Description
[technical field]
The present invention relates to a kind of hydraulic pressure oil treatment process, be specifically related to a kind of use electrification,
Helix tube magnetic field separates and the method for adsorption treatment hydraulic oil, belongs to hydraulic oil container technology neck
Territory.
[background technology]
Statistics both domestic and external illustrate, the fault of hydraulic system about 70%～85%
Owing to oil contamination causes.Therefore Pollution Control in Hydraulic System has become domestic and international liquid
Pressure industry and each industrial department question of common concern.And solid pollution, gaseous contamination are
Two kinds of major ways of hydraulic contamination.
Fluid contains under atmospheric pressure and room temperature condition the air of about 9% volume,
Portion of air is dissolved in fluid, the machinery of the Air On Hydraulic System of this dissolved state
Performance, the volume modulus of fluid and viscosity also will not produce and significantly affect, and typically may be used
Ignore；Another part is free in oil with the bubble form of 0.05mm～0.5mm diameter
In liquid, form cavitation, be the main of noise, body corrosion and volumetric efficiency reduction
Reason.Producing heat when bubble is drastically compressed can cause oil temperature to raise, and accelerates fluid oxygen
Change and seal is aging, make oil lubrication hydraulic performance decline.The bubble that adulterates in fluid also can drop
The rigidity of low fluid, causes automatically controlling malfunctioning, operating mechanism's intermittent movement, location not
Accurately or the adverse consequences such as fix drift.
Solid particle is the pollutant the most universal in hydraulic system, damaging effect is maximum.According to
Statistics, the hydraulic system fault caused due to solid grain contamination accounts for gross contamination event
The 70% of barrier.In particulate pollutant in hydraulic system oil liquid, metal filings occupies one
Fixed ratio, according to different situations, typically between 20%～70%, this part gold
Belong to abrasive dust and mostly come from the abrasion of element.Therefore, adopt an effective measure in degreasing fluid
Solid grain contamination, be another importance of Pollution Control in Hydraulic System.
The hydraulic means that the producing of factory uses in equipment, construction machinery by hydraulic circuit and
Fuel tank is constituted.Fuel tank stores the hydraulic oil provided to hydraulic circuit and returns from hydraulic circuit
The oil return of stream.Flow in the hydraulic system oil return of fuel tank and contain various metal and colloid
Grain pollutant, the most also includes the air existed with bubble shape, depositing of these pollutants
Even break down hydraulic system hydraulic performance decline can be caused.
Problem, Chinese invention patent (Authorization Notice No. CN is eliminated for solving above-mentioned particle
203816790 U) disclose a kind of centrifugal oil purifier, it includes equipment fuel tank and equipment
Oil pipe before the purification that fuel tank is drawn, before this purification, oil pipe is sequentially connected with service tank, self-priming
Pump, centrifugal basket, after this centrifugal basket connects purification, oil pipe is connected to equipment fuel tank, also wraps
Include vavuum pump to be connected with service tank；In described service tank, wherein it is provided with strong magnetic magnet.
Therefore, before entering centrifugal barrel at fluid, the metal impurities in fluid are adsorbed, reduce
The metallic particles abrasion to equipment, is effectively increased the service life of equipment.
Then, there is following several respects problem in above-mentioned oil conditioner:
1. need to add a whole set of separator, equipment is complicated, and cost is high, can give fluid simultaneously
Bring secondary pollution.
2. fuel tank volume is relatively big, and the magnetic conductivity of fluid is poor, and strong magnetic magnet is to micro-in fluid
The problems such as the active force of scale particles is less, causes adsorption time long, adsorption effect difference.
3. part magnetic microparticles enters hydraulic circuit, and absorption causes element on Hydraulic Elements
Fault and be difficult to clean remove.
And be to solve above-mentioned bubble to eliminate problem, conventional way be arrange in fuel tank vertical
To dividing plate, extend the fluid time of staying in fuel tank, should arrange into and out of hydraulic fluid port as far as possible
Obtain far, and increases the volume of fuel tank.But, due to mix the bubble of oil return the least and
Oil viscosity is of a relatively high, therefore there is problems in that bubble rises to pasta and is scattered to
Needing the long period in air, hydraulic means cannot be carried out work during this period.
The practical application for a patent for invention (application publication number CN 102762874 A) of China is public
Having opened a kind of fuel tank, this fuel tank is prolonged by incorporating section and the rectifying wings being arranged in fuel tank
Long oil return fluid, in the time of staying of liquid level, reaches eliminate bubble and avoid inlet port to suck
The purpose of bubble.Then, the defaoming mechanisms of above-mentioned fuel tank is nature froth breaking, still exists
The problems such as foam time is long, and efficiency is low, especially for the operating mode effect that changes in flow rate is violent
Fruit is the best.
Therefore, for solving above-mentioned technical problem, the employing electrification of necessary offer one,
Helix tube magnetic field separates and the method for adsorption treatment hydraulic oil, of the prior art to overcome
Described defect.
