Pipe Threading Machine Is Used In A Harsh Environment

With the development of the domestic economy, the demand for pipeline transmission is increasing. Pipe cutting is one of the indispensable tasks in pipeline laying and pipeline maintenance. Pipe Threading Machine uses many methods for pipe cutting in the pipeline construction stage. Cold pipe cutting, pipe explosion-proof cutting and pipe water cutting are indispensable tools in the pipeline maintenance work.

Pipe Threading Machine is a necessary tool in these pipeline maintenance work. Considering that the Pipe Threading Machine is used in a harsh environment, the bearings used must also have dust-proof, waterproof and rust-proof functions. In the process of use, the cutting and beveling tasks carried by the bearing of the spindle must be heated in the new bearing installation to strengthen the tightness of the spindle and the bearing. The method is as follows:

The correct installation method of the Pipe Threading Machine spindle bearing bearing can extend the service life of the spindle bearing. The installation torque required to install the spindle bearing will increase rapidly as the size of the bearing increases. Therefore, pay attention to size and accuracy when processing the spindle of the Pipe Threading Machine. Due to the requirement of installation force, the bearing of the main shaft is not easy to be pushed onto the shaft or into the bearing seat. Therefore, the bearing or the bearing seat needs to be heated before installation, and the principle of thermal expansion is used for installation. It is strictly forbidden to violently hit the bearing and the spindle to avoid damage during the installation process.

When installing the Pipe Threading Machine, the spindle or bearing must be evenly heated to a certain temperature, not too low or too high. During the installation of the Pipe Threading Machine, pay attention to wearing heat-insulating protective gloves and goggles to avoid personal burns And Shakugan. The temperature is too low to achieve the required seam amount for assembly, so that the heating fails; after the bearing is heated too high, it is equivalent to re-heating the shaft or bearing, which changes the original crystal structure of the original and makes the bearing lose the original Some hardness and wear resistance. When used after assembly, the bearing will peel off the wear-resistant layer and the treated surface. If the over-temperature is serious, the bearing will change color and black. Therefore, mastering the heating temperature is a more important part, which is briefly introduced below:

The general temperature of bearing heating is in the range of 80 to 100 degrees Celsius. When the inner diameter of the bearing is smaller than the main shaft size of the Pipe Threading Machine or the matching interference is large, the heating method is generally used to expand the bearing inner hole and then heat sleeve. Generally, the bearings are heated to 80°C, up to 100°C. Exceeding 120°C will cause backfire in the bearing, which will reduce the hardness and accuracy of the bearing ring and affect the service life of the bearing.
