Fundo Yakugwira Ntchito Ya Mavavu Ghakuŵikamo Mpweya, Mikhaliro, Na Kusankha Mavavu Ghakuŵikamo Mpweya

Fundo yakugwilira ntchito ya .Silinda ya mphepoVavu ya thirotolo

Nkhongono ya throttling yikupangika na mtengo wa vavu uwo ukukhozga payipi ya labala yakusinthasintha, ndipo nkhongono ya mphepo yingagwiliskirikaso nchito kuti yinjire mu malo gha mtengo wa vavu, kufinya payipi ya labala. Valve ya throttle yakusinthasintha yili na kapangikiro kambura kusuzga, kugwa kwakuchepa-kupanikizgika, na kugomezgeka chomene pakugwira ntchito. Iwo ukukhwaskika yayi na kufipiskika ndipo kanandi ukugwira ntchito mu msinkhu wa 0.3 kufika pa 0.63 MPa.

Ntchakusuzga chomene kusintha luwiro lwa vipangizo vya mphepo mwa kugwiliskira ntchito mavavu ghakulongozgera mphepo kuluska kugwiliskira ntchito mavavu ghakulongozgera mphepo gha hayidiroliki chifukwa mphepo yikufinyikizgika. Ntheura, para mukugwiliskira nchito vavu yakulongozgera mphepo kuti yileke kwenda mwaluŵiro, mukwenera kumanya vinthu ivi kuti muleke kukhwaŵa:

(1) Pa payipi pakwenera kuŵavya mphepo iyo yikufumamo.

(2) Kuŵika mafuta pakati pa silinda la Pneumatic na pisitoni kukwenera kuŵa kuwemi.

(3) Valve yakulongozgera kwenda kwa maji yikwenera kuŵikika kuzingilizga silinda la Pneumatic panji mota ya pneumatic nga umo vingaŵira.

(4) Yezgani kugwiriskira ncito nthowa yakulongozgera luwiro lwa throttling ya outlet mwakukwana;

(5) Katundu wakusazgikira wakwenera kuŵa wakukhora. Usange katundu wakufumira kuwaro wakupambana chomene, vipangizo vya hayidiroliki panji vya makina (nga ni pneumatic-hydraulic linkage) vikwenera kugwiliskirika ntchito kuti viwezgerepo kusintha kwa luwiro uko kukuchitika chifukwa cha kusintha kwa katundu.

Fundo yakugwilira ntchito ya Pneumatic cylinderone-way throttle valve ni Vavu yakuphatikizgika yakulongozgera msewu iyo yili na vavu yimoza-way na vavu ya throttle mwakuyana, nga umo vikulongosorekera pa chithuzithuzi icho chikulondezgapo. Para mphepo yikwenda mu nthowa yimoza, nga ni kufuma ku P kuya ku A, nga umo vikulongolera na nthowa iyo yikuchimbira, yikuchimbira kwizira mu vavu ya throttle valve. Para mphepo yikuchimbira mu nthowa yakupambana kufuma ku A kuya ku P, vavu yakuwonera yikujulika kwambura kukhweŵa. Mavavu gha throttle gha nthowa yimoza kanandi ghakugwiriskirika nchito pa kulongozga luwiro na kuchedweska maseŵero gha silinda.

Fundo yakugwilira ntchito ya vavu ya Pneumatic cylinder yakufumiska mphepo yikwenera kuŵikika pa doko la mphepo la actuator (nga ni injini ya pneumatic), ndipo ni vavu yakulongozgera iyo yikulaŵilira umo mphepo yikunjilira mu mlengalenga. Iwo ungasintha waka liwiro la kuyenda kwa actuator yayi, kweni kanandi uli na chigaŵa cha muffler, ntheura ungachepeskaso phokoso la chifuŵa.

Chithunzithunzi chakulondezgapo chikulongora umo vavu ya throttle yakufumiskiramo vyakuthukira yikugwilira ntchito. Fundo yake yakugwilira ntchito njakuyana waka na ya vavu ya throttle. Iwo ukulaŵilira msewu wa mphepo mwa kusintha malo ghakufumiramo kufuma ku doko la throttle 1 na kuchepeska phokoso la msewu kwizira mu mazgu-kupokera mkono 2.

