Vuto lamagetsi lamagetsi limakuphunzitsani kusankha kolondola kwa valavu yamagetsi ndi valavu ya pneumatic komanso ubwino ndi kuipa kwa mitundu iwiri ya mavavu.

Zotsatira za sikelo

Kaya valavu ya solenoid kapena valavu yamagetsi, kukula sikudzangopangitsa kuti valavu iwonongeke, yoopsa ngakhale imakhudza ntchito yachibadwa ya valve, momwe mungathetsere mphamvu ya sikelo, yakhala yodetsa nkhawa kwambiri pamakampani.

Kugwira ntchito kwa valve ndi kolakwika

Ndondomeko ya valve ya Solenoid yophatikizapo kukula kwake ndi yotakata kwambiri, koma chifukwa mapangidwe a actuator ndi kugwiritsa ntchito zipangizo zodzaza chifukwa cha kusagwira bwino ntchito kwa valve yolamulira akhoza kufotokozedwa mwachidule malamulo ake.

Kukhalapo kwa madera akufa munjirayi kumapangitsa kuti kusinthaku kuchoke pa malo oyamba. Chifukwa chake zotulutsa za wowongolera ziyenera kukulitsidwa mokwanira kuti zigonjetse gawo lakufa kuti izi zichitike.

Zinthu zazikulu zomwe zimakhudza gawo lakufa:

① Kugwedezeka, kugwedezeka, kugwedezeka kwa valve shaft, amplifier zone akufa. Ma valve owongolera amakhudzidwa ndi kukangana m'njira zosiyanasiyana. Ma valve ozungulira, mwachitsanzo, amakhudzidwa ndi kukangana komwe kumachitika chifukwa cha kuchuluka kwa mipando yayikulu, choncho dziwani izi mukamagwiritsa ntchito. Kwa zisindikizo zina, komabe, katundu wapampando wapamwamba ndi wofunikira kuti akwaniritse kalasi yosindikizira. Chotsatira chake, valavuyi imapangidwa molakwika ndipo imayambitsa mosavuta malo akuluakulu akufa, omwe ali ndi zotsatira zoonekeratu komanso zotsimikizika pamlingo wopatuka.

② Kung'ambika. Kuvala mavavu sikungapeweke pakugwiritsa ntchito bwino, koma kuvala kwa wosanjikiza wothira ndikovuta, malinga ndi umboni woyesera, valavu yozungulira yopaka mafuta pokhapokha mazana ambiri obadwanso mwatsopano, wosanjikiza wothira mafuta sangathe kugwiritsidwa ntchito. Kuonjezera apo, katundu wokakamiza angapangitsenso kuvala zisindikizo, zomwe ndizofunikira kwambiri pakukula kukangana. Chotsatira chake ndi valve yowononga yowononga

(3) Kuthamanga kwapang'onopang'ono ndiko gwero lalikulu la kugwedezeka kwa valve, kugwiritsa ntchito kulongedza kosiyana, zomwe zimapangitsa kusiyana kwakukulu pakulimbana.

(4) Mitundu yosiyanasiyana ya ma actuators imakhudzanso mphamvu yakukangana. Nthawi zambiri, opanga mafilimu a kasupe ndi abwino kuposa opanga ma piston.

Phunzitsani kusankha kolondola kwa valavu yamagetsi ndi valavu ya pneumatic ndi ubwino ndi kuipa kwa mitundu iwiri ya mavavu Vavu yamagetsi yoyendetsedwa ndi magetsi, muzofunikira za kuphulika kwa chochitikacho sikoyenera, monga malo oyandikana nawo omwe ali ndi chiwerengero chachikulu chosavuta. mpweya wopaka utoto, mutha kudalira pneumatic. Nthawi yakuyankha kwa pneumatic ndi yocheperako kuposa magetsi, osati yolondola ngati magetsi, valavu ya pneumatic ndi mphamvu ya pneumatic. Valavu yamagetsi imasandulika kukhala mphamvu yamagetsi monga mphamvu, mphamvu ya valve yamagetsi ndi yapamwamba kuposa ya valve ya pneumatic, chitetezo ndi kudalirika sikuli kolimba ngati valavu ya pneumatic, kukonza sikuli kosavuta monga valavu ya pneumatic. , mphamvuyo siili yolimba ngati valve ya pneumatic.

1. Vavu yamagetsi imagwiritsa ntchito mota ngati mphamvu, ndipo valavu ya pneumatic imagwiritsa ntchito mpweya woponderezedwa ngati mphamvu.

1. Ubwino wa valavu yamagetsi: Kuchita bwino pamadzi apakatikati ndi gasi wamkulu m'mimba mwake, osakhudzidwa ndi nyengo. Osakhudzidwa ndi kuthamanga kwa mpweya.

Zoipa: mtengo wokwera, osati wabwino m'malo achinyezi.

2. Ubwino wa valavu ya pneumatic: Kuchita bwino pamadzi apakati apakati ndi ang'onoang'ono, otsika mtengo komanso kukonza kosavuta.

