Description

Ferfarande fOr rertvattning av hydraulsystem samt anlaggning hart Or. Procedure for re-irrigation of hydraulic systems and installation hard Or.

Foreliggande uppf inning avser ett forfarande for rartvattning av hydraulsystem invandigt genom genomstromning av sagda hydraulsystem med fluid i stramfling med ett Reynolds tal pA minst 2300. The present invention relates to a process for irrigating hydraulic systems internally by flowing through said hydraulic fluidized fluid system with a Reynolds number of at least 2300.

Rorspolning, d.v.s. tvattning av hydraulsystem invandigt enligt kanda forfaranden i samband med en fluid i turbulent stromning av minst Re 3000 tillgar bl.a. pa sá satt att man mater fluidens kontamineringsgrad med bl.a. partikelraknare enligt ISO 4406:1999 eller NAS 1648 eller med andra kanda liknande forfaranden. Av rorsystem for hydrauliska anlaggningar foreligger problem att sakert och effektivt kunna fA alla delar i fartyget i funktions- dugligt skick pa kort tid och med bra resultat. Rudder flushing, i.e. washing of hydraulic systems internally according to known procedures in connection with a fluid in turbulent flow of at least Re 3000 adds i.a. in such a way that you measure the degree of contamination of the fluid with e.g. particle calculators according to ISO 4406: 1999 or NAS 1648 or other similar procedures. There are problems with rudder systems for hydraulic systems to be able to safely and efficiently get all parts of the vessel in working order in a short time and with good results.

Sedan den moderna hydraulikens intag pa 70-80 talet har det globalt visat sig vara mycket problematiskt att fullborda en korrekt tvattning. Detta visar sig i form av hydrauliska haverier, lackande tatningar, skadade och fixerade ventiler etc., vilket foranleder hoga reparationskostnaderna samt besvikna kunder som medfOr minskat leverantorsfortroende. Since the advent of modern hydraulics in the 70s and 80s, it has proven globally to be very problematic to complete a correct wash. This is manifested in the form of hydraulic breakdowns, varnishing seals, damaged and fixed valves, etc., which leads to high repair costs and disappointed customers, which leads to reduced supplier confidence.

Ombord pa t.ex. fartyg maste man innan leverans av fardigbyggt och installerat fartyg lAta tvatta samtliga hydraulmanovrerade ramper, portar, bildack och luckor och vilka har minst dubbla roravsnitt. Vardera roravsnitt maste darvid kopplas till och fran aktuell rortvattningsstation fOr att genomga avsedd rorspolning. Totalt kan det overstiga flera hundratal enskilda ror- tvattningar for vane fartyg vilket kan ta Over en mamad i ansprak. Detta motiverar saledes en automatisering. On board e.g. ships must be washed before delivery of prefabricated and installed vessels of all hydraulically operated ramps, gates, car decks and hatches and which have at least double rudder sections. Each pipe section must then be connected to and from the current pipe irrigation station in order to undergo the intended pipe flushing. In total, it can exceed several hundred individual rudder washes for used vessels, which can take Over a mamad in claim. This thus justifies an automation.

Grundorsaken an Overvagande den allmant bristande kunskapen mom rortvattningstekniken tillsammans 1 med den sA ofta underskattade betydelsen av ett rent system. Likaledes visas hur svArt och kostsamt det faktiskt ar att atgArda ett kontaminerat system i efterhand am det ens är mojligt utan fullstandiga komponent- byten. The root cause of Overwhelming the general lack of knowledge regarding the irrigation technique together with the often underestimated importance of a clean system. It is also shown how difficult and costly it actually is to repair a contaminated system afterwards, even if it is even possible without complete component replacements.

