Description

Lubricating oil system

Technical Field

The invention relates to the technical field of equipment lubrication, in particular to a lubricating oil system.

Background

Lubricating oil is widely used as a liquid for reducing abrasion by mechanical transmission equipment, but even if well-lubricated equipment is abraded, abrasive grains are produced by abrasion, and if the abrasive grains cannot be effectively removed or prevented from entering transmission parts, the abrasive grains are abraded, so that the abrasion of the equipment is accelerated. Most of mechanical impurities can be filtered out by a filter of the lubricating system, but the filter element is generally selected according to the normal wear working condition of the equipment, so that the running-in wear stage of the equipment at the initial running stage and the abnormal wear stage of the equipment under the degradation condition can not be effectively considered.

In the running-in abrasion stage and the abnormal abrasion stage of mechanical equipment, the content of mechanical impurities in lubricating oil is high, a filter is easily blocked, the pressure difference of an inlet and an outlet of the filter is large, an oil pump generates heat seriously, an oil pump motor is burnt, the normal operation of the equipment is influenced, and the cost is increased due to frequent replacement of a filter element. In addition, even in the normal wear stage of the equipment, the ultra-fine abrasive particles penetrate through the filter screen and enter the kinematic pair to form abrasive particle wear, so that the wear of the parts of the equipment is accelerated. Therefore, how to provide an effective measure to enhance the removal effect of impurities under the premise of normal type selection of the filter becomes a technical problem to be solved by those skilled in the art.

The iron scrap adsorption device 4 comprises a vertical cylinder 41 and a magnetic body 42 positioned in the cylinder 41, the magnetic body 42 is detachably connected with the cylinder 41, an oil drain valve 44 is arranged at the bottom of the cylinder 41, and an oil inlet 411 and an oil outlet 412 are arranged on the side wall of the cylinder 41.

As will be understood from fig. 1 and 2, the on-off valve 5 is disposed at the oil inlet 411, the oil outlet 412 is connected to the inlet of the filter 3, the outlet of the filter 3 is connected to the inlet of the oil pump 2, that is, the lubricating oil flows in the circuit line counterclockwise as viewed in fig. 1, and the iron adsorption device 4 is located upstream of the filter 3.

During the operation of the lubricating oil system, metal particles such as iron, cobalt, nickel and the like contained in the lubricating oil flowing through the cylinder 41 can be adsorbed by the magnetic body 42, and the magnetic body 42 is detachably connected with the cylinder 41, so that the aim of reducing the content of metal abrasive particles in the lubricating oil can be fulfilled by periodically detaching the magnetic body 42 and removing impurities such as iron filings adsorbed on the magnetic body 42, and the abrasion speed of equipment parts can be reduced under the condition of prolonging the replacement period of the lubricating oil.

It will be understood that when the magnetic body 42 is removed, the on-off valve 5 should be closed and the oil drain valve 44 should be opened to drain the lubricating oil in the cylinder 41.

In the embodiment, the magnetic body 42 is designed to be a flat plate shape and is erected at the axial position of the cylinder 41, as shown in fig. 1 and fig. 2, the oil inlet 411 and the oil outlet 412 are located at two sides of the magnetic body 42 and respectively face two plate surfaces of the magnetic body 42, and such a structure is arranged to facilitate the lubricating oil to be in a turbulent state in the cylinder 41, so that impurities such as iron filings in the lubricating oil are captured by the magnetic body 42 more easily, and the purpose of improving the cleaning effect is achieved. Specifically, a connecting line of the oil inlet 411 and the oil outlet 412 may be designed to be perpendicular to the plate surface of the magnetic body 42, as shown in fig. 2.

The height of the magnetic body 42 can be set as required, and in this embodiment, the top end of the magnetic body 42 is located at the center of the cylinder 41, so that the impurities such as iron filings in the lubricating oil can be captured in a large area as much as possible without generating excessive resistance to the flow of the lubricating oil.
