Tightening te wa e tika

i huaina taipana ko kaha hurihuri, ie tightening te nati. whanganga kaha hurihuri i roto i Newton te ia mita 1 - Numbers. No te karapiti, e e whakapuru tutaki taipana hua te kawenga axial runga ratou. Te kawenga axial (axial) - he ope e mahi i runga i te mata o te huānga tātari. Ka taea e arahi te reira ki te deformation o te huānga pakaru o te raunga ranei. I te wa o te tightening o nga raka o te pānga puna kitea te.

A, no te tightening puta te mānukanuka nati tutaki, te tuuraa o te piki kawenga. kawenga Axial Ko te mahi tika o te ope waku. Ki te taui te reira, na pono hoki tera ano he huringa i roto i te kawenga ite e te ararewa. Hei tōpana puta nga raka i runga i nga tikanga katoa, e hiahia ana koe ki te whakahinuhinu ratou ki nati me mōria. Uehā awenga kawenga, me te ko te kaupapa matua nui o te karapiti whakaminenga. piri te taipana te wāwāhi tōpana motuhake. Heoi, i reira he ara tika atu e pā te taipana o nga raka, me te hua mutunga.

He aha kia te kaha i runga i te raka honotanga?

Ko te tutaki kokopi karapiti tūhonohono. Me tightened te taipana tightening o raka kia kia rite ki te pupuri i te kawenga i runga i te gasket me pāmahana pata, me te pēhanga anō i roto i te tukanga noa, a ka pressurized te pūnaha te.

I roto i etahi hononga ara mahi kawenga pŭpŭ tauturu. Na ka taea ki te urutau i nga wa katoa, me te tonu kia raru te hononga tutaki he.

Ko te tukua kaha o te rauemi i nei te tutaki hangaia he kawenga, tuku totoro reira ki tona mōrahi roa whakaaetia, i muri nei hoki i te reira ki tona āhua taketake. Totoro taea e i roto i te taikaha o te tukua mehua whakaaetia. I roto i tenei take, ka nekehia atu te kawenga kei, tavini te tutaki rite te ahua o "hoki puna".

A, no te nui o te kaha tightening tutaki te, totoro puta tukua tīkina ahotea, e arata'i ki te whakaiti kawenga. A, no te tightening Me nga pokekore ki te kia tupato ki te kore toia puta e ka arahi tika ki spoilage. Tightening taime - he tukanga mahi a, kuo pau ke tau whakarite e te tapeke kawenga i runga i te papa kei te āta ngoikore, i runga i te tauine o 40-100% kaha tukua. he tika ki te kia kihai i e huri i te tapatahi o gaskets, karapiti hoki reira. Ngaohiko whakaaetia nei ki te tono ki te mata o te gasket kore e nui ake te uara tomu'a. He kōwhiringa o te tutaki e tika ana ko te huru e tika ana mo te mahi hononga flange.

Me pēhea te ki te ū ki te tightness?

E rua ngā āhuatanga e Me tutaki:

1. Effort, mahia ki te whāinga o te pēhi i te gasket me pupuri i te reira i roto i te wahi. Me kia raka Utaina pērā i romia te gasket puta noa te mata o te flange.
2. Ko te ope i te mea e tika ana ki:

• Hei haere te kawenga hydrostatic.
• aki ana te gasket te ka puritia pahoho, a kihai i whiwhi i te pēhanga i roto.
• Whakaorangia te kawenga i runga i te Unuhia i muri i te kawenga hydrostatic.
