Pressure gauge installation considerations

Pressure gauge, English name: pressure the gauge) Refers to elastic element as the sensitive element, measure and instructions above environment pressure meter, the widespread application, it almost throughout all of the industrial process and research fields. In the heat pipe network, oil and gas transmission, water supply, gas supply system, vehicle maintenance shop, etc can be seen everywhere. Especially in the process of industrial process control and technology measure, due to the flexibility of mechanical pressure gauge sensor has high mechanical strength and production is convenient wait for a characteristic, make the mechanical pressure gauge is widely used. The working principle of pressure gauge is a sensitive element (by table Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure. Instrument for share pressure gauge installation considerations. Pressure gauge to precision instrument, in the process of handling, installation and use, should avoid to impact and vibration. 1. Hold pressure tapping with the hand, gently tighten screw tooth fixed on the device, cannot twist header of avoid by all means, do not use the header when the wrench. 2. Use 2 a wrench and tighten the fixed at the same time, a wrench stuck pressure tapping, a joint wrench stuck equipment, screw fastening due to equipment. 3. Running device, slowly open and close the valve, avoid sharp increase and decrease pressure, cause the pressure gauge is not zero, accuracy is not allowed.
