X'inhu gauge tal-pressjoni u kif jaħdem?
Gauge tal-pressjoni huwa strument tal-kejl użat biex ikejjel il-livelli tal-pressjoni f'likwidi jew gassijiet madwar l-industriji. Huwa strument vitali għaliex jgħin ukoll biex jikkontrolla l-livelli tal-pressjoni fil-likwidi u l-gassijiet u jżommhom fil-limiti meħtieġa. Jekk il-pressjoni taqbeż, tinstema 'allarm. Mil-lat tas-sigurtà, dan huwa importanti għaliex jekk il-livell tal-pressjoni jinqabeż u jitħalla inosservat għal żmien twil, l-istrument jew il-magna jistgħu jisplodu. Dan jista 'jweġġa' lill-ħaddiema u jagħmel ħsara lit-tagħmir. Għalhekk, il-gauge tal-pressjoni huwa importanti ħafna għas-sigurtà ġenerali tal-impjant. Dan l-artikolu jiddiskuti l-prinċipju tax-xogħol u dettalji oħra tal-gauge tal-pressjoni.
Nitkellmu dwar il-prinċipju tax-xogħol tal-gauge tal-pressjoni
The working principle of the pressure gauge is based on Hooke's law, which states that the force required for a spring to expand or compress is linearly related to the distance of extension or compression. There are internal pressure and external pressure. Therefore, when pressure is applied to the surface of an object, the pressure on the inner side is greater due to the smaller area under pressure. Bourdon pressure gauges are widely used in all walks of life, and this is how they work.
Il-gauges tal-pressjoni diġitali issa jintużaw b'mod komuni. Għal gauges tal-pressjoni diġitali, il-provvisti tal-enerġija AC u DC għandhom rwol importanti. Ċirkwit tal-bidla jew konverżjoni ta 'kurrent alternanti għal kurrent dirett. Il-pressjoni mkejla tiġi trażmessa lid-dijaframma tas-sensorju, u d-dijaframma tas-sensorju tħoss il-pressjoni. Ibbażat fuq dan, sinjal elettriku huwa ġġenerat biex jilħaq il-kompjuter jew smart phone. Dawn il-meters huma mgħammra b'display LCD żgħir.
Dettalji oħra importanti tal-gauge tal-pressjoni
Pressure gauges range from basic measuring to fully automated, and can be connected to your smartphone to send alerts. The pressure sensor is an important part of the pressure gauge. There are many types of pressure gauges on the market, such as commercial pressure gauges, general service pressure gauges, stainless steel industrial pressure gauges, differential pressure gauges, double-sided pressure gauges, etc. With so many choices, it's obvious to be confused. Among various factors, the scale of the application must be one of the key considerations when selecting a pressure gauge for any process. These pressure gauges require regular maintenance and maintenance, because a pressure gauge that is out of service poses the same threat to the factory as there is no pressure gauge. Therefore, it is always better to have a small number of well-served meters in your factory. From an accuracy point of view, the installation and correct calibration of the pressure gauge are important aspects.
Iffoka fuq gauge tal-pressjoni b'żewġ-naħat
Il-gauge tal-pressjoni b'żewġ-naħat huwa wieħed mill-aktar tipi importanti ta' gauge tal-pressjoni. Jintużaw ħafna fl-industriji kimiċi, taż-żejt u tal-gass. Dawn li ġejjin huma xi karatteristiċi ta' benefiċċju ta' gauges tal-pressjoni b'żewġ-naħat:
Huma magħmula prinċipalment minn korp tal-plastik u għandhom disinn b'saħħtu-heavy duty.
Huma reżistenti għal kimiċi, korrużjoni, materjali li joborxu, temperaturi għoljin, eċċ.
Huma preċiżi ħafna u kompatibbli f'firxiet ta 'pressjoni multipli.
Għandhom dijaframma tat-Teflon tubu Bourdon.
M'għandekx bżonn timla dawn il-meters, għax huma mimlijin minn qabel-bil-gliċerina jew fluwidu tal-meter tas-silikon ottiku.
Huma mgħammra b'lentijiet tal-polikarbonat, reżistenza għall-impatt għolja u wirjiet tal-kulur b'tikketti ta 'firxa qawwija.
Huma għandhom skali doppji, u tista 'tagħżel l-unità bejn PSI/KPA u PSI/BAR.
Għandhom mekkaniżmu ta 'allarm f'każ li l-filtru jew il-borża jeħtieġ li jiġu sostitwiti.
Dawn japplikaw anke f'żoni fejn il-viżibilità hija problematika. Tista 'tinstallah fuq magni jew pompi kimiċi f'dawn iż-żoni.
