In the process of shell design of a 100kW single screw expander, the fundamental research on the screw chamber walls thickness is still lacking. Thin wall may cause deformation and the damage possibility of the inlet passage. Thick wall will increase the weight of the expander and led to assembly problem and transportation inconvenience. In this paper, static finite element analysis on cast shell of the 100 kW single screw expander was carried out. By calculating stress distribution and deformation of the expander shell under 1.5 times of the design pressure, the authors find the thickness of gate rotor chamber walls and inlet passage walls as 15 mm is acceptable, but the thickness of screw chamber walls should be at least 35 mm.

Comparison Results

This paper establishes the two-dimensional model, three-dimensional simplified model and three-dimensional of the single-screw pump stators ,and accomplishes their displacement and stress analysis in even pressure inside the stator using ANSYS software. This paper analyzes the comparison results of the combined displacement, equivalent stress and shear stress cloud in the XY plane of single screw pump stator’s three different models. The results manifest the significant differences of the three models for finite element analysis. This study validates that finite element analysis of three-dimensional model leads closer to the true situation.

The Finite Element Analysis

In order to find out the advantages and shortcomings of two line types of three-thread single-screw pump, the comparative analysis method is initially used on the same kind screw pump of different line types .By using ANSYS，this paper adopted the finite element analysis to analyze the deformation、stress and strain of outer equidistant curve of curtate hypocycloid and inner equidistant curve of curtate epicycloids two line types three-thread single-screw pump under uniform pressure and 1MPa differential pressure .It focuses on discussing over the rubber stator of screw pump suffers influenced by the above three factors. The result shows that the existence of uniform pressure makes an uniform radial displacement of the rubber stator; the 1MPa differential pressure makes a great deformation of the rubber stator and the value of stress and strain also increases accordingly, by comparative analysis of two line types of three-thread single-pump, the sealing property of outer equidistant curve of curtate hypocycloid three-thread single-screw pump takes more advantages rather than inner equidistant curve of curtate epicycloids three-thread single-screw pump.

Extrusion screw that is used on market of present extrusion molding catapult is divided by single-axle extrusion screw and multi-axles extrusion screw. Simulation technique of screw that is used in extrusion molding has become so far various. Consist of that analyze third dimension model and that analyze two-dimension model but most Analysis that display dynamic characteristic of screw inside of heat and flow in detail was not until present. Transfer of polymer site that typical single-axle extrusion screw that is analysis target of this treatise is mixed in most melting state is good, but has some controversial points. First melting transfer of balance that is not done difficult. Second melting causes effect that weaken mechanical special quality of screw by power excessive last month if heighten the screw speed to increase amount of done balance. Third Screw dynamic characteristic symptoms by thermal expansion that happen in screw of heater is fallen.

Use of alternate material is always a continuous development in any industry. Such proposals aim at weight reduction, improve life of the components and reduce the components cost. When it comes to the compressor application, there is always a challenge in replacing such parts with polymers, especially on the canopy parts. This study aims at replacing the material of screw compressor canopy with a suitable material with the target of weight and cost reduction, without compromising the functional requirements. Suitable material for the shroud assembly is chosen using the theoretical method and validated using finite element analysis. Suitable process is chosen for the Proto-type shroud from the proposed alternate material (HDPE) and tested in the real-time environment

In this paper, the finite element software was used to analyze the rigidity of the pump body and the rotor shaft, in order to provide some useful information for the optimal design of pump. The analysis result shows that the rigidity of the pump body model is adequate, but the rotor shaft displacement is a little large, which should be modified.
