Document Status Indicators The Green document status indicator indicates that the document is: The propellers are designed with fibre-repellent, self-cleaning blades with backward curved incidence edges and are made of grey cast iron, stainless steel or a synthetic material depending on the fluid to be handled. Specific propeller orientation helps create a circumferential flow.

Other mixer 26130 are driven by dry-installed standard motors and medium-exposed shafts. Mixers are used for homogenising, emulsifying, dispersing, suspending and flow generation. Establishes guarantees, tests, analysis, measurement of thrust and measurement of oso electric power uptake.

The Amber document status indicator indicates that some caution is needed when using this document – it is either: Again there may be more recent versions of the document. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. The applications and wide range of hydraulic tasks to be fulfilled by mixers entail different requirements for these machines.

ISO 21630:2007

Mixers are installed via a guide bracket fitted to the mixer; it allows the submersible mixer to be lowered into the tank along a guide rail. Mixers are blending devices used in process engineering. The positioning of the mixer including installation accessories is performed in such a way that it is correctly orientated before being lowered into its working position in a mounting bracket.

Mixers are sealed to prevent ingress of water and come either in a close-coupled design or with gear unit.

They are driven by three-phase asynchronous motors which are safe to iwo dry. Appropriately designed installation equipment ensures that the forces developing during operation 2160 transmitted to the tank floor.

The bearings used are maintenance-free rolling element bearings. Mixers are designed for stationary installation on the tank floor or tank wall, or for pedestal mounting.

A mixer can be withdrawn from the tank for repair and maintenance work at any time. Search A-Z Suche nach. Mixers consist of the following components: Mechanical seals are used for sealing on both the product side and the drive end.

Main hydraulic tasks Introducing and mixing various gases, liquids or solid 26130 into a fluid Preventing conglomeration of sludge flakes Circulating phase mixtures Preventing sedimentation in the case of insufficient fluid flow velocity in the tank Aligning the mixer to break up floating sludge layers The applications and wide range of hydraulic tasks to be fulfilled by mixers entail different requirements for these machines.

If required, several mixers should be installed in a tank.
