Configuration method of long-distance fluid conveying machinery

Abstract

The invention relates to a long-distance fluid conveying machine configuration method, comprising the following steps: connecting a conveying pipeline and a booster pump, selecting a pipeline section on the conveying pipeline; turning on the booster pump to allow fluid to flow into the conveying pipeline, measuring and calculating to obtain the pipeline The pressure difference in the pipe at both ends of the pipe section; the head loss per unit distance of the fluid is calculated according to the pressure difference in the pipe at both ends of the pipe section, the height difference and the length of the pipe section, and then the total head loss of the fluid being transported is calculated; finally, according to the total head loss and The head of the booster pump is calculated to obtain the required number of booster pumps and the spacing of the booster pumps, and the booster pumps are configured accordingly. The present invention selects a pipeline section on the conveying pipeline for simulation, and measures the pressure at both ends of the pipeline section during the simulation process, so as to obtain actual data to calculate the head loss, so that the prediction of the water head loss is closer to the actual than the theoretical value, Better configuration of long-distance fluid transport machinery.

Description

Technical field[0001]The present invention relates to the field of building construction techniques, referred to as a long-distance fluid delivery mechanical configuration method.Background technique[0002]During long-distance fluid transport, there is a need to set a plurality of pumps on the transport conduit, but due to factors such as resistance, fluids will have mechanical energy loss when the pipe is passed, that is, the water head loss. The prior art is usually only theoretical value, and the actual deviation is large, so that the number of boost pumps can be easily caused by setting the pump, or the distance is too far, or the boost pump is set too much. The situation of waste is wasteful.Inventive content[0003]SUMMARY OF THE INVENTION It is an object of the present invention to overcome the deficiencies of the prior art, providing a long-distance fluid delivery mechanical configuration method, which can solve the prior art prediction of the water head loss is usually only th...
