1. Prevent vibration and collision:
Pressure gauges should be protected from strong vibrations and collisions to avoid affecting their measurement accuracy and stability.
2. Keep the dial clear:
It should be ensured that the pressure gauge dial is clear and unobstructed in order to accurately read the pressure value. At the same time, it is necessary to regularly check whether the pointer rotates and fluctuates normally to ensure accurate readings.
3. Regular inspection and maintenance:
Pressure gauges should be regularly calibrated to ensure their measurement accuracy. It is strictly prohibited to use pressure gauges that are unqualified, have no lead seals, unclear scales, malfunctioning pointers, or externally damaged.
The connecting pipe of the pressure gauge should be regularly flushed to prevent blockage and keep it unobstructed.
4. Choose a suitable pressure gauge:
Select the appropriate pressure gauge according to actual needs, including measurement range, accuracy level, working environment, etc., to ensure the accuracy and reliability of measurement results.
5. Pay attention to the usage environment:
The pressure gauge should be used within the specified range of ambient temperature and medium temperature to avoid the influence of high or low temperature environment on measurement accuracy.
When measuring high-temperature media or steam, a circular tube should be installed in front of the pressure gauge to protect the elastic element from being affected by high temperature and changing its elasticity.
6. Control operation specifications:
During use, the opening and closing speed of the valve should be controlled to reduce water hammer and avoid impact on the pressure gauge.
The pressure gauge should avoid being in a high-pressure state for a long time to prevent damage or inaccurate measurement.
7. Pay attention to the pressure pipe and seal:
The thickness and length of the pressure conduit should be appropriate to reduce the delay in pressure indication. The installation of pressure pipes should ensure an appropriate inclination to facilitate the discharge of accumulated liquids or gases.
Suitable sealing gaskets should be installed at the connection between the pressure gauge and the pressure pipe to ensure good sealing performance and prevent medium leakage.
Following the above precautions can ensure the normal use and measurement accuracy of the pressure gauge, thereby ensuring production safety and equipment operation stability.
