| How to realize braking of brake shears? Sluice shear is a kind of shearing machine. It adopts all-steel welding frame, right-angle guide rail with four corners and eight sides, high precision, good rigidity, and hydraulic preloading. The operation is simple. How does the brake shear brake? Now let's look at the details. 1. Electromagnetic braking is to lock the axle of brake shears by mechanical devices. Electromagnetic braking usually starts after SV and OFF. Otherwise, it may cause amplifier overload. Dynamic brake usually starts after SV, OFF or main circuit is cut off. Otherwise, it may cause dynamic brake resistance overheating. 2. Dynamic braking is composed of dynamic braking resistance, which shortens the mechanical feed distance of brake shears by energy-consuming braking in case of failure, emergency stop and power failure. Dynamic brake does not need power supply and needs external relay control when it works. How to Realize Braking of Brake Shears 3. Regenerative braking is that the braking energy of the brake shears is fed back to the DC bus through the inverted circuit when they are working at deceleration or dwelling. It is absorbed by the resistance-capacitance circuit. Regenerative braking must work only when the server is working normally. Otherwise, the brake shears cannot be braked under the conditions of failure, emergency stop and power cut-off, and the work is carried out automatically by the system. Above is how to realize the braking of the brake shears. Friendship reminder: in the operation of the gate shears must be in accordance with the operating rules, oh, and daily maintenance must be done, so as to extend the service life oh. |
