Supercharger of air

Arrangement of the supercharger

1–case of the supercharger;
2–engine of the supercharger;

3–fan wheel.
In the photo the arrangement of the supercharger in the car with climatic installation is shown.


When the box for gloves is dismantled, the engine of the supercharger with a fan (2) wheel is available. It is inserted into an air line (1) from below.


Here additional resistance of the supercharger (2 – near a thermosafety lock) are taken out from an assembly opening in a box (1) supercharger. Shooters showed lock springs from plastic.

The engine of the supercharger of air works at four speeds which are established by the rotary switch «Supply of air and the supercharger» on a control panel. Various steps of speed are reached at the expense of connection of resistance of different size (or their consecutive connection). Resistance are connected to a wire of weight of the engine of the supercharger. Giving of a plusovy current (through a safety lock) remains to a constant – only contact to weight "improves" or "worsens".

Search of malfunctions in the engine of the supercharger of air

 PERFORMANCE ORDER

  1. If the supercharger of air does not work in one of positions of the switch, check in the beginning a corresponding safety lock (the table in head the Electrotechnical equipment).
  2. If, despite the serviceable switch, screen wipers, the reason in the relay of unloading of H-contact do not work also.
  3. Check of the engine of the supercharger: completely dismantle a box for gloves (head Salon).
  4. Disconnect the bipolar socket in a wire to the engine of the supercharger, connect two auxiliary wires to free now to engine contacts: from accumulator plus to contact to which the red wire, and from an accumulator minus was connected to contact to which the brown wire was connected.
  5. If the engine of the supercharger as it should be, now it has to rotate on full speed. If is not present, replace it.
  6. If the drive works not on all speeds, that, probably, defect in one of resistance.
  7. Dismantle additional resistance, carry out visual control. If one of resistance fused, replace all support with resistance.
  8. If additional resistance as it should be, along with conductivity violation in a wire, as a malfunction source still there can be a rotary regulator in a control panel – replace all control unit with heating.

Dismantle of the engine of the supercharger of air

 PERFORMANCE ORDER

  1. Completely dismantle a box for gloves (head Salon).
  2. The engine of the supercharger is inserted into an air line to heating from below.
  3. Disconnect the socket of a tokopodvodyashchy wire of the engine of the supercharger and take out a wire from an arm.
  4. Lift a lock ledge at the left on the case over a clamp and take out the case of the supercharger of air, having turned it to the left (counter-clockwise).

Dismantle of additional resistance of the supercharger of air

 PERFORMANCE ORDER

  1. Dismantle a box for gloves (head Salon).
  2. Wring out up two plastic lock springs below on a fixing payment of additional resistance.
  3. Raise a fixing payment and take out it down. If it is necessary, weaken glutinous connection.
  4. At installation pay attention that the main payment of resistance is completely densely established in an air line. If it is necessary, condense it with hermetic.
