The test method of electric torque wrench mainly adopts simple test equipment, which is realized by manual loading, and 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.

上述因素嚴(yán)重影響了扭矩扳手的生產(chǎn)和檢查。在現(xiàn)代測控技術(shù)中，智能儀表，總線儀表，虛擬儀表等微機(jī)測控儀表都充分利用了計(jì)算機(jī)的軟硬件優(yōu)勢，不僅增強(qiáng)了參數(shù)的測量和處理功能，而且提高了性能。指標(biāo)。

The above factors seriously affect the production and inspection of torque wrench. In modern measurement and control technology, intelligent instruments, bus instruments, virtual instruments and other microcomputer measurement and control instruments make full use of the advantages of computer software and hardware, which not only enhances the function of parameter measurement and processing, but also improves the
performance. Indicators.

電動(dòng)扭矩扳手作為一種精密設(shè)備，風(fēng)力渦輪機(jī)在自然條件差的領(lǐng)域中可以長期運(yùn)行。為了確保風(fēng)力渦輪機(jī)的長期有用運(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)組件。

As a kind of precision equipment, electric torque wrench can be used in the field of poor natural conditions for a long time. In order to ensure the long-term useful operation of the wind turbine, it is necessary to pay attention to every detail on the wind turbine and carefully maintain each component.

風(fēng)力渦輪機(jī)的外觀主要由四個(gè)部分組成：塔架，機(jī)艙，輪轂和葉片。并且這四個(gè)部分需要通過螺栓連接。因此，在風(fēng)力渦輪機(jī)的安裝過程中，螺栓緊固的有用性將直接影響未來風(fēng)力渦輪機(jī)的正常運(yùn)行和發(fā)電效率，尤其是塔架，機(jī)艙轉(zhuǎn)向座椅軸承和刀片。

The appearance of the wind turbine is mainly composed of four parts: Tower, cabin, hub and blade. And these four parts need to be connected by bolts. Therefore, in the installation process of wind turbines, the usefulness of bolt tightening will directly affect the normal operation and power generation efficiency of future wind turbines, especially the tower, engine room, steering seat, bearing and blade.

氣動(dòng)扭矩扳手可提供精確的扭矩控制，重復(fù)精度為±5％，配備傳感器和電磁閥開關(guān)，重復(fù)精度可達(dá)到±2％。氣動(dòng)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(diǎn)，廣泛用于礦山，石油化工，鐵路，建筑等領(lǐng)域，可實(shí)現(xiàn)高扭矩輸出，反作用力小，對(duì)環(huán)境污染小，且低廉。重型車輛的組裝和維護(hù)，重型設(shè)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 precise torque control with a repeat accuracy of 1 ± 5%, equipped with sensor and solenoid valve switch, the repetition accuracy can be achieved ± 2％。 Pneumatic torque wrench is widely used in mining, petrochemical, railway, construction and other fields because of its small volume, light weight and high output power per unit weight. It can achieve high torque output, small reaction force, small environmental pollution and low price. Assembly and maintenance of heavy vehicles, loading and unloading of heavy equipment are widely used in product production and assembly lines, especially in places where large torque is required.
