In various mechanical equipment, in addition to widely using thin oil lubrication, lubricating grease (abbreviated as dry oil) lubrication is also used in many friction pairs. For example, certain friction pairs of blast furnace top equipment.
In various mechanical equipment, in addition to widely using thin oil lubrication, lubricating grease (abbreviated as dry oil) lubrication is also used in many friction pairs. For example, certain friction pairs of blast furnace top equipment; The meshing part of the gear ring of the tilting mechanism of the steelmaking workshop furnace; Certain lubrication points on various metallurgical cranes; The flat friction pair between the rolling mill bearing seat and the frame window in the steel rolling mill; Straightening machine straightening roller bearings, certain friction pairs of shear units; The bearings of the roller deck group vary depending on the condition of the friction pair. There is no separate and dispersed lubrication method (i.e. manually adding grease to the lubrication points or grease cups using a grease gun); Some have difficulties using manual greasing due to the large number of friction pairs and the limitations of working conditions (such as high temperatures, multiple lubrication points, busy manual greasing, and difficulty in approaching lubrication points). It is necessary to use a dry oil centralized lubrication system to regularly add lubricating grease.
Classification of centralized lubrication of dry oil:
The dry oil centralized lubrication system uses lubricating grease as the lubricating medium for mechanical friction pairs. A complete set of equipment for supplying lubricating grease to lubrication points through a dry oil station. Due to the different research basis of dry oil centralized lubrication systems, the classification methods are also different. Currently, the general classification methods are:
1. According to the number of pipelines supplying grease to the lubrication point
(1) Single line (single line) grease supply dry oil centralized lubrication system
(2) Dry oil centralized lubrication system for dual pipeline (dual line) grease supply
2. According to the driving mode of the grease supply
(1) Manual dry oil centralized lubrication
Manual dry oil centralized lubrication system
1- Manual oil drying station; 2- Dry oil filter; 3-dual wire oil feeder; 4- Oil grease branch pipe; 5- Bearing pair
6-directional valve; I, II - Oil transfer grease main pipe
(2) Automatic dry oil centralized lubrication system. Due to different power sources, it can be divided into two categories: electric and pneumatic.
3. According to the layout type of the dual line grease supply pipeline
(1) Outflow (end flow) type dry oil centralized lubrication system
Outflow type dry oil centralized lubrication system
1- Electric dry oil station; 2- Electromagnetic directional valve; 3- Dry oil filter; 4- Oil grease branch pipe; 5- Bearing pair
6-directional valve; I, II - Oil transfer grease main pipe
(2) Ring type (loop type) dry oil centralized lubrication system
Ring type dry oil centralized lubrication system
1- Oil storage tank; 2- Hydraulic directional valve; 3- Oil feeder; 4- Limit switch; 5- Reducer;
6- Electric motor; 7- Plunger pump; I, II - Fat conveying supervisor
4. According to the action sequence of pressing grease to the lubrication point during single line grease supply (single line oil feeder)
(1) Single line sequential
Single line sequential dry oil centralized lubrication system
1- Fat conveying supervisor; 2- Dry oil filter; 3- Control valve; 4- Dry oil pump;
5- Main oil supply pipe; 6- Fat conveying branch pipe; 7-Secondary oil feeder
(2) Single line non sequential
Single line non sequential dry oil centralized lubrication system
1- Dry oil pump station; 2- Control valve; 3- Fat conveying supervisor; 4- Oil feeder
(3) Single line loop type
