Indlela yokukhetha inzwa yokucindezela

Iluphi uhlobo lokucindezela olukalayo olokuqala lwenzwa yengcindezi ekhethiwe.inzwa yokucindezela ihlukaniswe ingcindezi yemishini kanye nengcindezi (hydraulic), iyunithi yokucindezela komshini ngokuvamile i-N, KN, KGf, i-pressure hydraulic unit ngokuvamile i-KPa, i-MPa, i-PSI, njll.
Ake sikhulume ngokukhethwa kokucindezela kwemishini.
1) Mayelana nokucindezela komshini: into yokuqala okufanele uyicabangele ukukala ingcindezi noma ukungezwani, uma kukhona kuphela ukukala ingcindezi, khetha inzwa yokucindezela, uma udinga ukukala ukungezwani, udinga ukukhetha inzwa yokucindezeleka.
Ngaphezu kwalokho, uma udinga ukuxhuma i-tooling noma i-indenter, kungcono ukhethe inzwa yokucindezela kwengcindezi ukuze wenze lula ukucaciswa kwamathuluzi.Uma ikhasimende likhetha inzwa yokucindezela kwamandla, inzwa yokucindezela ukuze icindezele phansi, cindezela kuqala kuthuluzi, bese uqhubeke ucindezela phansi, kuze kube umkhiqizo .Ngale ndlela, inzwa yokucindezela iyaphoqeleka, bese umkhiqizo ungamandla, Izinzwa zokucindezela kanye nemikhiqizo ingaphansi kwamandla ahlukene, Umkhiqizo ngokwawo ungaphansi kwamandla amancane kunenzwa yokucindezela, Lapho isakhiwo senziwe, ikhasimende ingangeza kuphela inani lesinxephezelo kuhlelo lwe-PLC.Lesi simo singagwenywa ngokuphelele uma inzwa yohlobo lokudonsa-press ikhethiwe futhi inzwa nokusetshenziswa kwamathuluzi kuxhunywe ndawonye.

2) ukukhethwa kobubanzi bokulinganisa, ukuze kugwenywe ukulimala kwenzwa ngenxa yomthwalo omningi, ebangeni lokunemba elivunyelwe, kufanele libe likhulu ngangokunokwenzeka.Uma kusetshenziswa isilinda noma isilinda kagesi, ubukhulu be-thrust yesilinda noma isilinda kagesi kufanele kubalwe, okuhlanganisa amandla okuthinta.

3) ukukhethwa kosayizi wenzwa yokucindezela, njengokuthi akukho mkhawulo endaweni yokufaka, ungakhetha usayizi omncane wenzwa, izinzwa ezinkulu ngokuvamile zinezimbobo ezinezintambo ezansi, kulula ukuzifaka, ngokuqondile. elungiswe ngezikulufo, ingasindisa inkinga yokucubungula izinto.Ngaphezu kwalokho, ngokuvamile usayizi wenzwa enkulu unembe kakhulu.

4) Ukushisa kunomthelela othile emsebenzini wezinzwa, ukukhethwa kwenzwa yokucindezela kufanele futhi kucabangele isici sokushisa, njengokushisa kwemvelo kuphezulu kakhulu, kufanele kuchazwe kumenzi, ukukhethwa kwenzwa yokushisa ephezulu.

5), Ngenxa yokuphuma kwenzwa yokucindezela kuyisignali ye-millivolt, isignali akuyona isignali ye-analog ejwayelekile, isidluliseli kufanele sinikezwe, esibizwa nangokuthi i-amplifier, isignali ibe isignali ye-analog evamile noma isignali yedijithali, njenge-analog evamile 4- 20mA, 0-5V, 0-10V, digital RS232, RS485, njll.

I-6) Uma isidingo sokubonisa esizeni, kuyadingeka ukufanisa ithuluzi lokubonisa, ithuluzi lokubonisa kanye nokudlulisa izinketho ezimbili.Ku-PLC noma olunye uhlelo lokutholwa, ithuluzi lokubonisa elinomphumela we-analog noma ukuxhumana kwe-serial kufanele kukhethwe.