Det är ocksA viktigt att operatoren som utfor arbetet har tillgAng till en station med kapacitet nog att leverera erforderligt flode. Just detta har visat sig mycket bekymmersamt da valdigt fa brukare klarar av att dimensionera vilken motor och pump etc som krAves for att utfora en rOrtvAttning som uppfyller Atminstone Re 3000. Re 3000 är den internationellt vedertagna flodesstrOmningen fOr andamAlet men aven Re 4000 forekommer. It is also important that the operator performing the work has access to a station with sufficient capacity to deliver the required flow. This has proved to be very worrying as very few users are able to dimension which motor and pump etc is required to carry out a pipe drain that meets at least Re 3000. Re 3000 is the internationally accepted river flow for the spirit but also Re 4000 occurs.

Far att verifiera kapacitet av en befint- hg station kravs aven berakningskunskaper mom hydraulik, vilket utovaren oftast inte besitter eller kan krAvas pa. In order to verify the capacity of an existing station, calculation skills such as hydraulics are also required, which the practitioner usually does not possess or can be required to do.

Det ovan angivna Ar ett internationellt problem som kontinuerligt drabbar de stora OEM-tillverkarna mom exempelvis offshore & marinsektorn. The above is an international problem that continuously affects the major OEM manufacturers, for example the offshore & marine sector.

Huvudandamalet med den foreliggande upp- finningen är darfor i forsta hand att losa bl.a. ovan sagda problem, och Astadkomma kortare tvAttningstider, automatiserad tvattning och automatisk loggning av erhAllna vArden till skillnad frAn dagens manuella forfarande. The main object of the present invention is therefore primarily to solve e.g. problems mentioned above, and Achieve shorter washing times, automated washing and automatic logging of the values obtained, in contrast to the current manual procedure.

Sagda andamAl uppnAs medelst ett forfaran- de enligt foreliggande uppf inning, som i huvudsak kAnnetecknas darav, att man med en styrenhet som reglerar i nyttjad anlAggning ingaende motor, pump samt anskad reningsgrad genom Aterkoppling av motorvarvtal, oljeflode, oljereningsgrad och oljetemperatur, Astadkommer automatisk rening av ror med hjalp av olja eller av annan fluid som nyttjas i ett sa kallat Aterkopplat system med av styrenheten automatiskt utforda korrigeringar far att uppratt- 2 halla minst ett forutbestamt varde pa Reynolds tal efter forutbestamt onskat slutresultat av reningsgraden, innan godkand resultatrapport kan levereras i ett anvandargranssnitt. Said objectives are achieved by means of a procedure according to the present invention, which is mainly characterized by the fact that with a control unit which regulates the used plant, the engine, pump and desired degree of purification by feedback of engine speed, oil flow, oil purification rate and oil temperature, A. of pipes with the help of oil or other fluid used in a so-called Feedback system with corrections automatically challenged by the control unit must maintain at least one predetermined value of Reynolds number after predetermined desired end result of the purification rate, before an approved result report can be delivered in a user interface.

Uppfinningen avser alien en anlaggning for genomf5rande av forfarande enligt nagot av ovan angivna patentkrav for rortvattning av hydraulsystem invandigt genom genomstromning av sagda hydraulsystem med fluid i stromning med ett Reynolds tal pa minst 2300. The invention relates to a plant for carrying out a method according to any one of the above-mentioned claims for irrigating hydraulic systems internally by flowing through said hydraulic system with fluid in flow with a Reynolds number of at least 2300.

