Hydraulic clicker press transmission: It uses hydraulic clicker press oil as the medium, through the power element (oil pump) to convert the mechanical energy of the original idea into the pressure energy of the hydraulic clicker press oil, then control the components through the process, and then use the implementation component (cylinder or oil motor) to pressure Can be converted to mechanical energy, drive the load to achieve a straight or rotary activities, and through the control of the control of the remote control of the components and the flow of adjustment, set the implementation of the elements of force and speed. When the outside world has disturbance to the above system, the output of the implementing component is usually the same as the original setting value, and a certain error occurs.
Hydraulic clicker press control: Like the hydraulic clicker press drive, the system also includes power elements, control elements, and implementation elements, which also report the power via the fluid. The difference between the two is that the hydraulic clicker press control system has a feedback assembly, and the immersion of the feedback assembly is implemented by the feedback of the output of the component (displacement, speed, force, etc.) and the input quantity (which can be changed or constant). Efforts are made to control the system by using short-circuiting points, so that the output of the implementing component changes or becomes constant as the input changes. It is a hydraulic clicker press transmission system that forms a closed-loop circuit. It is also called a hydraulic clicker press servo system or a hydraulic clicker press servo system.
The hydraulic clicker press transmission system uses on-off or logic control elements. Its restraint principle is the purpose of linking the set values to the stability or innocence transformation. It is also called the constant temperature control element.
The top of the hydraulic clicker press control system is a servo control element, which has a feedback structure and is controlled by an electrical assembly. It has a high degree of control accuracy and response speed, and the pressure and flow control are often continuously changed. The output power can be released.
Proportional control is a mode of control between the above two. The proportional control valve is a new type of electro-hydraulic clicker press control element developed on the basis of on-off control elements and servo control elements. Some of the characteristics of the type of components for the on-off control of manual adjustment can not meet the requirements, but also does not require the servo valve to the hydraulic clicker press system as severe pollution control requirements of the occasion.
