for WPT, KTS, KPS, KTM, WSM series use and maintenance
the special screw located on the front of the shaft. The driven pulley may be fitted directly on the cylindrical shaft trying to bring
the radial load close to the bearing. Never transfer axial loads. Then connect the driven pulley to the driving pulley with the correct
length of transmission belts. The number and the type must be calculated according to the power to be transferred to the Rotary
blades vacuum pump. When this operation has been completed, the necessary guard must be installed to isolate the transmission
parts (pulley and belts) and prevent operator access to them.
The tension of the belts should be such that when they are tend they can be stretched further by approximately 2 cm.
An exceeding belt tension may cause the breakage of the shaft.
- The ideal tension is the lowest tension at which the belt does not slip under maximum load conditions.
- Check tension frequently during the first 24/48 hours of running in.
- A over tension reduces the belt and the bearing life.
- Keep belts free from extraneous materials that may cause slippage.
- Periodically check the transmission. Tend it when it slips.
To control a conventional transmission tension, use the following procedure:
- Measure the length of free section, t.
- At the center of the free section (t) apply a force (perpendicular to the free section) as needed to flex the belt 1.6 mm by 100 mm
length of the free section. For example, the flexion of a 1000 mm free section will be 16 mm.
- Compare the applied force, measured with a tensiometer, with the values given in the table. If the force is between the "min.
strength" values of the transmission is under tension. If the force exceeds the "maximum force" value, the transmission is tenser
than it should be.
However, a new transmission can be initial stretched twice the value of "min. strength" to allow normal tension adjustment while
operating.
WPT, KTS, KPS SERIES
Then connect the Intake/Compression pipe of the tank to the Rotary blades vacuum pump tightening it to the adjustable elbow using
metal camping bands in relation to the diameter of the pipe.
KTM, WSM SERIES
Install the suction conduit, connecting it to the suction passage of the Rotary blades vacuum pump by means of flange DIN 100/
PN 16 for KTS and KTM 1200-1500 versions and DN 150/PN16 for KTM 1800-2300 and WSM, so that it rises towards the
vehicle. It is also advisable to fit, at the lowest point, a safety container with discharge tap for the evacuation of condensation, to
prevent the formation of rust inside the body. The containers for condensation discharge should be checked especially when external
temperatures are low as ice may form.
Then install the delivery conduit, connecting it to the delivery passage of the Rotary blades vacuum pump by means of flange DIN
100/PN 16 for KTS and KTM 1200-1500 versions and DN 150/PN16 for KTM 1800-2300 and WSM. Also for this installation, it is
advisable to fit, at the lowest point, a safety container with discharge tap for the evacuation of condensation.
