6mm Air Impact Wrench
● Durable and easy to maintain:Heavy industry manufacturing, industrial-grade quality, simple structure, low failure rate, convenient for maintenance and upkeep.
● Compact structure, labor-saving operation:The overall weight is approximately 0.96kg, with a compact structure (body length 152mm). It is not only flexible for handheld operation, but its aerodynamic design also effectively enhances safety.
● Low energy consumption and cost-effective: The air consumption is relatively low (5L/s), with a working pressure of 0.63MPa, making it energy-efficient and helpful in reducing operating costs.
Product introduction
The 6mm Air Impact Wrench is a modern hand tool, widely applicable for tightening and loosening a large number of threaded connections in machine manufacturing, locomotive and vehicle repair, shipbuilding, bridge construction, and the automotive industry. Using a pneumatic torque wrench can not only save labor force, significantly improve production efficiency, but also greatly reduce the physical labor intensity of workers. The BQ6 pneumatic torque wrench is suitable for tightening or loosening screws with M8 or M6 sizes.

FAQ
Q: What are the common faults of the 6mm Air Impact Wrench and their handling methods?
A:
|
Fault |
Reason |
Exclusion method |
|
The machine does not rotate or operates abnormally |
The rotor end face is jammed against the front and rear cover planes. 3. The parts are not clean or the lubricating oil viscosity is too high. |
1. Adjust the gap between the rotor and the front and rear covers. 2. Sharpen or replace the new slide plates to ensure they move flexibly within the rotor slots. |
|
Torque drop |
1. The rotational speed is abnormal. |
1. Adjust the engine. |
|
Increased air consumption |
1. The compressed air pipeline and all connection points are leaking air. |
1. Inspect the pipeline and all connection points to eliminate gas leakage. |
Q: What are the precautions for using the 6mm Air Impact Wrench?
A: 1.Atmospheric Pressure and Pipeline Requirements
- The air pressure should be maintained at a gauge pressure of 0.49 to 0.63 megapascals.
- Good oil mist lubricators and air-water separators should be installed on the piping.
- The rubber hose must be intact, and the joints should be secure and airtight.
2.Operation and Storage Specifications
- Machines must not run idle under high pressure for a long time to prevent wear of components and performance degradation.
- When the work is completed, use a plug (or soft material) to block the air inlet passage to prevent dirt from entering the machine interior.
- If machines need to be stored in the warehouse, a small amount of high-viscosity lubricating oil should be injected from the joint, and the machine should be operated for several seconds under low pressure to prevent rust.
3.Lubrication and Maintenance System
- Prime mover: N10 (GB443-89) mechanical oil is selected.
- Bearings, gears and impact mechanisms: ZG-2 (GB491-87) calcium-based grease is selected.
- If the pipeline is not equipped with an oil mist lubricator, an appropriate amount of lubricating oil should be injected at the joint before each use.
4.Maintenance Regulations
- Machines should be regularly maintained, with the maintenance period depending on the degree of use.
- Every time maintenance is performed, the parts must be cleaned thoroughly. Damaged parts should be repaired or replaced with new ones.
