High-Quality Soft Starter Cabinet 220V-660V

When water pumps in the water industry (such as feed water pumps and sewage pumps) are in operation, the most intractable problem is the "water hammer effect" - under the traditional direct start-up method, water flow instantly impacts the pipeline, which is prone to cause flange leakage and valve damage. The reverse water flow during shutdown is more likely to cause the impeller of the water pump to reverse, seriously affecting the service life of the equipment. This 220V-660V, 22kw-350kw soft start cabinet is specially designed for water supply scenarios, solving the water hammer problem from start-up to shutdown throughout the entire process. During the start-up stage, the equipment gradually increases the pump speed from 0 to the rated value through smooth torque control (supporting S-shaped curves), and the water flow is uniformly pressurized, completely eliminating the start-up water hammer and avoiding excessive instantaneous pressure on the pipeline. The "soft stop" function du…
