Lub siab ntsuas pneumatic hose yog hloov tau, hloov ntaub ntawv tam sim no uas tawm tsam UV hluav taws xob thiab lwm yam sab nraud. Lub hom phiaj yog kom muab cov kwj ntws los ntawm qhov tshuab pa mus rau lub cuab yeej. Lawv siv los ua cov phom txau phom, tshuab grinders, ntsia hlau, thiab lwm yam. Pneumatic cov tshuab raj siab siab siv rau hauv ntau qhov kev lag luam, thoob plaws vim lawv cov kev coj ua thiab cov haujlwm ua haujlwm zoo.
Thaj chaw ntawm kev siv
Qhov tshwj xeeb ntawm daim ntawv thov yog nyob ntawm cov yam ntxwv ntawm cov hlab thiab cov khoom siv los ntawm qhov uas nws tau ua. Polyamide siv dav hauv kev lag luam lub cev muaj zog thiab tsheb, kev tsim cov tshuab vuam, cov cuab yeej siv rau lub chaw soj nstuam, thiab ntsuas cov twj paj nruag. Lawv yog qhov tseem ceeb nyob rau hauv nruab nrab lubrication thiab hydraulic system.
Cov qauv polyurethane muaj ntau dua tiv taus cov tshuab thiab kev nyuaj siab. Lawv siv rau hauv cov kev lag luam nrog cov nra hnyav. Hauv tshwj xeeb, cov cav tsheb thiab cov tshuab siv nrog polyurethane hoses; lawv tau siv los tsim kev sib txuas hauv kev ntsuas thiab tswj cov thev naus laus zis.
Polyethylene yog cov ntau tshaj plaws, muaj tus cwj pwm siv thoob ntiaj teb. Lawv feem ntau siv los ua kom tiav cov cuab yeej pneumatic: kev lag luam thiab tsev neeg.
Cov sib txawv hauv cov khoom siv
Cov qauv hloov pauv ntawm pneumatic hose yog vim kev siv cov ntaub ntawv tshwj xeeb elastic khoom. Raws li cov khoom siv, cov khoom sib txawv hauv:
- polyvinyl tshuaj dawb. Ua los ntawm PVC. Xws li cov qauv no yog tus yam ntxwv zoo, muaj kev ywj pheej zoo, tiv taus kev sib ntswg, kinking, UV;
- polyamide. Cov yam ntxwv tseem ceeb ntawm cov tub xws li lub teeb yuag, hloov tau yooj yim, tsis kam mus rau qhov siab, ntau yam kev ua haujlwm kub;
- polyurethane. Lawv tau cim los ntawm cov cim hauv qab no: kev ua haujlwm siab elasticity, tsis kam tiv thaiv kev puas tsuaj, puas. Rov khaws cov kev hloov pauv yooj yim ntawm kev teeb tsa ntawm qhov kub qis;
- teflon. Xws li cov raj tau koom nrog qeb ntawm cov khoom siv tiv thaiv tshav kub, tiv taus kev tshaj tawm kev tawm tsam, UV, ozone;
- roj hmab nrog cov txheej txheem txhawb thiab. Cov tshuab pneumatic no muaj qhov tshwj xeeb txhawb uas muab cov khoom ntxiv dag zog.
Nyob ntawm seb hom raj thiab hom ntawm cov khoom siv los ntawm qhov lawv tau ua, qhov ntsuas thiab tsim cov khoom sib txawv.
Nuances ntawm kev xaiv
Ua ntej tshaj plaws, koj yuav tsum them sai sai rau hom pneumatic hose thiab nws cov yam ntxwv kev. Hauv qhov tshwj xeeb, cov khoom siv cuam tshuam rau kev khiav hauj lwm kub. Yog li, polyurethane cua hoses muaj peev xwm tswj tau haujlwm ntawm -40 - +60 degrees. Qhov ntsuas ua haujlwm siab yog lub luag haujlwm rau kev ua haujlwm ntawm cov khoom ntawm qee qhov ntsuas ntawm kev ntsuas ntawm qhov nruab nrab.
Tshaj dhau cov lus pom zoo ua tsis zoo yuav ua rau lub raj xa dej. Qhov nruab nrab, qhov kev tso cai pom tau zoo tsis ntau tshaj 15 atm.
Lwm qhov kev ntxiv tshuab suav nrog qhov tsim hose. Lawv ncaj thiab kauv. Cov tom kawg tau nrawm dua, txuag thaj chaw zoo, thiab yooj yim dua rau kev ua haujlwm nrog. Nws tsim nyog them sai sai rau cov diameters: sab nraud thiab sab hauv. Daim duab no txiav txim siab qhov nkag ntawm lub raj. Qhov kev pom zoo tso cai sab hauv taub rau kev ua haujlwm zoo ntawm cov cuab yeej huab cua yog> 5 hli. Ntev yog lwm tus yam ntxwv tseem ceeb ntawm hoses. Lawv khwv yees li ntawm 5 txog 20 m. Txawm li cas los xij, koj yuav tsum tsis txhob xaiv cov kav dej ntev dhau lawm, vim qhov no yuav txo qhov tsim tau ntawm cov khoom lag luam nruab nrab. Kho qhov ntev dim qhov ntev kom txog qhov xau poob.
Txawv thiab lwm qhov sib txawv uas yuav tsum qhia meej thaum xaiv yog hom kev txuas ntawm hoses nrog cov cuab yeej pneumatic: bayonet thiab nrawm. Qhov thib ob tseem muaj lub npe hu ua cov txuas lus ceev nrawm. Lawv yooj yim dua rau siv, lawv niaj hnub nyob rau hauv kev sib piv nrog bayonet mount.
Feem ntau, thaum xaiv lub tshuab pneumatic, koj yuav tsum tau coj los ntawm cov yam ntxwv kev coj ua thiab kev pom zoo ntawm cov tuam txhab. Hauv kev pom ntawm qhov no, nws yog qhov yuav tsum tau yuav cov khoom zoo li no hauv khw muag khoom tshwj xeeb lossis hauv cov vev xaib.
