Description

Quick oil change system

technical field

The invention relates to a quick oil change system.

Background technique

Lubricating oil, hydraulic oil and hydraulic transmission oil are used in mechanical equipment and transportation tools. The function of the mechanical lubrication system is to continuously deliver sufficient quantity and moderate temperature oil to all transmission parts when the machine is working. The friction surface forms a continuous oil film between all friction surfaces to realize liquid friction, thereby reducing friction resistance, reducing machine wear, and reducing power consumption, so as to achieve the purpose of improving the reliability and durability of the engine. In addition, the oil flows through the working surface of the parts during the circulation process, which can reduce the temperature of the parts and take away the metal debris generated by friction. At the same time, the formed oil film can also play a role in sealing and preventing leakage and corrosion of parts. With the use of mechanical equipment, all kinds of oils work in high temperature, high pressure and high speed environment for a long time, and they are easy to deteriorate. On the one hand, the oil is oxidized by air at high temperature, which leads to changes in its physical and chemical properties, affecting The performance of engine oil; on the other hand, metal debris generated by the relative movement of mechanical parts, as well as dust and impurities from the external environment, are mixed in the oil, which is also a major cause of oil deterioration. After the oil deteriorates, its protective effect on the machine parts will also be greatly weakened. The deteriorated oil will not only fail to lubricate, cool, and clean, but will aggravate the wear and tear of the machine parts and increase consumption. In severe cases, it may even damage the normal operation of the machine. Therefore, the oil needs to be replaced regularly.

Take the oil change of a transportation vehicle as an example. Since the car uses lubricating oil, the oil change method is manual oil change. After lifting the car, open the engine guard plate, and unscrew the oil pan bolt at the bottom of the engine to drain the oil. When draining the old oil, put the old oil into the oil receiving basin, screw back the oil drain screw after draining the old oil, replace the oil filter, and then add new oil from the upper engine oil hole.

With the development of society, there are more and more cars. When car owners go to the after-sales service station to repair and change oil, they often need to wait in line. According to the survey results, insufficient maintenance and oil change stations are one of the important reasons for car owners to wait. In order to reduce the waiting time of customers, the after-sales service station needs to increase the utilization rate of the maintenance and oil change stations in a limited space, so as to solve the problem of insufficient maintenance and oil change stations. The only way to improve the efficiency of the traditional manual oil change is to shorten the Oil change time, but shortening the time will make the old lubricating oil not flow clean before screwing on the oil pan bolts, and when new oil is added, it will mix with the residual old oil, which will cause contamination of the new oil, thus affecting the quality of oil change , affect the performance of the parts, cause wear and tear on the parts, and cause customer dissatisfaction.
