What is a pneumatic torque wrench and its application

A pneumatic torque wrench is a torque wrench powered by a high-pressure air pump. A torque multiplier with three or more epicyclic gears driven by one or two powerful air motors. Torque is controlled by adjusting gas pressure. To allow for specific torque demand settings, each tool is equipped with a dedicated gas-to-torque comparison chart and calibration report. And for further application, the pneumatic torque wrench can be equipped with a torque sensor at the same time, and the output torque is more accurate. The air supply can be switched off manually or automatically using a suitable circuit system after the required torque has been achieved.
In the production line or when a large number of nuts must be locked, choosing a pneumatic torque wrench with a power device can save a lot of work time and manpower, and effectively improve work efficiency. The operation of the pneumatic torque wrench is quiet - less than 85dB(A), absolutely no impact, reducing damage to 1/2 impact wrench factory the tool, socket and locked objects, these two factors can make the tool user comfortable and reduce Fatigue, improve safety, torque up to 300,000N.m.
The pneumatic torque wrench provides precise torque control--with a repeatability of ±5%, equipped with a sensor + solenoid valve switch, the repeatability can reach ±2%. Pneumatic torque wrenches are widely used in aerospace, mining, petrochemical, railway, construction, Heavy-duty vehicle assembly and maintenance, heavy-duty equipment loading and unloading and many other fields, especially in product production assembly lines, are widely used, especially where high torque is required.
The stable and continuous torque output of the pneumatic torque wrench makes it widely suitable for torque control in various nut and nutless connections. Where there is a nut: Pneumatic torque wrench is suitable for locking or disassembling the nut. Here are some of its applications:
◆Truck tire bolts, buses and large machinery; ◆Construction steel frame structure;
◆High pressure connections, such as: pipelines, boiling water pumps and pressure conduits;
◆The nut of the engine head;
◆Injection head on plastic injection molding machine;
◆ heat exchanger;
◆Heavy vehicle products, such as: nuts for car chassis and suspension devices.
Without nut:
Pneumatic torque wrenches can be used when a source of energy is available when continuous high torque is required. Typical occasions include:
◆Operation of ball valve;
◆Large trucks and overhead mobile cranes;
◆In construction, bearing on large diesel engines; ◆Welding test applied to test torque;
◆Reel adjustment in steel mills and paper mills;
◆Pneumatic valve.
