A container of beautifully packed layflat hose will be delivered
The correct selection of hydraulic hoses can ensure the safety of the entire hydraulic system, reasonably arrange space, and better control costs. The main points to note are:
First, according to the pressure of the system, the number of steel wire layers of the hydraulic hose is selected. The pressure is high and the number of steel wire layers is large. Each hose has a maximum working pressure, and the burst pressure of the hose is 4 times the maximum working pressure. The higher the pressure resistance of the hose, the higher the price will be, so according to the actual system pressure, the maximum working pressure of the selected hose can be greater than the actual working pressure. If the system’s impact pressure is frequent, use a special pulse-resistant hose.
Second, the inner diameter of the hose is selected according to the flow rate. If the diameter is too small, the flow rate of the medium in the tube will be increased, which will cause the system to heat up and reduce the efficiency. It will also generate an excessive pressure drop that affects the performance of the entire system. Cost, so the inner diameter of the hose must be appropriate. When the hose is fixed with a pipe clamp or the hose passes through a spacer such as a steel plate, pay attention to the outer diameter of the hose.
Third, you should pay attention to the bending radius of the high-pressure hose when selecting the high-pressure hose. The buckling length of the front joint should be subtracted when calculating the bending radius. If the bending radius of the installed hose is too small, it will reduce the pressure bearing capacity of the hose and affect its life.
Fourthly, it is necessary to reasonably select the joint form according to the hydraulic arrangement, such as: flange joint, internal thread joint or external thread joint, etc., such as the joint angle and the overall hose assembly angle.
