Detailed introduction of oil pump.

An oil pump is a device that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. It is an essential part of the engine lubrication system, which provides lubrication, cooling and cleaning to the engine parts. There are different types of oil pumps used in internal combustion engines, such as gear type, rotor type and crescent type oil pumps.

The main functions of the oil pump are to transfer oil from the sump to the engine parts that require lubrication, to maintain a constant and adequate oil pressure and flow throughout the engine, to regulate the excess oil pressure by using a pressure relief valve, and to assist in cooling the engine by removing heat from the friction surfaces. The oil pump is driven by the crankshaft or camshaft, which rotates at a certain speed depending on the engine speed. The oil pump draws oil from the sump through a strainer, delivers it to a heat exchanger, and then distributes it to various branches that lead to different parts of the engine. The oil returns to the sump through drain holes or passages, where it is collected and recycled by the oil pump.

Some of the common problems that can affect the performance or function of oil pumps are oil pump failure, oil leakage and oil contamination. These problems can cause low or no oil pressure, noise, leaks or engine damage. To prevent these problems, it is important to replace the old oil pump with a new one when necessary, to check for any signs of wear or damage, to use clean and quality oil, and to follow the manufacturer’s recommendations for maintenance and service. By doing so, you can ensure that your oil pump works properly and efficiently, and that your engine runs smoothly and safely.
