For John Deere solenoid vharafu AL177192 Kuvaka michina midziyo Excavator accessoriesvalve

A proportional solenoid valve imhando yakakosha yevharuvhu ye solenoid inopa yakatsetseka

uye kuchinja kunoramba kuripo mukuyerera kana kumanikidza zvichienderana nekupinza kwemagetsi. Mhando iyi inogona

kuiswa sevhavhavha yekudzora. Kuti solenoid vharafu ive yakaenzana, iyo plunger

chinzvimbo chinofanira kudzorwa. Inowanikwa nekuenzanisa plunger nesimba rekunze

kazhinji zvinoitwa nechitubu. Chitubu chinozodzvanyirira kusvika simba rekunze rakaenzana nemagetsi

simba re solenoid. Kana nzvimbo ye plunger ichifanira kudzorwa, ikozvino inofanira kuchinjwa,

zvichikonzera kusaenzana kwemasimba pachirimo. Chitubu chinomanikidza kana kutambanudza kusvika simba

balance inosimbiswa.

             Imwe dambudziko nerudzi urwu mhedzisiro yekukweshana. Kukarukana kunovhiringa chiyero chakatsetseka

pakati pe electromagnetic uye spring forces. Kuti abvise mhedzisiro iyi, akakosha emagetsi ekudzora

dzinoshandiswa. Nzira yakajairika inoshandiswa kune yakaenzana kudzora maitiro e solenoid mavharuvhu

is pulse width modulation kana PWM. Kushandisa chiratidzo chePWM sekupinza kwekutonga kunokonzeresa solenoid

kuisa simba nekudzima nguva dzose pamwero wekukurumidza. Izvi zvinoisa plunger mune inotenderera mamiriro uye

nokudaro kupinda munzvimbo yakagadzikana. Kushandura nzvimbo ye plunger. Iyo pane uye kunze mamiriro e solenoid,

inozivikanwawo seyeduty cycle, inodzorwa.

              Kusiyana neakajairwa pa/kudzima solenoid mavharuvhu, proportional solenoid mavharuvhu anoshandiswa mumaapplication

izvo zvinoda otomatiki kuyerera kwekutonga, senge proportional pneumatic actuators, throttle mavharuvhu, burner

control, etc.
