What is the Function of an Automotive Oil Pump?
1 Answers
The functions of an automotive oil pump are as follows: 1. Pressurize and pump the oil from the oil pan to the oil filter and various lubrication channels to lubricate the main moving components of the engine and filter the oil. While the engine is running, the oil pump continuously operates, ensuring the oil circulates within the lubrication system. 2. Since the speed of the oil pump is proportional to the engine speed, its oil supply capacity is weakest at low speeds. Automotive engines typically use two types of oil pumps: gear-type and rotor-type. Both operate on the same principle, transforming low-pressure oil into high-pressure oil through changes in volume, hence they are also known as positive displacement oil pumps. They are characterized by simple structure, reliable operation, and ease of manufacturing and repair. 3. The automotive oil pump is used to extract oil. A pump is a mechanical device that transports or pressurizes liquids. It transfers the mechanical energy from the prime mover or other external sources to the liquid, increasing its energy. Pumps are primarily used to transport liquids such as water, oil, acid-base solutions, emulsions, suspensions, and liquid metals, as well as liquid-gas mixtures and liquids containing suspended solids.
