An oil pump lubricates machine parts to reduce friction and extend their lifespan. It is commonly found in car engines and needs regular maintenance, including oil changes and level checks. Oil viscosity is important and marked on bottles with a number.
An oil pump is used to supply oil to the moving parts of a machine. The oil helps lubricate the parts so they rotate smoothly with little resistance or friction between them. Not only does it make the machine run smoother, but it extends the life of the machine parts. It also ensures that the parts do not melt or deform due to the heat generated during movement. The most commonly known example of an oil pump is found in the internal combustion engine of a car.
Near the bottom of the engine is the oil pan which stores oil for the oil pump to draw from. The oil pump is mounted inside the oil pan and connected to the engine to ensure they rotate together. Since the oil is pumped under pressure, a sensor is used to monitor the pressure the oil is at. If too much or too little pressure is created, the sensor will cause a warning light to appear in the car. This warns the driver that something is wrong.
The oil pump needs to be taken care of in order for the car engine to continue to run properly. This includes changing the oil roughly every 3,000 to 5,000 miles (4,800 to 8,000 km) depending on how often the car is used and manufacturer recommendations. It’s also important to check your vehicle’s oil level monthly to make sure it has enough oil.
To do this, the owner removes the dipstick located in the engine and wipes it with a paper towel. He then proceeds to dip it back into the holder and pull it out again. A series of lines on the dipstick mark where the oil level should be. If the oil level is below these lines, more oil needs to be added to the car. Oil can be purchased from the store to manually add to the car.
Bottles of oil are marked with a number, such as 10W-30. This number expresses the viscosity of the oil, or how thick it gets at certain temperatures. The oil needs to maintain a certain thickness that is not too thick and not dilute to work. The number next to the W expresses the viscosity of the oil during cold winter weather. A lower number means it will flow better in cold temperatures. The second number expresses how well the oil will flow when hot.
