Description

A kind of use magnetization, the centrifugal and device of adsorption treatment hydraulic oil

[technical field]

The present invention relates to the fuel tank in a kind of hydraulic system, be specifically related to a kind of use magnetization, the centrifugal and device of adsorption treatment hydraulic oil, belong 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.Therefore 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 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 mechanical performance of the Air On Hydraulic System of this dissolved state, the volume modulus of fluid and viscosity also will not produce and significantly affect, the most negligible；Another part is free in fluid with the bubble form of 0.05mm～0.5mm diameter, forms cavitation, is noise, body corrosion and the main cause of volumetric efficiency reduction.Producing heat when bubble is drastically compressed can cause oil temperature to raise, and accelerates fluid oxidation and sealing member is aging, make oil lubrication hydraulic performance decline.The bubble that adulterates in fluid also can reduce the rigidity of fluid, causes automatically controlling malfunctioning, operating mechanism's intermittent movement, positions the adverse consequencess such as inaccurate or 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 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 mostlys come from the abrasion of element.Therefore, the solid grain contamination in degreasing fluid of adopting an effective measure, is another importance of Pollution Control in Hydraulic 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 from hydraulic circuit backflow.Flowing in the hydraulic system oil return of fuel tank and contain various metal and colloidal particles pollutant, the most also include the air existed with bubble shape, the existence of these pollutant can cause hydraulic system hydraulic performance decline even to break down.

5), U-tube 20 is exported by it and oil return enters Rose Box 17；

6), the oil return of Rose Box 17 spill-over is spread along the surface of froth breaking plate 23, and mixes with the fluid in oil box 1, makes the bubble of fluid naturally be dispersed in air；And the magnetic metal net 24 of 23 adsorbs the particle object of remaining in fluid on froth breaking plate；

7) air when, utilizing the dividing plate 8 in oil box 1 and permanent magnet 9 to remove oil-feed and granule；

8), by fuel sucking pipe 2 by the fluid sucking-off of oil box 1, reuse for hydraulic system, and utilize the demagnetizer 5 on fuel sucking pipe 2 to eliminate magnetic particle magnetic, prevent residual magnetism microgranule from entering hydraulic circuit, sensitive Hydraulic Elements are caused damage.

Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, all any modification, equivalent substitution and improvement etc. done within this spirit created and principle, within should be included in the protection domain of this creation.
