Definitions

  • Drainage devices are normally connected to Diesel oil filters. There are two types:
  • Manual drainage It is a manual drainage used in standard Diesel engined cars or in yard Diesel motors.
  • seepage in the injection pump may occur ( filling up in a filling station in witch the tanks are notchecked and water is not drained often).
  • the new elctronic device drives a particular high-tightness-electric-pump through one electrode (see CH.7); water located near the electrodes is quilckly expelled by the pump whose start is indicated by a warning light to be placed on the dashboard (in cars without warning light, or connected to the existing lamp to the new device).
  • this device allows to get rid of bulky and expensive separators and ensures prompt water and air expulsion from the bottom of filters.
  • the electronic water detector technique is based on the specific resistance of the water near the the electrode located at about 2-3 mm. from the bottom of the filter. Its resistivity depends on the amount of mineral salts contained in water; it is between 40 and 100 Kohm in waters with many mineral salts, or between 10 and 200 Mohm in waters with fewer mineral salts or in semi-demineralized waters.
  • the electronic circuit and wiring diagram are enclosed with the report (table n.1-illustrations 2-3).
  • the circuit analysis shows that the water resistance between the electrode and earth (Ra) allows the negative bias of T1-T2 (BC212 PNP type) transistors'bases.
  • Ice1- Ice2 output currents trough the resistors R3-R4 bias the power-transistors'bases separetely T3-T4 (BDX53 NPN Type).
  • the two transistors T3-T4 can supply no more than 8A (Ice), but when in conduction, the output current is doubled as they are connected is in parallel.
  • wich may require a starting-current of about 10 A.
  • the pump is monitored by a flashing LED diode (CH.13), while D1 diode protects the electrovalve's coil from overvoltage when T1 and T2 "open” or "close”.
  • a filter prevents the membrane-intake-valve from obstrucion (CH.16).
  • CH.16 obstrucion
  • the new device can be installed with various options; the electronic circuit and the pump can be placed away from the filter.
  • the electrovalve is a part of the filter-plug and this reduces fuel-residue in the connection between the filter and the electrovalve so that only water is expelled.
  • Illustration n°1 shows a description of the device working technique. This drawing represents the partial section of some components (main filter, electrovalve, connections optional filter, pump) whose main elements are:
  • the device works as follows: When water at the bottom of the filter reaches a level of nearly 3 mm. it connects the plug-electrode to the metallic side of the filter.
  • Ra is run by a current that makes T1 and T2 transistors go in conduction; these transistors pilot T3 and T4 respectively.
  • the two collectors are connected both to the electrovalve-coil (I:0,7 A) and to the pump motor-coil.
  • the supply circuit is closed by T3 and T4, the electrovalve opens the water-drainage-pipe and simultaneously the pump starts.
  • the device is very sensitive: a few drops of water drainage can lower slightly the water level around the electrode. Consequently, the previous insulation is restored and in the same time, the electrovalve shuts again and pump motor stops.
