High-temperature adjusting control system of multi-stage dry vacuum pump

The invention discloses a multi-stage dry vacuum pump high-temperature adjusting control system which comprises a multi-stage dry vacuum pump body (1), a plurality of temperature detection sensors (2) are arranged in all stages of shells of the multi-stage dry vacuum pump body (1) respectively, and heaters arranged on a pump body heating device (3) are fixed to all stages of surfaces of the multi-stage dry vacuum pump body (1) respectively. The pump body heating device (3) and the temperature detection sensor (2) are both electrically connected with the temperature control system (4), and the temperature control system (4) controls each stage of rotor to be heated according to the detected temperature near each stage of rotor, so that the temperature detected by the temperature detection sensor (2) reaches a set value, and the temperature in each stage of cavity is kept consistent. Accurate temperature control of the rotors at all stages can be achieved according to temperature changes in the cavity, and the
