Application of hydraulic coupler in conveyor
Hydraulic coupler is a kind of energy transmission device, in the work is mainly liquid oil as the medium, through the mutual transformation of mechanical energy and kinetic energy, so as to achieve mechanical operation.
Fluid couplers are also used on conveyors, so what role does it play on conveyors? Let's see.
Belt conveyor is a constant load machine whose power consumption mainly depends on the geometric layout of belt conveyor.
Long horizontal belt conveyors have relatively large moment of inertia (equivalent to the input shaft of the reducer), and large inclination belt conveyors must overcome power consumption caused by height difference.
Different from the scraper conveyor, the load of the belt conveyor will not change when it is stopped, and the belt conveyor will not be blocked.
If blocking occurs, the roller will slip under the conveyor belt.
To protect the conveyor belt (the most expensive part of a belt conveyor) from longitudinal fluctuations and peak moments.
Driving torque should be limited to the minimum that can be used to accelerate the conveyor belt.
In this way, the controller's role is to record the load of the conveyor belt (that is, to save the power requirements at the last rated condition, store it in memory and use the value at the next starting).
The control parameter here is the motor power and the corresponding motor current.
In addition, the motor output speed needs to be monitored in real time.
In addition, if the starting time is long (at present, the maximum starting time of ground belt conveyor is up to 7.5min), each driver shall achieve load balance when necessary.
Another important feature of belt conveyors that are driven in the middle of the belt (either by force or by linear force) is their active control with load.
That is to say, the torque should only be transmitted to the load section of the conveyor belt, because only that part requires power to move the load.
At this time, the transfer torque of the no-load segment should be reduced, so the return segment cannot pull the conveyor belt, and the return segment will generate excessive tension.
