Description

Technical Field

[0001] The utility model belongs to the technical field of lubrication equipment, and particularly relates to a dry oil lubrication system. Background Art

[0002] The centralized lubrication system is the most widely used system in mechanical equipment, which refers to a system that supplies the required lubricating oil and grease to multiple lubrication points. The centralized dry oil lubrication system is widely used in the lubrication of construction machinery, including an electric lubrication pump, a main oil distributor, a sub-oil distributor. The electric lubrication pump is provided with an oil storage tank, and the lubricating oil in the oil storage tank is transmitted to the joints of the moving friction parts of each component through the electric lubrication pump and the oil distributor to prevent wear between these parts due to insufficient lubricating oil.

[0003] The dry oil lubrication pump outputs lubricating grease under a certain pressure of the oil pump. The DRB-P (BS-B) type electric lubrication pump is suitable for single-line and double-line dry and dilute centralized lubrication systems with high lubrication frequency, long pipelines, and dense lubrication points. This series of lubrication pumps are electric high-pressure piston pumps. However, some lubrication pumps are relatively large in size. In order to reduce or avoid the indoor space occupied by the lubrication pump, the lubrication pump needs to be installed outdoors and effective protection for the lubrication pump is required, such as rain protection, moisture protection, and dust protection.
