扭力扳手的選擇
Selection of torque wrench
怎么來選擇好的扭了扳手，根據扭力值的不同，請選擇不同的扭力扳手，我們建議用戶在購買時選擇扭力值區間在扭力扳手的中間部位，即20%-80%扭力區間，例如我們在用100Nm的扭力去鎖緊螺絲時候，我們建議選擇HAZET的5122-3CT扭矩范圍是40-200Nm，這樣里面彈簧結構不會經常觸即臨界點，更好的保護扭力扳手，并能長期使用。
How to choose a good torque wrench? According to the different torque values, please choose different torque wrenches. We recommend that users choose the torque value range in the middle of the torque wrench when purchasing, that is, the 20% -80% torque range. For example, when we use 100Nm of torque to lock the screw, we recommend choosing HAZET's 5122-3CT torque range of 40-200Nm, so that the spring structure inside will not frequently touch the critical point, better protect the torque wrench, and can be used for a long time.
1. 為什么要選用扭力扳手來鎖螺絲，而不是拆螺絲
Why choose a torque wrench to lock screws instead of removing them
扭力扳手與其說是一種工具，更適合說是一種量具，一般的螺絲我們可以用棘輪扳手或者普通扳手來拆裝即可，使用的力是根據個人的力量大小決定螺絲的鎖緊程度，而機械設備等比較重要的部位螺絲，需要一定的扭力值才能達到適合，即不會損壞螺絲又保證使用需要；拆卸螺絲的時候，會有瞬間強力，即使新裝的螺絲，然后拆卸下來，這個松動力量遠大于剛安裝的扭力，很容易造成扭力扳手的損壞。
A torque wrench is not so much a tool as a measuring tool. Generally, we can use a ratchet wrench or a regular wrench to disassemble and assemble screws. The force used depends on the individual's strength to determine the degree of locking of the screw. However, screws in important parts such as mechanical equipment require a certain torque value to achieve the most suitable value, which will not damage the screw and ensure the use needs; When disassembling screws, there will be an instant force. Even if a new screw is installed and then removed, the loosening force is much greater than the maximum torque of the newly installed one, which can easily cause damage to the torque wrench.
2. 扭力扳手精準再校正
2. Precise recalibration of torque wrench
扭力扳手與汽車都是一樣，行駛一定里程，使用一段時間后，都需要保養，扭力扳手在使用達到規定次數或者時間后，一般是5000次或者半年，需要進行扭力精準再校正，需要由人員使用設備調節校正，延長扭力扳手的壽命就必須要注意：每次用完后將扭力值歸零，以免彈簧長期受壓，彈性疲乏，導致扭力扳手壽命縮短。
A torque wrench is the same as a car. After driving a certain mileage and using it for a period of time, it needs maintenance. After using the torque wrench for a specified number of times or time, it is usually 5000 times or half a year, and it needs to be calibrated accurately. It needs to be adjusted and calibrated by professionals using professional equipment. To extend the service life of the torque wrench, it is necessary to pay attention to resetting the torque value to zero after each use, in order to avoid long-term compression of the spring, fatigue of the elasticity, and shorten the service life of the torque wrench.
扭力扳手常規維護
Routine maintenance of torque wrench
若達到預設扭力，又繼續施壓時會造成工作物受到傷害。
If the preset torque is reached and pressure is continued, it will cause damage to the workpiece.
設定扭力值之前，需檢查扭力扳手是在鎖定或者解鎖 也就是LOCK OR UNLOCK的狀態。
Before setting the torque value, it is necessary to check whether the torque wrench is locked or unlocked, that is, in the LOCK or UNLOCK state.
一般來說扭力扳手在出廠時，已經校正及測試，不同款式精準度不同，任意扭力值點分別為±4%，±3%，±1%，這是高精確測量儀器，因此僅有人員才可作維修，切勿浸泡在任何液體中，否則會影響其內部的潤滑。
Generally speaking, torque wrenches are calibrated and tested before leaving the factory. The accuracy varies depending on the style, with any torque value point being ± 4%, ± 3%, ± 1%. This is a high-precision measuring instrument, so only professionals can perform repairs. Do not immerse them in any liquid, otherwise it will affect their internal lubrication.
