Description
- This application is a continuation of U.S. patent application Ser. No. 12/451,447, filed on Nov. 30, 2009, and entitled “Frame for Fluid Machines,” which is a §371 application of International Application Serial No. PCT/IB2008/001205, filed on May 9, 2008 and entitled “Frame for Fluid Machines,” which claims priority to Italian Patent Application Serial No. MI 2007 A 001000, filed on May 17, 2007. The content of these applications is incorporated by reference herein in its entirety.
- The present invention regards the fluid machines and, more in particular, it refers to a frame for reciprocating compressors.
- As known, a compressor is a special kind of machine capable of exploiting the task performed by an engine to increase the pressure of a compressible fluid (gas or vapour). In reciprocating compressors, the compression of the fluid is performed by one or more moving pistons with reciprocating movement within a respective cylinder. The fluid to be compressed is suctioned into the cylinder by a suctioning pipe, while the compressed one is ejected from the cylinder towards a discharge pipe. Usually, the piston or pistons of a reciprocating compressor are operated by electric motors or by internal combustion engines through a crankshaft for transmitting drive and a traditional connecting rod/crank mechanism.
- The industrial reciprocating compressors are usually provided with an external casing, referred to as frame, whose purpose is to accommodate the connecting rod/crank mechanism and bear the cylinder or cylinders, countering the reciprocating forces generated upon compression of the fluid.
- As of date, the frames for reciprocating compressors, generally made by melting metal and/or machining by means of tool machines, are made up of a single body capable of resisting against the stresses generated during the compression cycle and subsequent to the rotational movement of the driving shaft for transmitting drive to the pistons. Thus each single compressor must be provided with a specific frame depending on the number of cylinders, usually arranged vertically and in a linear manner, with which it is provided. Consequently, it is necessary to design and manufacture each frame separately, substantially increasing both the costs and the production time.
- Thus, the objective of the present invention is to provide a frame for fluid machines, in particular but not exclusively reciprocating compressors, capable of being used indistinctively both on single-cylinder machines and on two or multi-cylinder machines, without requiring different dies to obtain the specific frames depending on the number of cylinders of the machine.
- Another objective of the invention is to provide a frame for fluid machines capable of facilitating and quickening the assembly of the machine with respect to known art.
- Still, another objective of the invention is to provide a frame for a fluid machine capable of allowing reduction of costs and production time as well as storage in the warehouse.
- These objectives according to the present invention are attained by manufacturing a frame for fluid machines, in particular but not exclusively reciprocating compressors, as described in claim 1.
- Further characteristics of the invention are outlined by the subsequent claims.
- Characteristics and advantages of a frame for fluid machines, in particular but not exclusively reciprocating compressors, according to the present invention shall be clearer from the following exemplifying and non-limiting description with reference to the schematic drawings attached wherein:
-
FIG. 1A is a top plan view of a frame for fluid machines according to the present invention, applied to a single-cylinder reciprocating compressor; -
FIG. 1B is a sectional view obtained along line A-A ofFIG. 1A ; -
FIG. 2A is a top plan view of a frame for fluid machines according to the present invention, applied to a two-cylinder reciprocating compressor; -
FIG. 2B is a sectional view obtained along line A-A ofFIG. 2A ; -
FIG. 3A is a top plan view of a frame for fluid machines according to the present invention, applied to a four-cylinder reciprocating compressor; -
FIG. 3B is a sectional view obtained along line A-A ofFIG. 3A ; -
FIG. 4 is a side elevation view of a frame for fluid machines according to the present invention; and -
FIG. 5 is a side elevation view of a frame for fluid machines according to the present invention, on which one or more cylinders of fluid machines of a reciprocating type are vertically mounted. - Referring to the figures, schematically shown is a frame for fluid machines, indicated in its entirety with
