Sourcing Industrial Equipment

Air cannons are the go-to solution for anyone who wants to eliminate blockages and build-up of deposits from vessels such as silos, hoppers and bins. The blockages often result from strong, cohesive forces between the particles moving through your vessels. With an air cannon fitted outside the powder-laden vessel, you can release a blast of compressed air into the clogged vessel. The compressed air flows into the vessel via a rapid exhaust valve capable of operating and different voltage ratings. Subsequently, the equipment receives immense pressure that forces the particles to break their cohesive forces and move through the vessel. The following piece focuses on the design elements you should consider when choosing air cannons for your commercial applications:

Robust Air Sweep Mechanism

The air sweep mechanism is the heartbeat of your air cannon. The best ones come with a spring-loaded piston rod and a valve that allows the immediate release of compressed air when commanded. Ideally, the essence of the spring mechanism is to reinforce the piston and give it the strength it needs to push compressed air. It also keeps the piston from snapping when it encounters resistance when pushing compressed air into the vessel. The spring absorbs the shock resulting from such resistance.

Double Piston Combination

You can also make the most of your air cannon by going for a double piston combination fitting loosely in the cannon's cylinders. A no-tight tolerance fitting creates pressure behind the two pistons and pushes them against a valve seat to create a reliable seal. When you use this combination, there is no need for additional O-rings to keep the hydraulic fluid within the piston chambers, reducing the cost of assembly and installation. Moreover, the setup and absence of O-rings eliminate the risk of clogging, jamming or sticking during operation. O-rings also have operational limitations because they can dry out and crack, losing the desired sealing capability.

Stainless Steel Tank

When using air cannons, you need to be wary of the working environment. Lots of moisture, harsh chemicals and exposure to other elements can degrade the air cannon materials. Specifically, it helps to pay attention to the material used to make the high-pressure tank because it houses the most significant operational hazard. Go for reinforced stainless steel tanks to guarantee against physical damage resulting from exposure to harmful elements. Galvanised aluminium tanks can also suffice for light-duty blasting applications. The galvanic coating excels at corrosion resistance.
