specific Embodiment approach 1

[0042] Specific Embodiment 1: A method for testing and evaluating the energy-saving effect of pipeline exhaust in this embodiment is carried out in the following steps:

[0043] 1. Preparatory work before the test evaluation: select a section of water pipeline with a conveying distance of 4km~6km and large fluctuations, install a power meter at the water pump, and install a flowmeter between the water pipeline and the water pump, and then Select 10 pressure measuring points equidistantly on this section of the water pipeline, and install an exhaust valve and an air inlet pipe corresponding to each pressure measuring point, and these 10 air inlet pipes are connected to an air pump;

[0044] 2. The simulated pipeline is tested under the condition of initial water flow:

[0045] 1. Measurement of parameters under the condition of closing the exhaust valve: firstly close the air pump and exhaust valve, start the water pump for 5 minutes, and start measuring the power value P of th...

Abstract

The invention discloses a testing and evaluating method of pipeline exhausting energy-saving effect. The method solves the problems in an existing testing and evaluating method of the pipeline exhausting energy-saving effect that whether the function of energy consumption reduction is achieved by pipeline exhausting or not is only verified qualitatively and the energy saving effect of an exhaust valve can not be estimated quantificationally. The method comprises the following steps: step 1, preparation work before the testing and evaluating; step 2, testing is conducted on a simulated pipeline under the condition of first drainage; step 3, testing is conducted on the simulated pipeline under the condition of drainage for a long time: step 4, unit consumption is calculated through obtained parameters; and step 5, the effect of exhausting energy saving is evaluated. The testing and evaluating method of the pipeline exhausting energy-saving effect is suitable for the field of water conveyance project.

Description

technical field [0001] The invention relates to a method for testing and evaluating the energy-saving effect of pipeline exhaust. Background technique [0002] Due to the long distance and complicated lines of urban long-distance water pipelines, gas collection or even flow failure may occur in some pipe sections, which poses safety hazards and increases energy consumption of water pumps. At present, people have recognized these problems and started qualitative research, and have been guiding engineering applications, but the energy-saving effect is limited to qualitative analysis, and there is no corresponding experimental method for quantitative research on its overall operating energy consumption. The test and evaluation method of the present invention provides a simple and practical test plan and evaluation method, which can not only qualitatively verify whether the exhaust valve in the pipeline has the effect of reducing energy consumption, but also quantitatively evalu...
