how does a tubular drag chain conveyor work?
364101
Tubular Drag conveyors are used to convey a wide range of powders and bulk solids in the food, chemical, pharmaceutical, mining and wastewater treatment industries. They are an excellent choice for dependable 24/7 operations which require low segregation and/or degradation; complete enclosure for dust control; the handling of high moisture content materials, difficult to handle abrasive materials or ones which may tend to pack / smear; and in situations which may require multiple inlets and/or outlets. They are extremely flexible in plant layouts and integrate well with existing equipment. Bulk materials are conveyed between the sealed-pin chain flights, at virtually any angle, for distances of up to 85 feet vertically, and more than 200 feet horizontally, depending on material bulk densities and required capacity. Flights can be specified in a choice of several materials (depending upon the application) and are easily replaceable. Models ranges in size from 3-inch diameter up to 12-inch with pipe construction of schedule 10, 40, 80, or Abrasion Resistant Lining. Capacities can reach up to 60 cubic feet per minute, with a maximum conveyor speed of 185 feet per minute, for straight run configurations.

It's a very clever device actually.  You have a circular armature that spins in the middle sorrounded by circular coils.  Both of these parts have conducting coils of wire in them. So you have a series of electromagnets shaped around each other.  \n\nThere are also switches that move the current around the particular sections.  When you plug the motor in, the magnetic field can be manipulated so that it moves around in a circular path.  The magnets in the armature are drawn to it and move toward it.  But as soon as it gets close, it is switched off and the next one along the circle is turned on.  Again, pretty tricky to make, but we've figured it out - great device.

You mean the part that gives the traction?  It is essentially a large chain like device made of steel plates linked together kinda like a bicycle chain.  The wheels have teeth on them that drive and guide the track.  Often the plates of the track will have a section of hard rubber tread attached to them also since a tank is made to travel and not push like a bull dozer which have the steel treads that bite in deep.  A tank travels much faster and often on roads and the rubber prevents excess damage to the road and allows higher speed and better handling.  Google up some images for "Tank track"

That is one VERY GOOD question! Excellent! Now....can I answer it....lol. Part of the action of a siphon is the fact that the fluid has weight and as such helps create a negative pressure behind it that helps pull the rest of the fluid with it. That's why you have to have the exit below the surface of the fluid you're siphoning.\n\nNow...if you try this with a bucket the water will flow down the tube, or hose, but then it has to flow back up again to get back into the bucket. That will be an impedence to the flow. Gravity will not be enough to help keep the flow alive, so it will not work.\n\nThe other answer cites a perpetual motion machine....and correctly so. There is no such thing as perpetual motion defies a law in an area of physics called thermodynamics.

It stamps and moves the piece automatically, usually to another machine tool which does more work on the piece. Sometimes the transfer press stamps the piece a few times itself as it moves from die to die within.

conveyors needs an electrical drive to operate.\ntell me wht function u exactly need with ur conveyor ie forward run and reverse run and anything more.\notherwise mail me at addudiamond@yahoo.com

It is usually self-hoisting. There is motor and gear assenbly that lifts the crane within the tube (usually a future elevator shaft) the is constructed around it. Then it is bolted down and goes back to work.

try this website.\n\nYou should give more info about what sort of mechanisms you are looking for.

a compound machine would involve multiple mechanical devices.  For example a pulley connected to a lever which is connected to a gear system would be a good example.  This would be used possible to mechanically lift a load.

If you think on the lines of the principle of using your bicycle to make the light work which is attached to the back wheel...then how about if you attach a paddle to the the dynamo place it in the house roof drain pipe. In theory when it rained the force of the water running down the drain pipe would generate enough energy to turn the dynamo.\nHence you have solved how to make current with a dynamo at home....brilliant!!!!!!

I can't say for certain, but I assume the length of the gaps does not increase.  The length of the tubes increase so that the time it takes to traverse the tube stays the same.  I think the only constraint on the gaps is how close the tubes can be to each other.  You'd want it to be as small as possible to get as much accelleration as possible.

Actually, it is a third class lever. The spring force is acting very close (radius of the wire) to the fulcrum, and the load is a significant fraction of an inch away.

It's the oil flow that causes the operation of the hydraulic cylinder.  The oil, under pressure, causes the piston in the cylinder to move in or out.  No oil flow, no motion.  \n \nPressure gives power.  100 PSI of oil pressure onto a 5 sq. in. piston results in 500 pounds of force from the rod.  \n \nVolume of flow gives speed of motion.  1 cubic inch per second of oil will produce a certain movement by filling the cylinder so fast.  10 cubic inch's per second will produce a motion ten times as fast.

You have a bevel gear on the end of the drive shaft (the input shaft to the differential). This gear right-angle drives a large "planetary" or ring gear that rotates about the axle but is not attached to it directly, but is attached via a yoke that carries two intermediate bevel gears, and these gears mesh with the gears that drive the two wheels. (You really need to look at the ref.) When the two wheels want to rotate at the same speed, the two bevel gears do not need to rotate and the transmission acts like a simple nondifferential mechanism. However any differential motion of the wheels is accommodated by rotation of the intermediate gears.\nP.S. For some reason I had to go to another page (at the ref. website) and then back to get the animations to work right.

Use the box of baking soda as a weight to provide torque to propel the vehicle and to wind the rubber bands. Once the box hits the ground, the hook can fall off and the rubber bands will unwind and propel the vehicle back the 1m.\n\nYou are using the box of baking soda as potential energy converted to kinetic energy to wind the bands and propel the vehicle.

Yeah, a friend had one of those. Um... let me see how to explain it...\nWell, the staples load from the rear. At the base of the big handle, there should be a tab or black plastic thingie there (yeah, I know...so technical). Just pull it straight back. Directly back from the handle all the way out and put some staples in. Then, try to get the parts back on track and let it go. It has a spring that pulls everything forward.\nIf that doesn't work, I must be remembering wrong.
