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.
