Samestelling van klemhulsverbinding

Assembly of sleeve type pipetoebehore

Preinstallation the most important link of the preinstallation of the sleeve type pipetoebehorebeïnvloed die betroubaarheid van die seël direk. Spesiale voorlopers word gewoonlik benodig.Fittings with small diameter can be preassembled on the bench vice. The specific approach is to use atoebehore as die matriks kan die moer, klemhuls teen die pyp gedruk word. Daar is hoofsaaklik hul tipe deurpyptoebehore, moutipe einde deur koppelkop, moutipe drierigtingpyptoebehoreand other types. The author found that even for a batch of goods from the same manufacturer, the depth of the conical hole on thetoebehore body is often not the same, resulting in leakage, and this problem is often ignored. The correct way is to use what kind oftoebehore body is used at one end of the pipe, and the correspondingtoebehore einde is vooraf geïnstalleer met dieselfde tipe van toebehore, om lekkasieprobleme tot die grootste mate te vermy.

Die eindvlak van die pyp moet gelyk wees. Nadat die pyp gesaag is, moet dit eweredig op slypwiel en ander gereedskap gepoleer word, en die brame moet verwyder, skoongemaak en skoongemaak word met hoëdruk lug voor gebruik.

 Tydens pre-installasie, die koaksialiteit van die pyp en dietoebehore body should be kept as far as possible. If the pipe is too deviation, it will also cause sealing failure.

The pre-installed force should not be too ambassador that the inner edge of the sleeve is just embedded in the outer wall of the pipe, and the sleeve should not be obvious deformation. When connecting pipes, assemble according to the specified tightening force. The clamping force of the 6-1 sleeve is 64-1 15N, 16ф MMR 259N, ф18mm for 450N. If the jacket deformation is serious in pre-installation, the sealing effect will be lost.

Do not add sealant and other fillers. Some people in order to achieve better sealing effect, in the card sleeve coated with sealant, the sealant was rushed into the hydraulic system, resulting in hydraulic components Yin nihole blockage and other faults.

When connecting the pipe, the pipe should have enough deformation allowance to avoid the pipe being subjected to tensile force.

When connecting the pipeline, it should avoid being subjected to lateral force, which will cause lax sealing if the lateral force is too large.

When connecting the pipeline, it should be good once and avoid multiple disassembly, otherwise it will make the sealing performance worse.

Installation of sleeve type pipe toebehore

(1) Belegging van pype wat in Hoofstuk 9 vereis word, moet eers uitgevoer word;

(2) Sny die pyp volgens die verlangde lengte met saagmasjien of spesiale pyp snymasjien en ander gereedskap, dit is absoluut nie toegelaat om die pyp op te los (soos vlam sny) of slypwiel sny nie; Verwyder brame binne en buite die pypkant, metaalskyfies en vuilheid; Verwyder die anti-roesmiddel en vuilheid van die pyptoebehore; Terselfdertyd om die rondheid van die pyp te verseker;

(3) die moer, die huls is in die pyp gesit, die voorkant van die huls (klein punt) vanaf die pypmond ten minste 3 mm, en dan die pyp in dietoebehore body cone hole, top until;

(4) Draai die moer stadig vas, draai die pyp totdat dit nie beweeg nie, en draai dan die moer 2/3 tot 4/3 keer vas;

(5) Maak oop en kyk of die baadjie in die pyp gesny is en of die posisie korrek is. Die baadjie mag nie aksiale beweging hê nie, maar 'n bietjie rotasie;

(6) Draai die moer vas nadat jy die inspeksie geslaag het.
