摘要:
A wear-resistant article, for example a rotor vane for a pump or compressor, is made by injection moulding and comprises a matrix of liquid crystal polymer (eg a thermotropic poly(aromatic ester)) in which a solid lubricant such as graphite and fine particles of a petroleum or like coke are distributed.

Provided herein are passive microfluidic pumps. The pumps can comprise a fluid inlet, an absorbent region, a resistive region fluidly connecting the fluid inlet and the absorbent region, and an evaporation barrier enclosing the resistive region, the absorbent region, or a combination thereof. The resistive region can comprise a first porous medium, and a fluidly non-conducting boundary defining a path for fluid flow through the first porous medium from the fluid inlet to the absorbent region. The absorbent region can comprise a fluidly non-conducting boundary defining a volume of a second porous medium sized to absorb a predetermined volume of fluid imbibed from the resistive region. The resistive region and the absorbent region can be configured to establish a capillary-driven fluid front advancing from the fluid inlet through the resistive region to the absorbent region when the fluid inlet is contacted with fluid.
摘要:
The invention relates to a component with a coating (5), wherein the component is a part of a wind turbine, the component is in contact with a lubricant (4) and the lubricant (4) comprises atomic hydrogen. The coating (5) covers at least partly the surface of the component. The coating (5) reduces diffusion of the atomic hydrogen into the component by means of inducing a recombination of the atomic hydrogen to hydrogen gas. The invention furthermore relates to a method of reducing diffusion of atomic hydrogen into a component of a wind turbine by using such a coating (5).

Ice-resistant paint comprising an ice-resistant base component that in turn comprises a main component entailing a high solid paint with a synthetic polyurethane-based binding component dissolved in a main organic solvent, and a hydrophobe component consisting of hydrophobic ice-resistant functional nanoparticles selected from among nanoparticles functionalized with a polymer and nanoparticles functionalized in sol-gel, where the ice-resistant paint comprises a mixture of the main component with a dispersion of functional nanoparticles dispersed in a dispersing composition constituting the main solvent and a dispersant, and forms a base matrix, where the dispersing composition and functional nanoparticles form a dispersion of nanoparticles in which the functional nanoparticles are in the base matrix, and the dispersion of dispersing nanoparticles mixed with the main component to form an ice-resistant base component of the ice-resistant paint.
摘要:
Compressor bodies (1, 2), an accelerator (3) and a main motor (4) are disposed on a base (21), while an intercooler (5), an aftercooler (6), an oil cooler (7) and a coolant cooler (8) are disposed perpendicular to the axial direction of the motor (4) so that the directions, in which the tube nests of the gas coolers (5, 6) are drawn out, are made to be the same. A control panel (11) having a maintenance display is mounted on a front panel (52) composed of panel portions (52a, 52b) which are mounted pivotally around respective remote or opposite side ends. Portions to be inspected daily are disposed near the front panel (52) and one side panel (54) adjacent thereto.
