4.8PRESSURE REGULATOR

To use the pressure regulator, follow the instructions in the enclosed handbook scrupulously. The pressure regulator controls all of the most important spraying functions, the thorough knowledge of its functions makes work easier and more precise.

The working pressure and the maximum pressure of the sprayer are determined by the pressure regulator which also protects the circuit from overpressure in any work conditions. (In serious but very rare cases, if the connecting pipes get blocked the pressure relief valve lets the pressure off) In some setups there may be a pump that can reach a pressure of 50 bar controlled by a regulator designed for 20 bar. In this case the maximum pressure that can be reached is 20 bar.

The regulators can be manual, mounted on the sprayer or at a distance to make the controls easier to use; or electrical with a control panel in the cabin. There are also regulator versions with mechanical remote controls with a cable. If the tractor has a waterproof cabin the use of electrical controls is obligatory.

4.8.1 COMPONENTS OF THE PRESSURE REGULATOR

Below you will find the indications for the main models fitted on Unigreen products.

A main ON-OFF command: “open” lets the fluid flow into the circuit in use; “closed” empties the tank.

B maximum pressure valve: adjusted by hand with the relevant knob (drains the excess liquid when the set pressure is reached).

C boom section tap: opens the corresponding boom or drains to the compensation regulator (G).

D auxiliary tap: can be used for various accessories (it is always manual). E volumetric pressure valve (proportional):

(when present) it regulates the spraying pressure. The valve automatically compensates variations in speed (within the scope of the same gear ratio), keeping the quantity of liquid supplied per surface unit (litres/hectare) unchanged.

F self-cleaning filter: filters the delivery liquid.

G compensation regulators: suitably regulated, these make it possible to keep the pressure constant when one or more sections of jets is closed, they don’t influence treatments with the boom fully open.

H manometer: indicates the working pressure.

Connections:

R1 supply union

R2 drain union

R3 volumetric drain union

R4 boom section delivery union

R5 auxiliary delivery union

Control box for ERGO and REMO electrical regulators

I1 main control valve switch

I2 volumetric pressure valve switch (proportional)

I3 boom section valves switches

4.8.2 GENERAL INSTRUCTIONS

When using the pressure regulator, scrupulously observe the instructions in the enclosed handbook, below you will find generic indications for the major models fitted by Unigreen.

All the regulation and adjustment tests must be carried out with clean wa- ter.

Pressure regulators without a volumetric valve (GCP3-way - RPN - RVA) Adjusting the maximum pressure valve

=put main control A in the drain position (“OFF”).

=loosen the hand wheel of maximum pressure valve B completely (anticlock- wise).

=start the pump by activating the power-takeoff of the tractor at 540rpm

=open main control A (position “ON”), the manometer will be activated

=open all of the section valves C (position “ON”)

=adjust maximum pressure valve B to the working value (in any case less than the safe maximum pressure the system can reach).

CAMPO 11 - 16 - 22 - 32, DSP 11 - 16 - 22 - 32 specifications

Unigreen DSP Series and CAMPO Series are advanced agricultural sprayers designed to meet the evolving needs of modern farming. The Unigreen DSP (Dynamic Spraying Product) models 11, 16, 22, and 32, along with the CAMPO models of the same specifications, are engineered for efficiency, precision, and reliability in crop protection.

One of the key features of the Unigreen DSP models is their innovative spraying technology. Each model is equipped with a high-capacity tank that allows for extended operation without the need for frequent refills. The DSP series incorporates adjustable booms that provide precise application across various crop types. This ensures uniform coverage and minimizes waste, making it an environmentally friendly option for farmers.

The CAMPO series also boasts similar tank capacities and boom adjustments, making them suitable for diverse agricultural applications. Both series offer customizable options, allowing farmers to choose the configuration that best fits their land and crop requirements.

Another standout characteristic of both Unigreen and CAMPO sprayers is their user-friendly interface. Equipped with advanced electronic controls, farmers can easily monitor and adjust spray rates, pressure, and other critical parameters in real time. This technology not only enhances the sprayers' operational efficiency but also aids in achieving the optimum application rates for different pesticides and fertilizers.

Furthermore, both series integrate cutting-edge GPS technology, enabling precision agriculture practices. This feature allows operators to map their fields, ensuring that every inch is accurately treated, while also reducing the possibility of overlap or missed areas. This precision application reduces chemical usage and ultimately leads to cost savings.

Durability is another primary focus in the design of the Unigreen DSP and CAMPO sprayers. Built with high-quality materials that can withstand harsh environmental conditions, these sprayers promise longevity and consistent performance over time.

In summary, Unigreen DSP and CAMPO models 11, 16, 22, and 32 are technologically advanced agricultural sprayers that combine efficiency, precision, and durability. With features such as adjustable booms, advanced electronic controls, and GPS technology, they cater to the diverse needs of today’s farmers, helping to enhance productivity while minimizing environmental impact. These sprayers are positioned to play a pivotal role in the future of sustainable agriculture.
