- F04C2240/601—Shaft flexion
Definitions
- the flex shaft can be made of a polyetheretherketone (PEEK), polyethylene (PE) or the like, for example.
- the flexible shaft can also be made of a steel cable, in particular a steel cable that is coated with plastic.
- the sealing element can be deformed particularly easily, as a result of which the radial movement of the flexible shaft in the drive shaft is not impeded.
- “bellows-shaped” means in particular that the sealing element is folded or has at least one fold.
- the rotor unit can also be used several times.
- the rotor assembly is disposable, it is made of a plastic material.
- the rotor unit can preferably be sterilized.
- the rotor unit can be used in biotechnology, for example.
- the progressing cavity pump 1 combines many positive properties of other pump systems. Like the centrifugal pump, the progressing cavity pump 1 has no suction and pressure valves. Like the piston pump, the progressive cavity pump 1 has excellent self-priming performance. Like the diaphragm or peristaltic pump, the eccentric screw pump 1 can convey any type of inhomogeneous and abrasive media M, which can also contain solids and fibrous materials.
- a gap 42 running completely around the flex shaft 31 is provided between the flex shaft 31 and the drive shaft 28 .
- the gap 42 can be an air gap.
- the gap 42 as in FIG 3 shown, also be filled with a sealant 43.
- the sealing compound 43 is elastically deformable, so that it does not impede the radial movement of the flex shaft 31 in the gap 42 or only insignificantly.
- a material with a low Shore hardness can be used for the sealing compound 43 .
- sealing compound 43 can be a silicone, in particular a two-component silicone, a silicone that cures at room temperature or RTV silicone (Engl .: Room-Temperature-Vulcanizing Silicone), a silicone that cures at high temperatures, a thermoplastic elastomer (TPE), in particular a thermoplastic Polyurethane (TPU), a thermoplastic vulcanizate (TPV), a fluorovinyl methyl silicone rubber (FVMQ) or the like.
- TPE thermoplastic elastomer
- TPU thermoplastic Polyurethane
- TPV thermoplastic vulcanizate
- FVMQ fluorovinyl methyl silicone rubber
- the sealing compound 43 can also be foamed, for example.
- the sealing compound 43 can have an open-pore or a closed-pore structure.
- the sealing compound 43 can be foam rubber-like.
- thermoplastic hoses can be welded together in a sterile manner or existing connections can be severed and the hose ends can be welded.
- Special rapid transfer systems have been developed for connection through a wall.
- hybrid processes in which single-use systems are combined with conventional stainless steel and glass systems.
- closed systems in which the one-way systems are linked together in the order of the process steps, and station systems, in which the intermediate products are transported to the next process step using mobile containers.
