High Pressure Pumping Apparatus

Abstract

A pressure intensifier assembly comprising:—(i) a high-pressure barrel assembly; (ii) pressurizing means; (iii) a first and a second end closure assembly; (iv) a tension frame assembly adapted to resist axial load exerted, in use, along the longitudinal axis of the high-pressure barrel assembly; characterised in that the intensifier assembly further comprises at least one clamping piston adapted to preload the end closure(s) and the high-pressure barrel assembly against the tension frame assembly in order to overbalance anticipated internal end loads.

       4 . A pressure intensifier assembly as claimed in  claim 1 , wherein said pressurizing means comprises a hydraulic ram assembly.  
   
   
       5 . A pressure intensifier assembly as claimed in  claim 1 , wherein the assembly further comprises a stand.  
   
   
       6 . A pressure intensifier assembly as claimed in  claim 1 , wherein the high-pressure barrel assembly is detachably mountable from the intensifier assembly.  
   
   
       7 . A pressure intensifier assembly as claimed in  claim 6 , wherein the high-pressure barrel assembly is detachable from the intensifier assembly without the need to undo a screw thread.  
   
   
       8 . A pressure intensifier assembly as claimed in  claim 1 , wherein at least one end closure is retractable and, once retracted, the assembly is adapted such that the pressure barrel assembly becomes detachable from the intensifier assembly.  
   
   
       9 . A pressure intensifier assembly as claimed in  claim 1 , wherein said assembly further comprises a high-pressure barrel assembly lifting means.  
   
   
       10 . A pressure intensifier assembly as claimed in  claim 5 , wherein the high-pressure barrel assembly is pivotally mounted with respect to the stand.  
   
   
       11 . A pressure intensifier assembly comprising: 
 (i) a high-pressure barrel assembly;    (ii) at least one end closure assembly;    wherein the intensifier assembly further comprises at least one clamping piston adapted to preload the end closure(s) and the high-pressure barrel assembly in order to overbalance anticipated internal end loads.    
   
   
       12 . A pressure intensifier assembly as claimed in  claim 11 , further comprising a tension frame assembly adapted to resist axial load exerted, in use, along the longitudinal axis of the high pressure barrel assembly.  
   
   
       13 . A pressure intensifier assembly as claimed in  claim 12 , wherein the clamping piston acts against the tension frame assembly.  
   
   
       14 . A pressure intensifier assembly as claimed in  claim 12 , wherein the tension frame assembly takes the form of a yoke.  
   
   
       15 . A pressure intensifier assembly as claimed in  claim 11 , wherein the assembly further comprises a first and a second high pressure seal assembly, said seal assemblies being located at either end of the high-pressure barrel assembly.  
   
   
       16 . A pressure intensifier assembly as claimed in  claim 11 , further comprising a pressurizing means.  
   
   
       17 . A pressure intensifier assembly as claimed in  claim 16 , wherein said pressurizing means comprises a hydraulic ram assembly.  
   
   
       18 . A pressure intensifier assembly as claimed in  claim 11 , wherein the assembly further comprises a stand.  
   
   
       19 . A pressure intensifier assembly as claimed in  claim 11 , wherein the high-pressure barrel assembly is detachably mountable from the intensifier assembly.  
   
   
       20 . A pressure intensifier assembly as claimed in  claim 19 , wherein the high-pressure barrel assembly is detachable from the intensifier assembly without the need to undo a screw thread.  
   
   
       21 . A pressure intensifier assembly as claimed in  claim 19 , wherein at least one end closure is retractable and, once retracted, the assembly is adapted such that the pressure barrel assembly becomes detachable from the intensifier assembly.
