Tightening yakakodzera

Torque anonzi rotational simba, kureva tightening manatsi. rotational simba unotaurwa Newtons por mita 1 - Shona. For flanges, dziri kuwedzera bhaudhi torque unobereka imwe axial mutoro pamusoro pavo. The axial mutoro (axial) - samba anoita pamusoro kumucheto firita maatomu akafanana. Kunogona kukonzera deformation yacho chinhu kana kuwa containment. Panguva tightening pakati kukurova chitubu kushanda ari kuchengetwa.

Kana tightening ari nati bhaudhi makakatanwa kunoitika, kuturika mutoro inowedzerawo. Axial mutoro vanoshandiswa kushanda kukweshera simba. Kana anoshandura, ipapo zvirokwazvo pane shanduko iri mutoro kwakaitirwa lining. Kuti torque nekiyi kwakaitika pamusoro zvose mitemo, unofanira tsvedzesa navo nzungu uye the washers. Ekisero mutoro kunechekuita uye zvinokosha pokutanga nekereke flanges. The torque wanamatira chaiyo torque chipanera. Zvisinei, pane nzira dzakawanda yakarurama kuti kukanganisa torque pakati nekiyi uye kuguma mugumisiro.

Chii chinofanira kuva simba riri unobatanidza nemipande?

Bhaudhi anorumanya interconnected flanges. The tightening torque kuti kukurova anofanira akasungirirwa kuitira kuchengeta mutoro pamusoro gasket netembiricha madonhwe, uye kumanikidza differential mune kuipa muitiro, uye kana gadziriro pressurized.

Mune dzimwe nzira kubatana kuita upiyona mutoro. Ipapo bhaudhi kubatana anokwanisa kuchinja nguva dzose uye vachiri kuva zvakasimba.

The goho simba yemashoko iyo kugadzirwa bhaudhi iri mutoro, kuubvumira ruoko ayo kunonyanyisa bvumidzwa urefu, pashure pacho anodzokera ayo hwepakutanga. Munotatamura anogona zvinopfuura bvumidzwa matanho zvibereko. Panyaya iyi, kana mutoro yabviswa, bhaudhi anoshanda sekanguva "tsime kudzoka".

Kana bhaudhi tightening simba iri kupfuura, achitambanudza kunoitika zvinobvumidzwa goho kushushikana, iyo inotungamira kuti mutoro rutapudzo. Kana tightening kuti screws vanofanira kungwarira kuti kwete kukweva kwakaitika kuti zvakarurama kuchaita kuti spoilage. Tightening Nguva - a rakaoma muitiro, tinofanira kuva nechokwadi chokuti nhamba mutoro pamusoro ikanyanya iri zvishoma nezvishoma kwaderera, pamwero wenyika 40-100% zvibereko simba. Zvinokoshawo kuva nechokwadi chokuti haana kushandura pakururama gaskets, flanges. Voltage iro vabvumirwe zvinoshanda pemvura gasket haafaniri kupfuudza akafanorongerwa ukoshi. A akakodzera kusarudza zvechizarira chinhu chinodiwa chimiro basa flange papi.

How kutevedza tightness?

Two zvinhu zvinofanira akasangana:

1. Kuedza, akaita nechinangwa vachisundira gasket kuiita panzvimbo. Mutoro nemipande kunge zvokuti gasket kusvinwa mhiri pechiso flange.
2. The simba iro zvaanofanira:

• Zvakaitika hydrostatic mutoro.
• The gasket rikazvisundira uye wakabatanidzwa mira, saka kuti kumanikidza haana kuwana mukati.
• Ponesai mutoro pamusoro wonamatidza mushure hydrostatic mutoro.
