Pipeline flowing stabilization control method

Abstract

The invention discloses a pipeline flowing stabilization control method which comprises the following steps: establishing a hydraulic system; setting a water pump and a pressure stabilizing tank in the hydraulic system; starting the water pump, and feeding water into the pressure stabilizing tank; charging a certain amount of gas into the pressure stabilizing tank, at this moment the pressure stabilizing tank is filled with a certain amount of gas and water; releasing a water control valve, feeding the water into a flowing stabilization control section from the pressure stabilizing tank, monitoring the water pressure through a pressure tester in real time, wherein the pressure tester is connected with a control unit so as to control the water pump, and the pressure tester is automatically started or is used for adjusting or stopping the water pump; performing compensating by the water pressure fluctuation through an energy accumulator to a certain extent; feeding the water flow in the pipeline into a commutator through the flowing stabilization control section and into a calibration system through the commutator so as to reach a calibrated acquisition quantity, and turning the commutator to a bypass so as to feed the water back to the water pump; and feeding the water back to the water pump after the calibration system accomplishes the test. According to the method, stable flowing is obtained by employing a combined mode of an electronic control method and an energy accumulator, the structural design and the control are simple, the occupied space is small, and the mounting and the debugging are convenient.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to a method for controlling the stability of pipeline flow in a water conservancy system. Background technique [0002] The hydraulic test system is a comprehensive platform for the study of fluid flow and related applications. The calibration and verification of flow measurement devices is an important application field of hydraulic systems. Since the flow measurement is greatly affected by the external environment, including: temperature, viscosity, and flow field distribution in the flow measurement pipeline, the flow measurement device needs to pass the actual flow calibration of the hydraulic calibration system. During the calibration process, a stable pipeline flow is a prerequisite for the calibration of flow measurement devices. [0003] Currently, the steady pipeline flow is mainly provided by the water tower, and the water is pumped from the storage tank to the...
