Maintenance and maintenance of pneumatic wrenches

Pneumatic wrench is the most common type of pneumatic tool used in pneumatic tools. It uses the principle of air pressure to turn screws, etc. It is mainly used in large-scale machinery and equipment. Those who often use tools and equipment should know that the daily maintenance of tools and equipment is better than maintenance. You must not just use them without maintenance, which will reduce the service life of hardware tools. So how does the Dupai pneumatic wrench operate correctly?

In order to keep the best working performance of the pneumatic wrench, a small amount of lubricating oil must be used frequently. It is best to add one to two drops of special oil for pneumatic tools before each use of the tool, which is very critical to the service life of the pneumatic tool. If the air tool oil is not often added before the use of the air tool, it will often cause damage to the shaft and blades of the air tool. In particular, the blades are easily damaged without the addition of special oil for air tools. When the lubricating oil is dripped, it is generally dripped at the pneumatic air inlet, and one or two drops are sufficient.

1. Selection of air pressure before using the pneumatic wrench:

1. The amount of air pressure should be determined according to the material of the object and the torque of the pneumatic tool itself. To set the ideal air pressure, start from a low pressure and gradually increase the pressure until a satisfactory effect is achieved. Before using the tool, check the air pressure and never exceed the specified air pressure, otherwise the tool may burst. Air pressure is required, otherwise the power will not be able to burst.

2. The origin must use dry and dust-free ordinary compressed air, and it is strictly forbidden to use oxygen and any flammable gas to avoid accidental injury.

3. When the nail gun and the trachea are connected, unless the nailing work is performed, do not hold the trigger, so as to avoid accidental firing.

4. After each work, be sure to separate the trachea from the tool.

5. When multiple nail guns use a compressor, the capacity of the compressor must match it, otherwise it will cause insufficient air pressure.

Although pneumatic wrenches are widely used in some large-scale production machinery and equipment, many safety accidents have occurred recently. All operators are advised to pay attention to the operation matters when using the pneumatic wrench, and operate in strict accordance with the operation steps to achieve safe production and safe operation.

As one of the more commonly used tools in hardware tools, wrenches have also changed themselves with the advancement of technology. The pneumatic wrench is one of the new generation of hardware tools, and it is also the transformation of the original ecological wrench. Due to the simple structure of the wrench, the failure rate is low, and the user does not pay much attention to the use and maintenance. In fact, this is very dangerous, especially in small enterprises with incomplete safety measures. Below we will introduce the working principle and maintenance measures of the wrench to you, so that you can better understand the wrench.

2. Use and maintenance:

The compressed air used by the wrench must be cleaned by the oil-water separator and stabilized by the pressure regulator (490~588Kpa). Before use, the compressed air should be connected to the air source, and the joints and the wrench should be checked. Is there any air leak. Use quick connectors. The impact frequency of the wrench is high, and it is necessary to master the time. Maintenance and cleaning (1 to 3 months to disassemble and wash, overhaul and lubricate once.)

Nowadays, pneumatic wrenches are widely used, especially in car assembly and maintenance work. Wrenches are indispensable tools for assembly, disassembly, etc. Wrenches can help workers to complete heavy work. In order to better use the tools to reduce tool damage and prolong the service life of the tools, it is essential to remind the correct operation and daily maintenance of the pneumatic tools. Therefore, it is very important to understand the above information about wrenches.
