Definitions

the invention relates to a high-pressure plunger pump, preferably for working pressures above 2,000 bar, with a pump head, a housing, a drivable plunger, a pressure and suction valve arranged coaxially to the longitudinal axis of the plunger, and an inner body having the working space of the pump, which is provided by a suction chamber containing liquid to be sucked is enclosed.
a high-pressure plunger pump of this type is known (EP 0 551 590), in which the inner body having the working space of the pump is designed as a floating sleeve on the plunger. At the end facing the suction valve, the interior of the sleeve tapers, so that during the pressure stroke the sleeve is pressed against an insert body by the conveying medium.
This insert body is formed in two parts, the part facing the plunger having the seat of the suction valve and the part facing the pump head having the seat of the pressure valve.
the invention has for its object a high pressure plunger pump, preferably for working pressures above 2,000 bar to design that it is composed of a few, easy-to-manufacture components that ensure a good seal between the work and the suction space.
the plunger is slidably mounted in a longitudinal bore of the inner body and in an insertion sleeve received by an extension of the longitudinal bore, the insertion sleeve is provided with an annular flange at the end facing the plunger drive and in the transition area from the annular flange to the sleeve body a seal is arranged between the working space and the suction space.
the expansion is eliminated by the elasticity under the operating pressure, since the working pressure from outside and inside prevails up to the seal near the ring flange. Since the sealing gap is included in the calculation of the leakage rate in the third power, the leakage rate is significantly reduced in the embodiment according to the invention.
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.
a valve seat ring with valve seat surfaces for the pressure valve and for the suction valve is provided in the space between the pump head and the inner body containing the working space.
a suction valve body equipped with a central overflow bore and an associated spring are arranged in a cylindrical recess of the inner body adjoining the valve seat ring.
the pump head is connected to the inner body.
this connection between the pump head and the inner body is carried out by screws which start from the outer boundary surface of the pump head and are screwed with their threaded shank into threaded bores in the inner body of the pump.
valve seat ring which has both the seat surface for the suction valve and the seat surface for the pressure valve.
the harmful space is kept particularly small in order to offer the compressibility of the medium as little chance as possible of worsening the 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 is enclosed by the suction chamber 4 of the pump and is connected to the pump head 2 by screws 5. These screws 5 extend from the outer surface 6 of the pump head over the entire height of the pump head and are screwed with their threaded shaft 7 into threaded bores 8 of the inner body 3.
valve seat ring 9 is provided, which is positively connected to both the pump head 2 and the inner body 3.
the valve seat ring 9 is provided with a sleeve-shaped insert 10, which forms the seat for the pressure valve 11.
the seat surface is 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 arranged in a stepped bore in the inner body 3.
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 slidably mounted in a longitudinal bore 18 of the inner body 3 and in an insertion sleeve 19.
the insertion sleeve 19 is provided with an annular flange 20 and is received by an extension 21 of the longitudinal bore 18.
the ring flange 20 of the insertion sleeve 19 is arranged in a recess of the inner body 3 corresponding to the contour of the ring flange.
a triple step of a recess is provided at the end facing the valve seat ring 9.
One step is provided for the spring 14, another step for the suction valve body 12 and one step for a projection 26 of the valve seat ring 9.
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 engage in corresponding recesses in the pump head 2.
