Description
Technical field
The present invention relates to a kind of hydraulic system maintenance method, be specifically related to a kind of Rapid Cleaning method of hydraulic system closed-loop path.
Background technique
Hydraulic oil is the hydraulic medium that hydraulic system uses, and plays the effects such as energy transferring, system lubrication, anticorrosion, antirust, cooling in hydraulic system, and hydraulic system requires higher at running to the mass property of fluid.According to statistics, the fault of hydraulic system has 70% ~ 85% to cause due to hydraulic oil pollution.When hydraulic system has solid impurity, (metal granule accounts for 75%, dust accounts for 15%, other impurity such as oxide, fiber, resin account for 10%), moisture, other oils and air etc. enter system, or in use hydraulic element wear and tear because long-term relative movement produces, or the pollutant that the new fluid of filling brings, all can cause the pollution of hydraulic oil in system.Hydraulic oil after pollution can accelerate hydraulic system element wearing and tearing, burn even destroy, make the hydraulic performance decline of hydraulic element, the lost of life, finally cause hydraulic system produce fault.As can be seen here, the consequence that hydraulic oil pollution causes is serious.
Hydraulic control oil pollution, reduce the fault of hydraulic system, rotten hydraulic oil will be changed in time, and changing pipeline and the element of cleaning solution pressing system before hydraulic oil, improve system clean degree, within making the turbidity test of fluid remain on the Contamination sensitivity of system core hydraulic element, with the working life of the reliability and element that ensure hydraulic work system, eliminate or reduce to greatest extent the possibility that equipment breaks down in early days.
At present, the cleaning method that hydraulic system is traditional generally has: one, change fuel tank hydraulic oil; Two, hydraulic element are disassembled clean, the cleaning of hydraulic element is comprised again and rocks ablution, test stand ablution and disassembly, cleaning method.Change fuel tank hydraulic oil, method is simple, but cannot eradicate and be attached to impurity on pipeline and hydraulic element and greasy dirt thing, and the rotten hydraulic oil stored in pipeline and hydraulic element cannot be changed, and will cause secondary pollution to newly changing hydraulic oil.Hydraulic element are disassembled cleaning, although the impurity can removed in pipeline and the rotten hydraulic oil be stored in hydraulic element, but require that cleaning personnel possess higher operating technology level, cleaning after installation process easily cause hydraulic system leakage and fault, and unpick and wash, installation and adjustment need take a long time.
Summary of the invention
The object of the invention is to for prior art Problems existing, a kind of Rapid Cleaning method of simple and quick, hydraulic system closed-loop path that cleaning performance is good is provided.
For this reason, the present invention adopts following technological scheme:
A kind of Rapid Cleaning method of hydraulic system closed-loop path, described hydraulic system comprises that valve road is integrated, oil pump, oil inlet pipe, return tube and fuel tank, described oil inlet pipe connects oil pump and fuel tank, described oil pump connection valve road is integrated, integrated and the fuel tank in described return tube connection valve road, described cleaning method comprises the following steps:
(1) by emptying for the hydraulic oil in fuel tank, inject kerosene fuel tank is cleaned, kerosene cleaning after with white silk by inner wall of oil tank wiped clean;
(2) prepare oil drum and the empty oil drum that new hydraulic oil is housed, the oil inlet pipe of hydraulic system and fuel tank are separated and is connected the oil drum that new hydraulic oil is housed afterwards, after being separated with fuel tank by the return tube of hydraulic system, be connected empty oil drum;
(3) open oil pump, under the promotion of new hydraulic oil, the original hydraulic oil in hydraulic system is expelled to sky oil drum, observe the color of the hydraulic oil that return tube flows out simultaneously, the color wait the hydraulic oil flowed out closes oil pump during color specific to new hydraulic oil;
(4) oil inlet pipe and return tube are taken back fuel tank, filling normal fluid pressure oil is to normal oil level, and cleaning terminates.
Further, in step (3), proceed as follows during color specific to new hydraulic oil in the color of the hydraulic oil flowed out by return tube: hydraulic control system carries out crawl operation, namely repeatedly close and open hydraulic system, the interval time of closing and open is 3-5 second, repeatable operation 2-5 time, the color to the hydraulic oil of return tube outflow closes oil pump during color again specific to new hydraulic oil.
Further, in described step (4), before fuel tank filling normal fluid pressure oil, change the hydraulic oil filter cleaner of hydraulic system.
In step of the present invention (3), crawl operation hydraulic system, can make to be adsorbed on impurity on pipeline and hydraulic element and greasy dirt thing because of the repeated stock of hydraulic oil and falling, Impact direction frequently changes, and is constantly washing away lower and pipeline and hydraulic element are separated; Simultaneously, due to the unexpected falling of hydraulic oil, be trapped in after the original rotten or perhaps contaminated hydraulic oil of hydraulic element particularly in valve body can impact losing suddenly hydraulic oil and fall into hydraulic pressure of pipe line flow of oil, multi-pass operation can make the rotten hydraulic oil be trapped in hydraulic element all fall into hydraulic pressure of pipe line oil, is finally all discharged.When observing the hydraulic oil color that return tube is discharged, generally rotten or perhaps contaminated hydraulic oil to be creamy white foam-like usually because of aquation, and mixes and have plurality of impurities; The color that normal hydraulic oil and new hydraulic oil present is generally faint yellow or light blue (depending on hydraulic oil model), limpid, the bright color of oil.
Beneficial effect of the present invention is: simple and quick, without the need to dismantling hydraulic element, utilizing original system to complete cleaning, and taking a short time; Cleaning performance is desirable, the impurity be attached on pipeline and hydraulic element and greasy dirt thing and the rotten hydraulic oil residued in hydraulic element effectively can be removed, ensure newly to change hydraulic oil not contaminated.
