3.8.4 CORRECT POSITIONING OF REVERSING GEAR
To position the reversing gear correctly, follow the procedure below:
1. remove the handle (MEC series) or the reversing selector;
2. remove the manifold cover;
3. check that the flat part of the reversing gear is positioned at 45° to the power take-off;
4. re-fit the manifold cover and the handle (MEC series) or the reversing selector.
4 - REVERSION OF DIRECTION OF ROTATION – ROTARY BLADES VACUUM
PUMP WITH FORCE FEED OR AUTOMATIC LUBRICATION
If it is necessary to reverse the direction of rotation of a rotary blades vacuum pump with automatic lubrication, proceed as follows:
- disassemble the back cover and the automatic lubrication pump DX or SX (together with the coupling joint) from the flange;
- remove the screws from the back flange;
- use two screws in the threaded extraction holes until the flange is removed;
- remove the screws from the front flange;
- extract the rotor from the body together with the front flange;
- rotate the body together with the manifold 180° on a horizontal level;
- replace two flange gaskets;
- slide the rotor in the body together with the front flange;
- tighten the six securing screws of the front flange to the body;
- disassemble the bearing and the seeger from the back flange;
- approach the back flange to the pump body, positioning it on a level with the securing holes;
- insert the six securing screws in the holes and tighten;
- assemble the bearing on the flange by means of a stopper and fit the seeger;
- insert the spacer;
- re-assemble the back cover and replace the automatic lubrication pump DX or SX with another one with opposite direction of
rotation (together with the coupling joint) to the flange.
In case of a rotary blades pump
automatic lubrication; while for rotary blades pump
replace the lubrication pump as it is bi-directional.
5.1
WORKING/RUNNING WITHOUT OVERPRESSURE VAL VE – MEC SERIES
Before starting the rotary blades vacuum pump make sure that the hole in the manifold cover made
for the overpressure valve is closed with a cap, if the overpressure and depression valves are present
and working in the installation. If overpressure and depression valves are not fitted on their hole
onto the rotary blades pump, close the hole by means of a cap.
