leak hunting 檢漏,測漏。

leak-proof

Incondition of surface anti - corrision and insulation coat of metal and tiny hole of steel where resistance and crack is very small , when supplying a high voltage , gas crack will be punctured and electric spark discharging will occur , now send a pulse signal to the alarming circuit the alarmer can send out sound and light to alarm . we can do leak hunting on the coating according to this principle 金屬表面絕緣防腐層過薄、漏鐵及漏電微孔處的電阻值和氣隙密度都很小,當有高壓經過時就形成氣隙擊穿而產生火花放電,給報警電路產生一個脈沖信號,報警器發出聲光報警,根據這一原理達到防腐層檢漏目的。

First , rubber sponge balls are mainly synthesized with silicone rubber . in addition , tubular membrane is dominatingly made of polyvinylidene fluoride ( pvdf ) with the integrated production technology and the membrane is tested with self - made leak hunting device 首先,以硅橡膠為主要原料合成生產了海綿橡膠球;另外,以聚偏氟乙烯( pvdf )為主要原料用管式膜一體化技術生產了管式膜,并通過自行設計的檢漏裝置對管式膜進行檢測。

After analyzing the merits and shortcomings of the current methods for leak hunting of municipal water supply network and inducing the reasons that cause the pipe leakage , this thesis pointed out that the water supply network should be evaluated synthetically by means of reliability theory 本文分析了現有給水管網檢漏方法的優缺點,在歸納了導致管道漏損的各種原因的基礎上,指出應該利用可靠度理論對管網進行綜合評價。

Finally , based on the types of all load , using matlab , the reliability programs are compiled to calculate the reliability index under different design and different load combination . the results can be used to evaluate the relatively safety , and direct the leak hunting 最后,基于所得出的各種荷載的分布狀況,利用matlab環境編制可靠度計算程序,利用該程序計算在不同設計情況下、不同荷載組合情況下的管壁強度可靠度指標。
