15.0 Hydraulic feeding system. (Moving floor).
Hydraulic moving floor, is the preferred feeding system in big installation , where the fuel are woodchip.
The fuel storage can be in the same level as the boiler room, or in the cellar, below the boiler room, we
just need to have in mind, that the tilted auger can work perfect, it the angle on the auger I bigger than
45°:
The hydraulic feeding system, include
the
following component:
1. From 1 up to 5 set of moving rams in
the fuel
storage.
2. The hydraulic cylinder
3. Hydraulic power pack
4. Fuel sensors to start the hydraulic
5. Fuel auger at the end of the storage
6. Tilted fuel auger max. 8m in 45°
Function:
1. When the boiler needs fuel, the
transport
auger will be started.
2. If the fuel sensor over the bottom fuel auger, give the signal ”empty” The lamp on the screen for the
sensor, will change to green
3. Hydraulic unit start and the lamp on the screen for the sensor, also change to green
4. The Hydraulic cylinder start to move.
5. When the ram reaches the end, the hydraulic pressure will rise, and the pressure controlled valve will
change the oil flow, and the cylinder will change direction.
6. When the sensor is activated by the fuel, the hydraulic stop again.
The fuel sensors are placed in set with 2 sensors by each cylinder, the left sensor are the
master, and the right the slave
The sensor we use indicate with a red light, the measure point, that is very handy, when we
adjust the sensor.
On the picture below, it is possibly to see this red light from the sensor, but a bit weak in the
flash light from the camera.