Mikhaliro na Kusankha kwa Mavavu gha Silinda ya Pneumatic

Vavu ya throttle ya silinda ya Pneumatic ndiyo chinthu chakukhumbikwa chomene pa silinda. Ŵanthu ŵanandi ŵakuŵikako mahara yayi ku chigaŵa ichi. Para ŵakusankha chiyelezgero, ŵakughanaghanira waka ø4 panji ø6, panji usange silinda ya Pneumatic njikuru chomene, ŵangasankhaso ø8. Kasi pali vinthu vinyake ivyo mukwenera kuŵikapo mtima?

Mavavu gha throttle ghagaŵika mu kupokera na kufumiska. Nga umo mazina ghake ghakuyowoyera, yimoza yikuponya mphepo para yikunjira ndipo yinyake yikuponya mphepo para yikufumiska mphepo. Usange mphepo yikufuma ku umaliro wa ulusi kufika ku umaliro wa chitoliro cha mphepo ndipo mtedza wakusintha uli na nkhongono yikuru pamanyuma pa kusintha, ni vavu ya throttle yakufumiska mphepo. Mwakupambana, ni vavu yakunjilirapo (ŵanthu ŵanandi ŵakumanya yayi umo ŵangasinthira liwiro la silinda la Pneumatic para ŵaluta ku malo).

Para throttling ya intake yikuchitika, nkhongono iyo yili mu chipinda cha kufumiska mphepo yikuŵa yichoko (yikulumikizgika na nkhongono ya mphepo), ndipo chipinda cha intake chikuzura na mphepo pamanyuma pa kukanizgika kwa mphepo. Mpweya wakuyenda mpweya ndiwo uchoko, ndipo nkhongono yakwamba njakuchepa. Para katundu wa silinda ya Pneumatic ni mukuru, pazamuŵa chinthu chakukhwaŵa ndipo pamanyuma pake chizamukwera. Para mphepo yakufumiskika yikuchepeskeka, chifukwa cha nkhongono ya vavu yakukanizga msewu-, nkhongono iyo yili mu chipinda cha mphepo yizamukhira mwamabuchibuchi yayi kufika pa zero. Pa nyengo iyi, kupanikizika mu chipinda cha kunjilirapo kukuyana waka na kwa mphepo, iyo yingapanga mphambano ya kupanikizika yakukhazikika na kukwaniska kulongozga makora liwiro. Pakuti silinda panji ma blower ghakugwira ntchito ghamoza -, para mukugwiliskira ntchito throttling ya exhaust, vavu ya throttling yikugwira ntchito yayi (ichi nchambura kumanyikwa chomene; awo ŵali mu ungano ŵakuzunulika yayi, kweni awo ŵali mu silinda ŵakumanya yayi), chifukwa msewu ukuchepeskeka na stroke yakuwelera ya silinda ya re P kanandi ŵakukhizga katundu.

Kupanikizgika-kulaŵilira ntchito yakujara chipewa

Ici cingaŵa cakumanyikwa na waliyose. Nga umo vikulongosoreka pa cithuzithuzi pakwamba, mitundu yinyake yili na nchito ya kukhoma chipewa. Pamanyuma pakuti liwiro la Pneumatic cylinder lasinthika makora, mu malo ghanyake agho ghakukhumbikwa liwiro likuru, kuti kugwedezeka kuleke kusintha pakujumpha kwa nyengo panji kukhwaskika mwangozi na ŵanchito ŵanyake, mtundu uwu wa vavu yakulongozgera liwiro ukugwiriskirika ncito. Mbunenesko kuti mtengo wake ngwakukwana. Mu nyengo zinandi, ŵambura kumanyikwa ŵangagwiliskirika nchito.

Kusankha kwa diamita ya vavu ya throttle

Ulusi wa throttle valve ukusankhika mwakuyana na silinda, apo chitoliro cha vavu yakulongozgera liwiro chikusankhika mwakuyana na silinda la Pneumatic. Kanandi, diameters zakuzomerezgeka zikuperekeka pakwamba pa buku la mtundu, ilo lingawoneka kuti lisankhike. Lekani kusankha chitoliro cha mphepo icho chili na msinkhu uchoko chomene, icho chingapangiska kuti silinda ya Pneumatic yileke kugwira ntchito panji kuŵa na chinthu chakukhwaŵa.

Pamwamba pa fundo yakugwira ntchito ya mavavu gha silinda la Pneumatic, mikhaliro, na kusankha kwa mavavu gha silinda la Pneumatic. Kuti mumanye vinandi vyakukhwaskana na nkhani iyi, lutani kuhttps://www..
