China 30202 rullaluistemadka tapered, saarayaasha safka ah iyo alaab-qeybiyeyaasha

30202 rullaluistemadka duuban, hal saf oo sawir leh

30202 rullaluistemadka duuban, saf keliya

Sharaxaad Gaaban:

Xadhkaha rullaluistuyada safafka ah ee hal saf ah ayaa loogu talagalay in lagu qaado culaysyada la isku daray, isla mar ahaantaana samaynaya culeysyada radial iyo axial. Khadadka saadaasha wadooyinka orodku waxay ku kulmaan meel caadi ah oo ku taal dhidibka xajinta si ay u bixiyaan ficil rujineed oo run ah oo sidaas darteed daqiiqado yar oo is jiid jiid ah inta lagu jiro hawlgalka. Culayska axial-ka ee xambaara xadhkaha rullaluistudhka duuban waxa uu kordhiyaa xagasha xidhiidhka α. Baaxadda xagasha xidhiidhka, oo inta badan u dhaxaysa 10° iyo 30°.

Astaamaha rullaluistuyada duuban

1. Khilaaf hoose
Naqshadeynta dhamaadka rullaluistuyada la hagaajiyay iyo dhamaadka dusha sare ee flange waxay kor u qaadaysaa samaynta filimka dufanka leh, taasoo keentay khilaaf hoose. Tani waxay sidoo kale yaraynaysaa kulaylka jilicsan iyo xirashada flange.

2. La xoojiyey isku halaynta shaqada
Dhammaystirka dusha sare ee la hagaajiyay ee dusha sare ee xidhiidhka ee rollers-ka iyo jidadka orodka waxay taageertaa samaynta filim saliideed hydrodynamic.

3.Consistency ee profiles roller iyo size
Dulqaadyada cabbirka iyo joomatari ee biraha duuban ee duuban waa isku mid. Tani waxay bixisaa qaybinta ugu fiican, waxay yaraynaysaa buuqa iyo gariirka, waxayna awood u siisaa in si sax ah loo dejiyo.

4. Codsi xanbaarsan oo adag
Hal saf oo rullaluistir ah oo duuban ayaa sida caadiga ah lagu hagaajiyaa rullaluistemadka labaad ee duuban. Marka la codsado horudhac, codsi xajin adag ayaa la gaari karaa.

5.La kala saari karo
Giraanta gudaha oo leh rullaluistemadka iyo qafiska (koobta) waxaa lagu dhejin karaa si gooni ah giraanta dibadda (koob).
