The design of WSSR Series Rotary Piston Vacuum Pump is as like Figure1-1(a), there are composed of the rotor made as eccentric shape, the slide pin, the exhaust valve and the front, back cover.
When the rotor rolls, the air is inhaled into the cylinder through the Inlet port. And this process continues until Figure1-1(b)-④ and the air is started compressing as passing the state of Figure1-1-(b)-④,⑤ After compressing completely (about over 850 Torr ), the compressed air is extruded through the exhaustion valve.
1. Prefer quantity of vacuum
2. Operation condition of solenoid valve
3. Tension condition and superannuation state of belt
4. Temperature of vacuum pump is changed according to usage state but it is generally at 40℃ ~ 80℃ for surface and bearing part
5. Please rotate by itself about 10 minutes before operation in winter
6. Please clean and exchange to confirm oil filter net at any time
