Definitions

  • the invention is intended to simplify leakage detection process on vehicles and other mechanical and hydraulic units.
  • a common device for monitoring leakages on crankshaft oil passages [1] consists of a medium feeding system in the form of a hydraulic control valve coupled with a time relay and a control system.
  • the device contains pipe-lines connecting the inlets and the outlets of the oil galleries coupled with the pipe-lines of the pressure relay and throttles whose opening are adjusted for the size of admissible leakage. For identifying a leakage spot in the crankshaft each choke plug is monitored by registering pressure drops in the length of the shaft.
  • Another leakage detection devise includes a vacuum chamber suction cup tightly enclosing a sheet of porous material [2].
  • the vacuum processing system is connected with the upper cavity between the suction cup and the sheet.
  • the device is installed on the surface of a tested unit through which test gas is fed. The leakage is detected by presence of the test gas on the surface. If the unit is leaking, the device is removed and the coordinates of the leakage spots are determined with manual probes.
  • Such device is also quite expensive as it requires complex vacuum and gas monitoring equipment. In addition, it requires specialized space for its operation which adds to the process' costs. Our task is, thus, to create a device that would allow both simplify the leakage detection process as well as make is cost effective.
  • the test map for detecting leakages of operating fluids on transportation units is made as a porous cloth.
  • the face side of the cloth contains schematic vehicle's systems parts layout as well as an indicator of the vehicle's position in relation to the scheme.
  • the test map for detecting leakages of operating fluids on transportation units is made as a porous cloth.
  • the face side of the cloth contains schematic vehicle's systems layout as well as an indicator of the vehicle's position in relation to the scheme while the back side is covered with waterproof film.
  • the test map for detecting leakages of operating fluids on transportation units is made as a plastic / rubber or any other kind of reusable and/or washable materials containing the same as variant 1 or variant 2 layout but specifically designed for repeat usage and miscellanies usage, i.e. garage floor mat, drive-way cover, etc. Cloth may be impregnated with chemical tracers as well as contain a coordinate grid.
  • the markings on the cloth made in accordance with the layout of the tested units permit to obtain accurate information not only about the presence of leaks but also about the location of the leakage spot.
  • the vehicle position marks allow for easy positioning of the tested unit over the map.
  • Waterproof film on the back of the cloth provides protection of the testing room floor.
  • Paper material of the testing cloth with liquids' absorption being among its natural properties allows to significantly reducing the costs of testing procedure.
  • Application of chemical tracers to the coordinate grid increases testing accuracy as it allows diagnosing several units simultaneously as well as determining the type of leaking fluid therefore precisely identifying its source. As a result, greater testing accuracy is attained.
  • the procedure is illustrated by the following drawings: - fig. 1 , test map with the markings corresponding to the layout of the tested vehicle's parts, general view; fig. 2, test map with the coordinate grid; fig. 3, installation of a motor vehicle in the control position.
  • the test map is made as a cloth 1 of porous material.
  • markings are made corresponding to the layout of the tested units, for example, radiator 2, hydraulic booster system 3, oil filter 4, braking system 5, transmission 6, hydraulic booster tank 7, etc.
  • Markings 8 are applied to the cloth 1 determining the position, for example, of the wheels 9 of the vehicle 10 undergoing diagnostics.
  • the cloth 1 is impregnated with chemical traces in the markings places 2, 3, 4, 5, 6, 7, etc.
  • Cloth 1 is containing a coordinate grid 11. Cloth 1 is containing waterproof film (not shown) on the back surface.
  • the diagnostics is carried out in the following way:
  • test map is laid onto a flat surface, for example, room floor.
  • Vehicle 10 is placed onto the map so that the position of the wheels 9 coincides with the gauge markings 8 on the cloth 1.
  • stains appear on the cloth according to the locations of which, as well as their dimension and color, accurate information is obtained about the unit in question.
  • a waterproof film is applied to the back of the cloth.
  • test map may contain markings corresponding to any vehicle make and model as well as concise description of possible leaks and recommendations on further actions.
  • test map may obtain complete and accurate information on the vehicle's condition.
  • the map allows to detect not only presence of leaks, but also their nature and location.

Abstract

L'invention concerne des diagnostics de vérification de fuite, en particulier pour déterminer la source et l'intensité des fuites de fluide de travail sur les unités de transport. Selon une première variante, on décrit une carte d'essai de détection des fuites de fluide de travail sur les unités de transport, cette carte étant en tissu poreux. La face avant du tissu présente une configuration schématique des éléments de système d'un véhicule, et un indicateur de la position du véhicule par rapport au schéma. Selon une deuxième variante, la face arrière est recouverte d'un film imperméable à l'eau. Selon une troisième variante, la carte d'essai pour la détection des fuites de fluide de travail sur les unités de transport est en plastique/caoutchouc ou tout autre type de matériau réutilisable et/ou lavable ayant le même agencement que dans les deux premières variantes, mais avec une conception spécifique pour usage répété et usage divers, à savoir comme tapis de sol de garage, revêtement de sol d'allée pour véhicules, etc.
