Definitions

• the invention relates to a device for removing fluid from a container which has a gas and which has a removal connection in the region of a collection point for the fluid, to which a collection container can be connected via a removal line and which has a compensation line with a compensation connection arranged on the container is connectable, which is different from the withdrawal connection.

If you want to remove the fluid in question from the container, for example in the form of a piston accumulator, in particular from its gas side, the entire hydraulic system, or at least the part of the system which has the piston accumulator to be serviced and cleaned, must generally be shut down for a long time , In addition to the long downtime of the system mentioned, precise safety regulations must then be observed for the maintenance of the container, which overall makes the maintenance process complex and cost-intensive.

• a relevant object is achieved by a device with the features of claim 1.
• the device is operated in such a way that after its connection, due to the prevailing differential pressures between the container and the collecting container of the device, the fluid, which may contain gas, is discharged from the container and transported into the collecting container.

• a type of closed circuit is realized, which allows permanent operation of the device without it or the like due to unwanted pressure increases. can interfere with the oil extraction process.
• the container Since the compensating connection is already present in every container for a refilling process for gas, the container only needs to be arranged with a removal connection different from the compensating connection at a deep point in the container at which the fluid with the gas collects.
• the device according to the invention can be quickly connected to and disconnected from the container, in particular via quick-coupling devices, so that a removal process takes can take place and the machine downtimes are short.
• a compact design for the overall device can be achieved with a structurally small collecting oil container.
• only a slight gas loss occurs on the gas side of the container compared to the known solutions, since only nitrogen compressed in the fluid, in particular in the form of oil, dissolved nitrogen and in the gas residual space of the collecting container, occurs as a gas loss for the container.
• FIG. 1 shows a connection diagram of the device to a piston accumulator
• FIG. 2 shows a partial representation of a section through a nitrogen bottle with its connections for the connection of the fluid removal device according to FIG.
• the device shown in FIG. 1 serves to remove fluid, in particular hydraulic oil, from a container 10 which contains a gas, in particular in the form of nitrogen gas.
• a removal connection 14 is used, to which a collection container 18 can be connected via a removal line 16, which in turn can be connected via a compensating line 20 to a compensating connection 22 arranged on the container 10, which is different from the mentioned removal connection 14.
• the container shown in FIG. 1 serves to remove fluid, in particular hydraulic oil, from a container 10 which contains a gas, in particular in the form of nitrogen gas.

• FIG. 1 represents a so-called hydraulic accumulator in the form of a piston accumulator with a separating element (not shown), which separates the fluid side 24 from the gas side 26 of the container in the usual way in this type of accumulator, the piston accumulator and consequently the container 10 being held in a horizontal installation position such that the removal connection 14 in the lid 28 of the container 10 is actually on it Gas side 26 opens, in the area of the deepest, that is to say the lowest, point of the store.
• the removal connection 14 is in particular designed in the manner of a stub line which extends through the cover 28 and bends downward at a right angle to the gas side 26 in the direction of view of FIG. 1 and opens there into the gas side 26. This ensures that the fluid removal process actually takes place at the deepest point of the container 10 in the horizontal installation position, the fluid in the form of hydraulic oil settling down due to gravity and collecting at the collection point 12. Between the bend of the stitch-like removal connection 14 and the surroundings, an O-ring is in the cover 28.
• Seal arranged, which seals the lid 28 against the inside of the housing of the container 10. If the oil removal device is used in a piston accumulator, in any case oil continuously flows from the fluid side 24 via the seals of the separating element (not shown) to 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, the settled fluid in the collection point 12 is mixed with the working gas and is thus in a foamed form. The removal connection 14 is in to introduce the cover 28 by the manufacturer, the additional construction effort being low.
• the compensating connection 22 is present anyway in each container 10, since it is usually used to refill the working gas, provided that it reaches the fluid side 24 of the accumulator, for example in a piston accumulator, via the sealing system of the separating element.
• An existing container-side connection is therefore used for the compensation connection 22, so that there are no additional costs.
• a shut-off valve 30 is arranged on the underside of the collecting container 18, which allows the fluid deposited in the collecting container 18 to be discharged from the collecting container 18 together with the contaminants, if necessary.

• a filling and testing device 38 is connected in the compensating line 20 between the collecting container 18 and the container 10, preferably directly to the compensating connection 22 of the container 10.
• the filling and testing device 38 in question is not absolutely necessary, however, makes the fluid removal process from the container safer and more convenient for the operator.

• the respective pressure conditions can be monitored via a manometer 44 of the filling and testing device 38.
• a throttling point 46 is present on the compensating side of the collecting container 18 between the latter and the second check valve 36, in particular in the form of an orifice.
• the throttle point 46 is also possible to form the throttle point 46 from a gas filter material, for example from sintered metal, in order to clean off any fluid remaining in the working gas for the return to the container 10 via the compensating line 20.
• all of the essential components of the device are connected to one another by means of conventional quick-coupling devices 48, which can be separated quickly, as shown in FIG.
• Such quick coupling devices 48 are common, so that they are not discussed in more detail here.
• the shut-off valve 30 on the underside of the collecting container 18 is closed and the filling and testing device 38 is connected to the gas-side filling connection of the store, that is 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 to turn the actuating spindle 40 into a position opening the gas valve.
• the hose-like extraction line 16 is then connected to the extraction connection 14 of the container 10 via the quick coupling device 48. The connected machine can then be started again.
