Large round machine wash needle oil

When the engine is running, dry friction will occur if some friction parts are not properly lubricated. Practice has proved that the heat generated by dry friction in a short period of time is enough to melt the metal, causing damage or even jamming of the parts (many leaking or oil-leaking cars have cylinder pulling, shaft holding and other failures, the main reason is this). Therefore, the friction parts in the engine must be well lubricated. When the lubricating oil flows to the friction part, it will adhere to the friction surface to form a layer of oil film, reducing the resistance between the friction parts, and the strength and toughness of the oil film is the key to its lubrication role.

Only a small part of the heat generated after the fuel is burned in the engine is used for power output, frictional resistance consumption and drive of auxiliary mechanisms; Most of the rest of the heat is carried away by the cooling medium in the engine, in addition to being emitted into the atmosphere with the exhaust gases. The excess heat in the engine must be expelled from the body, otherwise the engine will burn out due to excessive temperature. On the one hand, this is done by the engine cooling system, and on the other hand, the lubricating oil absorbs heat from the surface of the cylinder, piston, crankshaft and so on and brings it to the oil pan.

In addition, we have other accessories such as Circular machine oiler, Control Panel, Adjustable Yarn Bobbin Cover, Synchronous Belt, Needle Cylinder and so on.
