hydraulic hose hydraulic hose jacket adds stability

hydraulic hose hydraulic hose jacket adds stability
Hydraulic hose strip actual width, as already mentioned, the theory must be less than the width of the specific value depends on the hydraulic hose nets coverage ratio size.
       Braid angle generally  take 30 to 45 in the other parameters is determined, in order to ensure a certain carrying capacity hydraulic hose, braid angle can also be appropriately reduced. parher british fittings In recent years the introduction of equipment for hydraulic hose seems foreign to the braiding angle values, the smallest only 15. Value of the size of the braid angle, directly affects the performance of hydraulic hose. If we take the upper limit, is conducive to play it soft features, but can not withstand high loads; if off limits, hydraulic hose can withstand high loads, but not conducive to play its softness properties.
       Nets for hydraulic hose coverage ratio is generally controlled at 75 to 95 percent range, if the value is too large, the repressed hydraulic hose soft characteristics; if the value is too small, will serve to protect the hydraulic hose from knock , touch, grind, hit other mechanical injury. Its value has a direct impact on the size of the performance of hydraulic hose, meaning just the opposite angle weave, if we take the upper limit, hydraulic hose can withstand higher loads, but not conducive to play it soft characteristics; if we take the lower limit value, is conducive to play it soft features, but can not withstand high loads.
      Hydraulic hose steel spindles is generally an even number greater than or equal to 4, the hand-woven, as long as this range are feasible; but mechanical knitting is concerned, parher bsp threads on the difficult. Domestic knitting machine setting a fixed number of spindles, and is not adjustable. Therefore, the number of hydraulic hose steel ingot is best knitting machines based on the existing number of spindles to determine.
      At present, the domestic knitting machine with 24, 36, 48, and 64 have been introduced along with the. However, they are designed to weave wire mesh sleeve, weaving out of the "double flower" parher hydraulic hose assemblies pattern; while steel braided preferably in the form "single flower" pattern.
