Embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
As shown in Figure 1, 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 dextrorotation rotor toward the upper right to extension by the lower-left.
As shown in Figure 3, open-type double screw decompressor of the present invention comprises generator 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, the 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, the second coupling 11, the 3rd coupling 12, tetrad axial organ 13, generator 1 is connected by 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 by the 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 by the first coupling 6 with generator 1, the second one-level male rotor 7 and 8 collocation of the second one-level mother rotor are installed, the second one-level male rotor 7 is connected by the 3rd coupling 12 with the second secondary male rotor 9, and the second secondary male rotor 9 and 10 collocation of the second secondary mother rotor are installed.Because the generator of open-type double screw decompressor of the present invention is independent outside at working gas, so become the opening type decompressor.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 first one-level male rotor 3, the first secondary male rotor 5 is opposite with the profile of tooth Hand of spiral of the profile of tooth Hand of spiral of the second one-level male rotor 7, the second secondary male rotor 9.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 form the 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 form the second group rotor.
The working principle of open-type double screw decompressor of the present invention is as follows: be inflated gas and be inhaled into by one-level screw rod suction port, expanded by the first group rotor, the second group rotor respectively, then discharge decompressor.This structure decompressor can be realized following several application model: one, as shown in Figure 3, and the present invention's two kinds of working medium that expand simultaneously.Such as the first group rotor swell refrigeration agent, the second group rotor expanded air adopts mechanical shaft seal to seal between the first group rotor and the second group rotor, get final product the function that a decompressor is realized refrigerating expander and air expander; Two, as shown in Figure 5, the present invention realizes in parallel the expansion.The first group rotor swell refrigeration agent, the second group rotor swell refrigeration agent, exhaust is received in the same pipe-line system, gets final product the function that a decompressor is realized the parallel connection type decompressor.Three, as shown in Figure 4, the present invention obtains multiple exhaust pressure simultaneously.Two pairs of rotors in the first group rotor are expanded air simultaneously, can obtain higher exhaust pressure, and the second group rotor is only installed primary rotor, can obtain lower exhaust pressure, can reduce like this installing space and save equipment cost.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
