Supercharger of air
Arrangement of a supercharger
|
|
When the box for gloves the engine of a supercharger with a wheel of the fan (2) is accessible is dismantled. It is inserted into an air line (1) from below. |
|
|
Here additional resistance of a supercharger (2 – near to a thermosafety lock) are taken out from an assembly aperture in a box (1) superchargers. By arrows lock springs from plastic are shown. |
The engine of a supercharger of air works on four speeds which are established by the rotary switch Giving of air and a 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 a supercharger. Giving плюсового a current (through a safety lock) remains to a constant – only contact to weight "improves or"worsens".
Search of malfunctions in the engine of a supercharger of air
|
|
- If the supercharger of air does not work in one of switch positions check up in the beginning a corresponding safety lock (the table in the head the Electrotechnical equipment).
- If, despite the serviceable switch, screen wipers, the reason in the relay of unloading of H-contact do not work also.
- Check of the engine of a supercharger: completely dismantle a box for gloves (the head Salon).
- Disconnect a bipolar socket in a wire to the engine of a supercharger, connect two auxiliary wires to free now to engine contacts: from accumulator plus to contact to which, and from an accumulator minus the red wire has been connected to contact to which the brown wire has been connected.
- If the engine of a supercharger is perfectly in order, now it should rotate on full speed. If is not present, replace it.
- If the drive works not on all speeds, that, probably, defect in one of resistance.
- Dismantle additional resistance, carry out the visual control. If one of resistance has fused, replace all support with resistance.
- If additional resistance are perfectly in order, along with conductivity infringement in a wire, as a malfunction source still there can be a rotary regulator in a control panel – replace all control mean with heating.

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

Dismantle of additional resistance of a supercharger of air
|
|
- Dismantle a box for gloves (the head Salon).
- Wring out upwards two plastic lock springs below on a fixing payment of additional resistance.
- Raise a fixing payment and take out it downwards. If it is necessary, ослабьте glutinous connection.
- At installation pay attention that the basic payment of resistance is completely densely established in an air line. If it is necessary, condense with its hermetic.
