送檢扭力扳手的時間主要取決于你的扭力扳手使用次數(shù)，大部分的扭力扳手在使用過5000次以后就應(yīng)該送檢，而有的廠家聲稱自己的扭力扳手可以經(jīng)過10000次的抗疲勞試驗，這個仁者見仁智者見智。
The time for submitting torque wrenches for inspection mainly depends on the number of times you use them. Most torque wrenches should be submitted for inspection after 5000 times of use. However, some manufacturers claim that their torque wrenches can pass 10000 times of anti fatigue tests. This is a case of different opinions.
事實上這一問題沒有簡單標(biāo)準(zhǔn)答案的原因是因為這取決于扭矩扳手使用的情況。很多如使用頻率、扭矩滿量程百分比設(shè)定、以及使用及儲存的習(xí)慣及環(huán)境等因素都對扭矩扳手造成一定的影響。另一主要的因素是扭矩公差。扭矩與螺栓裝配之間都存在著臨界程度。如：一個直升機組裝公司在每次使用前均校驗他們的扭矩扳手，而汽車工廠則往往對此并沒有如此繁瑣的步驟，也無需如此復(fù)雜的控制程度。
In fact, there is no simple standard answer to this question because it depends on the use of torque wrench. Many factors, such as the frequency of use, the setting of the percentage of full scale torque, the habits of use and storage, and the environment, have a certain impact on the torque wrench. Another major factor is torque tolerance. There is a critical degree between torque and shearbolt assembly. For example, a helicopter assembly company verifies its torque wrench before each use, while an automobile factory often does not have such a complicated procedure or control degree.

那長時間不使用的扭力扳手是不是就能不送檢呢？其實不然，拿預(yù)置扳手舉例，預(yù)置扭力扳手主要靠其內(nèi)部的彈性桿帶動指示器發(fā)出震動、咔噠聲音報警。長時間不使用會式彈性桿老化，所以不是不使用就不用送檢，如果是使用的比較少的朋友可以一年送檢一次。
Can torque wrenches that have not been used for a long time not be submitted for inspection? In fact, take the preset wrench as an example. The preset torque wrench mainly uses its internal elastic rod to drive the indicator to send out a vibration and click sound alarm. The flexible rod is aging if it is not used for a long time, so it is not necessary to submit it for inspection if it is not used for a long time. If it is not used for a long time, friends can submit it for inspection once a year.
如果是使用非常頻繁，送檢地方又特別遠(yuǎn)的地方可以自己購買一臺“扭力扳手檢定儀”來自行標(biāo)定。只要誤差不超工業(yè)安裝標(biāo)準(zhǔn)就行。
If it is used very frequently and the inspection place is far away, you can buy a "torque wrench tester" for calibration. As long as the error does not exceed the industrial installation standard.
