Precautions for boiler thermometer

Entering the gas boiler room, you will find a lot of thermometers and pressure gauges, through the measurement of temperature and pressure, to achieve the monitoring of the entire system. So what are the precautions for installing thermometers and pressure gauges? Let's introduce them separately.

Precautions for thermometer installation

1. The temperature sensing body of the thermometer needs to be fully extended into the pipeline, the insertion depth of the thermometer = the length of the instrument connector + the wall thickness of the pipeline + the immersion length (the thermocouple in liquid environment is based on 60mm, the thermal resistance and bimetal thermometer is based on 80mm, and the thermocouple in gas environment According to 45mm gauge, thermal resistance and bimetal thermometer according to 65mm gauge).

2. When the vertical installation length is not enough, you can consider inclined installation. The installation method is inclined 45 degree installation, the direction is opposite to the medium flow direction.

3. Pipes with smaller diameters can also be installed with expanded pipes to meet the measurement conditions.

Precautions for pressure gauge installation

1. The installation position is on a straight pipe section with stable flow, generally meeting the rules of the first five and then ten, and at least the first three and the eight rules.

2. The pressure gauge should not be located at the bottom of the pipeline.

3. The pressure gauge on the vessel should be set up in the gas phase.

The above are the precautions for the installation of boiler thermometers and pressure gauges.
