Mtundu wa Valve-Cartridge Wothandizira


Tsatanetsatane

Ma valve oyenderana ndi oyendetsa ndege amapangidwa kuti aziwongolera katundu wopitilira muyeso. Valve yowunikira imalola kuyenda kwaulere

kuchokera ku valavu yolowera (doko 2) kupita ku katundu (doko 1) pomwe valavu yowongolera, yothandizidwa ndi woyendetsa ndege ikuyenda

kuchokera ku doko 1 kupita ku doko 2. Thandizo la woyendetsa pa doko 3 limachepetsa kukhazikitsidwa kwa valve yothandizira pa mlingo wotsimikiziridwa ndi

chiŵerengero cha woyendetsa.

NKHANI ZA NTCHITO

Ma valve olimbana nawo ayenera kukhazikitsidwa nthawi zosachepera 1.3 kuchuluka kwamphamvu komwe kumapangitsa kuti pakhale kuthamanga.

Sinthani zosintha mozungulira kuti muchepetse makonda ndikumasula katundu.

Kuyika kwanthawi zonse ndi kochepera 200 psi (14 bar).

Kubwerera kumbuyo pa doko 2 kumawonjezera kukhazikika kothandiza pa chiŵerengero cha 1 kuphatikizapo chiŵerengero cha oyendetsa ndege nthawi zambiri kumbuyo.

Kubwezeretsanso kumadutsa 85% ya kukakamiza kokhazikitsidwa pamene valavu imayikidwa. Zochunira zotsika kuposa kukakamiza kwa seti yokhazikika zitha kupangitsa kuti maperesenti oyambiranso achepe.

Makatiriji olimbana ndi dzuwa amatha kuyikidwa mwachindunji m'makina opangidwa ndi makina opangira magetsi kuti atetezedwe komanso kulimba kozungulira.

Pali mitundu iwiri ya ma valve omwe amawotcha. Gwiritsani ntchito cheke cha 25 psi (1,7 bar) pokhapokha ngati actuator cavitation ili ndi nkhawa.

Vavu iyi imagwiritsa ntchito ma orifices kutsitsa chiwongolero cha woyendetsa motero idutsa mpaka 40 in³/min./1000 psi (0,7 L/min./70 bar) pakati pa doko 2 ndi doko 3. Ichi ndikuganiziridwa m'mabwalo a kapolo-kapolo komanso kuyesa kutayikira kwa ma valve-cylinder.

Zonse za 3-port counterbalance, control load, and pilot-to-open check cartridges are transchanges kuthupi (i.e. njira yoyenda yofanana, chibowo chofanana cha kukula kwa chimango).

Zimaphatikizanso kalembedwe ka Dzuwa koyandama kuti muchepetse kuthekera komanga ziwalo zamkati chifukwa cha torque yoyika kwambiri komanso/kapena pabowo/katiriji.makina osiyanasiyana.

NTCHITO

Ma valve olumikizana ndi oyendetsa ndege amapangidwa kuti aziwongolera katundu wopitilira muyeso. Thevalavu yoyendera imalola kuyenda kwaulere kuchokera ku doko ② kupita ku doko ① pomwe woyendetsa molunjika, mothandizidwa ndi woyendetsazowongolera zowongolera zimayenda kuchokera kudoko ① kupita kudoko ② . Thandizo loyendetsa padoko ③ limatsitsakuyika bwino kwa valve yothandizira pamlingo wotsimikiziridwa ndi chiŵerengero cha woyendetsa.

MAWONEKEDWE

1. Ma valve otsutsana ayenera kukhazikitsidwa osachepera 1.3 nthawi zambiri zomwe zimapangidwirakupanikizika.
2. Kubwerera m'mbuyo pa doko ② kumawonjezera mpumulo wothandiza pa chiŵerengero cha 1 kuphatikiza woyendetsachiŵerengero nthawi ya backpressure.
3. Kubwezeretsanso kumapitirira 85% ya kupanikizika kokhazikika pamene valve imakhala yokhazikika. Kukhazikitsa pansikuposa kukakamizidwa kokhazikika kungayambitse kutsika kwa kuyambiranso.
4.Factory pressure setting inakhazikitsidwa pa 30cc / min (2 in3 / min).
 

Makhalidwe aukadaulo

Ntchito:

Valve yokwanira yokhala ndi kutsegulira kwa woyendetsa imagwiritsidwa ntchito kuwongolera kuchuluka kwa zinthu. Mafuta amayenda momasuka mbali imodzi kuchokera ku doko ② kupita ku doko ①; mafuta amayendetsedwa mwachindunji, ndipo wothandizira woyendetsa amasefukira kuchokera ku doko ① kupita ku doko ②. Port ③ ndiye doko lothandizira pakusefukira, ndipo kuyika bwino kwa ntchito kusefukira kumachepetsedwa malinga ndi kuchuluka kwa chiwongolero.

Khalidwe:

1.Kuthamanga kwapamwamba kwambiri kumakhala kosachepera 1.3 nthawi yochuluka yolemetsa.

2.Kuthamanga kumbuyo pa doko ② kumawonjezeredwa ku mtengo wamtengo wapatali wa valve yothandizira malinga ndi kuchuluka kwa "control ratio + 1", ndiko kuti, mtengo wowonjezera = (1 + control ratio) × mtengo wamtengo wapatali.

3.Pachikhazikitso chokhazikika, mtengo wotseka wotseka ndi waukulu kuposa 85% ya mtengo wamtengo wapatali; ngati ili yocheperapo kusiyana ndi chikhalidwe chokhazikika, chiwerengero cha kutsekera kwamtengo wapatali chimachepetsedwa moyenerera.

4.Kuyika kwa fakitale kumatanthawuza kupanikizika pamene valve yothandizira imatsegulidwa (kuthamanga ndi 30cc / min).
