Hauzive nzira yekusarudza blast nozzle? Kutevera matanho mana, zviri nyore!

--Matanho mana anokuudza maitiro ekusarudza akakodzera kuputika nozzles

Sandblasting nozzles dzakagadzirwa mumhando dzakasiyana dzine hukuru hwakasiyana uye maumbirwo kubva kune akasiyana zvinhu. Kusarudza iyo chaiyo sandblast nozzle kune yega yega application ingori nyaya yekunzwisisa zvinosiyana zvinokanganisa kuchenesa kuita uye mutengo webasa. Kana iwe usingazive nzira yekuzvisarudzira muromo wakakodzera, tevera matanho mana senge pazasi.

1. Sarudza iyo Nozzle Bore Size

Pakusarudza muromo, inotanga neyakoair compressor. Kana iwe uchinge wanzwisisa kuti saizi yecompressor yako inokanganisa sei kugadzira hunyanzvi, ipapo iwe uchazoda kutarisanozzle size. Sarudza muromo une diki diki yebore uye unenge uchisiya imwe inoputika simba patafura. Yakanyanya kubhowa uye iwe uchashaya kudzvanywa kwekuputika zvine pundutso.

Tafura iri pazasi inoratidza kuwirirana pakati pehuwandu hwemhepo, saizi yenozzle, uye kudzvanywa kwenozzle uye inowanzo shandiswa muindasitiri kusarudza saizi yenozzle. Yayo chaiyo bhenefiti ndeyekusarudza yakaringana nozzle saizi yekumanikidza yenozzle inodiwa kuita basa.

2. Sarudza iyo Nozzle Shape

Inotevera ndiyochimiro chemuromo. Nozzles inouya mumhando mbiri dzakakosha:Straight boreuyeVenturi, ine akati wandei akasiyana eVenturi nozzles.

Straight Bore nozzles(Chiverengo 1) gadzira chimiro chakasimba chekuputika kwenzvimbo yekuputika kana kuputika kwekabati basa. Izvi zvakanakira mabasa madiki senge zvikamu zvekuchenesa, weld seam shaping, kuchenesa handrails, nhanho, grillwork, kana dombo rekuveza nezvimwe zvinhu.

Venturi yakabereka mhino(Chiverengo 2 ne3) gadzira pateni yekuputika kwakafara uye kuwedzera abrasive velocity neinosvika 100% pakumanikidzwa kwakapihwa.

Venturi nozzles ndiyo yakanakisa sarudzo yekukura kukuru kana ichiputika nzvimbo dzakakura. Kaviri venturi uye yakafara huro nozzles akakwidziridzwa shanduro dzerefu venturi style nozzle.

Thedouble venturimanyorerwo (Chiverengo 4) anogona kurangarirwa semapfumbu maviri akatevedzana ane mukaha nemakomba pakati kuti abvumire kupinzwa kwemhepo muchikamu chepasi pemvura. Mugumo wekubuda nawo wakapamhama kupfuura muromo wakajairwa. Zvose zvinogadziriswa zvinogadzirwa kuti zviwedzere saizi ye blast pattern uye kuderedza kurasikirwa kweabrasive velocity.

Huro dzakafara nozzles(Nhamba 5) inoratidzira huro hombe yekupinda uye bhomba rakakura rekubuda kunze. Kana ichifananidzwa nehosi yakaenzana saizi vanogona kupa kuwedzera kwe15% mukubudirira pamusoro pemanozzles ane huro diki. Iri zano rakanaka zvakare kuve nemakona nozzles aripo kune dzakasimba nzvimbo seyemwenga lattice, kuseri kwemaflange, kana mukati mepombi. Vazhinji vashandisi vanoparadza mabrasives uye nguva yakamirira ricochet kuti basa riitwe. Nguva diki inotora kuti uchinje kune anangle nozzlenguva dzose inonaya nokukurumidza, uye nguva yose pabasa inoderedzwa.

3. Sarudza iyo Nozzle Material

Paunenge uchinge waona iyo nozzle size uye chimiro, iwe unozoda kufunga nezvezvinhuiyo nozzle liner inogadzirwa. Zvinhu zvitatu zvakakosha pakusarudza yakanakira nozzle yakaboora zvinhu ndeyekusimba, kukanganisa kupikisa, uye mutengo.

Kusarudzwa kwezvinhu zveNozzle zvinoenderana neabrasive yaunosarudza, kangani kaunoputika, saizi yebasa, uye kuoma kwenzvimbo yebasa. Heano maitiro akajairwa ekushandisa kune akasiyana zvinhu.

Tungsten carbide nozzles:Inogona kupa hupenyu hurefu uye hupfumi apo kubata kwakashata hakugone kudziviswa. Inokodzera kuputika slag, girazi, uye mineral abrasives.

Silicon carbidenozzles:Impact inoshingirira uye yakasimba senge tungsten carbide, asi ingangoita chikamu chimwe chete muzvitatu huremu hwetungsten carbide nozzles. Sarudzo yakanakisa kana vashandisi vari pabasa kwenguva yakareba uye vachisarudza lightweight nozzle.

Boron carbide nozzles:Yakanyanya kuoma uye yakasimba, asi brittle. Boron carbide yakanakira mabrasives ane hukasha akadai sealuminium oxide uye akasarudzwa mamineral aggregates kana kubata kwakashata kuchigona kudzivirirwa. Boron carbide inowanzopfekedza tungsten carbide kashanu kusvika kagumi uye silicon carbide kaviri kana katatu panoshandiswa mabrasives ane hukasha. Mutengo ndiwo zvakare wepamusoro pakati pavo.

4. Sarudza Thread uye Jacket

Pakupedzisira, iwe unofanirwa kusarudza zvinhu zvejasi kudzivirira bhomba. Iwe unofanirwawo kufunga kuti ndeipi mhando yeshinda inonyatso kuenderana nezvido zvako zvekuputira jecha: shinda yakakora kana shinda yakakasharara (contractor).

1) Nozzle Jacket

Aluminium Jacket:Aluminium mabhachi anopa yakanyanya mwero yedziviriro kubva mukukanganisa kukuvara muhuremu.

Simbi Jaketi:Mabhachi esimbi anopa yakanyanya mwero yedziviriro kubva mukukanganisa kukuvara muheavyweight.

Rubber Jacket:Rubber bhachi is Lightweight ichiri kupa kuchengetedzwa kwemhedzisiro.

2) Thread Type

Yakakora (Contractor) Thread

Indasitiri-yakajairwa shinda pa 4½ shinda pa inch (TPI) (114mm), chimiro ichi chinoderedza zvakanyanya mukana wekuchinjika-kuchinjika uye chiri nyore kuisa.

Fine Thread(NPSM Thread)

Iyo National Standard Yemahara-Yakakwana Yakatwasuka Mechanical Pipe Thread (NPSM) ndiyo Indasitiri mwero wakatwasuka shinda inoshandiswa zvakanyanya muNorth America.

PFUNGWA DZEKUPEDZISIRA

Mhepo mikuru uye mahombe mahombe anotungamira kumitengo mikuru yekugadzira, asi chimiro chebhoo remuromo chinotaridza kukwidziridzwa kwezvikamu uye saizi yemhando yekuputika.

Mune zvese, hapana yakanakisa muromo, kiyi yakakosha ndeyekutsvaga akanyanya kukodzera mabhomba ekushandisa kwako.
