Estimating the term…
A stator for a pump, in particular for a rotary piston pump or an eccentric screw pump, having a base body, wherein the base body surrounds a pumping area for a rotor arrangement of the pump, includes a support body and a running body, and the running body configures a running surface for at least partial contact with the rotor arrangement of the pump, wherein the support body and the running body includes a common material and wherein a material density of the material of the support body and a material density of the material of the running body are configured differently from one another, so that a different elasticity and/or a different hardness of the material is achieved in the support body and in the running body by means of the differently configured material densities. Furthermore, the invention relates to a method for producing such a stator.
A stator for a pump, in particular for a rotary piston pump or an eccentric screw pump, having a base body, wherein the base body surrounds a pumping area for a rotor arrangement, the pump, comprising a support body and a running body, said running body configures a running surface for at least partial contact with the rotor arrangement of the pump, said support body and the running body include a common material where a material density of the material of the support body and a material density of the material of the running body are configured differently from one another, so that a different elasticity and/or a different hardness of the material in the support body and in the running body is achieved by means of the differently configured material densities.
A method for producing a stator for a pump, in particular for a rotary piston pump or an eccentric screw pump, having a base body, wherein the base body surrounds a pumping area for a rotor arrangement of the pump, the pump having a support body and a running body, and the running body configures a running surface for at least partial contact with the rotor arrangement of the pump, the support body and the running body includes a common material and in that a material density of the material of the support body and a material density of the material of the running body are configured differently from one another, so that a different elasticity and/or a different hardness of the material in the support body and in the running body is achieved by means of the differently configured material densities., wherein the stator comprises a base body having a support body and a running body, the base body surrounds a pumping area for a rotor of the pump, and the running body configures a running surface for at least partial contact with the rotor of the pump, wherein the base body includes material densities differing from one another, wherein the method comprises the following steps:
A stator for a pump, in particular for a rotary piston pump or an eccentric screw pump, having a base body, wherein the base body surrounds a pumping area for a rotor arrangement of the pump, a support body and a running body, and the running body configures a running surface for at least partial contact with the rotor arrangement of the pump, the support body and the running body includes a common material and in that a material density of the material of the support body and a material density of the material of the running body are configured differently from one another, so that a different elasticity and/or a different hardness of the material in the support body and in the running body is achieved by means of the differently configured material densities, which is produced by a material-forming primary shaping method, in particular an additive method and/or a sintering method, wherein the treatment takes place in a common manufacturing process by an adjustment of respective manufacturing parameters.
