In order to solve the problem of the response time of concrete pump distribution circuit unmatching pumping construcution requirement,which caused by selecting accumulator based on experience, the parameter configuration of the accumulator was quantitatively expressed. The response time of the distribution circuit is divided into switch time of S tube distribution valve and accumulated pressure differential time of the accumulator. In order to meet the requirements of the response time of the pumping construction, based on the existing parameter configuration of the accumulator, with dynamic characteristic equation and gas state equation respectively, the switch time of S tube distribution valve and accumulated pressure differential time of the accumulator is quantitatively calculated, and the parameters of the accumulator is configurated.Compared to the traditional accumulator choice method, namely selecting accumulator according to experience and testing whether the response time of the distribution circuit is reasonable, quantitative calculated parameter configuration of concrete pump accumulator is more accurate, and can fully meet the requirments of pumping construction. This method also provides theoretical basis for design and choice of engineering machinery accumulator. |
