Cad iad na réamhchúraimí atá ann le haghaidh scriúnna scriúnna hinge saincheaptha?

Determined under the most common scenario of determining the flange. Assuming you want to pay attention and act according to all the above points, including the use of coated washers, nuts (it may also be recommended to use long nuts, such as GB6170 or DIN934), in the order of the diagonal of the nut, gradually, to change the proper The tightness, etc., if it is still not possible, it is often impossible to remove it after the early determination. At the end, you have to ask the flange to confirm the installation. Temporarily use carbon steel nuts before the first, until the end is temporarily unlocked on the surface, and stainless steel is used for rust prevention. When nut, don't find a balance point between them.

C: An bhfuil sé dÚsachtach luas daingean a úsáid i gcónaí nuair a bhíonn scriúnna hinge cruach dhosmálta á n-úsáid?

Freagra: Más é an chéad uair nó an t-úsáideoir gan aithne ar an táirge próiseas scriú hinge cruach dhosmálta, ba cheart duit dul i gcomhairle le do sholáthraí cruach dhosmálta féin le haghaidh na saintréithe ábhartha. Faoin gnáthchás céanna, is féidir le ráta cinnteoireachta mall a bheith ina chaillteanas ollmhór (nó fiú cosc ​​iomlán a chur ar thréimhsí neamhbheartaithe ócáideacha). Ós rud é go dtarlaíonn teas go minic ag amanna cinnte, de réir mar a mhéadaíonn fuinneamh teasa, mar sin freisin an dóchúlacht go dtarlóidh glas. Nuair a bhíonn sé in úsáid, ba cheart go gcinnteofaí go mbeadh ráta an scriú cruach dhosmálta níos ísle ná an ráta glasála-suas cruach carbóin.

C: An gcinntear an chéad scriú nó cnó réidh riamh?

Answer: Assuming the answer is "No", it may be recommended to use butter, molybdenum disulfide, graphite, mica or talc to smooth the inner and outer rib, in order to reduce the occurrence of deadlock. The buckle hand (coating) is an effective smooth weave, rewarded by the treatment of the buckle stop nut, which will be like a screw cap and between the rib of a smooth film.

C: Roghnú scriúnna hinge agus cnónna sa ghrád ábhar céanna?

A: Más amhlaidh, is féidir leat gráid éagsúla scriúnna agus cnónna hinge a úsáid, mar shampla moltaí 304 agus 316. Ach ní mór aird a thabhairt ar roghnú brandaí cruach dhosmálta chun a gcuid riachtanas meirge agus friotaíocht creimeadh a chomhlíonadh.
