Definitions

  • the invention relates to an eccentric screw pump with a screw-shaped Rotor that rotates in a coiled stator chamber and a drive shaft that Connects rotor with a drive.
  • the object of the invention is therefore to reduce the assembly time when replacing rotor-stator or joint parts, especially at the customer.
  • stator is in many cases between two side flanges by means of a Tie rod assembly is clamped, it can be advantageous according to the invention if divided the pump housing and its parts using a quick release device or quick coupling are connected to each other.
  • the complete stator and part of the pump housing are designed together with the drive shaft, the joints or the flexible shaft and the Seal removed and replaced.
  • a gear e.g. parallel shaft gear
  • the gearbox has a hollow shaft.
  • the bearing in the pump housing sits in this hollow shaft sealed drive shaft for the rotor.
  • the drive shaft is through a screw axially clamped with the hollow shaft.
  • the torque is transmitted through a Shaft-hub connection e.g. a key ..
  • FIG. 1 An embodiment of the invention is shown in FIG. 1.
  • FIG. 1 shows an eccentric screw pump 10 of the Moineau type with a drive 12 and a gear 14, which in via a hollow shaft with a drive shaft 16 Connection is established.
  • the drive shaft 16 is provided with a seal 18 which prevents the ingress of Product in the area of storage 20 prevented.
  • the flexurally elastic shaft 22 and the drive shaft 16 are by a screw / shrink or adhesive connection fixed in rotation with each other.
  • the pump housing 26 has a Inlet 28 through which the product is sucked into the eccentric screw pump 10 becomes. By loosening the screw 30 and opening the quick release device 32 the entire stator 38 can be simultaneously with the end piece 34 with the rotor 36, the flexible shaft 22, the drive shaft 16 and the seal 18 as one Pull unit from pump housing 26 and drive 12 and against a new one Replace exchange unit.
