Description

Grease filling device

Technical Field

The utility model belongs to the technical field of lubricated distributor technique and specifically relates to a drier oil filling device.

Background

In dry oil lubrication systems, the dosing of dry oil is an important step. There are a variety of commonly used dry oil dispensers, including single line progressive dispensers, two line dispensers, etc. The grease with pressure output by the grease pump is quantitatively distributed to each lubricating point through the distributor, and the requirements of the lubricating points are met. The oil feeding amount of each lubricating point is designed and set according to the specific requirements of the running part, so that the lubricating requirements are met, and meanwhile, the waste of grease is avoided.

However, in actual operation, the amount of grease required for each lubrication point on a machine is different. However, as the lubricating points of the same equipment are often supplied with oil by the same dry oil lubricating system, the operating frequency of the distributors in the same area is the same. In conventional dispensers, the amount of oil fed to each outlet of the same dispenser is equal. Thus, the lubricating points in the same area can only be supplied with the same amount of grease. Excessive grease is easy to cause waste, and insufficient grease is easy to cause equipment damage. In addition, the amount of grease needed by a friction pair such as a bearing of a part of a device may change due to abrasion or other reasons after the working condition changes, so that the traditional distributor cannot meet the personalized requirement.
