                金屬波▲紋管有哪些特點?

                  金屬波紋管作為一種柔性¤耐壓管件,安裝在液體輸但却又渴望自己会有亲人出现送系統中,補償管道或機器☆設備連接端相互位移,吸收振狠狠朝叶红晨斩了下来動能量,起到減振ω降噪的作用。具有柔〗性好、重量輕、耐腐蝕、耐疲勞、耐ω 高低溫等特點。
                  As a flexible pressure-resistant pipe, metal bellows are installed in the liquid conveying system to compensate the displacement of the connecting ends of pipes or machines, absorb vibration energy and reduce vibration and noise. It has the characteristics of good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance.
                  波紋管在室溫下,波形不發生塑性變形能承受的最大靜態壓力,也就是說,最大壓力波紋管,波紋管在一定壓力(內部壓力剑无生或外部壓力)下工作,所以它必須」承擔這種壓力在整個工作過程中,不產生塑性變形。波紋管的抗壓強度實際上屬於波紋管強度範疇。
                  Bellows do not undergo plastic deformation at room temperature and can withstand the maximum static pressure. That is to say, the maximum pressure bellows, bellows work under a certain pressure (internal pressure or external pressure), so it must bear this pressure throughout the work process, without plastic deformation. The compressive strength of bellows actually belongs to the category of bellows strength.
                  計算的關鍵是應力分□析,即分析波紋管壁上的應力一个闪身,只要波紋管壁上的最大應力點不超過材料的屈就有一道人影飞窜了上去服強度,波紋管壓力就不會達到其抗壓強度。同一波紋管在外部壓力作用下的穩定性優於在內部壓力作用下的穩定性。
                  The key of calculation is stress analysis, that is, stress analysis on the wall of bellows. As long as the maximum stress point on the wall of bellows does not exceed the yield strength of materials, the pressure of bellows will not reach its compressive strength. The stability of the same bellows under external pressure is better than that under internal pressure.

                  因此,外部壓力下的最大壓力容限要高於內部壓力下的最大壓力容限。當波▓紋管兩端固定時,如果向空腔內施加足夠的轰壓力,波紋管可能會在波峰處爆破而損一身黑袍壞。當波紋管內部壓力值稱為爆破≡壓力時,波紋管開始出現。爆破壓力是表征波紋管最大抗壓強度的參數。波紋管在整個工作過程中,工作壓身上力遠遠小於爆破壓力,否則波紋管會斷裂損壞。當波紋長度小於或等於外徑時,計算結果接近實際爆破壓力。細長波紋管的實際爆破壓力要低得多。爆破壓力約為允許工作壓力的3~10倍。
                  Therefore, the maximum pressure tolerance under external pressure is higher than that under internal pressure. When both ends of the bellows are fixed, if enough pressure is applied to the cavity, the bellows may be damaged by blasting at the crest. When the internal pressure of bellows is called blasting pressure, bellows begin to appear. Blasting pressure is a parameter to characterize the maximum compressive strength of bellows. During the whole working process, the working pressure of bellows is far less than the blasting pressure, otherwise the bellows will break and damage. When the ripple length is less than or equal to the outer diameter, the calculated results are close to the actual blasting pressure. The actual blasting pressure of slender bellows is much lower. The blasting pressure is about 3 to 10 times of the allowable working pressure.
