電動扭矩扳手的測試方法主要采用簡單的測試設備，通過手動加載實現(xiàn)，存在精度低，功能簡單，效率低的問題。 國外專用的扭矩測試設備可以達到很高的檢測效率，但是昂貴，并且難以維護和擴展。 上述因素嚴重影響了扭矩扳手的生產(chǎn)和檢查。 在現(xiàn)代測控技術中，智能儀表，總線儀表，虛擬儀表等微機測控儀表都充分利用了計算機的軟硬件優(yōu)勢，不僅增強了參數(shù)的測量和處理功能，而且提高了性能。 指標。
The test method of electric torque wrench mainly adopts simple test equipment, which is realized by manual loading, which has the problems of low precision, simple function and low efficiency. Foreign special torque testing equipment can achieve high detection efficiency, but it is expensive and difficult to maintain and expand. These factors seriously affect the production and inspection of torque wrench. In modern measurement and control technology, intelligent instrument, bus instrument, virtual instrument and other microcomputer measurement and control instruments make full use of the advantages of computer software and hardware, which not only enhance the function of parameter measurement and processing, but also improve the performance.

由于尚未建立工業(yè)應用中螺栓緊固的相關標準，并且人力資源相對便宜，因此許多風力渦輪機安裝單元仍保留相對落后的螺栓緊固方法。 傳統(tǒng)的螺栓擰緊方法，即增加錘擊力的扳手，操作簡單，但無法獲得準確可靠的螺栓殘余載荷，嚴重威脅了風力發(fā)電機的運行。 隨著國內(nèi)風力發(fā)電行業(yè)的發(fā)展以及對風機采購和維護投資的增加，對傳統(tǒng)螺栓緊固方法的改革和工具的提供勢在必行。 使用普通的敲擊扳手或扭矩倍增器或液壓扳手進行初始鎖定后，根據(jù)螺栓強度等級和其他條件比較螺栓和螺母尺寸及扭矩值表，然后使用高精度扭矩扳手進行精確的鎖定操作， 可以大大提高風扇的性。

Due to the fact that China has not yet established relevant standards for bolt tightening in industrial applications, and human resources are relatively cheap, many wind turbine installation units still retain relatively backward bolt tightening methods. The traditional bolt tightening method, that is, the wrench with increasing hammering force, is easy to operate, but can not obtain accurate and reliable bolt residual load, which seriously threatens the safe and efficient operation of wind turbine. With the development of domestic wind power industry and the increase of wind turbine procurement and maintenance investment, it is imperative to reform the traditional bolt fastening method and provide advanced tools. After initial locking with ordinary percussion wrench or torque multiplier or hydraulic wrench, the size and torque value table of bolt and nut are compared according to the strength grade of bolt and other conditions, and then the precise locking operation is carried out by using high-precision torque wrench, which can greatly improve the safety of the fan.
電動扭矩扳手作為一種精密設備，風力渦輪機在自然條件差的領域中可以長期運行。 為了確保風力渦輪機的長期有效運行，有必要注意風力渦輪機上的每個細節(jié)，并仔細維護每個組件。 風力渦輪機的外觀主要由四個部分組成：塔架，機艙，輪轂和葉片。 并且這四個部分需要通過螺栓連接。 因此，在風力渦輪機的安裝過程中，螺栓緊固的有效性將直接影響未來風力渦輪機的正常運行和發(fā)電效率，尤其是塔架，機艙轉(zhuǎn)向座椅軸承和 刀片。
As a kind of precision equipment, electric torque wrench can operate for a long time in the field of poor natural conditions. In order to ensure the long-term effective operation of the wind turbine, it is necessary to pay attention to every detail on the wind turbine and carefully maintain each component. The appearance of a wind turbine consists of four parts: Tower, cabin, hub and blade. And these four parts need to be connected by bolts. Therefore, in the process of wind turbine installation, the effectiveness of bolt tightening will directly affect the normal operation and power generation efficiency of future wind turbine, especially tower, cabin, steering seat, bearing and blade.
氣動扭矩扳手可提供精確的扭矩控制，重復精度為±5％，配備傳感器和電磁閥開關，重復精度可達到±2％。 氣動扭矩扳手由于具有體積小，重量輕，單位重量輸出功率高等特點，廣泛用于航空航天，礦山，石油化工，鐵路，建筑等領域，可實現(xiàn)高扭矩輸出，反作用力小，對環(huán)境污染小， 且低廉。 重型車輛的組裝和維護，重型設備的裝卸等廣泛用于產(chǎn)品生產(chǎn)和組裝線，特別是在需要大扭矩的地方。
The pneumatic torque wrench can provide accurate torque control with a repetition accuracy of ± 5%. Equipped with sensors and solenoid valve switches, the repeatability accuracy can reach ± 2%. Pneumatic torque wrench is widely used in aerospace, mining, petrochemical, railway, construction and other fields due to its small size, light weight and high output power per unit weight. It can achieve high torque output, small reaction force, small environmental pollution and low price. The assembly and maintenance of heavy vehicles and the loading and unloading of heavy equipment are widely used in product production and assembly line, especially in places where high torque is required.
