柜内机架卸载汇线槽的安装


柜内机架卸载汇线槽的安装 机组控制系统主要由过程控制单元、操作员工作 站、数据通信接口等构成,通常,过程控制单元采用可 编程序逻辑控制器(PLC),做为人机界面的操作员工作 站采用带触摸屏的计算机。自动、连续地监视和控制压 缩机组及其辅助系统的运行,保证人身和设备安全。具 体来说,该系统至少满足以下性能:根据命令或条件, 按预定程序自动完成机组的启动、加载、卸载和停机/ 紧急停机等操作;

Unit control system is mainly composed of process control, data communication interface unit, the operator workstation, etc, in general, the process control unit adopts the programmable logic controller (PLC), the operator workstation with touch-screen as the man-machine interface of computer. Automatically and continuously monitor and control the operation of the compressor unit and its auxiliary system, to ensure personal and equipment safety. At least meet the following performance: specifically, the system according to the command or conditions, in accordance with

the scheduled program automatically unit start-up, loading, unloading and stop/emergency stop, etc;

在所有工况下执行对机组的保护; 在系统故障或误 操作的情况下避免不安全的因素发生; 在触摸屏上显示 各种工艺变量及其它有关参数;提供声光报警;与 SCS 交换信息;接受 SCS 的操作命令。全自动的完成对机组 及其辅助系统和相关联部分的监控,如(但不局限于 此) :启动/停机顺序控制(包括各个阀门的顺序控制) ; 负荷控制;

In all conditions to protect the unit; In the case of system failure or incorrect operation avoid unsafe factors; On a touch screen display various process variables and other relevant parameters; Provide sound and light alarm; With the SCS to exchange information; Accept the SCS operation command. Automatic completion of unit and its auxiliary system and the associated part of the monitoring, such as (but not limited to this) : start/stop sequence control (including the sequence control valve); Load control;

动力源控制(如电源等) ;速度控制及保护停机; 机组机械状态监测及保护停机; 就地控制柜通常包括触 摸屏、开关、按钮、指示灯、24VDC 电源等。就地控制 柜选用钢质双门或单门标准尺寸柜,门上带安全锁。控 制柜配备散热通风、照明等设施。控制柜的设计充分考 虑了草莓苗机柜内部和外部电线/电缆的布线空间。

Power control (such as power supply, etc.); Stop speed control and protection; Unit downtime machinery condition monitoring and protection; Local control cabinet usually include touch screens, switch, button, indicator light, the 24 VDC power supply, etc. Local control cabinet choose steel two-door or single standard size cabinet, with safety lock on the door. Control cabinet is equipped with a cooling ventilation, lighting and other facilities. Control cabinet design fully consider the internal and external wire/cable rack wiring space.

柜内机架与端子排的布置考虑了扩展余地且方便

维护、检修,柜内布线全部通过汇线槽,柜下端安装接 地母线。控制柜满足所处环境的防爆等级要求。用户负 责向控制柜提供符合要求的电源:220VAC,1Ph,50Hz。 供应商提供 24VDC 备用蓄电池。蓄电池安装在控制柜 内。 就地控制柜负责向发动机控制系统提供 21.6-30VDC (最大尖峰电压 2V,最小电流 12Amps) ,用于发动机控 制和点火。同时,泰山雄风向控制面板和末端设备提供 16 Amps 电流,向成套撬装电磁阀提供 24 VDC。

Enclosure frame to the layout of the terminal row and considering the scaling and convenient maintenance, overhaul, all wiring through trough inside ark, cabinet bottom grounding bus bar installation. Controller can satisfy the demands of environment explosive-proof grade. User is responsible for providing meets the requirements of power supply to the control cabinet: 220 vac, 1 ph, 50 hz. Suppliers provide the 24 VDC backup battery. Battery installed in the control

enclosure. Local control cabinet is responsible to the engine control system to provide 21.6-30 VDC (minimum rush 2 v voltage, maximum current 12 amps),
