What are the differences between electric wrench, pneumatic wrench and torque wrench?
Widely used in many industries, such as automotive repair, heavy equipment maintenance, product assembly (usually called "pulse tool" and designed for precise torque output), major construction projects, installation of steel wire Lo sets, and high torque output in any other part of the need. Torque wrench torque wrench torque wrench or also called or torque wrench, torque force and distance is the product of the need to control the torque exerted on the fastening screw bolt and nut threaded fasteners, to ensure that the thread fastening torque is too large and does not damage due to threads, so use the torque wrench to operate.
The first set a torque limit when the applied torque reaches the set value, the wrench will be issued a "Kata" sound or a wrench bend at the joint point of this representative has not the fastening force. The pneumatic plate hand can be sized at each of the standard ratchet socket drives, from small 1/4, drive tools, group loading and disassembly to 3.5. The pneumatic wrench is not suitable for fastening the device body and is used for fastening the installation parts of ceramics and plastics. The working principle of torque wrench torque wrench (spanner) issued a sound principle Kata is very simple, can be divided into the following steps: 1, torque wrench to understand the issue of "Kata" sound after the prompt you has reached the requirements of the torque value; a torque wrench 2, "Kata" is produced by itself the torque release structure, its structure is divided into pressure spring, torque release joint, torque rod structure composed of three to 3, first in the torque wrench to set the desired torque value (set by the spring on the push rod to release joint torque pressure), locking torque wrench to tighten the bolts. When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), it will produce an instantaneous disconnection effect. In effect generated from a sudden joint percussion, a wrench of the metal shell "Kata" sound. This confirms the reminder of the torque value (in fact, as in our elbow joint, which is bent at 15 degrees, placed in the iron tube and then touched by a straight line.
The pneumatic hand wrench, also known as the ratchet wheel, hand and power tool assembly, is primarily a tool for providing high torque output with minimal consumption. It allows a mass object to rotate at a constant speed through a constant power source, and then instantaneously hits the output shaft so that a relatively large torque output can be obtained. Compressed air is the most common source of power, but there are also electric or hydraulic ones.
An electric wrench is a wrench powered by a power source or battery. It is a tool for tightening bolts. Mainly used in the steel structure installation industry, special installation of steel structural high-strength bolt, high strength bolt is used to connect the steel structure contact, usually with bolt group way.
