Description

Anordning ved pumpeaggregat. Device at the pump unit.

Foreliggende oppfinnelse går ut på en anordning ved pumpeaggregat, omfattende en pumpe og en drivmotor, som er nedsenket under væskenivået i en væsketank. Oppfinnelsen har til formål å tilveiebringe en bedre lyddemping ved et slikt aggregat. The present invention concerns a device for a pump unit, comprising a pump and a drive motor, which is submerged below the liquid level in a liquid tank. The purpose of the invention is to provide better sound attenuation with such an aggregate.

Det er kjent i hydrauliske anlegg å anbringe anleggets matepumpe, samt dets drivmotor nedsenket i en tank for hydraulisk væske. Herved kan oppnås flere fordeler, blant annet at motor- It is known in hydraulic systems to place the system's feed pump and its drive motor submerged in a tank for hydraulic fluid. In this way, several advantages can be achieved, including that engine

og pumpekonstruksjonen kan forenkles betydelig. Imidlertid opp-står det besværlige buldreproblemer. Visse av disse kan over-vinnes ved opphengning av pumpen og motoren i på passende måte an-brakte vibrasjonsdempere. Til tross for dette kan vibrasjoner fra pumpen gjennom væsken forplantes til tankens vegger og gi årsak til forstyrrende bulder. and the pump construction can be significantly simplified. However, troublesome boulder problems arise. Some of these can be overcome by suspending the pump and motor in suitably installed vibration dampers. Despite this, vibrations from the pump through the liquid can be propagated to the walls of the tank and cause disturbing noises.

Ved anordningen ifølge oppfinnelsen er enheten pumpe In the device according to the invention, the unit is a pump

og drivmotor anordnet i tanken under det normale væskenivå ved at den er opphengt i vibrasjonsdempere anordnet i tankens øvre del ovenfor væskenivået, og anordningen ifølge oppfinnelsen karak-teriseres ved at den av pumpen og motoren dannede enheten for en stor del er omgitt av en i tanken i væsken og i avstand fra tankens vegger anordnet avskjerming bestående av i det minste del- and drive motor arranged in the tank below the normal liquid level in that it is suspended in vibration dampers arranged in the upper part of the tank above the liquid level, and the device according to the invention is characterized in that the unit formed by the pump and the motor is largely surrounded by a in the tank in the liquid and at a distance from the walls of the tank arranged shielding consisting of at least part-

vis av lyddempende materiale og anordnet slik at væsken kan passere til pumpen. of sound-absorbing material and arranged so that the liquid can pass to the pump.

Vedlagte tegning viser en utførelsesform for oppfinnelsen. The attached drawing shows an embodiment of the invention.

På tegningen er vist en oljetank 1 med et lokk 2. The drawing shows an oil tank 1 with a lid 2.

En pumpe 3 og en med denne sammenbygget motor 4 er anordnet slik A pump 3 and a motor 4 combined with this are arranged as follows

at de befinner seg under væskenivået 5.. I det viste eksempel er pumpen og motoren opphengt ved hjelp av liner 6 i vibrasjonsdempere 7 av gummi. En ventil 8 er anbrakt på lokket 2, og står i forbindelse med pumpens 1 utløp gjennom en ledning 9. En retur-ledning 10 fører fra ventilen til det indre av tanken. Videre går det ut fra ventilen ikke viste ledninger for forbindelse med de øvrige deler av det hydrauliske anlegg. that they are below the liquid level 5. In the example shown, the pump and motor are suspended by means of liner 6 in rubber vibration dampers 7. A valve 8 is placed on the lid 2, and is connected to the outlet of the pump 1 through a line 9. A return line 10 leads from the valve to the interior of the tank. Furthermore, not shown lines run from the valve for connection with the other parts of the hydraulic system.

Ifølge oppfinnelsen er det omkring pumpen 3 og motoren 4 anbrakt en avskjerming 11, i det viste eksempel utformet som en boks eller kasse med åpningen vendende nedover. Boksen kan være utført av metallplate belagt med skumgummi eller annet lyddempende materiale. Den er anbrakt ved hjelp av ikke viste organer, slik at dens underkant står noe ovenfor bunnen, som vist, slik at oljen utenfor boksen får fri adgang til det indre av boksen. Den er dessuten forsynt med åpninger for ledningene og linene. According to the invention, around the pump 3 and the motor 4 is placed a shield 11, in the example shown designed as a box or box with the opening facing downwards. The box can be made of sheet metal coated with foam rubber or other sound-absorbing material. It is placed by means of means not shown, so that its lower edge is slightly above the bottom, as shown, so that the oil outside the box has free access to the interior of the box. It is also provided with openings for the wires and lines.

Avskjermingens ytre form er relativt betydningsløs, The outer form of the shielding is relatively unimportant,

så lenge den bare i det vesentlige omslutter den av pumpen og motoren dannede enhet, helst såvel oppover som til alle fire sider. as long as it only substantially encloses the unit formed by the pump and the motor, preferably upwards as well as to all four sides.

For ytterligere å forbedre lyddempingen kan man anbringe en lignende boks som omslutter motoren og pumpen underfra. Denne boks utføres med noe større eller noe mindre dimensjoner enn den viste boks, og vender til motsatt side slik at den delvis omslutter eller omsluttes av den viste boks med et tilstrekkelig mellomrom mellom dem til å tillate fri væskesirkulasjon. To further improve sound attenuation, a similar box can be placed which encloses the motor and pump from below. This box is made with slightly larger or slightly smaller dimensions than the box shown, and faces the opposite side so that it partially encloses or is enclosed by the box shown with a sufficient space between them to allow free fluid circulation.
