Pressure gauge installation must know the matters, it is worth a look!

Pressure gauge is very common in industrial production, more is installed on the pipeline, pipe and the material being measured, the installation of the matters needing attention are also different, today small make up you explain for everybody. Installed on the pipeline pressure gauge, generally choose 100 mm diameter can surface, such as the installation location is higher, when the poor lighting conditions; Can choose 150 mm or 200 - a - 250 - mm. Before installation to calibrate the pressure gauge, eligible to install and use. Pressure gauge when installation should be fixed on the joint of special processing, and should add gasket; And don't take hemp lace or directly on the valve. The most important of all, pressure gauges shall be installed at the site where the easy operation and maintenance. To guarantee the accuracy of the measurement, pressure points shall be representative. As should choose in the smooth flow of straight pipe section, not in pipe bending, corner; Take pressure pipe generally not into equipment and pipeline. To take pressure point location and certain requirements, in horizontal and inclined pipes, for example: a, when the medium is gas, half on the pipeline. Second, the medium of steam, half in the line and horizontal centerline to 0 Within the scope of the Angle of 45 degrees, the best in the center of the pipe horizontal line. Three, for the liquid medium in pipe and horizontal centerline to 0 at the lower & ndash; 45 degree Angle range. Because conditions, such as when, can choose a reasonable position according to actual situation. Installation of water vapor pressure gauge or medium temperature over 80 degrees, to prevent overheating and damage the instrument elements, between the pressure points and pressure gauge valve should add ring or u-shaped bend, is the good partner pressure gauge & ndash; — Siphon. When measuring the compressor or the pulsation of the pump outlet pressure, in order to protect the pressure gauge and measurement accuracy, can be in front of the pressure gauge with buffer or choke; When necessary, can be mounted to the damping valve, the pressure changes, increase the resistance to pressure gauge. Measuring medium containing dust, particles or impurity occasions should take bold pressure pipe, dust collector or drain valve when necessary, to purge guide tube, the wet gas should be equipped with water separator. Installing a low pressure gauge, should try to avoid the static pressure of liquid column for instrument measurement. For key equipment of pressure measurement, respectively device two pressure gauge, in case of accident. Pressure gauge and pressure points distance should be shorter. To avoid measurement lag, guide tube should not exceed 50 meters, such as too long, can consider to use the remote pressure gauge, for easy to crystallization, blocked medium should install union, so as to remove the blow wall in the future. In order to guarantee the reliability of the pressure measurement and production safety, in addition to the regular maintenance inspection, must according to the time limit stipulated by the test pressure.
