The PZXL type dynamic circulation chain code checking device is a kind of equipment for dynamic checking of the electronic belt scale installed on the belt conveyor, which is widely used in electric power, metallurgy, wharf, building materials, coal mine and so on. The device can realize the dynamic automatic calibration of the accuracy of the electronic belt scale, which is usually used to verify all kinds of electronic belt scales between (0.5)-(2.0). Working principle: The PZXL type dynamic circulation chain code checking device is installed near the electronic belt scale field, located above the conveyer at the electronic belt scale body, the device can automatically and smoothly fall on the belt above the belt scale body in the no-load operation of the belt conveyor, the belt type conveyor drags through the weighing section of the belt scale, the closed-loop chain code circle is driven by the device, and the belt type conveyor realizes the cycle cycle operation to meet the state of the simulated material, in order to complete the dynamic check of the electronic belt scale accuracy. Equipment composition: Scheme 1 When the belt scale and the cycle chain code are a project, its instrument and speed measurement sensor can be used to reduce the cost, improve the reliability and facilitate the operation. At this time, the cycle chain code is mainly composed of frame, standard chain code, lifting system, electric control system and so on. Option 2 When the cycle chain code is a separate item, it is mainly composed of frame, standard chain code, calibration display instrument, lifting system, speed measurement sensor, electric control system and so on. Key features of the system: The chain code runs synchronously with the belt, which can simulate the conveying characteristics of the material and make the check more intuitive and reliable. The collection and drop of the dynamic chain code are operated automatically by the electronic control system. According to the needs of the user, remote output contacts can be set up for remote verification in the program control room. ◆ the calibration process, the calibration instrument can display the calibration value, and the data can be transmitted to the to facilitate the user to check the accuracy of the current electronic belt scale measurement. Main technical parameters: Chain code unit weight (kg/m):5,10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,200 Chain code accuracy: MII level Accuracy of system :±0.1% Measuring Belt Scale Capacity :1~6000 t/h Suitable Conveyor Belt Width :500~2200 mm Total power :4 kw; Instrument output interface: RS232/485,4-20mA, solid state relay pulse output Working environment requirements: ◆ ambient temperature: instrumentation -10℃-60℃, machinery -35℃-65℃; ◆ power supply: metering system and control circuit 220 VAC(10%/-15%),50HZ(±2%) 380 VAC(10%/-15%),50HZ(±2% of lift and lift parts
