Definitions
- the invention relates to a high-pressure plunger pump, preferably for working pressures above 2,000 bar according to the preamble of claim 1.
- a high-pressure plunger pump of this type is known (EP 0 551 590 A), in which the the working area of the pump having the inner body as floating on the plunger mounted sleeve is formed. Tapered at the end facing the suction valve the interior of the sleeve, so that during the pressure stroke the sleeve through the medium is pressed against an insert body.
- This insert body is in two parts formed, the part facing the plunger the seat of the suction valve and the part facing the pump head has the seat of the pressure valve.
- a plunger which is in a longitudinal bore of the inner body as well as in an insertion sleeve that receives the extension of the longitudinal bore is slidably mounted.
- the insertion sleeve is in the plunger facing Side provided with an annular flange, wherein a seal is provided, which in Transition area from the ring flange to the plug-in sleeve seals the work area.
- the invention is based on the object a high pressure plunger pump, preferably for working pressures above 2,000 bar to design that it consists of a few, easy to manufacture components, which ensure a good seal between the working and the suction area
- the expansion is caused by the elasticity under the operating pressure eliminated because the working pressure up to the seal near the ring flange rules from outside and inside. Because the sealing gap in the calculation of the leakage rate enters into the third power, the Leakage rate significantly reduced.
- the piston made of hard metal or ceramic shows hardly any signs of wear. From time to time only the insert sleeve has to be replaced.
- the high-pressure plunger pump is in the space between the pump head and the one containing the working space Inner body of a valve seat ring with valve seat surfaces for the pressure valve and provided for the suction valve.
- One equipped with a central overflow hole Suction valve body and an associated spring are in one on the valve seat ring adjacent, cylindrical recess of the inner body arranged.
- the Pump head is connected to the inner body.
- This connection between the Pump head and the inner body is in an advantageous embodiment Invention made by screws from the outer boundary surface the pump head and with its threaded shaft in threaded holes of the inner body of the pump are screwed in.
- the object of the invention is in the transition area from the housing to Pump head as insert body only a valve seat ring is present, which covers both the seat for the suction valve and the seat for the pressure valve.
- the harmful space is kept particularly low to reduce the compressibility of the medium to offer the lowest possible chances of worsening efficiency.
- the high-pressure plunger pump shown in the drawing has a housing 1 and a pump head 2 and is equipped with an inner body 3 which of the suction chamber 4 of the pump and enclosed by screws 5 with the pump head 2 is connected. These screws 5 extend from the outer surface 6 of the pump head over the entire height of the pump head and are with their Threaded shaft 7 screwed into threaded holes 8 of the inner body 3.
- a valve seat ring 9 is provided between the pump head 2 and the inner body 3, the form-fitting with both the pump head 2 and the inner body 3 connected is.
- the valve seat ring 9 is provided with a sleeve-shaped insert 10, which the seat forms for the pressure valve 11.
- valve seat ring 9 On the side of the valve seat ring 9 opposite the pressure valve is the seat surface provided for an annular suction valve body 12 which has a central overflow bore 13a.
- a spring 14 is assigned to the suction valve body 12.
- Both the suction valve body 12 and the spring 14 are in a stepped bore of the inner body 3 arranged.
- suction channels 15 extend to the seat 13 of the Suction valve. These suction channels run at an acute angle to the central longitudinal axis 16 of the valve seat ring or the high pressure plunger pump, in which the Pressure valve and the suction valve are arranged coaxially.
- the pump is equipped with a drivable plunger 17, which is in a longitudinal bore 18 of the inner body 3 and in an insert sleeve 19 is slidably mounted.
- the insertion sleeve 19 is provided with an annular flange 20 and is an extension 21 of the longitudinal bore 18 added.
- the ring flange 20 of the insertion sleeve 19 is in a recess corresponding to the contour of the ring flange Inner body 3 arranged.
- a projection 22 of one also projects into this recess Cover 23, which is connected by screws 24 to the inner body 3. This Projection 22 is supported on the ring flange 20.
- a seal 25 In the transition area between the ring flange 20 and the sleeve body of the insertion sleeve 19 is a seal 25 arranged, which seals the working space of the pump from the suction chamber 4.
- the pressure stroke of the plunger it builds up in the annular gap between the plunger and the sleeve body of the insertion sleeve 19 and in the annular gap between the sleeve body and the inner body 3, a pressure by which the elastic deformation of the sleeve body is completely or largely eliminated.
- valve seat 9 A positive connection between the valve seat 9 and the pump head 2 is achieved by a stepped projection 27 of the valve seat ring 9, which in corresponding Engage recesses in the pump head 2.
