We have a small home machine uses:
-mini air pump, (varies with the equipment model 2-40 L/m)
-a venturi spray nozzle
- a microprocessor with some control circuitry.
We generate a very fine spray of oil/air mixture using spray nozzle; however the mixture has a fixed oil/air ratio.
Need a design where we can automatically control the oil intensity in the mixture to a pre-programmed setting, which changes during the weekdays. providing air flow of the pump remains constant.
We have tested varying the pump speed, this varies the oil suction pressure inside the venturi , also the amount of oil consumed per min , but the air flow is also redused.
We have also tested adding a separate air blower at the final stage (after the nozzle) , but we do not believe this is an ideal solution.
You do not have to design the electrical control, but only the mechanical. As we can provide a control signal as required.
All the items above are used in small home equipment, so small size is essential.
We can provide more details over chat.
You need to have a proven experience in mechanical design, venturi , and product design.
Components of this design shall be custom manufactured or sourced.
A proof of concept is enough at this stage; we will proceed to the full product design project if the design is successful.
Deliverables: this is a proof of concept, so you will be responsible to provide what is necessary to prove that this design actually works , at reasonable cost, and your test results.
we will also need to test the design at our end.
If you have any questions, please ask first before you jump to conclusions and bid.
