What is the function of the oil pump body?

The function of the oil pump is to raise the oil to a certain pressure and then forcibly deliver it to the moving surfaces of various engine components, achieving forced lubrication. The oil pump is a device in the automotive lubrication system used to increase oil pressure, helping oil move from the oil pan to other lubricated components. Oil pump classification: Oil pumps can be divided into two types based on their structural forms: gear-type and rotor-type. Gear-type oil pump: It provides high oil pressure, has a simple structure, is easy to manufacture, operates stably, and has a long service life, making it widely used. Gear-type oil pumps are further divided into internal gear-type and external gear-type, with the latter generally referred to as gear-type oil pumps. Rotor-type oil pump: Rotor pumps are often made by powder metallurgy pressing, featuring small size and compact, complex structure, but they also share some advantages of gear pumps. Working principle: When the engine is running, the drive gear on the camshaft drives the transmission gear of the oil pump, causing the driving gear fixed on the driving gear shaft to rotate, which in turn drives the driven gear to rotate in the opposite direction, moving the oil from the inlet chamber through the gear gaps and pump walls to the outlet chamber. As a result, a low pressure is formed at the inlet chamber, creating suction that draws oil from the oil pan into the oil chamber. As the driving and driven gears continuously rotate, oil is constantly pressurized and delivered to the required parts.

I've been working in the automotive repair industry for several years and frequently deal with oil pump failures. The main function of the oil pump is to draw oil from the bottom of the engine, pressurize it, and then distribute it to various critical parts of the engine for lubrication. Components like the crankshaft and camshaft rely heavily on oil for protection and cooling. If the pump fails, oil pressure drops, leading to increased friction between parts, overheating, and even engine seizure. I've seen many car owners neglect regular inspections, resulting in costly engine repairs. Besides the pump itself, keeping the oil pan and oil passages clean is crucial, as the pump's filter screen can easily get clogged with debris. During maintenance, remember to replace the oil, typically checking every 5,000 to 10,000 kilometers to prevent major issues. The engine's lubrication system is a chain where one weak link can cause significant problems—prevention is always better than cure.

As a veteran driver with 20 years of experience, I've personally witnessed how crucial the oil pump is. Its job is to draw oil from the tank, pressurize it, and deliver it to all moving parts of the engine for lubrication, reducing noise and wear. An engine without lubricating oil is like a human without blood—it just doesn't run smoothly. Once, my car's oil warning light came on, and upon inspection, I found the pump's intake was clogged, nearly ruining the engine. After that scare, I learned my lesson: now, during every maintenance check, I have the technician inspect the oil level and change the oil. The pump's proper operation depends on good oil quality and a clean system, especially if you frequently drive long distances. Keeping this pump in good health can extend your car's lifespan and save you money on fuel. Safety comes first when driving—don't let small issues turn into major problems.

As an automotive engineer, I have designed numerous lubrication system components. The oil pump's function is to draw oil from the oil pan, pressurize it, and distribute it to critical areas such as bearings and pistons, ensuring continuous lubrication to reduce friction and overheating. Structurally, it utilizes gear rotation to generate oil pressure, covering the entire engine. During design, it's crucial to optimize flow rate and pressure to prevent oil pressure deficiency caused by high-speed operation. Efficient lubrication directly enhances engine durability and overall performance, requiring meticulous attention to detail.
