Pressure gauge of adaptation and maintenance should be paid attention to what?

Pressure gauge in the heat pipe network, oil and gas transmission, water supply, gas supply system, vehicle maintenance factory stores in areas such as 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. Pressure gauge of adaptation and maintenance should be paid attention to what? 1) Should be used when the instrument must be installed vertically: 17 mm wrench to tighten, should not strong torsional case; Transportation should avoid collision. 2) Use appropriate at ambient temperature for - meter 25~55℃。 3) Using work environment vibration frequency & lt; 25 hz, the amplitude is not more than 1 mm. 4) Used for high temperature indicating value of the instrument is not back to zero or appear, indicating error can cut open upper case sealing rubber plug, make instrument lumen and atmosphere are interlinked. 5) Instrument use scope, should be between 1/3 to 2/3 of the ceiling. 6) In corrosive media, possible crystallization medium, the viscosity of the larger media should add isolation device. 7) Instrument should be regular check ( At least once every three months) , if discover fault should be timely repair. 8) Instrument from the date of delivery, if half a year under normal storage conditions of use found failure or damage due to poor quality, by the company responsible for repair or exchange; 9) Need a measuring instrument of corrosive medium, should indicate the requirement when ordering.
