Hydraulic power pack include tanks, motor and pump assembly, control valve assembly, start control box, heat exchangers and sensors, pressure gauge, oil and air filters and other accessories; from a functional perspective, the hydraulic power pack with a hydraulic system for back to the oil and oil control function.
Under normal operating conditions, the motor driven hydraulic oil supply to the main system, when the system reaches the rated pressure, pressure sensors control the implementation of one-way valve to close packing functions. Solenoid valve by a hydraulic actuator to open, close, or power to exercise control, with the accumulator in the hydraulic power packs, hydraulic control at the same time, the energy storage device has also been released, the executive body of the packing into the synchronization function, but also to ensure the system security and reliability.
In modern hydraulic system with PLC control hydraulic power pack system, control the internal hydraulic functions and generate signals, and hydraulic proportional valve connection, more accurate speed of the implementing agencies and stretching distance.
