FluidBox – Operation of fluid system
With the NAVIGATOR “i”, an updated FluidBox is located at the WorkZone in the front. With a functional design, the sprayer operator will be able to quickly start the demanded operation.
- Easy operation of the SmartValves
- Control of filling, agitation, spraying and cleaning
SmartValve
All primary functions needed to operate the sprayer when filling chemicals or cleaning have been built into two main valves. These valves are located in the centre of the working zone.
The logically placed handles and the easy-to-read colourcoded icons make the system very easy to understand and operate and greatly reduce the start-up and operation time of the sprayer.
If an optional filling system, either Pump- Filler or FastFiller, is added, an extra suction valve will be used.
Pump
To meet the requirements of bigger sprayers and to improve lifetime, HARDI offers the 464 pump. A reduction in pressure drop has been avoided by improving the flow in the diaphragm tops. To easy service, we have integrated lifting hooks while moving two greasing points to the front, to easy lubrication of the front and the rear of the pump. The casted conrod support ring has also been redesigned for improved mechanical life time. The most visible change is the new covers designed to protect the pump from mud and water getting into the system.
- Self-priming
- Able to run dry without damage
- Easy to service
- Grease-lubricated crankcase
EasyClean filter
The EasyClean filter is a high capacity suction filter. The condition of the filter can be constantly monitored via a SafeSpray vacuum gauge.
This ensures that the filter is cleaned when needed and only when needed. When cleaning the filter, all you have to do is to twist the lid 90°. This will close a main tank valve in the bottom of the filter and open the filter for inspection.
CycloneFilter
The HARDI CycloneFilter is a unique self-cleaning pressure filter that uses a high-speed cyclone for additional cleaning action. The cyclone action increases the cleaning capacity of the filter significantly.
In addition, the CycloneFilter has a unique boost function allowing the filter to be flushed when needed.
Unique cyclone action greatly improves the self-cleaning action
The cyclone created inside the filter increases the speed of the liquid against the filter screen, thereby increasing the effectiveness of the self-cleaning action.
Filter is fitted in an upright position
The filter is fitted in such a position that spill can be avoided when inspecting the filter. This ensures fewer stops and reduced pressure loss in the liquid system.
TurboFiller
The HARDI TurboFiller is developed to handle large quantities of powders and liquids. Its high capacity is achieved through a combination of high vacuum and liquid rotation produced by a TurboDeflector inside the hopper.
High mixing capacity
Liquid at high pressure is being used to create a powerful rotation of the liquid inside the hopper. This movement gives the effect that every powder or liquid chemicals are mixed before they are sucked into the sprayer. The highest capacity is achieved when the TurboFiller is more than half-filled with water.
Optimum filling height
A spring-loaded bracket with transport lock makes it easy to change from field to filling position. The filling position is approx 95 cm from the ground.
EFC boom section valves
The ElectricFastControl (EFC) is a modular system with a positive drive motor valve for each section and a single pressure dump valve, when all sections are switched to OFF.
The section valves incorporate a pressure dump. When the section is switched to OFF, the pressure in the line to the nozzles is relieved.
This results in instant shut-off at the nozzles. The EFC does not need any form of adjustment, e.g. pressure equalisation.
DynamicFluid4 liquid system
Dynamic fluid system based on 4-sensor technology
The fluid system on the ALPHA evo is a new concept developed to obtain shorter response time and thereby more precise application in the field.
New powerful engines on the ALPHA evo and the hydrostatic transmission have given new driving patterns with more variance in the speed and faster acceleration, factors which together with the GPS controlled section control is challenging for the performance of the liquid system. In a traditional fluid system the regulation is made on feedback from what is already “historical” data. For example the RPM is increased, and shortly after the flow will be too high at the nozzle. When that is measured, the spray computer will regulate the pressure down again but in the meanwhile the application rate has been too high.
The DynamicFluid4 system will calculate the consequences of the increased RPM and make the regulation instantly. The DynamicFluid4 property of pro-acting is based on 4 sensors in the fluid system measuring RPM, position of regulation valves, flow and pressure. Together with new software and new unique ceramic regulation valve, DynamicFluid4 is offering precision in the application rate giving the best performance available on the market.
