What's the difference between a pneumatic wrench and an electric wrench?

Abstract: Pneumatic wrench and electric wrench are two commonly used wrenches, and their power sources are mainly different. One is driven by compressed air, and the other is driven by electricity. In addition, there are some differences between them in principle, use, economy and torque. Comparatively speaking, the torque of pneumatic wrench is greater, but electric wrench also has the advantages of high precision, long life and low noise. How to choose depends mainly on actual needs. Let's first understand the difference between some pneumatic wrenches and electric wrenches. 1. What's the difference between a pneumatic wrench and an electric wrench?

The traditional wrench is manual. With the development of science and technology, pneumatic wrenches and electric wrenches were gradually invented. Pneumatic wrench and electric wrench are both wrenches, but there are some differences between them. The main differences between pneumatic wrenches and electric wrenches are:

1, power source is different, pneumatic wrench uses compressed air provided by air compressor as power source, and electric wrench uses electricity as power source.

2. In addition, the principles of the two wrenches are different. In the aspect of reciprocating operation, the pneumatic wrench adopts piston movement, while the electric wrench is realized by cam conversion.

3. It also has different uses. Compared with electric wrenches, pneumatic wrenches have no heating and overload faults, and are more suitable for long-term work without heating. The electric wrench is relatively heavy, which requires the working environment and is not suitable for working for a long time.

4. Economically, the initial investment of pneumatic torque wrench needs to be equipped with pneumatic pipeline equipment, but the cost of long-term use is low in terms of energy consumption and tool maintenance; The initial investment of electric wrench is low, but the energy consumption is high after long-term use, and the cost of tool maintenance and replacement is also high.

2. Which is more torque, pneumatic wrench or electric wrench?

When using a wrench, you need to consider the torque of the wrench. If the torque is not enough, it can't be used for some heavy equipment. So which torque is greater, the pneumatic wrench or the electric wrench?

The torque of the pneumatic wrench is mainly related to the air intake and can be adjusted; The torque of electric wrench is mainly related to its power. Generally speaking, the torque of pneumatic wrench is relatively large, about 900- 1200N-m (N-m), while that of electric wrench is generally 200-300 n-m. ..

3. Pneumatic wrench or electric wrench?

I'm not sure which is better, pneumatic wrench or electric wrench. Both have their own advantages:

1. The pneumatic wrench has the advantages of simple speed regulation and output power adjustment, more choices in the speed range, large torque, no heating and overload faults, and can work in various harsh or harsh environments.

2. The advantages of electric wrench are high precision, long service life, safety and reliability, low price and low noise.

So which one to choose depends on the use requirements and the actual situation.