Zoipa: Zomwe zimakhudzidwa ndi kusinthasintha kwa mpweya, zimakhala zosavuta kukhudzidwa ndi kuthamanga kwa mpweya ndi madzi a mpweya kumpoto kwa nyengo yozizira, zomwe zimapangitsa kuti azizizira komanso osachitapo kanthu pa dipatimenti yopatsirana.

Momwe mungasankhire valavu yamagetsi ndi valavu ya pneumatic molondola

Awiri, ambiri pneumatic ndi mofulumira kuposa magetsi, magetsi ndi wapawiri ntchito tochi. Ndipo pneumatic to hand, gasi wogwiritsa ntchito pawiri mtengo ndiwokwera kwambiri.

Chachitatu, valavu yamagetsi imagwiritsidwa ntchito m'malo ena akuluakulu awiri, chifukwa mpweya ndi wovuta kuchita, koma valavu yamagetsi siili yosokoneza ngati pneumatic, liwiro la kusintha ndilochedwa, actuator idzakhazikika kwa nthawi yaitali. Kusintha kwa valve ya pneumatic mwachangu, molondola kwambiri, koma osafunikira chipwirikiti cha mpweya.

Chachinayi, valavu yamagetsi ikuchita pang'onopang'ono valavu yamagetsi imatha kuchita kuphulika-umboni chizindikiro si ambiri; Mavavu a pneumatic ndi othamanga, osaphulika mtengo kuposa pansi pamagetsi (chinyumba cha pneumatic valve chokhala ndi zida zotani, chokhala ndi zida zazikulu zamtundu chimakhala chokwera mtengo kuposa valavu yamagetsi).

Ma valve omwe amalumikizana nawo ndi magetsi. Chifukwa chiyani?

1, malinga ndi nyengo yam'deralo, ngati nyengo ili yonyowa, valavu ya pneumatic singagwiritsidwe ntchito, chifukwa mpweya uli ndi madzi.

2, valavu yamagetsi imatha kuzindikiranso ntchito yolumikizirana popanda kuwonjezereka kogwiritsa ntchito, kulowetsedwa kwa pneumatic kumawonjezera valavu yosungira, kuonjezera mtengo.

Ubwino ndi kuipa kwa valavu yamagetsi ndi valavu ya pneumatic:

Pazifukwa ziti muyenera kugwiritsa ntchito valavu magetsi popanda pneumatic, pamene kufunika ntchito pneumatic popanda valavu magetsi, pakati pawo ubwino ndi kuipa, mtengo. Kutalika kwa valavu ya pneumatic ndi yayikulu kuposa valavu yamagetsi, liwiro la valavu ya pneumatic lingasinthidwe, mawonekedwe osavuta, osavuta kusamalira, pochitapo kanthu chifukwa cha mawonekedwe amafuta omwewo, osavuta kuonongeka ndi jamming, koma ayenera kukhala ndi gwero la mpweya, ndipo dongosolo lake lolamulira ndilovuta kwambiri kuposa valve yamagetsi.

Valve yamagetsi imayendetsedwa ndi magetsi, omwe si oyenera nthawi ya zofunikira za kuphulika. Pamene mipweya yambiri yotayidwa mosavuta imamwazikana pafupi ndi chilengedwe, imatha kudalira pneumatic. Nthawi yakuyankha kwa pneumatic ndi yocheperako kuposa magetsi, osati yolondola ngati magetsi, valavu ya pneumatic ndi mphamvu ya pneumatic. Valavu yamagetsi imasandulika kukhala mphamvu yamagetsi monga mphamvu, mphamvu ya valve yamagetsi ndi yapamwamba kuposa ya valve ya pneumatic, chitetezo ndi kudalirika sikuli kolimba ngati valavu ya pneumatic, kukonza sikuli kosavuta monga valavu ya pneumatic. , mphamvuyo siili yolimba ngati valve ya pneumatic.

Kuwongolera kwa valve ya pneumatic ndizovuta kwambiri kuposa za valve yamagetsi. Ndipo mtengo wake ndi wokwera mtengo kwambiri, ngati umakhudza kulamulira basi, m'pofunika kuwonjezera valavu ya electromagnetic reversing valve, ndipo mphamvu ya electromagnetic reversing valve imakhudza mwachindunji valavu ya pneumatic. Ndimakonda chipinda choyamba.

Mavavu amagetsi atha kugwiritsidwa ntchito bola magetsi alipo. M'mafakitale ena, zida zambiri ndi zida zimagwiritsa ntchito mpweya woponderezedwa. Pachifukwa ichi, ma valve a pneumatic angagwiritsidwe ntchito, chifukwa amapezeka mosavuta. Yankho lake ndi lachangu, lotetezeka komanso lodalirika, mafakitale ambiri omwe ali ndi zofunikira zowongolera kwambiri amapangidwira zinthu zowongolera zida za pneumatic kuti akhazikitse ma air station oponderezedwa. Zamagetsi zikutanthauza magetsi. Valve ya pneumatic ndi yabwino kwambiri kuposa valavu yamagetsi, koma gwero la mpweya ndiloipa kwambiri kuti valavu yamagetsi imagwiritsidwa ntchito m'malo mwa mpweya.
