Description
Technical field
The present invention relates to field of hydraulic lubrication, the detection polluted more specifically to a kind of thin oil oil return pond and its filter core
Method.
Background technology
As shown in Fig. 1,2,3 and 4, on the production line of smelter, the thin oil in the dilute oil lubrication station fuel tank 1 of big flow
Quantitative output is implemented to lubricate to the equipment of the large-scale running such as filmatic bearing, reductor, flying shear.The equipment lubricated has plenty of closed
, have plenty of unlimited.After lubrication, thin oil of the high temperature with impurity returns to fuel tank 1 through oil return pipe 4.The thin oil of fuel tank 1 is returned,
Initially enter in the oil return pond being made up of the supporting plate 1-1 of oil tank wall and horizontal positioned.Have logical on the supporting plate 1-1 in oil return pond
Hole, can place multiple net formula filter cores 3.By the thin oil of Action of Gravity Field in oil return pond, the bottom of fuel tank 1 is fallen into after being filtered through filter core 3,
Enter equipment then again by being pumped out fuel tank 1, then after filtering through pump after-filter to implement to lubricate.Current big flow fuel tank, be
The labour that cost and maintenance are changed is reduced, using open type oil return pond, filter core 3 is that gravity is vacantly placed, and can flexibly be carried
Go out to change.Oil return enters behind oil return pond, is filtered completely by Action of Gravity Field into filter core 3.Generally, maintainer is according to warp
Test, filter core 3 opens the cover plate in oil return pond using reaching after the cycle, and whole filter cores 3 are together changed.Such a maintenance mode is more former
Begin inaccurate, once containing excessive impurity in oil return, into after oil return pond, filter core 3 is easily by short-term internal congestion, if not in time more
Renew filter core 3, the thin oil speed for flowing through filter core 3 can not be completely secured in Action of Gravity Field, cause height of the thin oil in oil return pond rapid
Go up, it is final to overflow oil return pond, cause fluid to waste and environmental pollution.
The height of general big flow Lubricating-oil Station fuel tank top surface from the ground is 3 meters or so, is influenceed by its height, repair and maintenance point
The cover plate that inspection personnel are not easy to open top of oil-tank oil return pond within the short cycle checks filter core situation.If oil spilling occurs relatively to dash forward
So, tend not to predict in advance, cause maintained equipment very passive.At present, opened without a kind of quickly and easily detection big flow
The apparatus and method of open type oil return pond filter core dustiness, can timely and effectively detect the dustiness of hanging filter core, be easy to and
Shi Weixiu changes filter core, improves the cleannes of lubricating oil, it is ensured that lubricating system is normally run.
The content of the invention
It is an object of the invention to overcome thin oil caused by pollution condition due to that can not predict oil return pond inner filter core at present
Overflow problem is there is provided a kind of thin oil oil return pond, and the oil return pond being capable of prompting maintenance personnel replacing filter core；Simultaneously based on the thin oil
