                金屬←波紋管的耐壓性分析!

                作者: admin    來源:http://www.laobingguandao.com  時間:2019-08-28    人氣:
                  金屬波紋管作為一種柔性直抵女人耐壓管件安裝於液體輸送系╲統中,用以補償管道或機器、設備連接端的相∞互位移,吸收振到时候動能量,能夠起◆到減振、消音坐下来我慢慢跟你说等作用,具※有柔性好、質量輕、耐腐蝕、抗疲勞、耐高低溫等多項特點。
                  Metal bellows, as a flexible pressure-resistant pipe fittings, are installed in the liquid transportation system to compensate for the mutual displacement of the connecting ends of pipes or machines and equipment, absorb vibration energy, and can play the role of vibration reduction and silencing. They have many characteristics, such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance.
                  波紋管在常溫時,波卐形上不發生塑性變形所能承受的最大靜壓力,即為波紋管的最大耐壓力在一般情況下,波紋管是在一定的壓力(內壓后方是连成一片或外壓)下工作的,所以它在整〖個工作過程中必須承受這個壓力而不產生塑性變形。波紋管的耐壓力實際上屬於波紋管的強【度範疇。
                  At room temperature, the maximum static pressure that bellows can withstand without plastic deformation occurs in the waveform, that is, the maximum resistance pressure of bellows. In general, bellows work under certain pressure (internal pressure or external pressure), so it must withstand this pressure without plastic deformation in the whole working process. The pressure resistance of bellows actually belongs to the strength category of bellows.
                  計算的關鍵是應力分○析,也就是分析波紋管管壁上的應力只要波紋管管壁上最大應力點的應拳头力不超過材料的屈服強〖度,波紋管所受的壓力※就不會達到其耐壓力。同一波紋管在其它工作條件相同時,受外壓比受內壓時的穩定性要好,所以,受外壓作■用時的最大耐壓力比受
                  The key of calculation is stress analysis, that is to say, the stress on the wall of bellows will not reach its pressure resistance as long as the maximum stress point on the wall of bellows does not exceed the yield strength of materials. When the same bellows work under the same conditions, the stability under external pressure is better than that under internal pressure, so the maximum pressure endurance ratio under external pressure is better than that under internal pressure.

                  內壓時高。當波紋管兩端固定,如果在其內腔通入足夠大的№壓力時,波紋管波峰處有可能爆破刚才損壞。波紋管開始出現爆破時波◎紋管內部的壓力值稱為爆破壓力。爆破壓力是表︾征波紋管最大耐壓強度的參數。波紋他管在整個工作過程中,其工作壓力遠小於爆破壓力,否則波
                  High internal pressure. When both ends of the bellows are fixed, if enough pressure is put into the inner chamber, the bellows may be damaged by blasting. When the bellows begin to burst, the pressure inside the bellows is called the burst pressure. Blasting pressure is a parameter to characterize the maximum compressive strength of bellows. In the whole working process of bellows, the working pressure is far less than the blasting pressure, otherwise the wave
                  紋々管將破裂損壞。當波紋而后再将你長度小於或等於外徑時◤,其計■算結果和實際爆破壓力很接近;對細長型波紋管其實際爆破后续人员壓力要低很多。爆破壓力大約為允許工□作壓力的3~10倍。
                  The bellows will be broken and damaged. When the ripple length is less than or equal to the outer diameter, the calculated results are very close to the actual blasting pressure; for slender bellows, the actual blasting pressure is much lower. The blasting pressure is about 3 to 10 times of the allowable working pressure.
