dismantling of hermetically sealed compressor

U.S. Patent Publication No. But this standard is for motors that are not hermetically sealed with oil and refrigerant. In the embodiment illustrated, the force is applied orthogonally to the plane of the seal, causing the chip to bend as indicated schematically in the Figure inset. 50.000 no scroll compressor,modelsm185s4rc qty. EN. In some embodiments, the bending may be carried out without the aid of a fixture, but precise control may be more difficult to achieve. Privacy Policy The embodiments disclosed above have been generally described, for the sake of simplicity, in terms of a seal that bonds two parts of a chip together around an encapsulated material such that when the seal is subsequently broken, the chip is cleaved in two, exposing the enclosed material. FIG. Each refrigerant compressor seal consists of a metal base, multiple lead-pins, and glass insulation tablets. Alternately, pressure exerted on seal 138 from the pressurized fluid forced out of the secondary chamber 132 may create the desired opening. RPM of motor and compressor … FIG. In some embodiments, the undercuts may have shapes other than the angled wedges shown. Please enter your question. Air Quality Standard: Class I. Voltage: 220/230V. The centrifugal types of hermetically sealed compressor are used for the large units. tmClass . In some embodiments, instead of step 102 as described above, the heat absorption layer may be applied to an area of the facing surface of the second element before it is placed in contact with the first element, forming the chamber. FIG. HOFIM™ hermetically-sealed motor-compressor system 2 Compressor inner casing - upper half Compressor inner casing - lower half Casing cover Compressor outer casing Motor terminal box. Microfluidic chip 150 includes a top substrate 155 and a bottom substrate 160 bonded at hermetic seal 165 to define a chip interior volume. Similar considerations apply to managing materials other than fluids that may need to be encapsulated on a chip, examples including materials comprising sensitive electronics, radioactive substances, medical radioactive substances, biological agents, etc. 5 illustrates one embodiment of a simple apparatus, essentially a fixture 502, including a cavity 504 into which the chip 500 to be unsealed is inserted, and an opening, shown at the front right edge of the Figure, precisely shaped to accept a razor blade 506 and positioned so that the blade 506 can be inserted at a suitable position to stress and break the hermetic seal of interest in the chip. Hermetically sealed compressor: Hermetic compressors. In the embodiments of FIG. It is additionally desirable to provide a method for achieving the controlled release or exposure of the encapsulated materials as and when required. The released material may then be subjected to a mixing process, and/or added to another released fluid. Altogether, this modern design simplifies installation and reduces the footprint 50 to 60% when compared to a conventional compressor. Privacy Policy Horse Power: 5 HP. 1 is a flowchart of process steps for forming a hermetically sealed chamber according to one embodiment. Other at the bottom of the engine and compressor on the top. FIG. hermetically sealed meaning: 1. The first element may be made of glass or another substance that is selected for its chemical inertness with respect to the material to be encapsulated and for its suitability for the room temperature laser bonding technique to be described below. Today, changing products and technologies mean the need is greater than ever for the high quality, reliable compressor seals. Email This BlogThis! The heat absorption layer, typically a thin metal film, used to create the bond, can also be used as a conductive lead, and patterned as necessary around the bond line, such that passing an electric current through the lead creates localized resistive heating which cleaves the bond. FIG. Top substrate 206 is bonded to bottom substrate 204 with one hermetic seal 208 bounding the chamber 202 and another seal 210, which may be hermetic but need not necessarily be so, bounding the perimeter of chip 200. Similarly, the thicknesses of the gaps between bonded substrates shown in these Figures have been greatly exaggerated for clarity. ‘White goods’ in the form of domestic refrigerators and freezers accounts for many millions of hermetic compressors, and the concept can be applied in sizes of up to tens of kW.

COMPRESSOR—The Scroll Compressor Is Hermetically Sealed With Internal High Temperature Protection, And Durable Insulation On Motor Windings. The advantages of room temperature laser bonding most relevant to the present invention arise from its ability to create hermetic seals between elements comprising relatively inert materials such as glass, without the imposition of high temperatures. There is also socket for the electrical connection. - testing the hermetically sealed compressor unit,with its compressor being blocked 517 J. of the finished hermetic compressor - application life test - wear test - endurance test - testing forwarding capability The great number of testing methods and its versatility show the processes within herme­ tic compressors being complicated and complex. Embodiments described herein provide various benefits. 4 illustrates a method of breaking open a hermetic seal around an on-chip chamber according to one embodiment. The manner in which the present invention provides its advantages can be more easily understood with reference to FIGS.
