Chisindikizo zisindikizo kutulutsa: malongosoledwe a mitundu ndi ndemanga

Mafakitale pa ntchito payipi, zosiyanasiyana mitundu ya mapampu amatipeza uka imfa madzi. Kupewa milandu ndi zisindikizo ambiri, mmodzi amene ayankhidwa mwatsatanetsatane m'nkhani ino.

Chisindikizo zisindikizo kutulutsa

mapampu Modern okonzeka ndi chiwerengero chachikulu cha zinthu. Mu nkhani iyi, kulunjika ntchito chofunika kuganizira uziyenda zachilendo ndipo yosalala mankhwala wonse. Anatsekera zopangitsa mapampu maganizo a kuphweka ntchito yomanga ake ndi chomasuka ntchito ntchito kwambiri zambiri kuposa zipangizo zina wosindikiza.

amafuna opaleshoni

Impeller mitundu yonse ya ikukoka zida ntchito kuthokoza galimoto ndi. Nthawi zambiri ndi magetsi. Kudzera lumikiza makina opatsirana mphamvu kuchokera injini kutsinde kwa impeller, amene amakhazikitsa mu filimu. kutsinde palokha ndi kunja zida nyumba, kupanga mthunzi leaky. Chifukwa imfa mosalephera a madzimadzi ntchito.

Ngati inu ntchito chisindikizo kubisa mabokosi a mapampu, ndi kutayikira wa madzi amawapopa zikhoza kupewedwa. Amagwiritsa ntchito njira zamakono zotsatirazi:

1. Ramming (England) chisindikizo. Bwaloli mphete zakuthupi fibrous.

2. Lip. Chifukwa chisindikizo chotero, zipangizo kusintha kuti akhoza analimbitsa kuonjezera stiffness. Ntchito ogwiritsa mu zida ikukoka ndi rotational liwiro otsika.

3. Mawotchi. Amakhala ndi mphete ziwiri kwambiri spaced kwa mnzake m'dzenjewo. Mmodzi imazungulira ndi kutsinde, ndi ena amakhalabe ima kwathunthu.

4. Kudula. Dzina chachiwiri - kukhotakhota. Amaona kwambiri masiku ano malingaliro odalirika chisindikizo. Kuperekedwa monga mphete ku aloyi zofewa. Izo ntchito mu mapampu multistage, pamene ntchito ya umisiri ena akhoza kwambiri bwanji Mwachangu lapansi.

Komanso, pali zipangizo zimene popanda zisindikizo, monga mapampu ndi lumikiza maginito ndi ozungulira yonyowa.

Kufotokozera Zisindikizo, mawotchi

zipangizo Slotted zambiri ntchito kupereka chisindikizo cha mapampu submersible. Iwo sali pansi amafuna wapadera kutayikira madzimadzi. Apa n'chofunikira chachikulu nthawi ya opaleshoni.

Anatsekera zopangitsa mapampu anaonekera pafupifupi imodzi ndi zida wokha ikukoka madzi. Izi mphete wapadera zakuthupi fibrous, zomwe ndi zochokera stuffing ndi, choncho dzina lawo. wazolongedza ayenera wasambitsa kunyamulidwa ndi madzimadzi payipi. M'pofunika kuzirala ndi kondomu ya England lapansi. Chimodzimodzi wetting madzi ndi zinadzala ndi zomvetsa. mpope ola kumafuna imfa ya malita 1-15 madzi. Ngati gasket si uyu wasambitsa, nkhani wotaya phindu mofulumira "kuwotcha kunja."

M'pofunika zonse kukhala gaskets. Compressors ndi mapampu nthawi yomweyo simungathe kupita kuti, ndipo ndi imodzi mwa ubwino kwambiri kwa zisindikizo. Self ndi nthawi "Chikoka mmwamba" khafu.

Kusiyana Chitsanzo cha zisindikizo zipangizo mpope

Msika wamakono amapereka zosiyanasiyana zisindikizo kuti mapampu; zisindikizo wamba awa akuimira mitundu ikuluikulu iwiri:

1. Kubisa ndi m'mphepete anatsindika. Cholinga chachikulu - kupewa imfa ya madzi amawapopa.

2. Manja analimbitsa bellow ndi m'mphepete wina. Ntchito kuteteza pawiri kuchokera fumbi ndi uve. Komanso, musalole madzimadzi kusiya dongosolo kayendedwe.

Ngati tikulingalira akafuna kupanga tingasiyanitsire zisindikizo:

• ndi m'mphepete kuumbidwa;

• ndi m'mphepete chimene ndi Machining lomaliza.

Malinga mtundu wa mphira ndi cuffs amenewa:

1. Kuchokera pa mphira nitrile. Zamgululi zopangidwa kuchokera 1, 2 ndi 3 cha mphira kalasi. Yodziwika ndi mkulu ndi zoipa pakhomo opaleshoni kutentha (-30, -45, ndipo -60 ° C motero).

2. Pamaziko a mphira fluoro. Zopangira - magulu mphira 1 ndi 2. Pamene ikukoka kufala mafuta kapena mchere kupirira kutentha kwa 170 ° C.

