Yolula ukupakishwa kwefilimu ngoomatshini kunye nokhuseleko lwamandla ombane.
Njengenye yevacuum ezenzekelayo
umatshini wokupakisha Umatshini wokupakisha wefilimu owolula, iimoto zawo zangaphakathi okanye izinto zombane zisebenza phantsi kombane olinganisiweyo, amandla ombane aphezulu kakhulu, aphantsi kakhulu okanye into eyenziwa ngumntu kwinkqubo yokusebenza iphelelwa ngamandla ngequbuliso, inokubangela umonakalo kwizixhobo okanye kwiingxwelerha zabasebenzi, ngoko ke Uyilo lwesekethe yokulawula umbane, ngokweemfuno zangempela, ukuseta ukhuseleko, ukhuseleko lombane kunye nokulahleka koxinzelelo phantsi kokhuseleko lombane.

Ukupakisha ifilim yokupakisha ukhuseleko lwamandla ombane ombane ongu-0, ukhuseleko lombane ophantsi
yolula ukupakishwa kwefilimu ngoomatshini kunye nokhuseleko lombane wombane.
Umatshini wokupakisha wokucoca ifilimu xa kukho igridi yamandla emsebenzini ngequbuliso ukusilela kombane, imoto iya kuma, nayo iya kuyeka ukuveliswa kwezinto ezihamba ngoomatshini.
Ngokuqhelekileyo abaqhubi abanakukwazi ukutsala ngexesha elifanelekileyo ukuvula iswitshi yamandla, ukuba akukho nto yenziweyo, xa ifilimu yokucoca i-vacuum yokupakisha i-voltage yombane kunye nomthombo wombane ibuyela kwimeko yesiqhelo, i-motor iya kuqalisa ngokwayo, inokubangela iingozi zabaqhubi kunye nezixhobo, kwaye amandla phezu kwangoku kunye nokuhla kwamandla ombane wenethiwekhi ngoko nangoko.
Ngoko ke kufuneka uthathe amanyathelo okukhusela i-voltage zero.
kumgca wokupakisha we-membrane yokulawula i-tensile, i-voltage ye-zero ngu-contactor kunye nokukhusela okuphakathi kwe-relay.
Xa umbane wegridi ucima, i-contactor kunye ne-intermediate relay current yanyamalala, i-contactor reset, ukunqumla umbane ongundoqo wesekethe kunye nolawulo lwesekethe.
xa upakisha ifilimu yolulwe ngoomatshini kunye nomthombo wombane wombane ubuyela kwinto eqhelekileyo, ukuba ayicofa iqhosha lokuqala, i-motor ayizukuziqalela ngokwayo, kunye nokhuseleko lwe-voltage ye-zero xa i-voltage yegridi, i-motor iya kuhamba phantsi kombane ongaphantsi kombane, isantya semoto siyehla. , i-stator winding current yongezwa.
Ngenxa yokuba akukho amplitude yaneleyo yangoku okongezwayo ukwenza i-fuse kunye nesenzo sokuhanjiswa kwe-thermal, akunikezeli ukhuseleko, ngoko ke ezi ntlobo zimbini zezixhobo zombane ukuba azithathi manyathelo okukhusela, ziyakwandisa kakhulu umonakalo wemoto ekuhambeni kwexesha.
kwelinye icala, i-voltage enetyala iya kubangela ukukhutshwa kombane, ukwenza isekethe ingasebenzi, kunokukhokelela kwingozi yomntu kunye nezixhobo.
Ke kufuneka uphephe ukuhamba kwemoto phantsi kombane ophantsi.
esona sixhobo sombane sikhusela umbane sisixhobo sombane sombane kunye nesinxibelelanisi.
Kwisekethe yolawulo yombane yokupakisha ifilimu eyolulayo, yimigca embalwa kuphela efakelweyo ekhethekileyo yombane wombane onendima yokukhusela umbane ophantsi, kwaye ngenxa yokuba uninzi lonxibelelwano lwesekethe yolawulo kwaye inomsebenzi wokhuselo lombane ophantsi, ke ngoko musa ukongeza ukhuseleko lombane ophantsi. izixhobo zombane, ngokubanzi xa amandla ombane egridi athotywa abe ngaphantsi kwamashumi asibhozo anesihlanu eepesenti zombane olinganisiweyo, i-voltage relay contactor okanye isenzo, ukunqumla isekethi engundoqo kunye nolawulo lombane wesekethe, ukwenza imotor ime.

Yolula ifilimu ukupakishwa ngoomatshini kunye nokukhuselwa kwamandla ombane wokukhusela ukugqithiswa kombane
yolula ukupakishwa kwefilimu ngoomatshini kunye nokhuseleko lombane wombane.
I-electromagnetic, i-sucker ye-electromagnetic kunye nomthwalo omkhulu we-inductance kunye namaziko e-electromagnetic e-DC, i-dc relay, njl. Ngokubanzi, iya kuvelisa amandla aphezulu okwenziwa kombane we-electromotive, iya kwenza ukuqhawuka kunye nomonakalo wekhoyili ye-electromagnetic.
Ngoko ke kufuneka uthabathe ukhuseleko overvoltage.
Ngokwesiqhelo kwisekethe yonxibelelwano lomatshini wokupakisha ifilimu, i-resistor kunye ne-capacitor ngokuhambelana kuzo zombini iziphelo zekhoyili, kwisekethe ye-dc, kwi-diode ngokunxuseneyo kuzo zombini iziphelo zekhoyili, ukuze yenze isekethe yokukhupha, ukukhuselwa kwe-overvoltage. .
Ukuxhomekeka okukhulayo kusetyenziso lwe-weigher checkweigher yenze utshintsho oluninzi kwishishini le-
multihead weigher kumashumi eminyaka adlulileyo.
Ngaphezu kwako konke, silindele ukuba lityala kuluntu esilusebenzelayo, isixhobo esixabisekileyo kubathengi bethu, kunye nendawo apho isikali sethu esizinikeleyo sinokukhula kwaye siphumelele.
Umlinganiselo wokulinganisa umatshini yinkqubo yonke ye-servo ekwazi ukugcina amakhulu eeparamitha zenkqubo yokujonga ukubonelela ngeeprofayili zesiko le-multihead ye-weigher yodidi ngalunye kunye noqwalaselo lwe-checkweigher.
I-
multihead weigher ingalungiswa ukuze isetyenziswe nakuwuphi na umatshini wokulinganisa kwaye ifanelekile kwi-checkweigher.
