Electric wrench is a wrench driven by "electricity". It refers to an electric tool for tightening and removing bolts and nuts. It is a tool for tightening high-strength bolts. It is used for the initial tightening and final tightening of large hexagon head high-strength bolts in the construction of steel structure bridges, factory buildings, chemical industry and power generation equipment, and the initial tightening of torsional shear type high-strength bolts, as well as the occasions where there are strict requirements on the torque or axial force of bolt fasteners.

从结构来说，必威西汉姆联官网g1线路有安全离合器式和冲击式两种结构型式。

In terms of structure, the electric wrench has two types of structure: safety clutch type and impact type.

从电源来分，必威西汉姆联官网g1线路可分为：带电池的必威西汉姆联官网g1线路、插220V电源的必威西汉姆联官网g1线路。

In terms of power supply, electric wrenches can be divided into: electric wrenches with batteries and electric wrenches with 220V power supply.

其中带电池的必威西汉姆联官网g1线路体积小重量轻、使用方便，但是扭矩小，一般用来打普通螺丝。而插220V电源的必威西汉姆联官网g1线路相对来说比带电池的必威西汉姆联官网g1线路要重，还大，主要是扭矩大，可以紧固高强螺栓。以下几种必威西汉姆联官网g1线路都是插电源的必威西汉姆联官网g1线路。

The electric wrench with battery is small in size and light in weight, convenient in use, but small in torque, and generally used to make ordinary screws. The electric wrench with 220V power supply is relatively heavier and larger than the electric wrench with battery, mainly because of its large torque, which can fasten high-strength bolts. The following electric wrenches are all electric wrenches plugged into the power supply.

冲击必威西汉姆联官网g1线路就是常说的普通必威西汉姆联官网g1线路，主要是初紧螺栓的,它的使用很简单,就是对准螺栓扳动电源开关就行。

The impact electric wrench is often called an ordinary electric wrench. It is mainly used to tighten the bolts for the first time. It is very simple to use, that is, pull the power switch against the bolt.

扭剪必威西汉姆联官网g1线路主要是终紧扭剪型高强螺栓的,它的使用就是用扳手套筒对准螺栓梅花头，扳动电源开关,直到把扭剪型高强螺栓的梅花头打断为止。常见的扭剪必威西汉姆联官网g1线路是枪式的，也有角向的。

The electric wrench for torsional shear is mainly used to tighten the torsional shear type high-strength bolt. It is used to align the wrench socket with the bolt box head and turn the power switch until the box head of the torsional shear type high-strength bolt is broken. The common electric wrench for twist shear is gun type and also angular.

定扭矩必威西汉姆联官网g1线路既可初紧又可终紧,它的使用是先调节扭矩,再紧固螺栓。常见的定扭矩必威西汉姆联官网g1线路也是枪式的，也有角向的。

The fixed torque electric wrench can be used for initial tightening and final tightening. It is used to adjust the torque first, and then tighten the bolts. The common constant torque electric wrench is also gun type and angular.

转角法必威西汉姆联官网g1线路主要也属于定扭矩扳手的一种,它的使用是先调节旋转度数,再紧固螺栓。

The angle method electric wrench is also a kind of constant torque wrench. It is used to adjust the rotation degree first, and then tighten the bolts.

角向必威西汉姆联官网g1线路是一种专门紧固钢架夹角部位螺栓的必威西汉姆联官网g1线路,它的使用和其他前田必威西汉姆联官网g1线路原理一样。

The angle electric wrench is an electric wrench specially used to fasten the bolts at the angle of the steel frame. Its use principle is the same as that of other Maeda electric wrenches.

超大扭矩必威西汉姆联官网g1线路，一般是带倍增器，也有本身就达到10000Nm以上的定扭矩必威西汉姆联官网g1线路扳手。

The super torque electric wrench is generally equipped with a multiplier, and there are also constant torque electric wrench wrenches that can reach 10000Nm or more.

数显必威西汉姆联官网g1线路属于定扭矩必威西汉姆联官网g1线路，本身带着显示仪，是可以直接读取扭矩值数据的必威西汉姆联官网g1线路。

Digital display electric wrench belongs to constant torque electric wrench, with a display, which can directly read torque data.

