Static weighing ,Multi-access, low price
3N800PFC automatic constant feeding system
Device and work principleLoad vibrator B loads materials from silo A into the bucket C. Increasing materials checked by high precise load cell. After calculated by 3NSAC0152, this varies signal send to 3N800 controller..
In 3N800 controller, this electrical signal is calculated into weight with a standard unit (Kg, ton, Lb). So the controller measures the weight of loaded materials in bucket and compare with pre-set target. As soon as the weight up to target, load vibrator stop. The controller sends a discharge signal to XK35PC executor. The executor drives electromagnet F to open discharging gate and let the materials out. This procedure repeats.
There is a compensation algorithm in the control system. It automatically corrects the discharging weight in every cycle in case of error occurs. That makes a high precise weighing and feeding.
2. Device Description
2.1 A 3N800 can control 1～16 bucket scale at the same time.
2.2 Every bucket scale including (probably more than one scale in one system):
1 Load vibrator (for powder material, it is screw feeder)
1 bucket scale
1～3 Load cells
1 wiring box (Not necessary in some cases)
1 3NSC0152 unit
1 3NXK35PC unit
35 meters of Shielded cable
1 accessories assembly
2.3 3N800 controller including (for one system):
1 3N800 host
(Chinese/English)
1 LCD monitor
1 waterproof keyboard KBD70A
1 control cabinet and console
2.4 Safeguard Grade:
Control cabinet: IP54.
Load cell: 3NSAC0152, KBD70A: IP65.
2.5 The capacity of the vibrator and bucket scale are determined according user requirement. The data below is needed by users:
A: For every kind of materials, the normally flow (ton per hour) and characteristic (granularity).
B: How many
kind of materials, and in nature, the weight per stere (unit: t/
)
2.6 Precision: ±0.5%
2.7 The capacity of one scale: 0.1t/h～300t/h
Notice: Not allow the electromagnet piece to be connected overtime. That will be overheat and cause damage.
