Definitions
- the present invention refers to a device for sampling working liquids of industrial machines.
- Such type of maintenance provides for foretelling, that is, anticipating and thus avoiding, a failure or a malfunction of a machine by analysing the operating parameters thereof.
- devices for sampling working liquids of industrial machines which comprise a container located below tapping points (usually provided with shutoff valves) formed in the machine.
- the container is then closed and deliverd to a laboratory for analysis.
- sampling devices are known consiting of suitable syringes which aspirate the working liquid from the machine.
- both the tapping devices above described exhibit a major drawback.
- the amount of liquid being withdrawn is generally in the order of 100 cm 3 .
- the significant quantities of foreign material entrained by the working liquid and determining the machine's operation diagnosis that is, the grams of substances (metals, powders, water) per cubic meter of working liquid, are measured in concentrations of few parts per million.
- the technical task of the present invention is to propose an apparatus for making a device for sampling working liquids of industrial machines which overcomes the above cited drawbacks.
- a further object of the invention is to provide a device for sampling working liquids of industrial machines which is of easy and rapid use.
- Fig. 1 is a perspective view of a device for sampling liquids of industrial machines according to the present invention, with some parts taken away for a better illustration of others;
- Fig. 2 is a section taken on line II-II of a portion of the device shown in Fig. 1; and Fig. 3 is a perspective view of the device shown in figure 1 in its whole.
- numeral 1 indicates in the whole a device for sampling liquids of industrial machines, according to the present invention.
- working liquids of industrial machines it is to be meant, in the context of the present invention, those liquids necessary for the operation of machines, for example lubricating oil, refrigerating liquid, and the like.
- the industrial machines may be of any type, including vehicles for motor transport.
- the device 1 comprises a container 2 having an aperture 3 and a closing member 4 engaged with the aperture 3.
- the closing member 4 has the function of fluid-tight sealing the container 2, that is, of inhibiting the transfer of fluid between the external environment and the inside of the container 2.
- the pressure inside the container 2, sealed by the closing member 4 is less than the atmospheric pressure, that is, is less than 101000 Pa.
- the pressure inside the container 2 is between 6000 Pa and 60000 Pa.
- the pressure inside the container 2 is between 8000 Pa and 50000 Pa.
- the pressure inside the container 2 is about 8000 Pa the moment the device 1 is produced and increases slowly over the time until it reaches about 50000 at the end of the period of possible use thereof (which is in the order of few months since the date of production) .
- the container 2 is made from high density PVC.
- the device 1 also comprises a shutoff element 5 that can be switched between a closing position, in which the container 2 is fluid-tight sealed, and an opening position in which the container 2 is put into fluid communication with the external environment.
- the shutoff element 5 is operatively associated with the closing member 4.
- the closing member comprises a screw plug 6 engaged to the aperture 3 of container 2.
- the screw plug 6 encircles and embraces the peripheral edge of the aperture 3 and exhibits a thread pitch of 1 millimeter (see Fig. 2) .
- shutoff element 5 is engaged to the screw plug 6 on the side opposite to the aperture of container 2.
- the shutoff member 5 is a cock of X ⁇ Luer- Lok" type, provided with a valve able to either allowing or inhibiting the passage of fluid between the container 2 and the external environment.
- the cock 5 comprises a first threaded end 7 (Fig. 2) screwed in a threaded hole 8 of the screw plug 6 to provide a tight-fluid seal.
- the opposite end of the first end 7 of cock 5 is provided with a spout 9 intended to receive for engagement a conduit connectable to the machine and from which the liquid to be sampled is to be taken out.
- the device 1 also comprises a lid 10 removably engageable onto the container 2 (Fig. 3) .
- the lid 10 covers completely both the screw plug 6 and the shutoff element 5, so as to make both the shutoff element 5 and the screw plug 6 fully inaccessible.
- the device comprises an RFID (Radio Frequency IDentification) tag 11 holding information related to the container 2.
- ⁇ information related to the container it is intended, in the context of the present invention, one or more of the following: date of production of the container, initial pressure inside the container, expiry of device's utilization, and the like.
- the RFID tag 11 is firmly associated with the container 2, in particular on an outer wall thereof.
- the RFID tag 11 allows a safe and efficient traceability of the device 1, thereby improving stock management, supply orders, and disposal of devices 1 no longer used.
- the device 1 is used as described herebelow.
- the device 1 is connected to the machine from which the working liquid is to be withdrawn for subsequent laboratory analysis.
- the shutoff element 5 is kept in the closing position so as to have the device 1 and the machine phisically connected, but to maintain as well an interruption of fluid transfer. It should be appreciated that, in this configuration, the system device-machine is fluid-isolated from the external environment.
- shutoff element 5 is then shifted into the opening position so as to establish a fluid- connection between the machine and the inside of container 2.
- the container 2 begins then to fill up with the machine's working liquid.
- the shutoff element 5 is shifted into the closing position, thereby cutting off again the communication between the machine and the device.
- the device is then disconnected from the machinery and the lid 10 is applied, so that both the screw plug 6 and shutoff element 5 are not accessible (and the container 2, therefore, cannot be opened, neither accidentally) .
- the device is then delivered to the laboratory for carrying out the necessary analysis on the working liquid taken out from the machine.
- the invention achieves the proposed objects.
- the container 2 is provided with a closing member that isolates it from the outside, and that the pressure inside the same container is below 101000 Pa, in particular ranging from 6000 to 60000 Pa, makes it possible to withdraw working liquid from the machine by avoiding any contamination of the liquid, as clearly appearing from the description of the operation of device 1.
- the device 1 is of easy and rapid use, as clearly appearing from the description of the operation thereof.