3. Wa mphira silikoni. Mu kupanga matayala ntchito basi gulu lina. M'munsi malire a wazolongedza ntchito kutentha -55 ° C.

Monga ulamuliro, cuffs zamakono ndi akasupe. Iwo ali oyenera zisindikizo pa migodi ya diameters osiyana.

Kasupe akhoza aziwapatsa mosiyana England ngati akuyembekezeka ntchito ndi kutsinde 20 mamilimita kapena kuposa 120 mm.

Stuffing bokosi: ntchito makhalidwe amene mapampu ntchito bwino

Monga ulamuliro, ndi cuffs zimasiyana ndi zisindikizo zina kusinthasintha ake, plasticity. Mkulu avale kukana ndi mwayi lalikulu la mankhwala. Negligible mphamvu pa kutsinde la lakamba zambiri za gawo ntchito.

makhalidwe Magwiridwe ndi mwachindunji amadalira kapangidwe ndi zikuchokera sealant, amene wakhala ntchito mu kupanga. Malinga yokhotakhota ndi opendekera (kudzera ndi kuphatikiza) ndi mmodzi gaskets multilayer (kunena za dongosolo pachimake). Malinga zikuchokera khafu ndi:

• asibesitosi ndipo sanali asibesitosi;

• zouma ndi impregnated (monga impregnation mafuta ntchito, graphite ndi osakaniza zomatira);

• pomwe unreinforced.

Zisindikizo ntchito wosindikiza mankhwala centrifugal, mapampu pisitoni ndi makina hayidiroliki. Padding ungagwiritsidwe ntchito zipangizo ikukoka plunger madzimadzi. Pamene khazikitsa mankhwala siyenera kuti mapampu England chisindikizo aphonya wina kuchuluka kwa madzi, anatchula pamwamba.

Graphite-ceramic zisindikizo

Ichi ndi chimodzi mwa mitundu ya cuffs kwa ikukoka zida. Ntchito mtundu chisindikizo kwathunthu kukusalani ingress ntchito madzimadzi akonzekeretse galimoto. Kodi zisindikizo ntchito ting'onoting'ono basi graphite-ceramic? mapampu madzi, zomwe kupsa chisindikizo makina, osati kwambiri. Childs, ntchito malire ndi njira pamwamba gawo.

moyo Service angafikire zaka 10. Iwo ayenera kutsatira machitidwe olondola okwerera ikukoka. Chintchito chachikulu panthawi ya zida:

1. Chosowa "youma pake." Izo kutiletsa kusunga mpope mu "pa" mode, ngati pali madzimadzi mu dongosolo.

2. Ndi bwino kupulumutsa mankhwala ambiri woyengeka. Pamaso zosafunika adzakhala kufupikitsa utumiki khafu.

3. Onetsetsani kuti asasiye boma kutentha.

Ubwino zisindikizo kwa chisindikizo mapampu madzi

Cuffs zida kutulutsa madzi zikuwoneka ngati lalikulu nsalu zingwe. Asibesitosi (thonje kapena bast) thonje kungakhale kulolerana zamkuwa kapena mkuwa waya. Zisindikizo kupopa madzi chisindikizo ali pakati zopangidwa patsogolo. Tepi kukula 5 0.5. Mwina ntchito m'malo masikito 4 mawaya patsogolo.

gaskets Akutsatira ndi chisindikizo madzi, monga ulamuliro, pa mbali suction. Koma n'zotheka ntchito, ndi ku mbali ina. kukula wazolongedza mwachindunji ndi m'mimba mwake wa m'dzenjewo. The pazipita angapo mphete chisindikizo - 5.

Kodi kusankha caul

Kusankha zisindikizo wochitidwa ndi chiwerengero cha makhalidwe. Mosakayikira, zofunika kwambiri ndi funso cha kudalirika. Pakati pa anthu, i zofunika ankaona mtengo. magawo zina akuganizira chipangizo:

• maola ntchito;

• imfa madzimadzi;

• alumali moyo;

• ndalama kuti mudzatuluka vuto la kukonza.

Komanso, kusankha zisindikizo kuti mapampu tidzakwatulidwa zamitundu m'Baibulo. Zikuphatikizapo diameters mkati ndi kunja, kutalika ndi makulidwe a gawo lapansi ndi.

kuchita ogula Kodi

Ambiri adziwa kwa England msonkhano mpope umodzi gawo. Nthawi zambiri amalembedwa ntchito zake zosiyanasiyana wazolongedza. Kugwiritsa ntchito zidindo si migodi mkulu-liwiro.

Iwo ananena kuti zisindikizo chisindikizo mapampu afewetsedwa silikoni ofotokoza zinaonetsedwa pa chionetserocho wamkulu matenthedwe bata.

Kusiyana ndi okhutira mkulu mpweya kwambiri kuchepetsa chiŵerengero kuwonjezeka ndi kuwonjezeka kutentha kwa madzimadzi. A aramid CHIKWANGWANI impregnated ndi PTFE mu wazolongedza alola ntchito mu chilengedwe zikuwononga kwa makampani mankhwala, zomera mphamvu ndi makampani pepala.
