Document Status Indicators The Green document status indicator indicates that the document is: Establishes guarantees, tests, analysis, measurement of thrust and measurement of mixer electric power uptake. A mixer can be withdrawn from the tank for repair and maintenance work at any time.

Mixers are blending devices used in process engineering. They are driven by three-phase asynchronous motors which are safe to run dry.

The positioning of the mixer including installation accessories is performed in isl a way that it is correctly orientated before being lowered into its working position in a mounting bracket.

Appropriately designed installation equipment ensures that the forces developing during operation are transmitted to the tank floor. Mixers consist of the following components: Main hydraulic tasks Introducing and mixing various gases, liquids or solid substances 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.

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

Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. Mixers are sealed to prevent ingress of water and come either in a close-coupled design or with gear unit. The Amber document status indicator indicates that some caution is needed when using this document – it is either: Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.

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. The applications and wide range of hydraulic tasks to be fulfilled by mixers entail different requirements for these machines.

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 216330. Mechanical seals are used for sealing on both the product side and the drive end.

Other mixer types are driven by dry-installed standard motors and medium-exposed shafts. By continuing to browse the web site you consent to the use of cookies. Search A-Z Suche nach.

Mixer Mixers are blending devices used in process engineering. Again there may be more recent versions of the document. If 216630, several mixers should be installed in a tank. Specific propeller orientation helps create a circumferential flow. Mixers are used for homogenising, emulsifying, dispersing, suspending and flow generation.
