Assembly of sleeve type pipemga kahimanan

Preinstallation the most important link of the preinstallation of the sleeve type pipemga kahimanandirekta nga makaapekto sa pagkakasaligan sa selyo. Espesyal nga precursors kasagaran gikinahanglan.Pagpahiangays with small diameter can be preassembled on the bench vice. The specific approach is to use amga kahimanan as the matrix, the nut, clamping sleeve can be pressed to the pipe. There are mainly sleeve type through pipemga kahimanan, sleeve type end through connecting head, sleeve type three-way pipemga kahimananand other types. The author found that even for a batch of goods from the same manufacturer, the depth of the conical hole on themga kahimanan body is often not the same, resulting in leakage, and this problem is often ignored. The correct way is to use what kind ofmga kahimanan body is used at one end of the pipe, and the correspondingmga kahimanan katapusan kay pre-installed uban sa sama nga matang sa mga kahimanan, aron malikayan ang mga problema sa leakage sa labing dako nga gidak-on.

Ang tumoy nga nawong sa tubo kinahanglan nga flush. Pagkahuman sa tubo, kini kinahanglan nga gipasinaw nga parehas sa paggaling nga ligid ug uban pang mga himan, ug ang mga burr kinahanglan nga tangtangon, limpyohan ug limpyohan sa taas nga presyur nga hangin sa dili pa gamiton.

 During pre-installation, the coaxiality of the pipe and themga kahimanan 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 mga kahimanan

(1) Ang pag-pickling sa mga tubo nga gikinahanglan sa Kapitulo 9 kinahanglang himoon una;

(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 pipemga kahimanan; Sa samang higayon aron sa pagsiguro sa roundness sa pipe;

(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 themga kahimanan 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) Ablihi ug susiha kon ang dyaket naputol na ba sa tubo ug kon husto ba ang posisyon. Ang dyaket dili gitugotan nga adunay axial nga paglihok, apan gamay nga pagtuyok;

(6) Tighten the nut after passing the inspection.
