Embodiment

Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.

As shown in Figure 1, see that from axial direction helical tooth 20 is left-handed rotor toward the upper left side to extension by the bottom right; Otherwise as shown in Figure 2, helical tooth 20 is the dextrorotation rotor toward the upper right to extension down by a left side.

As shown in Figure 3; The utility model opening type double-screw compressor comprises driving element 1, the first one-level mother rotor 2, the first one-level male rotor 3, the first secondary mother rotor 4, the first secondary male rotor 5, first coupling 6, the second one-level male rotor 7, the second one-level mother rotor 8, the second secondary male rotor 9, the second secondary mother rotor 10, second coupling 11, the 3rd coupling 12, tetrad axial organ 13, first 141, second envelope 142 of envelope; Driving element 1 is connected through tetrad axial organ 13 with the first one-level male rotor 3; The first one-level mother rotor 2 and 3 collocation of the first one-level male rotor are installed; The first one-level male rotor 3 is connected through second coupling 11 with the first secondary male rotor 5; The first secondary mother rotor 4 and 5 collocation of the first secondary male rotor are installed; The second one-level male rotor 7 is connected through first coupling 6 with driving element 1, and the second one-level male rotor 7 and 8 collocation of the second one-level mother rotor are installed, and the second one-level male rotor 7 is connected through the 3rd coupling 12 with the second secondary male rotor 9; The second secondary male rotor 9 and 10 collocation of the second secondary mother rotor are installed; First envelope 141 is located at 7, the second envelopes 142 of first coupling 6 and the second one-level male rotor and also is located between the first one-level mother rotor 2 and the tetrad axial organ 13, and first 141 and second of envelope seals 142 in order to carry out rotating shaft sealing.Because the driving element of the utility model opening type double-screw compressor is independent outside at working gas, so become opened compressor.The first one-level mother rotor 2, the first secondary mother rotor 4, the second one-level male rotor 7, the second secondary male rotor 9 are left-handed rotors; The first one-level male rotor 3, the first secondary male rotor 5, the second one-level mother rotor 8, the second secondary mother rotor 10 are dextrorotation rotors, and the profile of tooth Hand of spiral of the profile of tooth Hand of spiral of the profile of tooth Hand of spiral of the first one-level male rotor 3, the first secondary male rotor 5 and the profile of tooth Hand of spiral of the second one-level male rotor 7, the second secondary male rotor 9 is opposite.The first one-level mother rotor 2, the first one-level male rotor 3, the first secondary mother rotor 4, the first secondary male rotor 5 are formed first group rotor, and the second one-level male rotor 7, the second one-level mother rotor 8, the second secondary male rotor 9, the second secondary mother rotor 10 are formed second group rotor.Driving element 1 can be elements such as motor or engine.
