Istili - ntoni na? Iintlobo kunye nemibhobho nenjongo

Istili - ntoni na? Eli gama lithi ezininzi ezingaqhelekanga ezininzi zabantu. Kakade ke, ukuze kwandiswe sijonge lo mbuzo, kufuneka ukuba babe nolwazi olukhethekileyo ukuba okungenani kwisikolo yobugcisa. Noko ke, le ndoda eqhelekileyo ezichaphazela eneenkcukacha abanjalo kufuneka, ke ngoko, mabangapheleli ngokwethu iingqiqo jikelele.

Eli nqaku liza kuvavanywa kunye le mibuzo ilandelayo:

1. Istili - ntoni na?
2. yayisebenzisa Uphi na?
3. Yintoni injongo?
4. Ziziphi iintlobo zezinto zenzeke?

Istili: amanqaku abalulekileyo

• Used casings for amaqula kakhulu ukuqinisekisa ubomi kwenzeka lobume hydraulic.
• Xa ngokukhetha izinto eziyimfuneko ukuze ingqalelo into yokuba naziphi na iziphene okanye iziphene evela kuya kuba nzima ukususa.
• ekukhetheni okubi ye elements istili kungakhokelela ekubeni into yokuba amanzi ngokuzala iqula uya kuba yanto emva kweminyaka embalwa.

Ukubekwa istili

Ukuze siqonde istili - iyintoni kwaye ones zisetyenziselwa izinto kakuhle, kufuneka uqonde ngokucacileyo injongo yalo msebenzi.

Ivela kule nto kwaye uyonyulwa kunye iimpawu yokusebenza efanelekileyo.

Cinga imisebenzi ekufuneka yenziwe yi lombhobho ololo hlobo:

• Owona msebenzi istili - ukuqinisekisa ukuthembeka kweendonga yequla lonke ixesha lokusebenza. Istili kufuneka ube amandla elungileyo ukuze sixhathise naluphi na utshintsho lomhlaba. Xa ubomi ezikhethiweyo kakuhle izinto womthombo kufuneka ube neminyaka engaphezu kwama-50 ngezizathu nawuphi na xaka.
• Injongo yesibini ephambili, nto kubalulekile ukunikela ingqalelo phambi kokuba izixhobo ukhetha (ingakumbi kwimihlaba kunye nenani eliphezulu angenwa lulwelo Asinakusebenziseka ukulungiselela iinjongo okusela), - kukuqinisekisa yengxinano eso sakhiwo. Istili threaded kufuneka ukuthintela ukungena kwi ngasequleni Leucaspius kunye namanzi ukusuka kwenye lawo. Zonke notsalo ezenziwe ukusuka akhwifa ethile efanelekileyo iimpawu zabo ngokwasemzimbeni imichiza.

Ngoko ke, sikhetha nelembande, kuyimfuneko ukuba banikele ingqalelo kule ndlela wokujoyina. Kukhethwa inikwa zonxibelelwano azinamsonto.

Iintlobo imibhobho esetyenziselwa istili kakuhle

Istili - yintoni na anganika iinkcukacha zayo nayiphi specialist. Ukuba amagama alula, oko kuyinto material nokuqinisa eqhelekileyo. Nangona kunjalo, kunyanzelekile ukuba akhethe ekunene, njengoko umgangatho iya kuxhomekeka kumsebenzi kwinkqubo yonke. Ukuziqhelisa, iintlobo ezahlukeneyo sombhobho istili ukwenza imithombo amanzi anzongonzongo ezahlukeneyo. Abo eziphambili ziquka isinyithi, iplastiki kunye asbestos lwesamente.

