摘要： The invention relates to an eccentric screw pump comprising a stator-rotor system having a rotor with a rotor screw and a stator with an inner thread. The stator comprises a support element and an elastomer part, wherein the support element completely surrounds some sections of the elastomer part. According to the invention, the stator-rotor system has an adjustment mechanism for adjusting the stator. The adjustment mechanism is coupled via a controller to at least one sensor for determining actual operating parameters of the stator-rotor system and/or of the eccentric screw pump, wherein an actuation of the adjustment mechanism can be carried out by the controller, taking into consideration the actual operating parameters determined by means of at least one sensor. The invention also relates to a method for adapting the operating state of an eccentric screw pump.

摘要： Provided is a uniaxial eccentric screw pump enabling a stator to be easily separated into an outer cylinder and a lining member, and being capable of solving problems such as a positional shift and deformation of the lining member, and an occurrence of uneven wear and an unstable discharge amount associated with the positional shift and deformation. A stator (20) includes: a liner portion (22) having a cylindrical shape and being integrally formed so as to have an inner peripheral surface of an internal thread type; and an outer cylinder portion (24). The liner portion (22) includes, at both end portions thereof, flange portions (26, 26) protruding radially outward, and an outer cylinder mounting portion (28) is provided between the flange portions (26, 26). The outer cylinder portion (24) is mounted in a non-bonded state on the outer cylinder mounting portion (28), and both end portions of the outer cylinder portion (24) abut on the flange portions (26, 26), respectively.

摘要： The invention relates to a clamping device for fixing a drive shaft of a delivery pump within a rising pipe of a borehole for the delivery of a delivered fluid. The clamping device comprises a housing having a first passage bore, through which the drive shaft of the delivery pump passes. The clamping device also comprises at least one second lateral passage bore, which hits the first passage bore orthogonally, wherein in the second passage bore a mechanically acting clamping means is accommodated and/or guided, by means of which the drive shaft of the delivery pump can be axially and/or radially fixed in the housing of the clamping device. The invention further relates to a method for spatially fixing a drive shaft of a delivery pump in a rising pipe associated with a borehole in a stationary manner. In said method, at least one clamping device is arranged between the borehole and a drive head associated with the drive shaft. In a first operating position of the clamping device, the delivered fluid is conducted through the clamping device. In a second operating position of the clamping device, a first compressive or clamping force is applied to the drive shaft by means of the clamping device, which first compressive or clamping force prevents the drive shaft from twisting radially. Alternatively or additionally, a second compressive or clamping force can be applied to the drive shaft by means of the clamping device, which second compressive or clamping force prevents the drive shaft from slipping axially.

摘要： Disclosed is a screw pump for delivering a fluid medium. The screw pump comprises a pump housing for the medium to be delivered, said housing having an inlet and an outlet. Said screw pump comprises at least two screws. Said at least two screws consist respectively of a shaft having at least two shaft sections and a profiled section arranged therebetween, said profiled sections of the at least two screws engaging at least partially with each other. The at least two screws are arranged so that they can rotate at least partially in the pump housing. The first screw is designed as a drive screw. Said drive screw is associated with a direct first drive. According to the invention, a second drive is associated with at least one second screw.

摘要： The invention relates to an adaptive eccentric screw pump (2), which enables, if necessary, an increase of the output, the pressure and/or the simultaneous output of more than one output medium, and wherein the eccentric screw pump (2) has comparably low energy consumption and the production and maintenance expenditure thereof is kept low. For this purpose, according to the invention, the eccentric screw pump (2) is equipped with a modular output system, comprising at least two output modules (4, 6, 38, 40) comprising in each case one rotor (10) and one stator (8), wherein the output modules (4, 6, 38, 40) are coupled to one another and merely one actuation unit (14) is associated with the output system, and wherein the output system for an output medium has more than one inlet and/or outlet (18, 24) or at least one modular perfusion housing (12).
