The selection of agitators for a particular application depends on various factors like:
- The phase to be mixed (single-phase or multiphase).
- The viscosity of the bulk.
- Exact function required (blending, dissolving, dispersion, heat exchange, chemical reaction, crystallization, emulsification, suspension, etc).
What is agitator used for?
An Agitator is a machine used in a tank for mixing various process media together. Media include all liquid types, gases & solids (such as salts, powders, granules etc). In summary, it works by rotating an impeller to impart energy to the media which interact and mix.
What is mechanical agitator?
Mechanical agitation may be used to suspend particles in a liquid in order to promote mass transfer or a chemical reaction. The liquids involved in such applications are usually of low viscosity, and the particles will settle out when agitation ceases.
What is hydrofoil agitator?
hydrofoil impeller is a type of axial flow impellers used in a wide range of applications. This mixing blade is suitable for the stirring, dissociation, solid suspension, heat transfer, reaction and crystallization of low viscosity liquid.
How do I choose an agitator type? – Related Questions
How many types of agitators are there?
The types of agitators are paddle agitators, anchor agitators, helical ribbon agitators, propeller agitators, turbine agitators, agitators with screw impellers, retreat curve impellers, hydrofoil impellers, dispersion blade impellers, and coil impellers.
Why did the Navy stop using hydrofoils?
The ships were retired because they were not judged cost effective for their mission in a Navy with primarily offensive missions rather than coastal patrol.
What is the purpose of a hydrofoil?
Hydrofoils are the plates that bolt on your outboard cavitation plate, which increase the surface area of the plate. They work by lifting the boat out of the water as the boat gathers speed, creating less drag. This helps to increase acceleration, giving you more power and reduced strain on the engine.
Does my outboard need a hydrofoil?
Installing a hydrofoil allows your boat to get up out of the hole faster and accelerate more efficiently when up on plane. Even at low speeds, you can benefit from better performance because the hydrofoil keeps you up on plane.
What is a hydrofoil and how does it work?
A hydrofoil works on the principle of Newton’s third law — “For every action in nature, there is an equal and opposite reaction.” The foils, or wings, start beneath the water. As the surfboard begins to gain speed, the wings push the water down, creating an upward force in reaction to downward pressure.
Does hydrofoil help with steering?
Fitting an outboard or inboard/outboard hydrofoil on your motor could help you achieve crisper steering and more power over what your boat does.
Is riding a hydrofoil hard?
As effortless as experienced foil surfers make it look as they fly along the coast, it’s actually a lot harder than it looks. The specifics of the balance involved make foil surfing more challenging than traditional surfing while you’re getting started.
Do hydrofoils work in rough water?
The evidence is that rough water has little effect on the overall performance of fully-submerged, automatically con- trolled hydrofoils, and that the ability of large hydrofoils to conduct mission operations in the open ocean is not significantly affected.
Do hydrofoils slow you down?
Hydrofoils work to help a boat reduce drag and increase speed. Because water provides resistance to a ship trying to move through it, the resulting pushback can make a vessel slow down, even at peak operation.
What would cause a boat not to plane?
Fortunately, planing, which enables a boat to rise partially out of the water and skim along at higher speeds because of reduced hull friction, can be improved. There are many reasons for a boat not planing efficiently. The most common are overloading and failure to distribute weight properly.
Are sharks attracted to hydrofoils?
Sharks may be attracted by the vibrations of the foil. Sharks may be curious when they see/hear a foil approach, and come close for inspection. Hydrofoils are quieter than regular kiteboards or windsurf boards, and the fish/sharks do not realize until the last second that there is something close to them.
How long does a hydrofoil last?
Models like the Epic Electric Hydrofoil lasts around 60 minutes when used to fly. Others, however, may have a flying time of 70-90 minutes. Most e-foil boards also operate on an average speed of 20 km/hour. Depending on battery life, some have a top speed of up to 50 km/hour.
Why are foil boards so expensive?
In addition to the lack of production volume, foil designs change quickly, which explains its high price. Each new design needs new molds, which must be researched and developed, tested, prototyped. Supply and demand. When the demand is high, the price is high – this law applies to eFoil boards as well.
