A motor-driven compressor is formed with a compressor device for compressing refrigerant and a motor for driving the compressor device. It includes a drive circuit, which controls the driving of the motor. The drive circuit is provided on an exterior surface wall of a refrigerant suction passages and it is buried within an insulating resin material. In motor-driven compressors, the drive circuit is cooled without using additional cooling equipment.
Motor Driven Etching Printing Presses provides maximum performance. Its motorized drive systems are wired to meet international requirements. It provides safety guard system. It is mounted on each side of the pressure drum and attached directly to the bearing support units. They move up and down with the pressure drum remaining a constant distance. The guard is automatically shut down the motor drive and prevents injury. The drive system is reactivated by simply pressing the restart button. Its controller has high speed return switch returns the bed to the inking position at maximum speed. All control switches are mounted conveniently on the operator's side of the press. It increases braking performance. It allows the operator complete control of the bed travel length.
Motor driven metering pumps are designed for high output applications. The drive incorporates a variable eccentric design, which ensures smooth output and reduces system shock. The mechanically actuated diaphragm reduces the possibility of hydraulic oil contamination of process liquid, which makes this an ideal pump for water treatment applications.
