The application of conveyor belt fluid coupling

Fluid coupling is a used fluid transmission component. Motor drives coupling pump wheel rotation, pump impeller blade agitates intracavitary working liquid, under the centrifugal effect,pump wheel turns mechanical energy into liquid energy, then passes to the turbine blades, turbine passes the absorbent liquid energy to the machine.
Fluid coupling has the function of flexible transmission,slow down the impact and the isolation of torsional vibration, prolong the start-up time, reduce the starting current,make the motor light load start-up, solve the problem of heavy large inertia load start-up difficulties and protect the motor when overloads, energy and power saving effects are remarkable.
On the conveyor, fluid coupling has the function of connecting motor and reducer ,it replaces the mechanical coupling. The belt conveyor fluid coupling has two effects:
1.Overload protection
If the belt conveyor is overload, fluid coupling slip frequency increases, working fluid warms up, fluid coupling will spray without burning motor to a certain temperature. Of course sometimes coupling will be installed with a temperature control device, when work liquid superheats, temperature control device can control the motor and cut the power cut to protect the motor.
2. Flexible-start
When motor starts,belt conveyor starts slowly and acceleratedly , this can reduce the grid big impact to make the motor start up in light load. At the same time,it can reduce the effect of belt tension,protect belt and prolong life, especially under the heavy load start-up.

Installation and Notes of Belt Conveyor Anti-rain Cover

1) Open cover and fixed cover are manufactured with the galvanized steel plate or the colorized coating steel plate. Generally ,there will be 1 piece of open cover and 7 pieces of fixed covers installed every 8 pieces covers, the 2 kinds covers also can be installed side by side alternately ( it also can be matched according to customer’s requirement). At first, fasten the fixed conveyor with drilling rivets and based on the line which is upward 30mm from the top of Z type steel, fix a mounting hole every 450mm, every piece of cover overlaps 2 wave crests. Open cover overlaps above the fixed covers in order to open conveniently.

2) The Z type steel or the connection angle iron which is the main support frame of the conveyor cover, the length is equal to the length of the installed conveyor cover
The Z type steel or the connection angle iron is welded on the channel steel or the little stiffening angle iron on both sides of the conveyor

3) Install the covers (fixed covers) from one side to another side along the conveyor, during installation, people are not allowed to stand on the covers and no hard beating and hitting is allowed.
4) Mount the fixed covers on the Z type steel with the drilling rivet. The mounting points are not less than 4 on every piece.

5) 1 piece of observation window cover could be installed every 10 pieces for convenient checking and inspecting. It is decided by users.

6) Salient point cover is only used for the salient points of the convex-concave of the conveyor. Deviation switch cover is only used for covering the deviation switch. These 2 kinds covers also can overlap the fixed covers.

4. Note

1) During the installation, please handle the anti-rain cover carefully and avoid scratching.

2) After installing the accessories, please clean the surface and paint the scratched points again.
