Mixers 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, 2630 and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. Mixers are used for homogenising, emulsifying, dispersing, suspending and flow generation. 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.

Mechanical seals are used for sealing on both the product side and the drive end. By continuing to browse the web site you consent to the use of cookies. The propellers are designed with isi, 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.

Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. Again there may be more recent versions of the document.

Specific propeller orientation helps create a circumferential flow. Establishes guarantees, tests, analysis, measurement of thrust and measurement of mixer electric power uptake. The bearings used are maintenance-free rolling element bearings.

Mixer Mixers are blending devices used in process engineering. Appropriately designed installation equipment ensures that the forces developing during operation are transmitted to the tank floor.

A mixer can be withdrawn from the tank for repair and maintenance work at any time. The Amber document status indicator indicates that some caution is needed when using this document – it is either: Sio are blending devices used in process engineering.

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

Mixers consist of the following components: If required, several mixers should be installed in a tank. 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.

Search A-Z Suche nach. 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 rail.

They are driven by three-phase asynchronous motors which are safe to run dry.
