Definitions

  • the invention relates to a radial pump with a housing in which a driven by a shaft impeller is rotatably mounted with a on the suction side of the impeller in the housing axially in the direction of the impeller between two end positions slidably mounted cover ring, wherein by moving the cover ring from a through a housing stop limited first end position between a wheel and housing formed gap is releasable, wherein the cover ring is automatically adjustable depending on the pressure difference between the pressure and suction side of the impeller, wherein the cover ring in at least one defined position, preferably at least in the first end position, by a positioning element preferably formed by at least one latching device can be positioned.
  • cooling water pumps of internal combustion engines are designed so that even at relatively low engine speeds high coolant flows can be provided.
  • the delivered volume flow, but also the power consumption of the pump is much higher than necessary, which adversely affects fuel consumption. Apart from that, it can come in the high speed range to cavitation phenomena.
  • a cooling water pump for an internal combustion engine is known.
  • a displaceable in the axial direction cover ring is inserted.
  • the cover ring is adjustable by an actuator having a pressure cell depending on parameters of the internal combustion engine. Due to the displacement of the cover ring, the width of a gap between the ring and the impeller of the water pump is variable, so that the cooling water flow rate is variable. This makes it possible to shorten the warm-up phase of the internal combustion engine and to reduce the amount of harmful exhaust gas components.
  • US Pat. No. 2,786,420 A also describes a radial pump in which a cover ring can be adjusted by means of a pressure cell as a function of the pressure difference between the pressure and suction side.
  • FR 2 681 906 A1 describes a radial pump for coolant for internal combustion engines, wherein a housing wall adjoining the main pumping chamber of the pump can be displaced so that an impeller gap between the housing wall and the impeller and thus the delivery flow of the pump can be adapted to one or more engine parameters.
  • the object of the invention is to reduce as much as possible the flow rate and the power consumption at high speeds while ensuring a stable operation.
  • the positioning element has at least one approximately radially with respect to the impeller axis spring-loaded pressure body, which cooperates in the defined position with a reciprocally shaped locking element and is slidably disposed along a guide surface and that the pressure body is formed by a spring ring.
  • the latching element is preferably formed by a recess in the guide surface.
  • the guide surface is formed by a suction-side inner surface of the housing and the pressure body is arranged in the jacket region of the cover ring.
  • the guide surface is formed by the jacket region of the cover ring and that the pressure body is arranged in the region of an inner surface of the housing on the suction chamber side.
  • the guide surface is inclined with respect to the wheel axis by an angle less than about 20 °, preferably less than about 10 °.
  • a pressure spring acting on the pressure body can be arranged in a radial bore of the cover ring or of the housing.
  • the pressure body has a convex surface.
  • At least one short-circuit channel is arranged in the region of the cover ring.
  • the short-circuit channel can be formed by at least one formation in the housing and / or in the cover ring.
  • the short-circuit channel is opened by the cover ring and is designed so that the flow cross-section increases with the deflection of the cover ring. This ensures that in the upper speed range relatively large flow rates are diverted, causing the Power consumption of the radial pump can be significantly reduced in this operating range.
  • the gap between the impeller and housing is independently adapted to the current impeller speed, thereby consuming actuators can be omitted.
  • the cover ring formed at least by a restoring element restoring force in the direction of the first end position.
  • the restoring element is formed by a resilient biasing means, preferably a return spring, which acts in the direction of the impeller axis on the cover ring.
  • the radial pump 1 has a housing 2, in which a shaft 3 for driving an impeller 4 by means of a bearing 5 is rotatably mounted.
  • the suction side of the radial pump 1 is denoted by reference numeral 6, the pressure side by reference numeral 7.
  • the impeller 4 around the housing 2 forms a spiral channel 8.
  • a cover ring 9 is slidably disposed in the housing 2 in the direction of the impeller axis 10 between a first and a second end position. In the first end position shown in FIG. 1, a gap 11 formed between impeller 4 and housing 2 is covered by cover ring 9, so that leakage flows between pressure side 7 and suction side 6 are prevented.
  • the cover ring 9 is moved by at least one return element 12 in the first end position or held in this.
  • the return element 12 shown in FIG. 2 consists of a restoring spring 14 formed by a spring plate, which acts in the axial direction on the cover ring 9.
  • the positioning element 13 shown in Fig. 3 is disposed in the jacket portion 15 of the cover ring 9 and has a spring-loaded by a compression spring 16 pressure body 17, wherein the compression spring 16 is disposed in a radial bore 18 in the jacket portion 15 of the cover ring 9.
  • the pressure body 17 may be formed, for example, by a ball or hemisphere 17a.
  • the pressure body 17 rests on a guide surface 19 formed by a suction-side inner surface 2a of the housing 2 and slides along the axial deflection of the cover ring along this, wherein the pressure body 17 engages in the first end position in a formed by a recess 20 form element and thus the position stabilized the cover ring 9.
  • the guide surface 19 is slightly inclined relative to the impeller axis 10, wherein the angle ⁇ between the guide surface 19 and the impeller axis 10 is less than about 10 °.
  • the cover ring 9 rests against a stop 21 formed by the housing 2.
  • the cover ring 9 is moved in response to the pressure difference between the pressure p 2 of the pressure side 7 and the pressure p 1 of the suction side 6 from the first end position determining a rest position in the second end position.
  • the cover ring 9 Up to a predefined speed of the impeller 4, which is associated with a certain flow, the cover ring 9 is positioned in the first end position shown in Fig. 1 with a very small gap 11 with respect to the impeller 4, so that an optimum efficiency is achieved.
  • This position is defined on the one hand by the stop 21 in the housing, on the other hand by the return element 12 and the positioning element 13.
  • the return element 12 and the positioning element 13 can also be used in combination in order to ensure a demand-oriented control characteristic.
  • the reset and positioning elements 12, 13 are designed so that at a certain pressure difference p 2 - p 1, an axial displacement of the cover ring 9 takes place away from the impeller 4. Depending on the design of the reset and positioning elements 12, 13, this axial adjustment can take place continuously or abruptly above a certain speed.
  • the increasing axial gap 11 between the impeller 4 and cover ring 9 causes a reduction in the flow rate and thereby also a reduction in power consumption at high speeds. Furthermore, the cavitation occurring in the high speed range is prevented.
  • the housing 2 has at least one short-circuit channel 23, which enables the flow connection according to the arrow S between the pressure side 7 and suction side 6 of the radial pump 1 in the deflection of the cover ring 9 shown in FIG.
  • the short-circuit channel 23 is opened by an edge 24 of the cover ring 9 and is designed so that the flow cross-section increases with the size of the deflection of the cover ring 9. As a result, relatively large quantities of the pumped medium are deactivated at high speeds.
