Chii Chinonzi Grooved Fittings & Couplings?

Makochekedzo ane grooved ipombi dzinobviswa. Pakugadzirwa kwayo, mhete dzekusimbisa dzakakosha uye makochekedzo anotorwa. Hazvidi welding uye zvinogona kushandiswa kuisa mhando dzakasiyana dzemapombi. Zvakanakira zvekochekedzo dzakadaro zvinosanganisira kupatsanurwa kwadzo, pamwe nekuvimbika kwakanyanya, dzimwe nguva zvichipfuura zviratidzo zvakafanana zvemakochekedzo akasungirirwa uye akanamatwa.

Majoini emugero akagadzirwa kare kare. MuHondo Yenyika Yekutanga, aishandiswa kuisa mapaipi ane musanganiswa unobvira moto, uyo waishandiswa muzvipfura-moto. Kubva ipapo, ave achishandiswa mumabasa akasiyana-siyana ane rugare uko kwaidiwa kubatana kwakavimbika uye kwemhando yepamusoro.

Pakuisa pombi, kutarisisa kwakakosha kunopihwa pakubatanidza. Kugara kwenguva refu uye kuvimbika kwehurongwa, kugona kutsungirira mitoro yakakwira, uye nyore kwekugadzirisa kunotevera zvinoenderana nazvo. Kwenguva yakareba, kubatana kwetambo uye welding zvakashandiswa senzira huru dzekuisa. Nhasi, ma grooved couplings - ma clamps anobviswa ane sealing collar - ari kuwana mukurumbira. Muviri we clamp yakadaro wakagadzirwa ne ductile iron kana carbon steel, uye insert yakagadzirwa nezvinhu zverabha zvinodzivirira kupisa.

Zvichienderana nemitoro, ma coupling anogadzirwa nesimbi yakakandwa, simbi yekabhoni nezvimwe zvinhu zvakafanana. Coupling iyi ine zvikamu zviviri uye elastic polymer O-ring (cuff). Mapaipi ane ma grooves (grooves) akabatana akatevedzana, akabatana nejoint, uye switching point yakafukidzwa ne o-ring seal.

Mushanduro yekutanga, migero yekubatanidza migero yakachekwa nemidziyo yekucheka milling cutters. Yaive nzira yakaoma uye isina kunaka. Mazuva ano, chishandiso chakakosha chinoshandiswa kugadzira migero - miller grovers. Dzinosiyana nenzira yekufambisa (yemaoko kana yehydraulic) uye muhupamhi hwemapaipi adzinokwanisa kushanda nawo. Munzvimbo dzemaindasitiri, michina yekukwevera grooving isingachinji inoshandiswa, iyo inodhura zvakanyanya kushandiswa pamba. Asi pamabasa madiki kana pakugadzirisa nguva dzose, mashandiro echishandiso chinoshandiswa nemaoko akakwana.

Dambudziko rega rema "groove joints" nderekuti anodhura zvakanyanya, kupfuura mamwe marudzi. Izvi ndizvo zvinotadzisa kushandiswa kwawo zvakanyanya. Zvishandiso zvekugadzirisa mapaipi zvinodhurawo; ma "portable groovers" anodhura makumi ezviuru zvemaruble. Asi kana ukaita basa diki, unogona kurenda chishandiso; nerombo rakanaka, kugona basa racho ne "groover" hakuna kuoma zvakanyanya.

Mhando dzezvigadziko zve groove

Nheyo yezvishandiso zvepamugero inoshandiswa kuita mabasa akasiyana-siyana panguva yekuisa mapaipi. Kune mhando dzakasiyana dzezvishandiso zvakadaro:

• kubatana - shanduro yekare yakagadzirirwa kubatanidza zvikamu zviviri zvemapaipi ane dhayamita imwe chete;

• gokora - chinhu chinotenderera chepombi ine mupendero wakagadzirwa zvakanaka zvinoita kuti chibatiso chive nyore kuiswa;

• maplugi - zvikamu zvinokubvumira kuvhara bazi repaipi kwenguva pfupi kana zvachose kana kuve nechokwadi chekubatana kwe groovelock ne thread;

• maadapta akabatana - anokubvumira kubatanidza pombi ine dhayamita diki ne threaded fixation;

• flange inotsvedza - inoita kuti girobhu riende kune flange system;

• zvimwe zvinosungirirwa - mhando zhinji dzakagadzirirwa kugadzira makobvu akakombama zvakananga pajoini.

Kune ma "grooved couplings" akaomarara uye anochinjika. Ekutanga ane simba rakawanda rakafanana ne "weld". Sarudzo dzinochinjika dzinokutendera kuti ukwanise kutsiva madiki akatsauka uye kutsungirira kudzvanywa kwakanangana nekumanikidzwa. Ma "grooved fittings" anoshandiswa pamapaipi ane dhayamita ye25-300 mm, saka zviri nyore kusarudza ma "clamps" emapaipi ezvinangwa zvakasiyana-siyana. Paunenge uchitenga ma "fittings", zvakakosha kujekesa huwandu hwema "diameter" anoshanda ayo chigadzirwa chacho chakagadzirirwa. Izvi zvichabatsira kuona kana imwe sarudzo yakakunakira.
