Pressure gauge calibration device capable of simultaneously detecting a plurality of gauge bodies

Abstract

The invention discloses a pressure gauge calibration device capable of simultaneously detecting a plurality of gauge bodies. The device comprises a calibration platform, an oil supply mechanism, a support frame, a touch display screen, a PLC (Programmable Logic Controller) control system and a high-precision standard pressure gauge body. The oil supply mechanism is fixedly arranged at the left upper part of the calibration platform, the support frame is integrally fixed to the upper portion of the rear end of the calibration platform, the touch display screen and the PLC control system are fixed to the front side face of the left end of the support frame, the PLC control system is connected to the lower portion of the touch display screen, an oil conveying pipe is connected to the right end of the oil supply mechanism, the upper portion of the oil conveying pipe is connected with a first connecting pipe and a second connecting pipe through sealing bearings, and the second connecting pipe is arranged on the right side of the first connecting pipe. According to the pressure gauge calibration device capable of simultaneously detecting the multiple gauge bodies, the mode that the oil pressure of an original calibration platform needs to be manually adjusted is changed, different calibration parameters can be set according to needs, and the calibration precision is high and can reach 0.05%.

Description

technical field [0001] The invention relates to the technical field of pressure gauge calibration devices, in particular to a pressure gauge calibration device capable of testing multiple gauge bodies at the same time. Background technique [0002] The pressure gauge is an instrument used in various fields to detect the pressure of the liquid and gas being transported. The pressure of the liquid or gas is detected through the pressure gauge, so that it is easy to know the status of the liquid or gas being transported. Whether the process is safe or not, the pressure gauge needs to use a calibration device to calibrate the pointer of the pressure gauge during production. Although there are many types of pressure gauge calibration devices on the market, there are still some deficiencies in the process of use. ,for example: [0003] 1. Most of the existing pressure gauge calibration devices need to be manually operated when they are in use. First, they need to manually compare...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a pressure gauge calibration device that can detect multiple gauge bodies at the same time, to solve the above-mentioned background technology. Manual operation requires manual comparison between the standard meter and the meter to be calibrated, and the calibration accuracy is poor. Second, only one meter can be calibrated at a time, which is inefficient and will seriously slow down when faced with large-scale maintenance projects. Maintenance progress, when the existing pressure gauge calibration device needs to install and disassemble multiple gauges to be calibrated, the staff need to install and disassemble them one by one, which not only increases the workload of the staff, but also takes time strenuous problem
