As water ring vacuum pumps become increasingly common, their quality has also improved significantly. Due to their distinctive advantages, they are now widely used. To help you make better use of them, let us take a look at the various braking methods employed during the operation of water ring vacuum pumps.

Water-ring vacuum pumps are widely used and serve a broad range of applications. In terms of the equipment as a whole, it is a device capable of pumping both water and air through pressure-driven operation. When decelerating or stopping, a water-ring vacuum pump feeds the energy generated by braking back to the DC bus via an inverter circuit, where it is absorbed by a resistive circuit. Regenerative braking is effective whilst the servo is operating normally; however, in the event of a fault, emergency stop or power failure, the motor cannot be braked, and the system operates automatically. Electromagnetic braking: This locks the shaft of the SK water-ring vacuum pump via a mechanical device. Electromagnetic braking is typically activated after SV or OFF. Otherwise, the amplifier may become overloaded. Dynamic braking is usually activated after SV, OFF or a main circuit power failure. Otherwise, the dynamic braking resistor may overheat. Comprising a dynamic braking resistor, it uses energy dissipation to brake and reduce the mechanical travel distance of the water ring vacuum pump during faults, emergency stops or power failures. The dynamic braking system operates without a power supply and requires control via an external relay. Applying appropriate braking methods during certain vacuum pump operations has a positive impact on pump performance, effectively improving efficiency and enhancing its functionality.

The above outlines the braking methods used during the operation of water ring vacuum pumps.