En sagda anlaggning kannetecknas bl.a. av, att i anlaggningen ingaende styrenhet innefattar medel som mojliggor att styra i sagda anlaggning ingaende motor, pump samt Onskad reningsgrad, att sagda styrenhet ar anordnad att mottaga varden frail Aterkoppling av motor- varvtal, oljeflode, oljereningsgrad och oljetemperatur, och att sagda styrenhet ãr anordnad att astadkomma automatisk rening av ror med hjalp av olja eller av annat fluid som nyttjas i ett Aterkopplat system varvid styrenheten innefattar medel som mojliggor att utfora automatiska korrigeringar pa anlaggningen efter forutbestamt onskat slutresultat av reningsgraden, innan godkand resultatrapport kan levereras i anvandargranssnitt. A said plant can be drawn i.a. that the control unit included in the system comprises means which make it possible to control the motor, pump and undesired degree of purification in said system, that said control unit is arranged to receive the value from the feedback of engine speed, oil flow, oil purification degree and oil temperature, and that said control unit arranged to provide automatic cleaning of pipes with the help of oil or other fluid used in a Feedback system, wherein the control unit includes means that enable automatic corrections to be made to the plant after predetermined desired end result of the degree of purification, before an approved results report can be delivered in user interface.

Enligt foreliggande uppf inning flyttas nu kunskaperna betraffande den invandiga rortvattningen fran operatorerna till en styrenhet fOr genomforande av sagda forfarande far rartvattningen och till en anlaggning for genomforande av ett sagda forfarande enligt uppfinningen. Sagda styrenhet kan utgoras av mjukvara som nyttjas i en dator och enligt uppfinningen astadkommer man avsedd rening av raren med hjalp av olja eller annan fluid i ett s.k. aterkopplat system till skillnad fran tidigare nyttjade "Oppet system". 3 Enligt uppfinningen flyttas nu kunskaperna frAn utovaren till mjukvaran och erbjuder ett mycket enkelt anvAndargrAnssnitt 14. According to the present invention, the knowledge concerning the internal pipe irrigation is now transferred from the operators to a control unit for carrying out said procedure for the water treatment and to a plant for carrying out said method according to the invention. Said control unit can be constituted by software which is used in a computer and according to the invention the intended cleaning of the tube is achieved with the aid of oil or other fluid in a so-called reconnected system unlike previously used "Open system". According to the invention, the knowledge is now transferred from the user to the software and offers a very simple user interface 14.

Mjukvaran anvAnder ett flertal matematiska formler for att reglera pumparnas utflode sA att minst Re 3000 eller 4000 flodesstromning alltid levereras oavsett fluidens temperatur och rorstorlek samtidigt som inbyggda funktioner sAkerstAller att onskad renhet alltid uppnAtts innan godkAnd resultatrapport kan levereras. SAledes skapas en helautomatisk tvAttningsstation. The software uses a number of mathematical formulas to regulate the outflow of the pumps so that at least Re 3000 or 4000 river flow is always delivered regardless of the fluid temperature and pipe size while built-in functions ensure that the desired purity is always achieved before an approved result report can be delivered. This creates a fully automatic washing station.

ELL traditionellt rortvattningssystem opererar enligt principen oppet system vilket betyder att systemet ej behandlar Aterkopplade parametrar och sAledes inte kan utfora rektifierade AtgArder for att uppnA ett forutbestAmt resultat. ELL traditional pipe irrigation system operates according to the principle of open system, which means that the system does not process Feedback parameters and thus cannot perform rectified Actions to achieve a predetermined result.

Traditionella system behandlar ej Aterkopplade parametrar eller saknar i vissa fall helt Aterkoppling frAn systemet och kan dA sAledes inte sAkerstAlla att ratta forutsAttningar vid tvattning gAller vid ett givet rorsystem. Traditional systems do not deal with Feedback parameters or in some cases have no Feedback from the system at all and can therefore not ensure that the conditions for washing apply to a given rudder system.

Vanligtvis kors en elmotor pA cirka 1500 V/min som i sin tur driver en fast eller tryckkompenserad pump. Usually an electric motor at about 1500 V / min is crossed, which in turn drives a fixed or pressure-compensated pump.

Denna traditionella metod har bl.a. nedan 25 angivna nackdelar: Ingen Aterkoppling till systemet som visar om rortvAttningen Ar OK eller ej. This traditional method has i.a. 25 disadvantages listed below: No Feedback to the system which shows whether the pipe washing is OK or not.