Uluhlu ezi mveliso zenziwe ngokungqinelana GOST 632-80.

imibhobho metal

istili ilungiselelo amaqula zinokusetyenziswa izakhiwo isanti kunye lekalika (amaqula nokususa). Olu hlobo luphawulwa ngamandla elungileyo nokuzabalazela na ntshikilelo ngoomatshini. Le ngobubanzi ye istili ngentsimbi isusela ukusuka 114 ukuya 508 mm. Xa Ebubanzini bodonga na omise ezintlanu ukuya kwezintandathu izixhobo iya kuthatha ubuncinane iminyaka engama-50. Ukongeza, kuyimfuneko ukuba ukwamkela into yokuba xa kwimeko etyekezwa wequla kukho ithuba usebenzisa isixhobo sokugrumba ukubuyisela yokusebenza yayo, kwaye iyafumaneka ukuba ezinye iindidi ze imibhobho.

Kodwa steel abamnyama kwaye eziliqela kuneengxaki ebalulekileyo. Ngokuyintloko, loluthando umxhelo ngenxa umhlwa, nto leyo ekhokelela yimbonakalo umhlwa emanzini (nangona le ngxaki isonjululwe okucoca mihla). Le yesibini kwaye mhlawumbi ebaluleke kakhulu - iindleko eziphezulu kwemibhobho zamafu-sibiyelweyo. Kungenxa yoko le nto umda iphambili istili sobhedu ngokuxhobisa equleni izixhobo zokusebenza ezibalulekileyo. Kuba ukugrumba amaqula kuyaphi esantini kuyacetyiswa ukuba kusetyenziswe izinto zitshiphu.

Imibhobho asbestos-isamente

Enye impahla yemveli esetyenziselwa istili amaqula, - asbestos. Inzuzo ephambili yemibhobho ezinjalo - iindleko phantsi, ukumelana ukuhlasela iikhemikhali yaye korrozirovaniyu bume silwe, neminye imiqondiso baphelelwe iimveliso zentsimbi. Luncedo - brittleness eliphezulu nto leyo yenza kube yimfuneko ukuba andise Ebubanzini bodonga, kwaye oku kuthetha ukuba kufuneka ukugrumba kakuhle ukuba ubukhulu enkulu. Ukongeza, le nto ayikwazi kusetyenziswa xa kusakhiwa imihlathi lokucoca ulwelo.

Eyona Isicelo kwalo istili - amaqula nokususa (in lekalika), ubunzulu hayi ngaphezulu kwe ngekhulu leemitha.

imibhobho yeplastiki

Kwiminyaka yakutshanje baba istili kuthandwa yeplastiki ukuba amaqula kunye ngomsonto kubavelisi ogama zinika ubomi ngenkonzo ebalulekileyo. Kakade ke, malunga nokuqina kusenzima ukugweba, kodwa into yokuba iimveliso ezinjalo yexabiso eliphantsi, non-bako, iikhemikhali cala, kunokuthiwa ngokuqiniseka.

Ngokusisiseko, ukuze enze izinto istili kusetyenziswa PVC (UPVC), ezinepolypropylene okanye iHDPE. Uyilo kwezi kwemibhobho inophawu share lutho, kodwa ziyaxhonywa enkosi unxulumano azinamsonto nje.

Le Ububi obukhulu luvukelo ihlwempu ukuba umonakalo, loo una re-eweva yi kunokuba yingxaki, yaye ngokufuthi nje akunakwenzeka.

Isicelo ezingundoqo imibhobho ezinjalo - amaqula phezu kwentlabathi, ubunzulu akukho kweemitha ngaphezulu kwe 50-60, ukongeza, kuzo ezifanele ngokucacileyo ukufakelwa iikholam lokucoca ulwelo.

Ukuze isigqibo ezikhethiweyo ukuba istili amaqula eziphathekayo akunconywa, oko afanele ukukwenza ingcaphephe ngubani na ukuhlola zonke iimpawu zomhlaba kwi indawo yokombiwa. Khumbula ukuba, nangona uluhlu kakhulu zemathiriyeli kule njongo, nayiphi na impazamo kwisigaba kuyilo iza kunciphisa ubomi ukusebenza le kakuhle.
