Definitions
- the present invention relates to the technical domain of pumps and, especially, of high pressure or very high pressure pumps.
- Such pumps are met, among other activities, in petroleum and related industries and in industrial cleaning industry and in civil engineering. These pumps are characterized in that their powers are very high, usually about 373 000 to 746 000 or 895 200 Joules/s (say, 500 to 1000 or 1200 CV) and in that they must convey very corrosive fluids (such as highly acid fluids) or very abrasive fluids (such as cement slurries for oil well cementing) or also special fluids such as fracturation gels in the petroleum industry, charged with propping agent (sand), and other particular fluids.
- very corrosive fluids such as highly acid fluids
- very abrasive fluids such as cement slurries for oil well cementing
- special fluids such as fracturation gels in the petroleum industry, charged with propping agent (sand), and other particular fluids.
- a pump of this type schematically consists of a "power end" and a “fluid end".
- the power end comprises all the elements which are necessary for the piston displacements, and the piston.
- the fluid end is a very high pressure end which schematically consists of a body forming the piston chamber, with its inlet valve and outlet valve, and a fluid discharge element.
- the chamber comprises one (or several) inlet valve and one (or several) outlet valve.
- valves are placed at the end of the chamber opposite to the free end of the piston.
- the present invention is a determining improvement of such a type of "in line" fluid end.
- the Fig. 1 shows prior art "in line” fluid ends.
- the Fig. 2 shows a preferred embodiment of the invention.
- the "in line” pump according to the prior art (Fig. 1) comprises a high pressure body (9), a high pressure chamber (2) and a solid piston (8).
- the body and the piston have a filler joint (7) which must be submitted to the high pressure of the chamber (2).
- the fluid end comprises an inlet valve (1) in form of a ring assembled on the return spring (5), at the chamber end which is nearest the piston, and an outlet valve (3) also assembled on a return spring (4).
- the outlet valve is placed at the other end of the chamber (2) and can tightly close this end.
- the inlet pipes (6) When the piston displaces in the direction (A) of the inlet, the fluid is drawed by suction in a known manner by the inlet pipes (6). These pipes comprise a tore for symmetrically distributing the fluid.
- the valve (1) is pushed back and does not oppose the fluid inlet.
- the chamber (2) When the piston arrives on the thrust, the chamber (2) is then filled with the fluid, which is retained by the valve (3) pushed on its seat (10) by the spring (4).
- the joint (7) may not resist, or in badly manner, to the high pressure, which is a serious problem.
- the fluid circulation at the inlet in the pipes (6) is as a high abrasion and a risk of mechanical rupture especially at the zone (12) occur.
- the piston is itself modified and co-operates with a "in line" fluid end (Fig. 2).
- the equipment according to the invention comprises a high pressure fluid end body (21), a low pressure body (22) delimiting with the piston (16) a low pressure chamber (24), a fluid inlet pipe (26) and a discharge pipe (20).
- the high pressure body (21) delimites with the piston (16) a high pressure chamber (13).
- the piston (16) is partially hollow at its extension (17) placed in front of the discharge pipe (20) (free end of the piston).
- the said extension (17) determines in the body of the piston a high pressure chamber (19) which, to the rear, opens with an opening (or several) in the low pressure chamber (24), and, to the head (i.e. to the discharge pipe) comprises an inlet valve (15).
- the inlet valve (26) opens in the low pressure chamber (24) and the discharge pipe (20) has an outlet valve (14).
- a high pressure joint (23) makes the area between the high pressure chamber (13) and the low pressure chamber (24) around the piston tight.
- a low pressure joint (25) makes the low pressure chamber (24) tight.
- a known phenomenon implies a depression in the high pressure chamber (13).
- the valve (15) becomes opened, the valve (14) becomes closed, and the fluid circulates from the low pressure chamber (24) to the chamber (19) through the opening or port (18) and, finally, to the chamber (13).
- valve (15) When the piston pushes back in the direction (D), the valve (15) becomes closed, the fluid is compressed in the chamber (13) by the piston formed by the extension (17) filled with the fluid and closed by the valve (15), the valve (14) becomes opened and the fluid is ejected through the discharge pipe (20).
- the present invention provides several advantages, all are very important and even decisive.
- the dead volume may be lowered up to a very low volume, substantially equal to zero. This obviously has a positive effect on the volumetric efficiency of the high pressure pump.
- the pipe (26)/chamber (24)/chamber (19)/chamber (13)/discharge (20) fluid circulation is substantially ideal from the point of view of the fluid hydrodynamic. Especially, the fluid has not to radically change its flow direction. This will obviously decrease the cavitation which especially occurs with viscosified fluids, and with high flow rates, as well as the abrasion process.
- one or several pipes (26) may exist, including pipes with an annulus injection or a multi-point injection, as well as one or several openings (18) having an appropriate form.
- the applications relate to especially all the high pressure pumps in all industries.
