Hydraulic transmission control system Hydraulic transmission control is often used in industry, it adopts the hydraulic energy transfer process. Because the hydraulic control flexibility and convenience, hydraulic control has received wide attention in the industry. Hydraulic transmission is based on pressure fluid medium for energy to realize all kinds of machinery and automatic control subjects. The hydraulic transmission of the element to constitute a variety of control loop to use, and then a plurality of circuit transmission system must become the organic combination of complete control function to complete energy transfer, conversion and control. In principle, the hydraulic transmission based on the basic principle is the principle of Pascal, that is, the liquid pressure everywhere is the same, so, in the balance of the system, the piston above relatively small pressure is relatively small, and exert great pressure on the piston is relatively large, which can keep the rest liquid. So through the transfer of the liquid, can be different on different end pressure, so as to achieve the purpose of a transformation. Transfer we have common to the hydraulic jack is to use this principle to force. The basic principle of hydraulic transmission The hydraulic components in the main power components, actuators, control components, auxiliary components etc.. The hydraulic power unit is to generate power for the hydraulic system components, including hydraulic pump. The hydraulic pump depends on the volume change principle to work, so gene
