Description
[technical field]
The present invention relates to a kind of hydraulic pressure oil treatment process, be specifically related to one and use magnetization, eddy flow centrifugal and adsorption treatment liquid
The method of force feed, belongs to hydraulic oil container technical field.
[background technology]
Statistics both domestic and external illustrate, the fault of hydraulic system about 70% ~ 85% causes due to oil contamination.Cause
This Pollution Control in Hydraulic System has become domestic and international Hydraulic Industry and each industrial department question of common concern.And solid pollution,
Gaseous contamination is two kinds of major ways of hydraulic contamination.
Containing the air of about 9% volume under atmospheric pressure and room temperature condition in fluid, portion of air dissolves in fluid
In, the mechanical performance of the Air On Hydraulic System of this dissolved state, the volume modulus of fluid and viscosity also will not produce
Significantly affect, the most negligible；Another part is free in fluid with the bubble form of 0.05mm～0.5mm diameter, shape
Become cavitation, be noise, body corrosion and the main cause of volumetric efficiency reduction.Heat meeting is produced when bubble is drastically compressed
Cause oil temperature to raise, accelerate fluid oxidation and sealing member is aging, make oil lubrication hydraulic performance decline.The bubble that adulterates in fluid also can drop
The rigidity of low fluid, cause automatically controlling malfunctioning, operating mechanism's intermittent movement, position inaccurate or fix drift etc. bad after
Really.
Solid particle is the pollutant the most universal in hydraulic system, damaging effect is maximum.According to statistics, due to solid
The hydraulic system fault that grain pollutant cause accounts for the 70% of gross contamination fault.In particulate pollutant in hydraulic system oil liquid,
Metal filings occupies certain ratio, and according to different situations, typically between 20% ~ 70%, this part metals abrasive dust is main
Come from the abrasion of element.Therefore, the solid grain contamination in degreasing fluid of adopting an effective measure, is hydraulic system pollution control
Another importance of system.
The hydraulic means used in the production equipment of factory, construction machinery is made up of hydraulic circuit and fuel tank.Fuel tank stores
The hydraulic oil provided to hydraulic circuit and the oil return refluxed from hydraulic circuit.Flow in the hydraulic system oil return of fuel tank and contain
Various metals and colloidal particles pollutant, the most also include the air existed with bubble shape, and the existence of these pollutant can be led
Cause hydraulic system hydraulic performance decline even to break down.
Eliminating problem for solving above-mentioned granule, Chinese utility model patent (Authorization Notice No. CN 203816790 U) is public
Having opened a kind of centrifugal oil purifier, it includes oil pipe before the purification that equipment fuel tank and equipment fuel tank are drawn, and before this purification, oil pipe depends on

Little, cause adsorption time long, the problems such as adsorption effect is poor.
3. part magnetic microparticles enters hydraulic circuit, and absorption causes element fault on Hydraulic Elements and is difficult to cleaning
Remove.
And be to solve above-mentioned bubble to eliminate problem, conventional way is to arrange longitudinal baffle in fuel tank, extends fluid and exists
The time of staying in fuel tank, should arrange far into and out of hydraulic fluid port as far as possible, and increase the volume of fuel tank.But, owing to mixing oil return
Bubble the least and oil viscosity is of a relatively high, therefore there is problems in that bubble rises to pasta and is scattered in air need
Long period, 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 discloses a kind of fuel tank, this fuel tank
Extend the oil return fluid time of staying at liquid level by the incorporating section being arranged in fuel tank and rectifying wings, reach eliminate bubble and
Inlet port is avoided to suck the purpose of bubble.Then, the defaoming mechanisms of above-mentioned fuel tank is nature froth breaking, still there is foam time
Long, the problems such as efficiency is low, especially for the operating mode poor effect that changes in flow rate is violent.
Therefore, for solving above-mentioned technical problem, necessary offer one uses magnetization, eddy flow centrifugal and adsorption treatment liquid
The method of force feed, to overcome described defect of the prior art.
