A water lubrication screw type air compressor includes a compressor, an air-loop system and a water-loop system. The water-loop system comprises a water supply device, a first water-loop unit and a second water-loop unit. The water supply device comprises a first water-treatment device to modify the water quality and provide purified water. The first water-loop unit comprises a second water-treatment device to modify water quality and reduce the corrosion of metal components. The second water-loop unit comprises a water filter to remove the impurities in water and maintain the purity of cycling water. Therefore, the water-loop system in the present invention comprises multiple water-treatment devices and filters to maintain the water quality. The purified water ensures better cooling, lubrication and airproofing when injected into the compressor.

Silica particles are often found in sintered 17-4PH stainless steels when water atomized powder is used. To eliminate the SiO 2 particles and to improve the mechanical properties and corrosion resistance, graphite powders were mixed in this study with 17-4PH powders and binders during the kneading step of the powder injection molding process. The measurements of carbon and oxygen contents in tensile specimens and microstructure observations confirm the reduction of silica particles by graphite powders during vacuum sintering. The optimum content of the graphite addition is 0.26 mass%, with which most SiO 2 particles are reduced and the final carbon and oxygen contents are 0.03 and 0.01 mass%, respectively. These changes of compositions decrease the amount of δ-ferrite in the as-sintered compact to 4 vol%, lower than the 10 vol% of the compact without any graphite additions. After solutioning and aging treatment, the hardness, tensile strength, and ductility are HRC 41, 1310MPa, and 9.0%, respectively. These properties are better than the typical values of 17-4PH reported in the literature and the corrosion resistance remains similar to that without any graphite additions. The relevant mechanisms on the changes of these properties are discussed with a focus on the effects of graphite addition on the residual carbon content, fractions of δ-ferrite and martensite, silica amount, and density. ©2010 The Japan Institute of Metals.

A mathematical model and a calculation procedure are proposed in this study to efficiently calculate the temperature distributions in the male and female rotors of the oil-injected screw compressors. The solution of the transient heat conduction problem of the rotors, which is subject to a periodic convective boundary condition and five steady boundary conditions, is obtained by solving the set of Helmholtz equations derived from the partial differential equations for transient heat conduction without internal heat. During the solving process, the periodic convective and the five steady boundary conditions are calculated using the six empirical constants together with the ideal convective heat-transfer coefficient and the ideal steady heat fluxes. The six empirical constants are determined by minimizing the difference between the calculated and measured temperatures of the rotors. The average errors of calculated temperatures at three locations of each of the male and female rotors are 5.45% and 4.85%, respectively. Results indicate that the heat is mainly transferred from the bearings installed on the outlet shaft of the rotors into the screws. Then, the heat is transferred from the screws to the compressed air and the bearings installed on the inlet shaft of the rotors. The temperature gradient in the axial direction is different at different positions along the screw. The results of the sensitivity analysis show that the three empirical constants that are used to calculate the heat convection between the screw and the compressed air, the heat transfer between the rotor and the bearing at the inlet shaft of the rotor and the heat transfer between the rotor and the bearing at the outlet shaft of the rotor, have a stronger impact on the outputs of the mathematical model than the other three empirical constants. The reduced mathematical model, using only the three empirical constants with the strongest impact, can be used in the studies of the temperature distribution in the rotor. The calculated temperature distributions in the screws can be used to estimate the approximate thermal deformation of the screws and thereby improve the screw profiles and the design of the oil-injected screw compressor. © 2011 Elsevier Masson SAS.
