PZXL型动态循环链码校验装置:
PZXL型动态循环链码校验装置是对安装在皮带输送机上的电子皮带秤进行动态校验的设备,广泛应用在电力、冶金、码头、建材、煤矿等使用电子皮带秤计量散状物料的场合。该装置可以实现对电子皮带秤精度的动态自动校验,通常用于校验准确度等级为(0.5)-(2.0)之间的各类电子皮带秤。
工作原理:
PZXL型动态循环链码校验装置安装在电子皮带秤现场附近,位于电子皮带秤秤体处的输送机上方,本装置能在带式输送机空载运转中,自动平稳地落放在皮带秤体上方的皮带上,由带式输送机拖动通过皮带秤的称量段,闭环的循环链码圈经装置机械传动,由带式输送机的拖动实现周而复始的循环运转,满拟输送物料的状态,以完成电子皮带秤准确度的动态校验。
设备组成:
◇方案一 当皮带秤与循环链码为一个项目时,其仪表、测速传感器可公用,以达到降低成本、提高可靠性并方便操作的目的。此时,循环链码主要由机架、标准链码、升降系统、电控系统等组成。
◇方案二 当循环链码为独立一个项目时,其主要由机架、标准链码、校验显示仪表、升降系统、测速传感器、电控系统等组成。
系统主要特点 :
◆ 链码随皮带同步运行,可近似模拟物料的输送特点,与实际运行状况的相似性,使得校验更直观可靠。
◆ 动态链码的收放或升降均由电控系统自动操作,根据用户需要,可设远方输出接点,供程控室远程校验。
◆ 校验过程中,校验仪表可显示标定值,并可将数据远传至集控室,以方便用户核校当前电子皮带秤计量的精度。
主要技术参数:

链码单位重量(kg/m):5、10、20、30、40、50、60、70、80、90、100、110、120、130、140、150、200

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
