hydraulic hose assembly connection

When Hydraulic ferrules connection, pipe fittings at both ends of the connection tube best uniform material, which can effectively prevent leakage. After embedding steel hydraulic hose assembly body began efforts to tighten ferrule efforts should not be too large. hydraulic hose assembly Including pipes and pipe fittings, selection principles are: to ensure that the oil for laminar flow tube, pipe as short as possible to reduce the pressure loss; pipes and connections to determine the structure according to the working pressure, the installation location to ensure that the pipes and fittings have sufficient strength, good seal; hydraulic hose assembly and pumps, valves and other connections shall determine its interface size diameter; easy assembly and disassembly. split flange clamps to make the Hydraulic hose fittings and valve interconnected parts, connected to the pipe end. There are holes on the flange bolts so that the two flanges tightly connected. Between the flange sealing gasket. Flange points threaded connection (wire connection) flanges and welding flanges and flanged sleeve. split flange clamps is to connect two pipes, fittings or equipment, to their fixed on a flange between two flanges, plus flange gasket, bolted together to complete the connection. Some hydraulic flanges and equipment already comes with hydraulic flanges , also belong to the flange connection. Flanged connections are important pipeline construction. Flanged easy to use, able to withstand greater pressure. In industrial pipe using hydraulic flanges connection is very extensive. Within the family, the pipe diameter is small, but low pressure, invisible hydraulic flanges  connection. If a boiler room or the production site, everywhere flanged pipes and equipment. Often require a high temperature planar hydraulic flanges  temperature sealing member, if the sealant is not a good seal in a separate additional pressure region the influence of pressure, can cause inaccuracies in the production or deformed, which means that the pressure in a separate pressure zone under leakage, thus requiring unscheduled repair.

hydraulic hose assembly Installation

When we conduct bite type fittings installed, the best is to use large-caliber type of connector. Meanwhile, in order to more effectively carry out the installation and in order to effectively reduce the number of factors that we have the labor hydraulic hose fitting . When performing the installation, we first of all is to bite type fittings in the water or the location of the pump outlet opening and stop treatment, the purpose of doing so is to effectively reduce the bite type fittings due to tension or compression caused by impact. Rotary joint in the hydraulic hose couplings and storage process should avoid collision and fall, so as not to damage the interface and internal parts. Installed concentric as possible to ensure the good functioning of the rotary joint. Rotary joint threaded connection during the installation, you should pay attention to the inner and outer tubes are threaded to the direction of rotation of the drum corresponds to the inner and outer tube. No tools are able to achieve a pipeline connected or disconnected joints. Mainly used for air piping, pneumatic tool accessories. There are hydraulic fittings manufacturers  and varied body of material, size and installation of various shapes. Hydraulic hydraulic hose assembly is in addition to the power source, a control section, the application of elements outside the executive body of the hydraulic system, the other part. For example, filters, air-cooled, liquid level gauge, thermometer and more. Commonly used in the press; engineering machinery, dump truck, etc.

The use of high-pressure hose size

When the high-pressure hose be withheld , will always produce withhold too tight or too loose phenomenon, and these phenomena often lead to adverse effects of high pressure hose . Today we say it is the size of the amount withheld would it have any effect on the high-pressure hydraulic hose assemblys . We carried out by the following detailed understanding .Withhold the amount and rate of withholding high pressure hose and fittings assembly when the improper or joint structure and material , size selection is unreasonable, can lead to high pressure hydraulic hose fitting and fittings withholding too tight or too loose will cause early damage to the joints .
When assembled , if the withholding amount is too small, that is between the high pressure hose connector and cut through the loose , high pressure hose there may emerge in the role of oil in the early use from the joint ; If withholding is too large, then the connector and hydraulic hose fittings too tight , easily lead to hose inner being localized damage, cracks , directly into the high-pressure oil from the ruptured steel layer , and then he went to the wire along the gap between the spray coat tails , or has fled somewhere along the wire layer build up , so that the outer layer of plastic to produce drum kits and even rupture . Hoses and connectors in the assembly, if the withholding too fast, likely to cause damage to the plastic layer and the wire break, so that premature failure of the hose in use .
The above information is very detailed description of the effect of the size of the amount withheld for the use of high-pressure hose produced , so we need considerable attention when using this withholding his dosage size is accurate, whether the mutation will produce high pressure hose , etc. problems should close attention.

The role of the metal hose

Metal hose used for automated meter signal wire protection tube and instrument meter circuit protection tube for protection, the protection of precision optical ruler, protecting the sensor lines threading stainless steel metal hydraulic adapter, metal hose electrical protection; stainless hydraulic hoses, softness is good, dustproof, waterproof, anti-oil, anti-rust; anti-wear, and provide some shielding effect. Sensing for precision optical ruler of circuit protection, industrial sensor circuit protection. Has good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile strength.

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 .

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.

factors that affect the use of the hose assembly

Many factors will affect the use of the hose assembly . The first is the size of the hose . Inner diameter of the hose to the right, if it is too small, will affect efficiency. If the inside diameter is too large, will affect the overall system performance of the play. Therefore , it is important to select the appropriate inner diameter . Second ,hydraulic adapter  will also affect the temperature range of use. If the hydraulic hose working environment temperature exceeds the specified range , then the hydraulic hose pressure capacity will thus be greatly reduced. Experts suggest that if the high or low temperature working environment , should be put on the hydraulic hydraulic hose fitting jacket . In addition to the above two factors , the use of hydraulic hose assembly Hose working pressure is also affected by the impact stress and fatigue life , impact bending radius and chemical compatibility and other factors.Hydraulic hose assembly in our lives is very wide, in the mining industry , agriculture and industrial sectors have a lot of use . It is transmitted through water and gas or oil substance hydraulic power to ensure adequate fluid energy during operation.
