Garland Maine | There are two pressure senders on the sprayer. One sensor is right above the pump, and one is on the boom plumbing in the middle of the boom tree. If the pump pressure much higher than the boom pressure you may have a plugged filter, or some other restriction. To determine which sender shows on which gauge just unplug one and see which gauge reads zero.
As someone already said the pressure is running right for the o3's. Could be something electrical where a bad connection or sender unit doesn't report 40 psi right, but does report 80 psi right.
You say you are new to Rogators, but have you had a rate controller like the Raven before? These rate controllers don't care about the pressure. They have a flow meter which is next to that green handled knob on back you are fiddling with. The flow meter measures how many gallons go to the booms. The speed sensor (radar) measures how fast you are going. The rate controller takes that information combined with which booms are on and adjusts the pump speed (not pressure) to give you the desired rate.
With that combination you should not try to play with the "throttle valve" or the manual pressure regulator knob. Let the expensive electronics do their job, and you just turn the steering wheel ;)
My opinion is to do a calibration verification on your sprayer, and if the flow meter and radar check out then run it and don't fiddle with too many things.
I could never trust the sticker on the tank gauge to be accurate enough for calibration. Run the sprayer until empty, put in a known quantity of water, and check if the flow meter records it properly.
Take a measured distance and verify the distance travelled.
If both of those check out take a look at your spray pattern and make sure it is spraying evenly across the boom. If the middle nozzle and the end nozzle put the same amount out in a minute than just get to spraying and figure out the pressure mystery some other time. | |
