Technical Field

[0001] The utility model relates to the technical field of thin oil lubrication systems, in particular to a flow balancing device for a thin oil lubrication system of port machinery. Background Art

[0002] Thin oil generally refers to lubricating oil with good fluidity and low viscosity. Thin oil lubrication system is a system that supplies lubricating oil to the friction points of machinery and equipment. It has many advantages and is widely used in the lubrication of large-scale machinery and equipment and automated production lines.

[0003] When the existing thin oil lubrication system is working, the oil pump usually sucks the lubricating oil from the oil tank, and the oil is transported to various lubrication points of the equipment to lubricate the relatively moving parts and remove impurities such as metal particles generated during movement. The oil then flows back to the oil tank through the return oil pipe, forming a cycle.

[0004] The existing thin oil lubrication system has the following problems: uneven flow in some pipelines is prone to occur, and the thin oil cannot be distributed to each lubrication point with a reasonable and balanced flow rate, which is very inconvenient to use. For this reason, we propose a flow balancing device for the port machinery thin oil lubrication system. Utility Model Content
