First, let's introduce the graphite rotor: graphite rotor, suitable for air pump, air pump, high pressure air pump inside the pump core, the operation of the graphite rotor will be thrown out of the blade, then the gas out of the micro air pump; Miniature vacuum pump; Pneumatic motor; The motor; Rubber; Air pump. Miniature solenoid valve; Breast pump vacuum pump; Electric breast pump; Compared with the general charcoal lime graphite rotor (that is, carbon stone rotor or carbon graphite plus surface coating rotor) which is widely used in China at present, the pneumatic motor composite graphite degasser has the following benefits: 1: Aluminum corrosion resistance function can be greatly advanced; 2: make oxidation function forward 6~8 times; 3: make the folding strength forward about 50%; 4: the service life can be advanced 4~5 times
