- Abstract
By analyzing the hydraulic control principle of reciprocating hydraulic booster, the mathematical model of hydraulic booster was established and the preliminary judgment on the working characteristics of hydraulic booster was made according to the mathematical model. At the same time, the dynamic response monitoring of hydraulic booster under different pressure levels was carried out by experiment, and the response characteristics were compared and concluded. It is found that there is a “zigzag” pressure fluctuation in the operation of the reciprocating hydraulic booster, the output pressure is slightly higher than the ideal value and the output error is within 10%.The maximum commutation time increases first and then decreases with the increase of pressure level, and the number of commutations increases with the increase of pressure level. The reciprocating hydraulic booster is inefficient and unsuitable under the condition of less than 30 MPa and high control accuracy, closed-loop control should be introduced to consider its fluctuation characteristics.
