Description

A lithium base grease automatic filling device

technical field

The invention relates to the technical field of vehicle centralized lubrication, in particular to a lithium-based grease automatic grease filling device.

Background technique

With the rapid development of the automobile industry, the energy loss and wear caused by the friction pairs of automobile moving parts cannot be ignored. The lubrication system plays a vital role. In the relevant regulations of our country, the centralized lubrication system of automobile chassis has become a high It is a necessary device for large and medium-sized passenger cars above the grade. The main part of the centralized lubrication system is grease, which is a structural dispersion system formed by base oil, thickener and various additives, and is a typical non-Newtonian fluid. Due to the complexity of the medium flow, the structural design of the centralized lubrication system has been mainly dependent on the experience and skills of engineers and technicians for a long time. Too large, grease deposits and deterioration at the bottom of the fuel tank, insufficient grease injection pressure at the end of the oil separator, etc. The lubricating grease in the centralized lubrication system is generally filled with lubricating grease for the parts of the vehicle to be lubricated regularly through the automatic lubricator. The patent document CN203286249U just discloses a kind of automatic lubricator as publication number, and it comprises cup body, is provided with oil filling port on the outer wall of cup, and oil filling port is closed with dry grease nipple, is provided with oil filling channel on the cup body wall, and the oil filling channel One end communicates with the oil injection port, and the other end of the oil injection channel communicates with the oil inlet located on the bottom of the cup. A connecting rod is fixed on the bottom of the cup body. There are threads on the outer wall of the lower part of the connecting rod for threaded connection with various equipment. The inner opening of the connecting rod There are through holes, and the cup body also has a through hole at the corresponding connecting rod through hole. The through hole on the connecting rod communicates with the through hole on the cup body. There is a hole at the top, a refueling rod is arranged in the cup cover, a sealing disc is fixed on the bottom of the refueling rod, an annular groove is arranged on the outer circle of the sealing disc, and an annular sealing ring is contained in the ring of the sealing disc. This solution pressurizes the lubricating grease in the cup cover through the spring-driven refueling rod and the sealing disc. Obviously, the spring has different elastic forces under different stretching lengths, that is, its pressure on the lubricating grease will change, so that The oil outlet pressure of the grease is constantly changing, which affects the oil output and lubrication efficiency of the lubrication port; and after the grease is consumed, new grease needs to be added from the grease nipple, and the power to drive the sealing disc to move up comes from The filling pressure of the lubricating grease, when the spring is compressed, the elastic force is the largest, which is opposite to the filling pressure direction. When the elastic force is greater than the filling pressure, the lubricating grease can no longer be filled, and it is easy to cause the amount of lubricating grease in the cup cover to be insufficient. , requires frequent refilling, and consumes more manpower and time.
