For hydraulic drive control method of flexibility and convenience, hydraulic control is being widely in industry. Hydraulic transmission is the study of pressure in a fluid medium for energy, to achieve a variety of machinery and automatic control subjects. Hydraulic drive needed to use this component to form a variety of control circuit, and completed by several loop organic combination for a certain control function of the transmission system to accomplish the transmission of energy, conversion and control. In principle, the hydraulic transmission is based on the basic principle is the PASCAL's principle, that is, in all parts of the liquid pressure is consistent, in this way, the balance of the system, the smaller piston top pressure is small, and the big pressure on the piston is bigger, it can keep the liquid stationary. Through liqui...
