Definitions

  • the invention relates to a lubricating device for lubricating mechanical parts in a high-pressure environment.
  • volume measuring devices which are used in gas pipes through which the gas is transported under a high pressure
  • the mechanical parts of a volume measuring device therefore have to be well lubricated so as to flush dirt out of the bearings and to minimize friction.
  • This supply of lubricant runs out as a result of, among other things, pressure changes in the natural gas pipe. The pressure changes draw the lubricant out of the bearings and therefore the supply, whereafter it is carried away in the gas flow.
  • a lubricating device which comprises a lubricant reservoir and lubricant level control means for varying lubricant level as desired between a first, high level and a second, low level.
  • the lubricant level can be controlled by the lubricant level control means so that, as desired, the parts for lubricating can either be brought into contact with the lubricant or not. This prevents the mechanical parts being in continual contact with the lubricant. Lubricant usage is thus reduced.
  • the lubricating device comprises splashing means for splashing lubricant upward from the first lubricant level.
  • the splashing means When the lubricant level is brought to the first high level, the splashing means will pass through the lubricant and thus splash the lubricant around, whereby the mechanical parts are lubricated.
  • the splashing means preferably comprise a driven splashing vane.
  • the lubricant level control means comprise an object displaceable into the lubricant.
  • This object has a certain volume, and because the object is placed in the lubricant it will displace lubricant, whereby the lubricant level will be raised.
  • Such an object can for instance be arranged eccentrically on a shaft extending outside the high-pressure environment, so that the object can be easily rotated from outside in order to place the object as desired in or out of the lubricant. Translation is of course also possible as well as rotation.
  • the lubricant level control means comprise a displaceable wall part bounding the lubricant reservoir.
  • the content of the reservoir can thus be varied with the wall part, which is preferably embodied as a piston, as a consequence of which the lubricant level can be adjusted.
  • an equally high pressure prevails on both sides of the piston.
  • the invention further comprises a device for measuring the volume of a fluid, which device comprises:
  • a lubricating device for lubricating at least the mounted shaft . It is precisely in such a device that it is of great importance that the mounted shaft remains properly lubricated so as to minimize measuring errors resulting from increased friction in the device. It is furthermore important in such a device that it can operate for some considerable time without any maintenance. Because a lubricating device according to the invention is applied, lubricant usage is less than in prior art devices.
  • the lubricant reservoir a first chamber arranged outside the housing and a second chamber arranged in the housing, which chambers are mutually connected by at least one line. It is thus readily possible to check on the outside of the device whether there is still sufficient lubricant available in the reservoir.
  • the reservoir can thus be provided with for instance a sight-glass. The simplifies checking, and refilling of the lubricant reservoir can be carried out without the device according to the invention having to be disassembled.
  • the lubricant level control means are arranged in the first chamber. This also simplifies construction, since for instance an operating shaft for the lubricant level control means does not have to extend wholly into the device, but only into the first chamber.
  • Figure 1 shows in perspective view and with partly cut-away parts the volume measuring device according to the invention.
  • Figure 2 shows a perspective view of a part of the device of figure 1.
  • Figures 3A and 3B show the device of figure 1 in perspective view and with cut-away parts, wherein the lubricant level is shown in two different positions.
  • Figure 4 shows a second embodiment of a measuring device according to the invention in perspective view and with partly cut-away parts.
  • Figures 5A and 5B show the device of figure 4, wherein the liquid level is shown in two different positions.
  • Figures 6A and 6B show a third embodiment of a volume measuring device according to the invention having mounted thereon an embodiment of a lubricating device according to the invention.
  • Figure 7 shows the volume measuring device of figure 6 with another embodiment of a lubricating device according to the invention.
  • FIG. 1 shows a first embodiment of a volume measuring device 1 according to the invention.
  • This device 1 has a housing 2 with two flange parts 3,4. Using these flange parts 3,4 the volume measuring device 1 can be arranged in a pipeline under pressure.
  • Impeller 5 is arranged in housing 2, which impeller 5 is mounted in a bearing housing 6. Protruding from this bearing housing 6 is a shaft 7 which is coupled to impeller 5. This shaft 7 can for instance be coupled to a detector in order to measure the number of rotations of impeller 5.
  • the measuring device 1 of figure 1 is shown with partly cut-away parts.
  • Impeller 5 is mounted on a shaft 9 which is mounted in a first bearing 10 and a second bearing 11.
  • Shaft 7 is connected to shaft 9 by means of two bevel gear wheels 12,13.
  • a splashing vane 14 is further arranged on shaft 9.
  • a body 15 is further arranged rotatably on a shaft 16, which can be rotated by means of operating shaft 19 by means of a toothed wheel 17 and a pinion 18.
  • the body 15 is rotated by means of operating shaft 19 such that body 15 is wholly immersed in lubricant 20.
  • the liquid level is hereby raised, so that splashing vane 14 passes through the lubricant and thus causes lubricant to splash upward so as to lubricate bearings 10 and 11 and bevel gear wheels 12 and 13.
  • FIG 3B shows a second embodiment 30 of a device according to the invention. This device corresponds for the most part with the device 1 of figures 1-3. Corresponding parts are therefore designated with the same reference numerals .
  • a part of lubricating device 31 can be seen on the outside of housing 2.
  • Lubricating device 31 has a first chamber 32, which is connected via a line 33 to the second chamber present in lubricating housing 6.
  • a return line 34 is provided to equalize pressure differences between first chamber 32 and second chamber 6.
  • first chamber 32 is a rotatable body 35, the rotation shaft of which protrudes through the wall of first chamber 32.
  • a sight-glass 36 is further provided in chamber 32 to allow monitoring of the lubricant level.
  • a filling nipple 37 is further provided to enable the lubricant level to be maintained.
  • FIG 5A the body is rotated such that it is immersed in the lubricant, thereby raising the lubricant level.
  • Figure 5B shows the situation in which the body 35 is rotated out of the lubricant and the lubricant level is brought to a low level, whereby no further lubricant is used in the second chamber.
  • FIGS 6A and 6B show a device 40 for measuring volume.
  • This device 40 has an inlet opening 41 and an outlet opening 42. Along these flows the gas whose volume has to be measured.
  • Device 40 has a housing 43 in which are arranged two rotors 44 and 45. These rotors 44 and 45 are arranged relative to each other and relative to housing 43 such that they completely seal the passage between inlet 41 and outlet 42.
  • Rotors 44 and 45 are mutually coupled by means of synchronization wheels 46 and 47 such that rotors 44 and 45 are rotated exactly 90" relative to each other. It is important to keep these synchronization wheels 46 and 47 well lubricated in order to minimize wear.
  • a splashing vane 49 is arranged on the shaft 48 of rotor 45. This splashing vane 49 rotates as a result of air flowing in via inlet 41.
