一、扭力扳手有哪些種類
1、 What kinds of torque wrenches are there
1、按動(dòng)力源可分為：電動(dòng)扭力扳手、氣動(dòng)扭力扳手、液壓扭力扳手及手動(dòng)扭力扳手;
1. According to the power source, it can be divided into: electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench;
2、按測(cè)量原理可分為：預(yù)置式、示值式、指針式、數(shù)字式、電子式以及定值式扳手。
2. According to the measurement principle, it can be divided into: preset wrench, indicating wrench, pointer wrench, digital wrench, electronic wrench and fixed value wrench.
二、預(yù)置式扭力扳手的特點(diǎn)
2、 Characteristics of preset torque wrench
預(yù)置式扭力扳手具有預(yù)設(shè)扭矩?cái)?shù)據(jù)和聲響裝配。當(dāng)緊固件的擰緊扭矩達(dá)到預(yù)設(shè)數(shù)據(jù)時(shí)，能自動(dòng)拍發(fā)訊號(hào)"卡嗒"(click)的一聲，同時(shí)伴有明顯的手撫摸時(shí)的感覺振動(dòng)，提示工作完成。解除有效用力后，扳手各相關(guān)零件能自動(dòng)復(fù)位 。
Preset torque wrench has preset torque data and sound assembly. When the tightening torque of the fastener reaches the preset data, it can automatically send a signal "click", accompanied by obvious sensory vibration when touching, indicating that the work is completed. After releasing the effective force, all relevant parts of the wrench can be reset automatically.
可手動(dòng)精確設(shè)定扭矩值;手柄人體工程學(xué)優(yōu)化設(shè)計(jì)，握持舒適，大大降低高強(qiáng)度操作時(shí)產(chǎn)生的疲勞感。
The torque value can be accurately set manually; The ergonomic optimization design of the handle makes it comfortable to hold, greatly reducing the fatigue caused by high-intensity operation.
