Industrial differential pressure control equipment detection method

Abstract

The invention discloses an industrial differential pressure control equipment detection method, and belongs to the technical field of differential pressure control equipment detection. The device usedin the detection method comprises a pressure console (internally provided with a gas preloading pump), a digital pressure calibrator A, a digital pressure calibrator B, a processor, a booster valve,a low-pressure valve, a balance valve, a pressure release valve, a gas capacitance tank A and a gas capacitance tank B, and a gas preloading pump is arranged in the pressure console, and a pressure increasing valve is mounted between the output end of the pressure console and the gas capacitance tank A. According to the invention, data acquisition and verification of static pressure in a pipelinein a balanced state are collected through devices such as a digital pressure calibrator and a processor. After data acquisition, data verification and comparison are carried out by taking a national standard regulation rule of the differential pressure controller as a data reference, and whether the static pressure of the differential pressure controller is qualified or not can be judged after data comparison, so that static pressure detection of the differential pressure controller is realized.

Description

technical field [0001] The invention relates to the technical field of differential pressure control equipment detection, in particular to a detection method for industrial differential pressure control equipment. Background technique [0002] The differential pressure controller can use a variety of sensors, such as bellows type sensors, diaphragm type sensors, which can be used for gas, liquid and other media. The setting value of the controller is adjustable, the adjustment range is 10-2500Pa, and the working pressure range is 0-0.1Mpa. High sensitivity, low control value, small switching difference, ultra-small design. [0003] In industrial production, the quality of the differential pressure controller directly affects the safe operation of the entire production chain. In the daily verification of metrology verification departments at all levels, due to the lack of suitable verification methods, the static pressure influence of the differential pressure controller is...

AI Technical Summary

Problems solved by technology

In the daily verification of metrology verification departments at all levels, due to the lack of suitable verification methods, the static pressure influence of the differential pressure controller is often ignored. Under the influence of static pressure, the measurement accuracy of the differential pressure controller will be greatly affected. The verification of pressure may cause deviation and misjudgment of the pressure verification results, so it is necessary to detect the static pressure of the differential pressure controller. For this reason, we propose a detection method for industrial differential pressure control equipment
