電動扳手的產(chǎn)品名稱型號不同，用途使用范圍也不同。這里介紹定轉(zhuǎn)矩電動扳手，供使用參考。
The product name and model of electric wrench are different, and the scope of use is also different. The constant torque electric wrench is introduced here for reference.
定轉(zhuǎn)矩電動扳手是一種能自動控制轉(zhuǎn)矩的電動扳手。它適用于需要用高強(qiáng)度螺栓連接的橋梁結(jié)構(gòu)、大型鋼塔、鋼結(jié)構(gòu)廠房、冶金設(shè)備的構(gòu)架、大型起重機(jī)架、礦井鋼架等工程中及大型柴油機(jī)、發(fā)電設(shè)備、化工設(shè)備中，要求恒定的夾緊力連接的螺栓也可用定轉(zhuǎn)矩扳手來緊固。
The constant torque electric wrench is a kind of electric wrench that can automatically control the torque. It is applicable to bridge structures, large steel towers, steel structure workshops, metallurgical equipment frames, large crane frames, mine steel frames and other projects that need to be connected with high-strength bolts, and large diesel engines, power generation equipment, and chemical equipment. Bolts that require constant clamping force can also be tightened with a constant torque wrench.
特別在現(xiàn)代橋梁建設(shè)中，定轉(zhuǎn)矩電動扳手是實(shí)現(xiàn)以“栓焊梁”代替“鉚焊梁”的有效工具。這對簡化工地安裝工序、降低建橋成本、減輕勞動強(qiáng)度，從而加速橋梁建設(shè)具有較大的意義。
Especially in modern bridge construction, fixed torque electric wrench is an effective tool to replace "riveted beam" with "bolted beam". This is of great significance to simplify the site installation process, reduce the cost of bridge construction, reduce the labor intensity, and accelerate the bridge construction.

定轉(zhuǎn)矩電動扳手的轉(zhuǎn)矩以電氣裝置來進(jìn)行控制。這種電動扳手具有耗電量少、噪聲小、調(diào)節(jié)靈活、能自動停機(jī)、轉(zhuǎn)矩穩(wěn)定等優(yōu)點(diǎn)。
The torque of fixed torque electric wrench is controlled by electrical device. The electric wrench has the advantages of low power consumption, low noise, flexible adjustment, automatic shutdown and stable torque.
恒剛制造的120kgf·m定轉(zhuǎn)矩電動扳手是一種靜轉(zhuǎn)矩結(jié)構(gòu)的扳手。它可作為高強(qiáng)度螺栓的終擰工具，即把初擰過的螺栓再擰到規(guī)定的力矩。
The 120kgf · m constant torque electric wrench manufactured by Henggang is a kind of wrench with static torque structure. It can be used as a final screwing tool for high-strength bolts, that is, to screw the initially screwed bolts to the specified torque.
電動扳手是裝卸螺紋聯(lián)接件的手持式電動工具，應(yīng)用于汽車、拖拉機(jī)、電機(jī)電器、動力機(jī)械、閥門、水泵、紡織機(jī)械等制造業(yè)的裝配工作中，在化工、水泥預(yù)制件、塑料成型等作業(yè)中則用于生產(chǎn)流程中裝拆真空罐、反應(yīng)釜和水泥模板、帶螺紋塑料件的脫模工作；也可用在鐵道、橋梁、建筑等工程中作水泥軌枕、桁架節(jié)點(diǎn)、角鋼腳手架等結(jié)構(gòu)的安裝、檢修和拆換工作
The electric wrench is a hand-held electric tool for loading and unloading threaded connectors. It is used in the assembly work of automobile, tractor, electric motor, power machinery, valve, water pump, textile machinery and other manufacturing industries. In the chemical industry, cement prefabricated parts, plastic molding and other operations, it is used for the assembly and removal of vacuum tank, reaction kettle, cement template, and demoulding of threaded plastic parts in the production process; It can also be used for the installation, maintenance and replacement of cement sleepers, truss joints, angle steel scaffolds and other structures in railway, bridge, construction and other projects
