Abstract
The invention relates to a Roots vacuum pump. The Roots vacuum pump comprises a Roots vacuum pump body, shafts and rotors are arranged in the Roots vacuum pump body, the externals of the shafts are provided with the rotors, the upper end of the Roots vacuum pump body is provided with an air inlet, the lower end of the Roots vacuum pump body is provided with an air outlet, additional tuyeres are arranged at two sides of the Roots vacuum pump body, and a cooling device is arranged at the air outlet of the Roots vacuum pump body. The Roots vacuum pump has the advantages of simple structure, use convenience, work temperature reduction, work noise reduction, wide application, reliable running, low maintenance cost, work efficiency improvement, and service life prolongation.
Description
Technical field
The present invention relates to a kind of Roots pump.
Background technique
Roots pump is widely used in the industries such as smelting in vacuum metallurgy is degassed, rolling, chemical industry, food, medicine, use more extensive, traditional Roots pump can exist some problems in the course of the work, Roots pump deterioration phenomenon easily occurs after work a period of time, cause its life-span greatly to shorten, badly influenced the normal operation of Roots pump, for addressing the above problem, the spy provides a kind of new technological scheme.
Summary of the invention
The purpose of this invention is to provide a kind of Roots pump.
The technical solution used in the present invention is:
A kind of Roots pump, comprise the Roots pump body, be provided with axle and rotor in this Roots pump body, described axle outside is provided with rotor, described Roots pump body upper end offers intake grill, described Roots pump body lower end offers exhaust outlet, and described Roots pump body both sides are provided with wind-supplying mouth, and the exhaust outlet place of described Roots pump body is provided with cooling unit.
Described cooling unit is comprised of cooling coil and the fin that is fixed on cooling coil.
The diameter of described wind-supplying mouth is less than the diameter of exhaust outlet.
Advantage of the present invention is: simple in structure, easy to use, reduced the operating temperature of Roots pump, and can reduce its operating noise again, be widely used, reliable, maintenance cost is low, has improved working efficiency, increases the service life.
