    超高压大功率清洗机的安全性非常重要,尤其是泵缸体,它是一个超高压容器,对于管路任何裂缝和螺纹脱节都会导致危险,而对于超高压大功率清洗机,气动安全阀或爆破膜安全阀将是最后一道防线。因此,各大型零部件的选材、无损检测、结构设计、加工与热处理直到组装试验,每一步都要很严格。
     
    另外,对承压缸体的自增强处理工艺很关键,我们一般是以两倍工作压力使其内壁产生压缩预应力,产生径向扩大的残余变形。这样,在工作承压后,应力分布比较均匀,全部应力维持在弹性范围内,弹性?#24615;?#33021;力增大,提高缸体疲劳寿命,设计原则是选择材料和工艺给出最佳自增强压力和最佳自增强度。(图/文www.bqhi.tw)

    Safety of ultra high voltage power cleaning machine is very important, especially the pump cylinder, it is a super high pressure vessel, pipe for any cracks and thread disconnection will cause danger, but for ultra high voltage power cleaning machine, pneumatic safety valve or safety valve blasting film will be the last line of defense. Therefore, the large parts of the material, nondestructive detection, structure design, machining and heat treatment until the assembly test, every step is very strict.
    In addition, self enhancement treatment process is the key to the bearing block, we are generally based on two times the working pressure to the inner wall of the compression stress, residual radial expansion deformation. So, in the working pressure, the stress distribution is more uniform, all the stresses in elastic range, increase the elastic bearing capacity, improve the cylinder fatigue life, the principle of design is the selection of materials and process gives the optimum autofrettage pressure and best self increasing strength.
