TRR two-stage series Roots vacuum pump
Detailed introduction
This series of products includes two-stage series Roots blower and two-stage series wet Roots vacuum pump.
Due to reasons such as efficiency and temperature rise, the pressure ratio of a single-stage blower (vacuum pump) is generally limited to 2.2. In order to achieve a higher pressure ratio, two blowers (vacuum pumps) are usually connected in series to form a two-stage series blower (vacuum pump). Among them, the two-stage series Roots blower is equipped with an intercooler between the two stages.
Main technical indicators:
Two-stage series Roots blower flow rate: 0.63～1258m3/min,
Pressure boost: 98～196kPa;
Two-stage series wet Roots vacuum pump flow rate: 1.21～1250m3/min,
Vacuum degree: -53.3～-80kPa.
