Overview of a pneumatic torque wrench

A Pneumatic Torque Wrench is a type of torque wrench that operates using a high-pressure air pump.

It is equipped with three or more layers of epicyclic gears, which are driven by one or two powerful air motors.

The torque output of the wrench is controlled by adjusting the gas pressure and is designed to meet specific torque requirements. 

Each pneumatic torque wrench comes with a dedicated air-torque comparison chart and calibration report,

ensuring accurate torque measurement. Additionally, for enhanced accuracy, the wrench can be equipped with a torque sensor.

This sensor further improves the precision of the output torque. 

Pneumatic torque wrenches offer several advantages that make them a popular choice in various industries.

Here are some key advantages of pneumatic torque wrenches:

1. High Torque Output: Pneumatic torque wrenches are capable of delivering high torque output,

making them suitable for applications that require significant tightening or loosening force.

They can handle heavy-duty tasks that conventional torque wrenches may struggle with.

2. Speed and Efficiency: Pneumatic torque wrenches operate at high speeds, allowing for quick and efficient

tightening or loosening of bolts and fasteners. This helps to increase productivity and reduce overall task completion time.

3. Versatility: Pneumatic torque wrenches are versatile tools that can be used in a wide

range of applications across different industries. They are suitable for various tasks, 

including automotive assembly, construction, manufacturing, maintenance, and more.

4. Precise Torque Control: Adjustable pneumatic torque wrenches allow for precise torque control. 

They can be set to a specific torque value, ensuring accurate and consistent tightening or loosening of bolts.

This helps prevent under-tightening or over-tightening, reducing the risk of damage or failure.

5. Durability and Reliability: Pneumatic torque wrenches are built to withstand heavy-duty usage and harsh working conditions. 

They are designed for durability and can handle demanding applications. 

With proper maintenance, they offer long-term reliability and consistent performance.

Pneumatic torque wrenches are generally categorized into two types: conventional and adjustable. 

The conventional type does not allow for torque adjustment, while the adjustable type, 

such as pneumatic torque wrenches, can be set to a specific torque value.

This makes them more versatile and suitable for a wider range of applications.

Application

The stable and continuous torque output of the pneumatic torque wrench makes 

it widely suitable for torque control of various nut and nutless connections.

With nuts:

Pneumatic torque wrenches are suitable for tightening or removing large nuts.

Here are some of its applications：

Truck tire bolts, buses and large machinery

Building steel frame structure

Injection head on plastic injection molding machine

heat exchanger

Mining Equipment Maintenance

Without nut:

When continuous high torque is required, pneumatic torque wrenches can be used if a source of energy is available.

Typical occasions include:

Reel adjustment of steel mills and paper mills

Pneumatic valve

Heavy-Duty Automotive Applications

Assembly and Disassembly of Heavy Equipment

Maintenance and Repair of Power Generation Equipment
