DIY Vacuum Pump for Bagging RC Plane Wings

Описание к видео DIY Vacuum Pump for Bagging RC Plane Wings

Update: I forgot to install a check valve. When the pump shuts off the reservoir is still at vacuum, so it pulls on the pump internals. This results in air being sucked through the exhaust of the pump, and oil migrating into the vacuum reservoir. After 8 hours of running, my oil level dropped from just below max to right at the min level. Add a check valve between the reservoir and the pump inlet. This is not needed if the pump is run continuously.
