16:04 What is this compressor for?
So. Why did I choose this particular compressor head? Firstly, it does not heat up, because it has powerful coolers and two stages of discharge.
Secondly, a capacity of a thousand liters is enough for me not only for pneumatic tools, but also for all my future projects.
Why didn't I put the engine and compressor head on the receivers, like everyone else does?
Firstly, a large receiver takes up a lot of space. The length of propane cylinders is less than a meter. But it’s difficult to fit an engine and a compressor head weighing one hundred kilograms on a cylinder. Therefore, it was decided to make a compressor with a quick-release receiver. To freely access the compressor, simply unscrew the air supply pipe and four bolts. The frame with the receiver will be removed by one person.
I made the frame with my own hands from a profile pipe. I cut out the supports for the engine and head from a strip 5 millimeters thick.
Made a small upgrade. The drain plug was replaced with a faucet. Most compressors of this type do not have an oil drain thought out. No matter how you drain it, the oil will definitely get under the head and float down the receiver. I couldn’t find a faucet with a suitable thread, so I bought an adapter and a one-quarter faucet. I filled it with oil and installed a neodymium magnet. When changing the oil, unscrew the cap and look at the result - it will be interesting.
Engine 7.5 kW / 3 thousand. rpm At the end of the welding work, I disassembled everything and painted it with three-in-one primer.
The next day I started assembling. All connections that will be under pressure were sealed with silicone sealant.
I made the protective grille from two old heat exchangers from refrigerators. Despite its size, the homemade grill turned out to be quite rigid and fit perfectly. The final touch was the table. On which there is enough space for something. The homemade compressor turned out to be very unusual and interesting. Together, the receivers, grille and table well protect the compressor from damage and foreign objects.
Since I assembled the most discussed compressor with the AEROMAX B2105T head from FoxWeld, in the video I went into some detail about connecting the electrical part.
He offered several options to choose from: RCD, contactor and thermal relay. And also a presostat for 220 V and 380 V
He showed me what and how to connect it with my own hands, and additionally carried out a series of tests.
He explained in sufficient detail and showed how to adjust the emergency valve and pressure switch.
After adjustment, the pressure switch began to start the compressor when the pressure dropped to just under 6 atmospheres and pumped up to just over 8 atmospheres.
Using a gas meter, I calculated the compressor's output per minute. Taking into account the fact that the check valve resets half the atmosphere when switched off, the meter counted 700 liters.
For AEROMAX B2105T it is recommended to make 800 rpm.
Many people wanted to know whether a compressor paired with a homemade soft start could start. I did a couple of experiments. On pulley 160, the engine did not start under load.
On pulley 110, it seemed to try very hard, but it also didn’t start. So friends, no matter how much I want to save money, I will have to fork out the cash and buy a frequency converter.
Why do you need such a compressor?
For pneumatic tools and a plasma cutter, a 600 liter compressor would be enough for me. I assembled the most discussed compressor with the AEROMAX B2105T head from FoxWeld and I want to try not only simple sandblasting of metal. But also the artistic processing of glass with sand. Once upon a time I already sandblasted glass and stainless steel dishes. I still use my mug from the video from five years ago.
Now you know how to make the most talked about compressor with the AEROMAX B2105T head from FoxWeld with your own hands.
