- the fluid in question can also be partially provided with abrasion, for example from movable rubber seals or the like. to arise. Furthermore, it is Fluid regularly mixed with the working gas. If you want clas going Fluid from the container, for example in the form of a piston accumulator, in particular Removing from its gas side is usually the for a long time to shut down the entire hydraulic system or at least part of the system, which has the piston accumulator to be maintained and cleaned the mentioned long downtime of the system are then for the Maintenance of the container to adhere to exact safety regulations, what overall the maintenance process can be complex and costly. Also build the well-known maintenance facilities, if necessary Allow refilling the gas side of the container with a working gas, constructively big on and are difficult to handle.
- a container for gaseous media is known from DE 297 22 504 U, especially large pipeline, with an inlet connection and a Outlet connection, as well as with a ventilation and drainage connection, with the inlet connection and the outlet connection at the same time as ventilation and drainage connections are formed.
- the inlet port comprises two inlet pipes which are connected from a side inlet connection of the Container in the arch led to a high point inside the container are, wherein the outlet nozzle comprises two outlet tubes, one of which Low point inside the tank in an arc to a side outlet connection of the container are guided.
- the water pressure test summarizes.
- the object of the invention based on a small-sized fluid extraction device as a maintenance unit to be made available with very short downtimes connect to the container and disconnect from it in order overall the maintenance effort and the associated maintenance costs decrease significantly.
- a device solves this problem with the features of claim 1.
- the device is operated in such a way that after its connection the prevailing differential pressures between the container and the collecting container the device from the fluid, which may contain gas is brought out of the container and transported into the collecting container.
- the collecting container then preferably allows a settling process Fluid components, in particular in the form of contaminated fluid, wherein the gas components via the equalization line and the equalization connection can flow back the gas side of the container.
- This is a kind closed circuit realizes the permanent operation of the device allowed without it due to unwanted pressure increases or the like. can interfere with the oil extraction process.
- the container only needs one of the Compensating connection various extraction connection at a deep point of the container to be arranged, on which the fluid with the gas collects
- the device according to the invention can be used in particular Quickly connect quick coupling devices to the container and separate from this again so that a removal process takes place very quickly can go and the machine downtimes are short.
- a structurally small-sized collection oil tank achieve a compact design for the overall device.
- Nitrogen occurs as a gas loss for the container.
- the device shown in FIG. 1 serves to remove fluid, in particular hydraulic oil from a container 10 containing a gas, especially in the form of nitrogen gas.
- a removal connection 14 is used to which a Withdrawal line 16 a collection container 18 can be connected, which in turn via a compensating line 20 with one arranged on the container 10 Compensating connection 22 is connectable, which is different from the one addressed Discharge connection 14.
- the container shown in Fig.1 provides a so-called hydraulic accumulator in the form of a piston accumulator with a Separating element (not shown) that is common in this type of storage Way separates the fluid side 24 from the gas side 26 of the container, wherein the piston accumulator and thus the container 10 in such a horizontal manner Installation position is maintained that actually the removal port 14 in the lid 28 of the container 10 opens onto its gas side 26, in the area the deepest, i.e. the lowest point of the storage.
- the removal connection 14 is in particular in the form of a stub line formed, which passes through the cover 28 and towards the gas side 26 in Looking towards the Fig. 1 turns at right angles downwards and flows into gas side 26 there. This ensures that actually in the horizontal installation position at the lowest point of the container 10 the fluid withdrawal process takes place, the fluid taking the form of Hydraulic oil settles down due to gravity and settles at the collection point 12 collects. Between the bend in the stitch-like extraction connection 14 and the surrounding area is an O-ring seal in the cover 28 arranged the cover 28 opposite the inside of the housing of the container 10 seals.
- the oil removal device at a piston accumulator is used, in any case continuously from the fluid side 24 oil via the seals of the separating element (not shown) on the gas side 26 and accordingly leads to contamination of the Working gas with the fluid. Due to the seal abrasion on the separating element the fluid can also be contaminated accordingly. Furthermore, that is settled fluid in the collection point 12 mixed with the working gas and is available in a foamed form.
- the removal connection 14 is in to introduce the cover 28 by the manufacturer, the constructive Additional effort is low.
- the compensation connection 22, however, is anyway with everyone.
- Container 10 present since it is usually the refill of the Working gas is used, provided this is used, for example, in a piston accumulator via the sealing system of the separating element on the fluid side 24 of the Arrives. Thus, one is already for the compensation connection 22 existing container-side connection used, so that there are no additional costs.
- a shut-off valve 30 is located on the underside of the container 18 arranged, which allows the fluid deposited in the collecting container 18, if necessary together with the dirt from the collection container 18 dissipate.
- On the top of the collecting container 18 is a Whole with 32 designated valve device connected to a first spring-loaded check valve 34 between the extraction line 16 and the collecting container 18 and with a second spring-loaded Check valve 36 between this and the compensating line 20.
- a first spring-loaded check valve 34 between the extraction line 16 and the collecting container 18 and with a second spring-loaded Check valve 36 between this and the compensating line 20.
- a filling and designated as a whole with 38 Test device 38 connected, preferably directly to the compensating connection 22 of the container 10.
- the relevant filling and Test device 38 is not absolutely necessary, but it does Fluid removal process from the container is safer for the operator and more comfortable.
- the filling and testing device can in particular be an actuating spindle 40, which in both directions according to the double arrow representation rotatable an opening or closing process for the compensation connection 22 of the container 10, optionally via a control valve device, for example in the form of a controllable, spring-loaded check valve (not shown). It can therefore be operated using the spindle 40 the filling and testing device 38 carrying fluid to the compensating connection 22 on the gas side.
- a relief valve 42 of the filling and testing device 38 allows the equalization line 20 and must be closed when connecting and operating the removal device.
- the respective pressure conditions can be checked via a manometer 44 of the filling and monitor device 38.
- a throttle point 46 present, especially in the form of an aperture.
- the throttle point 46 from a To form gas filter material, for example made of sintered metal, in such a way Working gas remaining fluid for the return to the container 10 on to clean the compensating line 20.
- Such quick coupling devices 48 are common, so that we will not go into this in more detail here becomes.
- the respective Machine connected to the piston accumulator or the container 10 is to stop.
- the shut-off valve 30 on the bottom of the Collection container 18 closed and the filling and testing device 38 connected the gas-side filling connection of the storage unit, i.e. to the compensation connection 22 of the container 10.
- the next step is the relief valve 42 of the filling and testing device 38 to close and the actuating spindle 40 to a position opening the gas valve.
- the hose-like sampling line 16 is then via the quick coupling device 48 connected to the removal port 14 of the container 10. The connected machine can then be started again become.
- the machine now works again between the pressures P1 and P2, whereby the fluidized gas that accumulates at the collection point 12 has, from the stub of the tapping port 14 and the tapping line 16 into the collection container when the first check valve 34 is open 18 is pushed out.
- the vertically placed collection container 18 then allows the oil components to condense and settle a separation of the transfer mixture in the direction of the shut-off valve 30 and the released gas components can from the collection container 18 as volatile components via the second check valve 36, the compensating line 20 and the filling and testing device 38 the gas side 26 of the container 10 are returned.
- the passing one The separation process is performed by the throttling point used in the direction of the process 46 further reinforced.
- the Oil removal device disconnected again and the collected fluid be drained in the collecting container 18 via the shut-off valve 30, so that the device then again for an oil removal process too is available for other containers.
- the device according to the invention does not need to be used in hydraulic accumulators to be limited according to the application of FIG. 1, but can be used generally for gas-containing containers 10, sofem they have fluid or oil contamination in the gas area.
