Assembly of sleeve type pipe joint
(1) Pre-installed the most important link of the pre-installation of the sleeve type pipe montaža direktno utiče na pouzdanost pečata. Posebni prekursori su općenito potrebni.oprema sa malim prečnikom može biti pre-sastavljen na klupi stege. Specifičan pristup je korištenje a montaža as the matrix, the nut, clamping sleeve can be pressed to the pipe. There are mainly sleeve type through pipemontaža, sleeve type end through connecting head, sleeve type three-way pipe montažaand other types. TO JE found that even for a batch of goods from the same manufacturer, the depth of the conical hole on themontaža is often not the same, resulting in leakage, and this problem is often ignored. The correct way is to use what kind of montaža se koristi na jednom kraju cijevi, a na odgovarajućem fiting tail is pre-installed with the same type of montaža, so as to avoid leakage problems to the greatest extent. The end face of the pipe should be flush.
(2) After the pipe is sawed, it should be polished evenly on grinding wheel and other tools, and the burrs should be removed, cleaned and cleaned with high pressure air before use.
(3) During pre-installation, the coaxiality of the pipe and the montaža should be kept as far as possible. If the pipe is too deviation, it will also cause sealing failure.
(4) 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.
It is forbidden to 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.
(3) When connecting the pipe, the pipe should have enough deformation allowance to avoid the pipe being subjected to tensile force.
(four) When connecting the pipeline, it should avoid being subjected to lateral force, which will cause loose sealing if the lateral force is too large.
(five) when connecting the pipeline, it should be good once and avoid multiple disassembly, otherwise it will make the sealing performance worse.
Folding card sleeve type pipemontaža instalacija
(1) Prvo se vrši kiseljenje cijevi iz Poglavlja 9;
(2) Cut the pipe according to the required length with sawing machine or special pipe cutting machine and other tools, it is absolutely not allowed to dissolve the pipe (such as flame cutting) or grinding wheel cutting; Remove burrs inside and outside the pipe end, metal chips and dirt; Remove the anti-rust agent and dirt of the pipemontaža; U isto vrijeme kako bi se osigurala zaobljenost cijevi;
(3) the nut, the sleeve has been set into the pipe, the front edge of the sleeve (small end) from the pipe mouth at least 3mm, and then the pipe into the montažat body cone hole, top until;
(4) Slowly tighten the nut, turn the pipe until it does not move, and then tighten the nut 2/3 to 4/3 times;
(5) Otvorite i provjerite da li je plašt urezan u cijev i da li je položaj ispravan. Jakna ne smije imati aksijalno pomicanje, već malu rotaciju;
(6) Tighten the nut after passing the inspection.
