文章摘要: Pumping flow loss will cause spraying without concrete at the main pump reversing moment. It leads to the uneven gunite concrete, the dropping of supporting strength, the delay of construction period. In allusion to the instantly pumping flow loss at the main pump reversing moment, this text analysis the cause of pumping flow loss by experiment, puts forward the solution of using best current peak to track the pumping flow loss and establishes the mathematical model. The paper verifies the correctness of the model through a number of experiments. The import of this model in the engineering practice eliminates the intermittent phenomenon at reversing moments and guarantees the construction quality. The conclusions have guiding significance for the improvement of electro-hydraulic control system related to construction machinery.
