What is an Oil Pump?
2 Answers
Gasoline pumps serve the function of fuel supply, while diesel pumps not only supply fuel but also control injection quantity, rotational speed, and injection timing. Oil pumps also function to supply oil. Below is an introduction to oil pumps: 1. Overview: An oil pump is a component with precise machining and complex manufacturing processes. Generally, oil pumps for automotive diesel engines, both domestically and internationally, are produced by a few specialized factories worldwide. 2. Properties: Oil pumps can also be suitable for liquids containing hard particles or fibers and are applicable to various viscosities. They can withstand temperatures up to 300°C. For transporting high-temperature liquids, high-temperature resistant gear pumps are recommended, capable of handling liquids up to 300°C. 3. Structure: Various types of oil pumps feature simple and compact structures, are easy to use and maintain, and possess excellent self-priming capabilities, eliminating the need to fill the pump with liquid before each use.
The oil pump is a crucial little component in a car's engine, simply put, it's specifically responsible for pumping engine oil, which acts like blood to lubricate and cool the engine. I remember once when I was driving on a long trip, the car suddenly made a strange humming noise, and the oil warning light on the dashboard lit up, scaring me into pulling over immediately. Later inspection revealed that the oil pump had failed: a small gear inside had worn out, causing insufficient oil pressure, which meant the oil couldn't reach critical areas like the crankshaft, nearly leading to engine seizure. The mechanic explained that oil pumps are mostly gear or rotor-type, driven by the engine's crankshaft, and must maintain working pressure within the normal range; otherwise, like in my case, there's a risk of noise and overheating. Since then, I've developed a habit: regularly changing the oil to keep it clean and checking the oil pressure gauge before starting the engine to prevent such issues. In the long run, proper oil pump maintenance can extend the engine's lifespan.
