Description

Technical Field

[0002] During the maintenance of water pumps, we often encounter large nuts that are difficult to remove due to rust and other reasons. In the prior art, workers often heat the large nuts directly with open flames or high-frequency heating. Due to the nature of thermal expansion and contraction, the large nuts can be detached from the screws. However, using open flames for heating will bring safety problems, and operators are prone to burns during the removal of heated large nuts, which is unsafe and labor-intensive. Therefore, we propose a heating device for large nuts for water pumps.
