Kungani inzwa yokudlidliza ibaluleke kangaka enjinini? Iyini isimiso sayo?

Inzwa yokudlidliza ingenye yezingxenye ezibalulekile kubuchwepheshe bokuhlola. Inezinzuzo zezindleko eziphansi, ukuzwela okuphezulu, ukusebenza okuzinzile nokuthembekile, kanye nobubanzi obukhulu bokutholwa kokudlidliza obulungisekayo. Isetshenziswa kabanzi emikhakheni eminingi njengamandla, imboni yamakhemikhali, imithi, izimoto, i-metallurgy, ukukhiqizwa kwemishini, imboni yezempi, ucwaningo lwesayensi kanye nokufundisa.

Kunoma yiluphi uhlelo lokulinganisa ukudlidliza, ithuluzi eliphambili yi-vibration sensor. Lidlala indima ebalulekile ekulinganisweni kokudlidliza. Njengoba izinga lobuhlakani lithuthuka njalo kanye nezidingo zokuthembeka okuphezulu kwemishini, ukuqapha isimo se-inthanethi se-drive motor kanye nempendulo yesikhathi sangempela yesikhundla kanye nezimpawu zesivinini kuvame ukuba yinto ejwayelekile. Ukusetshenziswa kwezinamathiselo ze-motor ezifana nama-encoder, ama-overspeed switch, i-PT100, i-PTC, izinzwa zokudlidliza, njll. kuya ngokuya kuvama. Kubaluleke kakhulu ukuthi abakhiqizi bemishini baqonde lezi zinamathiselo futhi baqaphele ukuhlanganiswa kwazo kwemvelo nemoto.

Isibonelo, kweminye imishini, kuyadingeka ukuqapha ukudlidliza kwezingxenye ezithile. Kuyadingeka ukufaka izinzwa ngesikhathi senqubo yokufaka ukuqapha ukudlidliza ngesivinini esihlukene ukuze kufezwe injongo yokuqapha kanye nokugcinwa okunembile ukuze kuncishiswe umonakalo wemishini.

Uma isidingo sokuphendula imvamisa singephezulu kakhulu, ungasebenzisa inzwa engu-4-20mA enokukhipha isivinini, uqoqe idatha nge-PLC, futhi uqaphe inani lejubane le-RMS. Noma sebenzisa ithuluzi lokubonisa ukuze uthole inkomba yokuqapha endaweni. Uma isidingo sokuphendula imvamisa siphezulu, ungasebenzisa inzwa engu-4-20mA enokukhipha ukusheshisa, noma usebenziseACokukhipha isignali. Nge-PLC esheshayo noma ikhadi lokuthola, qoqa amanani okusheshisa bese uqala izenzo zokuvikela ezilandelayo ngesikhathi sangempela.

Izinzwa zokudlidliza zisetshenziswa kabanzi ezimbonini ezahlukene: njengokucubungula insimbi, ukukhiqizwa kwesimende, imboni yokwenza amaphepha, imboni yasolwandle, ukumba izimayini nokumba, ukukhiqizwa kwamandla omoya, ukudla neziphuzo, imboni yemithi, ezokuthutha ngesitimela, ukukhipha uwoyela negesi, imboni yamandla kanye neminye imboni.
