The Aqua Drive System (ADS) is an environmentally friendly system.
In the Aqua Drive System (ADS), an AC servo motor is connected to a bidirectional water pump, allowing high-pressure water to flow in both directions in accordance with the rotation of the AC servo motor. The water that comes out of the bidirectional pump is sent to a water cylinder with built-in sensors, enabling control at any desired position. Since there is no grease or lubricant in the actuator section, it can be safely used for food, cosmetics, pharmaceuticals, and more. 【Features】 ○ No additional control valves or water pressure source devices are required. ○ By combining various actuators, sensors, etc., it can be widely used as an electric hydraulic control system. ○ When combined with servo motors and others, it can control the required water volume based on the motor's rotation speed, resulting in energy savings and low noise.
