Woo Hoo, this is my 1,000 post. Another checkpoint in life.
I installed a complete complement of parts to make my vacuum pump more usable. I pretty much added a kit from JoeWoodWorker and followed his lead. My pump now is on a carrier with a handle and an On/Off switch. This alone would usually be enough for me to celebrate. But there’s more…
I also added a vacuum controller that allows me to dial in the amount of pressure that I want. It is the little black box with the black tubing. It directly turns off the pump. But when you turn off a vacuum pump, you must relieve pressure to the pump, or it will not start again. Hence the Mac valve which is the blue valve sticking out from the front of the pump. It is wired in parallel with the pump. When the pump shuts down, it opens up, and relieves the pressure to the motor through a breather fitting. But there is a check, or one-way valve underneath the Mac value, and a small reservoir out of PVC pipe above it. The reservoir will hold spare vacuum and helps smooth the starts and stops of the motor.
There are two large PVC canisters that I made that hold spare vacuum. These work just like the tank on an air compressor. I also have a gauge and a shut off valve. And I installed a filter to the inlet of the pump.
