PAGE 6 of 6 - Making a Frame for the Compressor
Time to put everything together. After digging into my basement...
|I dag into this pile of wood rests for the frame parts
||These 3 pieces are just what i need
||I used glue and screws to make this frame
The idea is that i will have a threaded rod bended at 90 degrees and use this with nuts to secure the tank vertically:
|This is the bended threaded rod, its an M8. I need two of these
||I measured and marked the positions through which the reds will go through
||And drilled 10mm holes
||You get the idea...
You can't see it but the valve at the bottom of the tank stands about 5mm above the surface. It will be used to empty the tank from water every now and then, so it has to be functional.
Time to put the compressor. I connected the wires from the refrigerator's thermostat to the P-P connections of the pressure switch. Then I fixed the compressor on the chassis with screws. I used the rubber couplings to absorb any vibration.
Note that the output of the compressor goes all the way up and then down again. This route is done on purpose. Refrigerator compressors may lose oil every now and then. This loop prevents this oil (or the majority of it) to go into the tank. It will stay (due to gravity) into the tube and back into the compressor... hopefully...
And one final touch. I got an one-way pneumatic valve and a T connector to get the off-relief work. Here is how it works. The pressure switch has one connection (where the 6mm black hose goes as seen in the following image). This connection is to relief the pistons from air pressure when the motor is not in operation. The air compressor provides the air to the tank through the one-way valve. When the pressure switch turns off the motor, it also opens the exhaust valve. The air pressure inside the motor is relieved but the air pressure inside the tank is maintained due to the one-way valve.
Does it work?
Yeah it does! Its brilliant! Check out the video in the Presentation tab (above)

@Nikos i've got the system but i have not installed it yet.

Has automatic system to turn on while you use it to refill or you turn on manually?

I appreciate your interest to make equipment. Many companies give illustrated explanations about air compressors.

@George Actually, i'm building my pneumatic solder paste dispenser. My next addition will be the smd pick-and-place, for which i already have the pump (USD4) and a manual dispenser (USD 2) which i will hack. Both the solder paste dispenser and the pick and place will be housed under the same box, will have the same foot pedal for operation, and will have a switch to choose which one i currently use.

Het Kam, whilst you are building your smd 'picker', here's a cheap one you could use, looks like it's using a modified fish aquarium pump for the vacuum
HOT in heaven!
