5BLOWER GROUP

All the mistblowers have a high speed fan rotor.You must take great care and beware of the effects that this can provoke: such as the aspiration and projection of foreign bodies which, although of a small size, can be very dangerous especially for the eyes and face.

5.1AXIAL BLOWER GROUP WITH PULLEY

The mistblowers that have a drive transmission between the pump and fan with pulleys are equipped with a neutral gear; the multiplied ratio is 1:4.26, the rotation speed of the fan is 2,300 RPM.

You should periodically check the tension of the belts; if they become too slack you should tension them by loosening nuts B and screwing in screws A to take up the slack. Remember to tighten nuts B again after the operation. (FIG.18)

5.2AXIAL BLOWER GROUP WITH MULTIPLIER

The transmission of the drive from the pump to the fan is done through a multiplier with one or two neutral gears.

Normally the rotation speed of the fan is 1950 RPM in first gear and 2500 RPM in second in the multiplier with 2 gear ratios (multiplied ratios 1:3.6 - 1:4.6) and 2,500 RPM in the multiplier with one gear ratio (1:4.6)with the power-takeoff running at 540 RPM.

You can change from one gear to the next with the lever on the multiplier, made accessible through the opening on the side in the rear left part of the machine or at a distance on the right side. The lever has 2 or 3 positions depending on the number of gears and the central position is neutral (to use only the pump without the fan).

WARNING: the gear change lever must only be used with the power-takeoff disengaged and the fan stopped. If it is difficult to engage, turn the cardan shaft slightly by hand to find the right position of the lever (make sure the tractor is turned off).

There are two deflectors (one on the right and one on the left) in the bottom part of the delivery outlet of the fan groups which define the direction of the airflow; lower if the deflector is lowered and higher if the deflector is raised. For the system to work properly it should be set up as follows: the left deflector (looking at the mistblower from behind) raised and the right one lowered in machines with a multiplier, vice versa in those with a pulley (as the fan turns in the opposite direction).

For the maintenance of the multiplier (see point 8.2.3 Multiplier Lubrication).

5.3BLOWER GROUP WITH FRONT SUCTION

These models have front suction with delivery of the air obliquely to the rear of the machine. This characteristic guarantees greater penetration into the vegetation (see fig. 19)

There are two models of blower groups with front suction:

-Axial fan: used for treatments similar to traditional multiplier blower groups, with delivery of the air in a circular crown.

-Tangential fan: for use in small and medium espalier rows of vines. There are pulley drive versions or multiplier versions, adjustable jets can be mounted to spray the vegetation at various heights.

The vanes of these blowers have an inclination that can be adjusted by 5°, with positions from 20° to 40° (as standard this is set at 35°); to adjust the inclination you have to order the appropriate adjustment discs (Fig. 20, page 18). This operation must only be performed by qualified personnel respecting the position of the single vanes so as not to vary the dynamic balance of the fan; unbalanced blowers can cause rapid wear of the multiplier and the fan rotor itself making the machine unsafe.

FIG. 18

WORK TEMPERATURE

Heat is generated by the friction between the various moving components and on the basis of the power transmitted. The temperature

of the multiplier or disengaging box depends on the capacity to dissipate heat to the surrounding environment and therefore the surfaces involved in the heat exchange and the environmental conditions.

The specifications refer to environmental conditions with a temperature between -10° +50°C (14°C -122°F).

The working temperature limit of the box is 90°C (200°F) established to prevent the ageing of the seals and guarantee a sufficient viscosity of the oil. The heat makes the air in the box expand and therefore increases the pressure inside. The correct use of the oil seals is guaranteed up to an internal pressure of 0.5 bar. Boxes designed to be used for particularly heavy duty work are equipped

with a breather cap that can be fitted on any cast iron box on request.
