Do anti-corrosion dust instrument in chemical industry

Are indispensable instrument industry, chemical instrumentation monitoring equipment, it maintain the function of the chemical production line smooth operation, also can protect life and property safety. For chemical also use the instrument, instrument equipment exposed for a long time, weathered the instrument is easy to fail, then it need us to do a good job of anti-corrosion, shock and dust instrument, instrument daily maintenance and check management can not only improve the precision of instrument, can prolong the service life of instrument, the following will follow a thermometer to know about the factory, how the anti-corrosion field instruments and dust! 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer anti-corrosion maintenance:

the field instruments when ordering reasonable choice materials targeted choose corrosion of metal or nonmetal materials to make the parts, is the foundation of industrial instruments anti-corrosion methods. For example, made of titanium, tantalum metal instrument parts, to learn chloride medium has a strong corrosion resistance; Made of ptfe material instrument parts and gasket, also widely used in all kinds of corrosive medium environment. 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

add protection: protective layer on the instrument parts or components made from, is very common in industrial anti-corrosion methods. In accordance with the protective layer of different materials and the forming principle, can be divided into the following three kinds: 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

a. Metal protective layer. Including spraying, electroplating, hot dip, carburization, etc. 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

b. Non-metallic protective layer. Such as paint, acid-resistant cement, rubber, plastic, enamel, etc. ; 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

c. Non-metallic protective film on metal surface for chemical treatment, to generate the oxide film, phosphate film protective film; 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

diaphragm isolation: using the corrosion resistance of the diaphragm spacer or filling liquid and segregated measured medium, corrosion protection purposes. It is suitable for the corrosive medium, to use tube isolated or container, usually suitable for pressure measurement, should not be measured with a differential pressure. Isolation diaphragm should be flexible and impermeability, such as common diaphragm pressure gauge, single flange anticorrosive pressure transmitter, etc. 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer of dustproof

the field instruments maintenance: instrument external dust method is the shield on the bonnet instrument or in sealed box. For dust and impurities in the measured medium and particles such as protection, in addition to adopt measures to prevent such as reducing dust jam, usually adopt bold intake pipe installation of blowing device, adding dust catcher, and equipped with protection methods such as screen. Coarse intake pipe joint use often, purging and filter device. When using do not carry the ring chamber orifice measuring flow, pressure will be back in the mouth with 1 directly. 5 ~ 2 m bold intake pipe, equipped with plug, so as to produce the hole cleaning during maintenance or for emptying. Level measurement, in order to prevent negative pressure tube generates crystallization, is used for the suction pipe can blow steam condensate. For gas containing moisture measurement, can be used in a water separator, which is common in the pressure and flow measurement. 2 fg magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
