Background

And the pressure transmitter verification experiment table is used for installing a standard pressure module and a detected pressure transmitter to an output port of the pressurizing pump during operation, wherein '+' of the transmitter is connected with DC24V (+) of HX6100, and '-' of the transmitter is connected with current measurement (+) of HX 6100. Pressing a pressure pump switch below HX6100, then slowly opening a pressure increasing valve, seeing that the pressure value on HX6100 is increased to the measuring lower limit value of the detected pressure transmitter, closing the pressure regulating valve, sealing for 15 minutes, and having no leakage. And opening the pressure relief valve to completely relieve the residual pressure, and then closing the pressure relief valve. And according to the measuring range of the pressure transmitter to be detected, dividing the measuring range into five equal parts uniformly, and determining the detection point. And (3) slowly opening the boost valve to enable the pressure to slowly rise to slowly approach the first verification point, properly adjusting the fine adjustment valve, closing the boost valve after the HX6100 display value is stable at the verification point, reading the current value displayed by the HX6100, recording, continuously and slowly opening the boost valve, and executing all the verification points according to the steps.

In this process, it is necessary to ensure the pressure stability. The factors for ensuring the pressure stability include whether the pressure is stable during pressure transmission, whether the gas flow meter for displaying the pressure is used normally, whether the pressure module and the detected pressure transmitter are connected, sealed and firm, and whether the control force of the valve core of the boost valve is stable.

The pressure transmission stability can be adjusted by installing a pressure stabilizer, whether the pressure module and the pressure transmitter to be detected are connected and sealed is a necessary checking step in the installation process, the gas flow meter and the pressure boosting valve are important execution units for operation and display, and the two items are most easily ignored and cannot be replaced frequently. If a problem occurs, the final detection result is directly affected.

According to research, after the existing flowmeter is used for a long time, the rotating part of the turbine generator and the rotating part of the rectifier are abraded or other reasons cause the rotating end of the impeller in the flowmeter to be influenced when rotating, so that the rotation is not flexible, and the flow speed of gas in the flowmeter during moving is influenced, and the measuring accuracy of the flowmeter is influenced. Therefore, when the situation occurs or the flowmeter needs to be disassembled and maintained regularly, the disassembling and the assembling of the existing flowmeter are found to be complicated in the disassembling and the maintaining process, and the internal components are not easy to replace, so that the maintaining time is longer. Therefore, it is long when the flowmeter convenient to dismantle and change inside components and parts comes the improvement maintenance, and it is convenient to install, can guarantee the normal use effect of flowmeter.
