Description
Technical field
The invention belongs to equipment lubrication and area of maintenance, more particularly to a kind of ceramic brick press that recovers is with viscosity and viscosity
The method of index.
Technical background
Ceramic brick press is the nucleus equipment of ceramic wall and floor bricks industry, and price is high, movement needs are accurate, to the matter of hydraulic oil
Amount requires very high.Viscosity is the leading indicator of ceramic brick press hydraulic oil, is to determine its secondary internal friction, abrasion and lubricating status
Key.Found in production, its viscosity can decline ceramic brick press in use for some time, cause pump, hydraulic valve, oil cylinder etc.
The loss of fluid seepage occurs for position, and friction pair is (such as：Master cylinder system motion contact surface) oil film it is thinning in addition oil film can not be formed and
It is subjected to dry friction and causes piston, oil cylinder, seal etc. to wear and tear.Because the abrasion that dry friction is caused can make seal damage and lose
Effect, causes oil leak, it is also possible to cause hydraulic oil jet, erosion piston rod and seal etc..Therefore, maintain hydraulic oil viscosity steady
Fixed, for reducing the failure of ceramic brick press, to extend its service life very necessary.
The content of the invention
It is an object of the invention to provide a kind of recovery ceramic brick press in the method with hydraulic oil viscosity and viscosity index (VI), with
Reduce equipment fault, reduction maintenance cost and its service life of extension.
The present invention is achieved through the following technical solutions above-mentioned purpose.
A kind of recovery ceramic brick press comprises the steps in the method with hydraulic oil viscosity and viscosity index (VI)：
(1) condition of addition viscosity index improver is determined：When ceramic brick press is run from the place's of draining the oil collection oil sample simultaneously
Survey its viscosity and viscosity index (VI), survey oil sample viscosity compared with fresh oil reduction by 5% or viscosity index (VI) compared with fresh oil reduction by 10%, then need to
Viscosity index improver is added in hydraulic oil in use；
(2) volume of addition viscosity index improver is determined：Viscosity index improver is added in hydraulic oil into use
Volume be V=X × V0, V0 be ceramic brick press fuel load, X be viscosity index improver volumetric concentration, in the range of
1.0~2.0%；
(3) ceramic brick press is stopped, drain line is then connected at ceramic brick press fuel outlet valve, export volume is about
9%V0 hydraulic oil, then adds the viscosity index improver that volume is V, is well mixed；
(4) mixed oil liquid described in step (3) is injected back into ceramic brick press with oiling trolley, and ensures to enter ceramics pressure brick
The oil cleanliness of machine is not less than NAS8 grades, is then turned on ceramic brick press, makes its running no load 20min, then make ceramic pressure
Brick machine carries out normal work.
Further, used viscosity index improver is low molecule amount polyisobutene.
Further, the volumetric concentration of the low molecule amount polyisobutene is 1.6%.
Further, the molecular weight of the low molecule amount polyisobutene is 1200~1375.
Molecular weight is 1200~1375 polyisobutene, and in low temperature, its long-chain molecule is shrunk to bulk substantially, to fluid
Viscosity influence it is smaller.As oil temperature is raised, chain molecule is gradually unfolded, and is made the viscosity of fluid and is increased, and is played increase fluid and is glued
Spend the effect of index.The polyisobutene that molecular weight is 1200~375 is colourless viscous liquid, nonpoisonous and tasteless, and chemical property is stable,
It will not be chemically reacted with the material of other in lubricating oil, with good lubricity, its viscosity is relatively low, under the conditions of 100 DEG C,
Its viscosity is 596~665mm2/ s, and have good miscible type with mineral base oil, so being easy to execute-in-place.In addition, molecule
Measure also has good hydrophobicity for 1200~1375 polyisobutene, be beneficial to after addition the oil of ceramic brick press hydraulic oil-
The improvement of water stalling characteristic and resistance to emulsion.
Embodiment
The technical characterstic of this method is further illustrated with reference to embodiment.
By taking a PH2890 type ceramic brick press as an example, the fuel load of the type ceramic brick press is 1100L, uses certain brand
46# antiwear hydraulic oils, it is 43.21mm to measure viscosity when this hydraulic oil is not used2/ s, viscosity index (VI) is 110.Adopted every 60 days
Collect oil sample and carry out viscosity and viscosity index (VI) measurement, the results are shown in Table 1.
Table 1
As it can be seen from table 1 after hydraulic oil is used 220 days, its viscosity have dropped 6.3% relative to new oil viscosity, it glues
Index decreased 8.1% is spent, the oily leakage phenomenon of oil cylinder is found while checking, press power has declined, therefore makes ceramic pressure immediately
Brick machine is stopped, and drain line, export volume about 9% × 1100L=99L liquid are then connected at ceramic brick press fuel outlet valve
Force feed, then adds the viscosity index improver that volume is 1100L × 1.6%=17.6L, passes through after being stirred with agitator
Mixed oil liquid is filled back ceramic brick press by oiling trolley, and the oil cleanliness ensured into ceramic brick press is not less than NAS8
Level, starts ceramic brick press, makes to be normally carried out suppressing work after its sky load operation 20min, then gathers crude oil sample analysis viscosity
And viscosity index (VI), respectively 42mm2/ s and 121, has arrived at normal operating level.Used viscosity index improver is low
Molec weight polyisobutylene, and molecular weight is 1200~1375.Add after viscosity index improver, being drawn oil sample every 60 days, it is viscous to survey it
Degree and viscosity index (VI), it the results are shown in Table 1, and observe the oil leakage phenomenon disappearance of discovery oil cylinder.
