Cov ntsiab lus rau kev mloog

Proportional solenoid valve

Nws ua haujlwm li cas:

Tag nrho cov solenoid valve Cheebtsam yog electromagnetic kauj nyob rau hauv cov nqe lus ntawm hluav taws xob ib feem, uas yog, inductor. Thaum lub inductor tau txais cov teeb liab hluav taws xob, cov hluav taws xob hluav taws xob tsim los ntawm qhov tam sim no yuav ua rau lub valve core txav thiab paub txog qhov kev hloov pauv ntawm cov tswj tsis tau.
Kev txheeb xyuas qhov zoo:
Txhua lub electromagnetic coil muaj qhov ruaj khov tus nqi R, tab sis qhov R no tsis tuaj yeem yog "0" lossis "∞", thaum R = "0" qhia qhov luv luv Circuit Court: thaum R = "∞" qhia qhov qhib Circuit Court; nrog
Qhov kev tiv thaiv ntawm lub kauj rau lub tsev tsis tuaj yeem yog "0". Yog tias cov xwm txheej saum toj no tuaj yeem ua tau raws li thiab lub solenoid valve tsis ua haujlwm, nws yuav yog tias lub teeb liab tawm tswv yim tsis raug lossis lub valve core yog daig.

Siab sensor

Nws ua haujlwm li cas:

Rau peb-xaim siab sensor, nws tuaj yeem nkag siab tias peb-xaim potentiometer lossis qhov sib txawv ntawm cov resistor, feem ntau ntxiv 5V voltage rau ob ntawm kab (1 kab thiab 3 kab), thiab thaum ntsuas tus nqi hloov, qhov voltage ntawm cov kab nruab nrab (2 kab) hloov ntawm 0 thiab 5V.

Kev txheeb xyuas qhov zoo:
1. Ua cov kab hauv nruab nrab, hloov lub teeb liab ntsuas, siv lub ntsuas ntsuas ntsuas seb qhov voltage ntawm kab nruab nrab (2 kab) hloov nrog lub teeb liab ntsuas.
2. Hla lub sensor tsis muaj qhov txhaum

Lub hauv paus ntsiab lus ua haujlwm ntawm proportional electromagnetic tswj valve yog qhia

Nws yog raws li lub hauv paus ntsiab lus ntawm solenoid on-off valve: thaum lub hwj chim tawm, lub caij nplooj ntoos hlav nias lub hauv paus ncaj qha rau lub rooj zaum, ua rau lub valve kaw. Thaum lub coil yog energized, lub electromagnetic quab yuam generated overcomes lub caij nplooj ntoos hlav quab yuam thiab nqa cov tub ntxhais, yog li qhib lub valve. Lub proportional solenoid valve ua rau qee qhov kev hloov pauv rau cov qauv ntawm lub solenoid valve: nws tsim qhov sib npaug ntawm lub caij nplooj ntoos hlav quab yuam thiab lub zog electromagnetic nyob rau hauv ib co coil tam sim no. Qhov luaj li cas ntawm lub kauj tam sim no lossis qhov loj ntawm lub zog hluav taws xob yuav cuam tshuam rau lub plunger stroke thiab valve qhib, thiab lub valve qhib (ntws) thiab lub kauj tam sim no (tswj lub teeb liab) yog qhov zoo tshaj plaws kev sib raug zoo. Direct acting proportional solenoid valve ntws hauv qab lub rooj. Qhov nruab nrab ntws los ntawm hauv qab lub rooj zaum, thiab cov kev taw qhia ntawm lub zog yog tib yam li lub zog electromagnetic, thiab qhov ntxeev ntawm lub caij nplooj ntoos hlav quab yuam. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau teeb tsa qhov loj thiab me ntws qhov tseem ceeb sib haum rau kev ua haujlwm ntau (coil tam sim no) hauv lub xeev ua haujlwm. Lub proportional solenoid valve ntawm Drey kua yog kaw (NC, ib txwm kaw hom) thaum lub hwj chim tawm.
