Hose reinforcement layer 1 hydraulic testing machine hose rupture

Rusty steel braided hose rupture, fracture, peel off the outer layer and check, found broken wire frame near near. This is mainly due to the the layer wet or corrosive substances diluted hose strength, high pressure burst. This is enhanced in accordance with the general along with the part, abrasions or serious damage to the outer layer of loss protection. This must be checked, and turn off all the negative factors, such as mechanical damage, corrosion resistance, high temperature baking, and then replace the hose cover. However, to maintain the fracture and the fracture of the outer usually a very good reinforcing layer distance of several millimeters rusty, which causes the inner edge of the main coating is a common undesirable moisture in the hose connection 200, therefore, the reinforcing layer to absorb the moisture, cause rusting through the hose to result in a lower compression strength and fracture. (2) hose reinforcement layer will not rust, but irregular rest reinforcement layer. Peelable hose rupture valve is found, the the rusty reinforcing layer, but the the irregular breaking down the longitudinal direction of the reinforcing layer is the main reason, high-frequency hose. There are many crossing points between the wire braid layer to enhance the change of the size of the layer, if the pressure within the tube, wherein the change in the diameter of the cross point, and dislocations in the mutual friction between the wires. When high-frequency vibration, the cross-point connection failure the frequent friction pressure hose. Typically, the high-frequency shock cord bobbin should be used as a reinforcing layer. 4 hose rupture debt (1) or more of the other parts of the fracture gap neat and good performance. The reasons for this phenomenon, the system is too high, the output pressure exceeds tube. If the system pressure to meet the requirements, you should use the hose pressure to meet the requirements.stainless steel hydraulic hose fittings
 (2) hose rupture due to excessive torsion tube through the installation or use of the process to reverse this phenomenon. In the torsion of the hose in order to strengthen the the layer structural change point in the multi-chain gap, thereby the pressure resistance of the hose, breakable under high pressure hose. Accordingly, in this process, pipe, pipe fittings, use or storage does not withstand the torsion the installation hose as far as possible in the plane of movement of the two terminals on the axis quantity to avoid twisting movement of the hose. (3) hose protection mouth curled wire, the necking resort near the reinforcing layer loose this phenomenon, because of excessive tensile deformation of the hose, the layers separated, lower compressive strength. The shrinkage or elongation of the longitudinal direction of the tube occurs under high pressure, such as in a normal 2-4% of the amount of expansion and contraction. Select the short tube assembly line, a large pull of a damaged or loose serious error across too much of the weight of the hose hose hose weight, weight, failure. Solution: If you pull too hard, you should replace the tube is longer, if the span is too large, it should be added to the middle of the support folder.metric hydraulic hose fittings
