金属波纹管具有什么样的特性?

作者: admin    来源:http://www.laobingguandao.com  时间:2019-07-23    人气:
  金属波纹管作为一种柔性耐压管件装置于液体保送系统中,用以补偿管道或机器、设备衔接端的互相位移,吸收振动能量,可以起到减振、消音等作用,具有柔性好、质量轻、耐腐蚀、抗疲倦、耐上下温等多项特性。
  As a flexible pressure-resisting pipe fittings, metal bellows are used in the liquid delivery system to compensate the displacement of the connecting ends of pipes or machines and equipment and absorb vibration energy. They can play the role of vibration reduction and silencing. They have many characteristics, such as good flexibility, light weight, corrosion resistance, fatigue resistance, temperature resistance and so on.
  波纹管在常温时,波形上不发作塑性变形所能接受的大静压力,即为波纹管的大耐压力在普通状况下,波纹管是在一定的压力(内压或外压)下工作的,所以它在整个工作过程中必需接受这个压力而不产生塑性变形。波纹管的耐压力实践上属于波纹管的强度范畴。
  When bellows are at room temperature, the maximum static pressure that can be accepted without plastic deformation occurs in the waveform, that is, the maximum resistance pressure of bellows under normal conditions, bellows work under certain pressure (internal pressure or external pressure), so it must accept this pressure during the whole working process without plastic deformation. In practice, the pressure resistance of bellows belongs to the strength category of bellows.
  计算的关键是应力剖析,也就是剖析波纹管管壁上的应力只需波纹管管壁上大应力点的应力不超越资料的屈从强度,波纹管所受的压力就不会到达其耐压力。同一波纹管在其它工作条件相同时,受外压比受内压时的稳定性要好,所以,受外压作用时的大耐压力比受

  The key of calculation is stress analysis, that is to say, the stress on the wall of bellows can not reach the pressure resistance of bellows only if the stress at the maximum stress point on the wall of bellows does not exceed the yield strength of data. 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.
  内压时高。当波纹管两端固定,假如在其内腔通入足够大的压力时,波纹管波峰处有可能爆破损坏。波纹管开端呈现爆破时波纹管内部的压力值称为爆破压力。爆破压力是表征波纹管大耐压强度的参数。波纹管在整个工作过程中,其工作压力远小于爆破压力,否则波
  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
  纹管将决裂损坏。当波纹长度小于或等于外径时,其计算结果和实践爆破压力很接近;对细长型波纹管其实践爆破压力要低很多。爆破压力大约为允许工作压力的3~10倍。
  The bellows will burst and damage. When the ripple length is less than or equal to the outer diameter, the calculated results are very close to the practical blasting pressure, and the practical blasting pressure of slender bellows is much lower. The blasting pressure is about 3 to 10 times of the allowable working pressure.