reference number 10 and applied as an example to a vertical reciprocating compressor for compressible fluids, which can be used in any gas compression station or system. - The
frame 10 is provided to bear one ormore cylinders 12, moving inside each of which, with a reciprocating movement, is a piston (not shown); operated by acrankshaft 14. The fluid to be compressed is introduced into eachcylinder 12 through one of more suctioningpipes 18, while the compressed fluid is ejected from thecylinder 12 itself towards one ormore discharge pipes 18′. - According to the invention, the
frame 10 is made up of one ormore modules 20 of the same shape and size, within eachmodule 20 being provided asingle chamber 16 adapted to accommodate the crank mechanisms of eachsingle cylinder 12. In addition, eachmodule 20 is provided with a pair of substantially flatopposite side walls more fixing means 26 which allow rigid coupling to each other, adjacently arranging their respective side walls, of two or moreidentical modules 20 to provide aframe 10 for compressors provided with two ormore cylinders 12, as shown for example inFIGS. 2A , 2B, 3A and 3B. - In the embodiments illustrated the fixing means 26, preferably made up of bolts of the known type, are inserted into
suitable holes 26′ made on eachside wall module 20, thus allowing to arrange themodules 20 themselves adjacent to each other in such a manner to provideframes 10 for reciprocating compressors provided with two cylinders (FIGS. 2A and 2B ), three cylinders, four cylinders (FIGS. 3A and 3B ) and more, without any restriction regarding the number of cylinders. - In such manner, it is possible to adapt the
frame 10 according to the invention in a flexible manner to various types of reciprocating compressors, both with one or more cylinders, without requiring different frames depending of the number of cylinders of the machine. - Each of the
identical modules 20 making up theframe 10 according to the invention can be made according to methods known to the industry, for example through melting metal (cast iron) or through machining by means of tool machines. In order to facilitate the coupling of themodules 20 in case of multi-cylinder compressors, made on one of theside walls 22 of eachsingle module 20 can be at least one shapedportion 28 which is inserted in a shape-coupling manner into a respectiveshaped portion 30 provided on theother side wall 24 of theadjacent module 20. Due to the minimum clearance between theshaped portions pins 32 fitted onto theside walls fixing bolts 26 and the friction forces generated between theadjacent walls adjacent modules 20, themodules 20 of theframe 10 are capable of efficiently resisting, when coupled to each other, against the forces generated during the operation cycle of the compressor just like the case single-block frames according to the known art. - Furthermore, each
module 20 is provided, on each of itsside walls circular hole 34 which allows the passage of thecrankshaft 14 and possibly one or more rotating countershafts, if present on the compressor. In order to prevent excessive flexure stress of thecrankshaft 14 during the operation of the machine there can be provided one ormore support plates 36 which can be inserted into theholes 34. Thesupport plates 36 of thecrankshaft 14 are fixed into theside walls module 20 by means of a plurality ofbolts 38. In addition, when themodules 20 are coupled to each other to provide aframe 10 adapted to supportmore cylinders 12 and, consequently, when theholes 34 of themodules 20 adjacent to each other are connected to each other to allow the passage of the crankshaft 14 (FIGS. 2B and 3B ),support bearings 40, inserted into theholes 34, can be provided to support thecrankshaft 14 itself. - It has thus been observed that the frame for fluid machines, in particular but not exclusively reciprocating compressors, according to the present invention attains the objectives outlined previously. In detail, the use of a single metal module made from a single die allows to provide, in an easy and quick manner, modular frames for machines with any number of cylinders. This occurs simply by assembling a number of modules corresponding to the number of cylinders of the machine to each other.
- The frame for fluid machines, in particular but not exclusively reciprocating compressors, of the present invention thus conceived is in any case susceptible to various modifications and variants, all falling within the same invention concept; furthermore, all the details can be replaced by technically equivalent elements. In practice, the materials used, alongside their dimensions and shapes, may vary depending on the technical requirements.
- Therefore, the scope of protection of the invention is defined by the attached claims.
