摘要
An auxiliary energy-accumulation and flow-enhancement device for a hydraulic system of a concrete pump is provided. The device includes a connection oil passage 1 having an input end P and an output end B. A check valve 11 is disposed in the oil passage between the input end P and the output end B, and an energy accumulator 10 is connected to the oil passage between the check valve 11 and the input end P Pressure oil enters from the input end P, the energy accumulator accumulates energy, and power oil is output through the check valve 11. An oil passage pressure of the output end B controls an energy accumulation state of the energy accumulator 10. In the course of reversing the oil passage of a distribution valve of a working oil passage device, the auxiliary energy-accumulation and flow-enhancement device releases a corresponding amount of power oil for supplementation. When the oil passage of the distribution valve is not reversed, the auxiliary energy-accumulation and flow-enhancement device also provides the power oil to the working oil passage device. Therefore, the technical solution of the auxiliary energy-accumulation and flow-enhancement device is reliable, and the oil pump operates stably.
