The installation of the spring pressure gauge what problem should note?

The spring pressure gauge when use demanding, for example, pressure gauge, before use must be verification and calibration. Gauges should be regularly check, use for a long time of the cycle should be depending on the use frequency and importance degree. But in determining the basic error in accordance with the instruction before install. Pressure gauge installation method, and the measurement precision, service life and so on has certain relations, so when installation should pay attention to the following: (1) selecting pressure nozzle should be vertical, and the flow of measured medium and pipeline equipment leveled, the lining should not be bossed and burr, in order to ensure the static pressure of measured medium. (2) to take the position of the pressure, should by the pressure of different media in the process piping of different position opening, ensure the continuity of pressure, take a short section persons to single-ended male short thick wall seamless tube, spool of thread end and pipe welding, thread ends connected with female cut-off valve. (3) to measure should be equipped with the cooling tank steam medium corrosive medium should be equipped with isolation tank or the use of diaphragm pressure gauges, measuring tapes should be equipped with dust removal dust medium tank, should be equipped with measuring fluctuating pressure shock absorber, damping valve or install seismic pressure gauge. (4) pressure gauge connection appropriate USES M20 & times; 1. Section 5 live. If the temperature does not exceed 180 ℃, the articulated a ptfe gasket sealing gasket should be adopted. Temperature and pressure is higher need annealing copper pad. (5) when the test ban oil medium, can't use with oil or organic compounds of gaskets, in case of an explosion caused by. The determination of 6 gauge installation position should be conducive to meter reading and maintenance. All landowners, such as the pipe have a protrusion ( Such as temperature measuring element) , apply pressure to get in front of it. Pressure gauge installed correctly, is an important factor meter can guarantee its accuracy. Although pressure gauge structure simple and low cost, but installed correctly or not will affect the service life of pressure gauge and accuracy, can only play when installed correctly in the use of good security.
