead, these systems rely on a spring -packed -packed spring attracted against the brake lining on the solenoid face.
The total operation of solenoid brakes falls into two basic categories: power and shutdown. The abstainIt eats to activate solenoid to develop brake forces. Power systems develop the brake force when the power supply is cut and released only when the power supply is applied to the solenoid. Performance systems are often used on vertical mining lifts that transport personal as safety measures against energy failure.
solenoid brakes are often included as safety back to mechanical brake systems. One such application is to block the back brake on the trailers. These systems use the backup light signal to activate the solenoid that releases the brakes of trailers when reversal. Many vehicles also have solenoid brake systems that lock their brakes until the engine is in operation. This prevents stationary, unconditional heavy vehicles to move unintentionally.
