Shrink cable joint processing preventive measures and treatment

After stripping the cable insulation , the main application of fine sandpaper carefully polished surface of the insulation layer , making it smooth and no marks, no semiconductor residual points . The insulation must be cleaned with a cleaning solvent shield direction from the core to the semiconductor , do not use the shield layer in contact with the semiconductor cleaning paper to clean the main insulation layer on the surface .After crimping wire core , application file, sandpaper carefully polished to eliminate edges and tip , and pay attention to metallic particles may not remain on the surface of the insulating layer .Special attention should be in the process of making the cable connector to keep clean , and should try to shorten production time , after stripping the cable cut , exposed in the air longer, the possibility of invasion of impurities , water , gas , dust, etc. , the greater , thus impact of joint quality . Therefore required before construction to do all the preparatory work to ensure the production of non-stop , go.
    Before making hydraulic hose fittingto carefully check the cable accessories and cable facilities, so as to strictly control the amount of interference shrink silicone rubber insulating sleeve , to ensure that they have sufficient grip force , close contact with the interface , there is no gap .
    Semiconductor adhesive tape were wrapped in shrink after each phase of silicone rubber composite insulating sleeve two port. Thus , both the silicone rubber outer casing outside the semiconductor layer and semiconductor XLPE cable shield good contact , but also play a role in the axial waterproof .
    Surrounding the self-adhesive waterproof tape, shrink Hydraulic pipe fittings seal is proof key to a semi- joint overlap method from one end to the other end wrapped and then wrapped in the opposite direction from one end to the starting side, wrapped in two layers. After each wrapped with both hands clasped in turn again, to make it better bonding. Be sure to pull when properly wrapped , so tightly wrapped seamless .

Micro oil-resistant high-pressure hose .

Micro oil-resistant high-pressure hose .
  Such high pressure hose , mainly used in coal mine hydraulic bracket , dosage particularly large, some large mines , the amount to tens of millions a year , and say it is very terrible , there are times , I Inner Mongolia, in a large warehouse to see mine that a lot of hydraulic hose assemblys, looks like a hill heap. In particular, some caliber 152 , and 204 largehydraulic hoses , each root to all kind of scary to see the value of money. That fight was convinced that this market is quite large . Secondly, in terms of performance and practical with low agricultural equipment.

High pressure hose and fittings assembly withhold the amount and mode selection improperly withheld

High pressure hose and fittings assembly and withhold the amount of the withholding way inappropriate choice . Or joint structure, material , size selection is unreasonable, can lead to pressure hose and fittings too tight or too loose , causing early damage joints . Assembly , if the withholding amount is too small , that withhold joints between the weight of too loose with the hose when under the effect of the hydraulic hose assemblys during the initial period there may emerge from the joint ; withheld if excessive , then withhold joints and hose too tight , easily lead to the hose inner layer of localized damage , deformation, cracks , high pressure oil from the weak rupture directly into the layer of wires , and then he went along the gap between the wire coat tail ejected , or along the wires of the layer has been somewhere he went to build up , so that the outer plastic drum kits produced even rupture . Hose and connectors in the assembly, if the withholding too fast, easy to cause damage to the inner rubber layer and wire breakage , so that premature failure of the hose in use . In addition , the joint design is unreasonable , jerry , processing of poor quality, can also cause damage to the inner glue ; if improperly fitting material selection , not reach high pressure hose assembly requirements. Will shorten the life of high pressure hose .

Fittings prevention and installation methods

Fittings prevention and installation methods In the hydraulic system , both the metal pipe fitting , or hose fittings , there are prone to leakage problems . For fittings fittings fittings fittings, mostly due to pipeline subject to greater external force or impact force, the card sets loose or deformed face caused by leaking pipe , you should check whether the card holder out of round , edge whether the defect , Hydraulic pipe fittings end is intact and nut, compression level , etc., while also eliminating pipeline force. For flared fittings, mostly due to excessive flaring , quality, undesirable or multiple demolition , resulting in flared cracks or deformation caused by leaks , then you can be re- flared front truncated . If you use a malehydraulic hoses and female cone top pressure seal , the leakage is mostly due to two cone damage, available on the cone abrasive grit grinding . In some with "о" or outer -ring face seal by the occasion , the leakage following reasons : "о" ring aging or deformation caused by leakage ; "о" ring assembly is not in place , so that the two plane connection when pressure is uneven or "о" ring is cut resulting in leakage.

Flared fittings Appearance process

Appearance of the product is also very important, flared fittings, too. Rough coarse hair hose during use is bring a lot of inconvenience, such as glitches, injured his hand how to do, affecting the appearance of the new factory, the customer that the product is not worth the price of how to do, export expansion pipe joints products, foreign clients do not recognize how to do, there will be many complicated problems. Therefore, we should pay attention to the appearance of products, customers see first is the appearance, so we handle flared fittings appearance.hydraulic fittings appearance processing recommendations are as follows:
1, the hoses in polishing, painting problems when handling.
2, tube hydraulic flanges hinge bolt final polishing, pickling, etc.
3, hydraulic flange welding process technical problems.
4, stainless steel hose problems during the packaging process.
5, and other related operations scratching and so on.

Welded pipe joints for oil pipeline system for the medium

Welded pipe joints Uses and characteristics junction 1 . Welded pipe joints Uses: Welded pipe joints for oil as the medium of piping systems, piping systems for water and air pressure are also used . Working pressure of less than or equal 32Mpa.2. Hydraulic pipe fittings : welded pipe joints has a simple structure , easy to manufacture , sealing , etc., but when installing large welding , welding quality requirements .3 . welded pipe joints structure: welded pipe joints which consists of fitting body nuts and takeover components. took over the joint between the body and the O- ring seal when screwed into the body when the connector body , metric fine thread and cone pattern. and the use of combined sealing gaskets. takeover pipes and piping systems welding hydraulic fittings manufacturing standards 1 , for fluid power and general use metal fittings O-ring hydraulic tube fittings 2 plane , cone seal welded straight couplings 3 , cone seal welded through 55 ° non- sealed tube threaded pipe joint 4 , cone seal welded through 55 ° sealing pipe thread fittings 5 , cone seal welded through 60 ° sealing pipe thread fittings 6 , 90 ° cone seal welded elbow
