升降貨梯濾清器上蓋開(kāi)裂怎么回事？

升降貨梯http://www.jntr168.com/濾清器上蓋有明顯疲勞斷裂特征說(shuō)明機(jī)油濾清器承受交變載荷，濾清器實(shí)際振動(dòng)加速度已經(jīng)遠(yuǎn)遠(yuǎn)超出了本配件設(shè)計(jì)的承受能力。升降貨梯濾清器上端蓋折彎時(shí)圓弧部位出現(xiàn)了冷作硬化現(xiàn)象，由于冷作硬化部位與周圍硬度差別過(guò)大，造成應(yīng)力集中。升降貨梯濾清器安裝位置不合理造成濾芯振動(dòng)過(guò)大，附加應(yīng)力過(guò)大。
Cargo lifter filter covered with clear description of the fatigue fracture characteristics alternating loads oil filters, filter the actual vibration acceleration has far exceeded the capacity of the accessories design. When the cover appeared on the site of bending arc cargo lifter cleaner cold hardening, work hardening due to the surrounding parts of the hardness difference is too large, resulting in stress concentration. Cargo lifter filter cartridge installation position excessive vibration caused by the irrational, additional stress is too large.

所以應(yīng)該改進(jìn)升降貨梯http://www.jntr168.com/濾清器上端蓋圓弧部位結(jié)構(gòu)，調(diào)整升降貨梯濾清器安裝位置。變更液壓平臺(tái)濾清器固定支架的厚度增加到8mm，增加厚度后測(cè)試其振動(dòng)加速度小于10g，滿足其安裝要求采取以上改進(jìn)措施后，上蓋再未出現(xiàn)開(kāi)裂。
So part of the structure should be improved arc cap on Huoti filter, adjust cargo lifter cleaner installation location. After the change of hydraulic platform to filter mounting bracket thickness 8mm, increasing the thickness of the test the vibration acceleration is less than 10g, the installation requirements to meet their improvements after taking over, cover again uncracked appear.
