An oil drain 門栓, also known as an oil drain bolt, is a critical component in machinery, engines, and other mechanical systems that use oil for lubrication or cooling. It is typically located at the lowest point of an oil reservoir or sump, allowing for the controlled drainage of used or contaminated oil during maintenance or oil changes.
Key features of an oil drain bolt include:
-
材質: Often made from metals like steel, aluminum, or stainless steel to resist corrosion and provide strength under pressure.
-
Sealing Mechanism: The screw typically has an integrated sealing surface or uses an o-ring or gasket to ensure a leak-proof seal once it’s tightened.
-
設計: It may come with a hexagonal or square head to allow for tightening or loosening with a wrench. Some designs include a built-in valve or a drain hole for controlled oil release.
-
應用: Commonly used in automotive engines, machinery, industrial equipment, or any system requiring oil lubrication or fluid containment.
-
Sizes and Thread Types: Available in various sizes and thread types to match the specific design requirements of the system.
-
目的: To securely close oil compartments or fluid reservoirs while preventing dirt or debris from entering. It may also be designed for easier inspection or fluid changes.