施工现场安全注意事项：

Safety precautions on construction site:

1)在接通电源前，需要检查开关处于断开状态才能插入。

1) Before turning on the power, check that the switch is disconnected before inserting it.

2)确认现场所接电源与必威西汉姆联官网g1线路所需要电压是否相符，是否接有漏电保护器。

2) Confirm whether the on-site power supply is consistent with the voltage required by the electric wrench, and whether there is a leakage protector connected.

3)根据螺母大小选择匹配的套筒，并妥善安装。

3) Select the matching sleeve according to the nut size and install it properly.

4)电压过高过低均不宜使用。

4) If the voltage is too high or too low, it should not be used.

5)不要将简体当做锤击工具使用。

5) Do not use Simplified Chinese as a hammer tool.

6)不要在手摇杆上增加套杆或撬棒后加力。

6) Do not apply force after adding a sleeve or crowbar to the hand crank.

7)必威西汉姆联官网g1线路的金属外壳需要可靠接地。

7) The metal shell of the electric wrench shall be reliably grounded.

8)检查必威西汉姆联官网g1线路机身安装螺钉紧固情况，如果发现螺钉松了，需要立即重新扭紧。

8) Check the fastening of the mounting screws on the body of the electric wrench. If the screws are found to be loose, retighten them immediately.

9)检查手持必威西汉姆联官网g1线路两侧手柄是否完好，安装是否牢固。

9) Check whether the handles on both sides of the hand-held electric wrench are intact and firmly installed.

10)站在梯子上工作或高处作业应做好防止高处坠落措施。

10) Measures shall be taken to prevent falling from heights when working on ladders or at heights.

11)如果作业场所在远离电源的地点，需延伸线缆时，需要使用容量足够、安装合格的延伸线缆。

11) If the work place is far away from the power supply, the extension cable with sufficient capacity and qualified installation shall be used.

柴油发电机组一般运行500h后应更换机油一次，但有时候未到更换期，或还没用多长时间就出现机油变稀、杂质增多现象，无法继续使用。     柴油发电机组机油为何会变质过快     ①、机油牌号不对、质量达不到要求，一般增压和标定转速大于2000r/min的柴油发电机应选用CC级以上的机油；     ②、柴油机发电机技术状况不好，窜气、窜油、配合间隙过大或油温过高；     ③、柴油机发电机经常在低温、低负荷、低速下运转，活塞变形量不够，燃烧不完全，有柴油沿缸 壁进入油底壳使机油稀释变质；     ④、废气进入油底壳凝结成水分和酸性物质，使机油变质；     ⑤、机油滤芯脏，未经滤清的脏机油进入润滑部位，加速了零件的磨损。     ⑥、滤芯密封圈破裂而发生内漏，一部分机油未经滤芯而直接通过滤清器而造成机油变质。

Generally, the engine oil of the diesel generator set should be replaced once after 500h of operation, but sometimes the replacement period is not reached, or the engine oil has become thinner and impurities have increased within a short period of time, which makes it impossible to continue to use. Why the engine oil of the diesel generator set deteriorates too fast ①. The engine oil is of the wrong brand and the quality does not meet the requirements. Generally, the diesel generator with supercharging and rated speed greater than 2000r/min should use the engine oil above CC level; ② The diesel generator is in poor technical condition, with gas and oil leakage, too large fitting clearance or too high oil temperature; ③ The diesel engine generator often operates at low temperature, low load and low speed. The piston deformation is not enough and the combustion is incomplete. Diesel enters the oil pan along the cylinder wall to dilute and deteriorate the oil; ④ Waste gas enters the oil pan and condenses into water and acid substances, which will deteriorate the engine oil; ⑤ The oil filter element is dirty, and the unfiltered dirty oil enters the lubricating part, which accelerates the wear of parts. ⑥ . The sealing ring of the filter element is broken and internal leakage occurs. Some engine oil directly passes through the filter element without passing through the filter element, causing deterioration of the engine oil.
