電動(dòng)扭剪扳手主要用于一次擰緊螺栓。它的使用非常簡單，即將電源開關(guān)拉到螺栓上。電動(dòng)剪切扳手主要用于緊固剪切型高強(qiáng)度螺栓。用于將電源開關(guān)拉向螺栓，直到剪切型高強(qiáng)度螺栓的箱頭斷裂。扭矩剪切扳手可用于初始擰緊和更終擰緊。用于在擰緊螺栓之前調(diào)整扭矩。扭矩剪切扳手也是一種恒定電動(dòng)扭剪扳手。用于先調(diào)整旋轉(zhuǎn)角度，然后擰緊螺栓。電動(dòng)角度扳手是專門用于緊固鋼架角度處螺栓的電動(dòng)扳手，其用途與電動(dòng)扭矩剪切扳手的原理相同。
Electric torque wrench is mainly used to tighten bolts in one go. Its use is very simple, that is, pull the power switch onto the bolt. Electric shear wrenches are mainly used to tighten shear type high-strength bolts. Used to pull the power switch towards the bolt until the box head of the shear type high-strength bolt breaks. Torque shear wrenches can be used for initial and final tightening. Used to adjust torque before tightening bolts. The torque shearing wrench is also a constant electric torque shearing wrench. Used to adjust the rotation angle first and then tighten the bolts. Electric angle wrench is an electric wrench specifically used to tighten bolts at the angle of a steel frame, and its purpose is the same as that of an electric torque shearing wrench.
剪切扳手主要用于緊固剪切型高強(qiáng)度螺栓。其目的是破壞剪切型高強(qiáng)度螺栓的梅花頭。工作時(shí)，將扳手頭與螺栓頭對(duì)齊，拉動(dòng)開關(guān)開始工作。幾秒鐘后，螺栓箱頭會(huì)斷裂，然后拔出扳手拉動(dòng)扳機(jī)彈出箱頭，這就是工作的結(jié)束。一般情況下，應(yīng)先擰緊高強(qiáng)度螺栓，然后再擰緊，每一步都需要嚴(yán)格的扭矩要求。固定電動(dòng)扭剪扳手要用于大六角高強(qiáng)度螺栓的初始和更終擰緊。因此，各種電動(dòng)扳手設(shè)計(jì)用于各種緊固需求。電動(dòng)電動(dòng)扭剪扳手的測(cè)試方法主要采用簡單的測(cè)試設(shè)備，通過手動(dòng)加載實(shí)現(xiàn)。存在精度低、功能簡單、效率低等問題。國外的專用扭矩測(cè)試設(shè)備可以實(shí)現(xiàn)較高的測(cè)試效率，但成本昂貴，難以維護(hù)和擴(kuò)展。上述因素嚴(yán)重影響了電動(dòng)扭剪扳手的生產(chǎn)和檢驗(yàn)。在現(xiàn)代測(cè)控技術(shù)中，智能儀表、總線儀表、虛擬儀表等微機(jī)測(cè)控儀表充分利用計(jì)算機(jī)軟硬件的優(yōu)勢(shì)，不僅增強(qiáng)了參數(shù)的測(cè)量和處理功能，而且提高了性能。指標(biāo)。
Shear wrenches are mainly used to tighten shear type high-strength bolts. Its purpose is to destroy the plum blossom head of shear type high-strength bolts. When working, align the wrench head with the bolt head and pull the switch to start working. After a few seconds, the bolt box head will break, and then pull out the wrench to pull the trigger and eject the box head, which is the end of the work. In general, high-strength bolts should be tightened first and then tightened, with strict torque requirements required for each step. The fixed electric torque wrench should be used for the initial and final tightening of large hexagonal high-strength bolts. Therefore, various electric wrenches are designed for various tightening needs. The testing method for electric electric torsion shear wrenches mainly uses simple testing equipment and is achieved through manual loading. There are issues such as low accuracy, simple functionality, and low efficiency. Foreign specialized torque testing equipment can achieve high testing efficiency, but it is expensive and difficult to maintain and expand. The above factors have seriously affected the production and inspection of electric torsion shear wrenches. In modern measurement and control technology, microcomputer measurement and control instruments such as intelligent instruments, bus instruments, and virtual instruments fully utilize the advantages of computer software and hardware, not only enhancing the measurement and processing functions of parameters, but also improving performance.

由于中國尚未建立工業(yè)應(yīng)用中螺栓緊固的相關(guān)標(biāo)準(zhǔn)，且人力資源相對(duì)便宜，許多風(fēng)力渦輪機(jī)安裝單元仍然保留相對(duì)落后的螺栓緊固方法。傳統(tǒng)的螺栓緊固方法，即錘擊力增加的扳手，操作簡單，但無法獲得準(zhǔn)確可靠的螺栓殘余載荷，嚴(yán)重威脅風(fēng)力發(fā)電機(jī)的安全運(yùn)行。
Due to the lack of established standards for bolt tightening in industrial applications in China and the relatively cheap human resources, many wind turbine installation units still retain relatively outdated bolt tightening methods. The traditional bolt tightening method, which is a wrench with increased hammering force, is simple to operate, but cannot obtain accurate and reliable bolt residual load, seriously threatening the safe operation of wind turbines.
用普通沖擊扳手或扭矩倍增器或液壓扳手初次鎖定后，根據(jù)螺栓強(qiáng)度等級(jí)等條件，比較螺栓螺母尺寸和扭矩值表，然后使用高精度電動(dòng)扭剪扳手進(jìn)行準(zhǔn)確鎖定操作，可大大提高風(fēng)機(jī)的安全性。電動(dòng)電動(dòng)扭剪扳手作為一種精密設(shè)備，可用于風(fēng)力發(fā)電機(jī)在惡劣自然條件下的長期運(yùn)行。為了確保風(fēng)力渦輪機(jī)的長期有效運(yùn)行，有必要注意風(fēng)力渦輪機(jī)上的每個(gè)細(xì)節(jié)，并仔細(xì)維護(hù)每個(gè)部件。
After the initial locking with an ordinary impact wrench, torque multiplier, or hydraulic wrench, compare the bolt and nut dimensions and torque value table based on conditions such as bolt strength grade, and then use a high-precision electric torsion shear wrench for precise locking operation, which can greatly improve the safety of the fan. As a precision equipment, electric electric torque wrench can be used for long-term operation of wind turbines under harsh natural conditions. In order to ensure the long-term effective operation of wind turbines, it is necessary to pay attention to every detail on the wind turbine and carefully maintain each component.
