By utilizing high pressure hose and connector assembly and pressing speed selection

By utilizing high pressure hose and connector assembly and pressing speed selection, or joint structure and material, size selection is not reasonable, can lead to high pressure hose and fittings withhold too tight or too loose, can cause joint damage early.The assembly, if the withholding amount is too small, the joint and the high pressure hose pressure too loose, under the action of oil pressure hose at the initial stage of use is likely to emerge from hose fittingthe joint; if the withholding amount is too large, joint and hose pressure too tight, easily lead to hose inner layer by local damage, crack, high pressure oil from the ruptured directly into the wire layer, then along the rear of the jet slot channeling to coat steel wires, or has been along the wire layer channeling somewhere accumulates, the outer layer of hydraulic tube fittingsdrum kits and even cracking. Hose and connector in the assembly, if press speed too fast, easy to cause damage and fracture of the glue in the wire layer, so that the hose damage early in use.
The above information is very detailed description of the effect of the size of the withholding amount produced using high-pressure hose, so we use the press to considerable attention, he dose size is accurate, if the high pressure hose mutate and so on should pay close attention.

Copper brazed directly Problems

Direct Copper brazing mainly two: the need to use corrosive aluminum brazing agent to remove the oxide film, moisture absorption flux residues form an electrolyte constituting the strong corrosive; aluminum, copper atoms diffuse faster, easier plastic Hydraulic adaptersconnector in the package forming fusible eutectic brittle, leading to joint strength is low, and the electrode potential than the electrode potential is high, prone to intergranular corrosion. Thus, aluminum and copper is generally believed that direct brazing is difficult. In order to prevent oxidation of solder joints, preferably in an inert atmosphere, the production of furnace, heating by hydraulic hose fittingresistance heating or flame brazing.
In order to avoid the formation of aluminum and copper brittle compounds, aluminum and copper atoms necessary to avoid direct contact, and to avoid corrosive flux caused by corrosion problems, can be coated on the surface layer of metal (such as nickel), and then with Brazed , to avoid the formation of aluminum and copper brittle compound, but also can be used corrosive or non-corrosive flux, thus increasing the joint strength and corrosion resistance.

Pack plastic hose connector installation and application

Plastic coated metal hose is mainly used for the production, processing cable protection. Because plastic coated metal hydraulic hose assemblys with light weight, good flexibility and strength of the connection accessories, electrical properties and oil, splash water and other features, so often widely used in electric power, chemical industry, metallurgy, light industry, machinery and other industries. hydraulic hose fittings plastic bag purpose is to protect the wire and cable and insulation, waterproof, can increase the cable bend beautiful.Although compressible metal hose can stretch, but if you do not install the correct position, it will soon break, reduce the service life. Hose plastic bag selection, reference should be corrosion hose material machines and corrugated plastic coated metal hose DN, use, the first cable wires through the pipes, matched with the corresponding model DPJ type connector that available.

High pressure hose for the oil and rubber inner wall

High pressure hose for the oil and rubber inner wall , in the middle of braided steel wire ( steel braided hose ) or winding wire ( wire winding hose ) . Poor quality of the hose will appear : plastic wall of uneven thickness ; steel braided too tight ( wire stroke is small ) , too loose ( steel travel large ) or wire root too few ;hydraulic ferrule pressurized deformation ( elongation , shortening or bending deformation ) larger ( national standard steel stroke control of plus or minus 3 ) ; airtight plastic outer lead wire corrosion poor ( main manifestations : Lu steel ) ; inner plastic seal is poor leaving the high pressure oil easily into wire layer ; adhesion layer and layer of wires inadequate . The above conditions can cause hydraulic hosesto withstand reduced, eventually appears at the wall of the weak burst. Especially in the inner layer , poor air tightness , then a pressure, it leaks, then the pressure directly burst.

High oil and high-pressure hose

High oil and high-pressure hoseSuch highhydraulic tube fittings , mainly used in construction machinery , the use of high strength , high frequency . Strong corrosion resistance and pressure resistance . We can see a lot of construction vehicles, especially excavators, particularly evident , it is now everywhere, not only that, the excavator head is getting bigger , the job has become increasingly pursuit of high intensity , heavy , frequent trend.

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 .

Selection of high-pressure hose assembly

Hose sheathing installed in the main hydraulic hose, wire, cable and other products outside. Its function is reinforced hydraulic hose, wire, cable and other interior products, wear-resistant, antistatic properties, in a variety of harsh environments such as inside of Jic hydraulic fittings hose products play a security role.hydraulic fittings, wire, cable and other product installation screw protective cover not only improve the aesthetics, but also can extend the life of the product inside. Retaining spring with traditional metal products, rubber hose protector easy to install and better wear resistance; anti-aging, corrosion resistance strong; more powerful hydraulic hoses, wires, cables and other products for anti-aging and anti-surface friction protection; has more excellent, more convenient, more environmentally friendly energy-saving effect.
