1. The twin-screw compressor improves the machining accuracy of the rotor and makes the rotor gap reach micron level, which can reduce leakage and improve the working efficiency of the compressor. Depending on the application and cooling capacity, there are open twin-screw compressors with large and medium cooling capacities, semi-hermetic twin-screw compressors with small and medium cooling capacities, and micro twin-screw compressors. In the development process of twin-screw compressors, the innovation of screw rotor tooth shapes has played a major role in promoting the development of twin-screw compressors. Starting from the basic requirement that the compressor must maintain good air tightness, the basic pattern of contemporary asymmetric tooth shapes is formed. The twin-screw mechanism of fluid conveying machinery is generally a single left-hand or right-hand screw or rotor, while the twin-screw mechanism used for material processing does not require: On the basis of introducing the classification and working principle of parallel twin-screw mechanisms, it focuses on the parallel twin-screw mechanism. The application of twin-screw mechanism in twin-screw pumps, twin-screw compressors, twin-screw extruders, twin-screw extruders and twin-screw refiners, and their differences, characteristics and working conditions are compared. The work of this paper has a positive effect on the research, design and application of parallel twin-screw mechanisms. Originally produced in food and plastic processing, in recent decades, its application scope has continued to expand and has expanded to fields such as rubber, coatings, petrochemical fibers, building materials, pulp, food, feed processing, and fluid machinery. The core of twin-screw machinery is the twin-screw mechanism. Because the twin-screw mechanism has stronger conveying and mixing capabilities, better self-cleaning performance, and higher efficiency than the single-screw mechanism, it is better than the three-screw and twin-screw sheathed cable material granulator_PE sheathed cable material granulator_Jiudelong ( The multi-screw mechanism above rotary) machinery has obvious advantages of simple structure, so it is widely used. Twin-screw mechanisms can be divided into parallel and non-parallel categories according to the position of the screw axis. Because the parallel twin-screw machine is easy to manufacture, install, and has low cost, it is widely used. This article mainly discusses the main characteristics and applications of parallel twin-screw mechanisms.
2. Parallel twin-screw mechanism The structural form of the parallel twin-screw system varies according to the application field and operating characteristics. According to the steering, it is divided into counter-rotation and co-rotation. According to the meshing form, it is divided into meshing type and non-meshing type. The meshing type is further divided into fully meshed type and partial meshing type. For details on the classification of parallel twin-screw mechanisms, the helical edge of one screw extends into the screw groove of the other screw like a wedge. The material basically cannot continue to enter the adjacent screw groove from this screw groove, but can only It is forced to flow from the groove of one screw to the groove of another screw. As the screw continues to rotate and repeatedly forces the material to turn, the material is subject to better shearing and mixing. This structure has good self-cleaning ability. Geometrically, the screw groove in the meshing area is closed in the transverse direction, or it can be open, but it cannot be closed longitudinally, otherwise it will happen. put one's oar in. That is to say, the width of the screw groove must be designed to be larger than the width of the screw rib to ensure that the longitudinally open twin-screw compressor improves the machining accuracy of the rotor and makes the rotor gap reach the micron level, which can reduce leakage and improve the working efficiency of the compressor. Depending on the application and cooling capacity, there are open twin-screw compressors with large and medium cooling capacities, semi-hermetic twin-screw compressors with small and medium cooling capacities, and micro twin-screw compressors.

The core of twin-screw machinery is the twin-screw mechanism. Because the twin-screw mechanism has obvious advantages over the single-screw mechanism in conveying and mixing capabilities, good self-cleaning performance, and high efficiency, and is simpler in structure than the multi-screw mechanism above the three-screw and twin-screw (rotary) machines, it is widely used. Twin-screw mechanisms can be divided into parallel and non-parallel categories according to the position of the screw axis. Because the parallel twin-screw machine is easy to manufacture, install, and has low cost, it is widely used.

As the screw continues to rotate and repeatedly forces the material to turn, the material is subject to better shearing and mixing. This structure has good self-cleaning ability. Geometrically, the screw groove in the meshing area is closed transversely or open, but cannot be closed longitudinally, otherwise interference will occur. That is to say, the width of the screw groove must be designed to be larger than the width of the screw edge to ensure longitudinal opening.
