◆用途和特点
2SB35系列为输出推力的电动执行机构,是西门子公司许可证技术的派生产品,是对闭环控制系统中最终控制元件(调节阀)的运行进行控制的一种装置,它可以准确的按控制指令对系统工况介质的压力、温度和流量进行自动调节,是实现自动控制的必不可少的驱动装置,可广泛用于电站、石化、冶金等工业系统。具有如下特点:
1. 设计先进、系列齐全、能充分满足电站等自动化控制的需要。
2. 结构合理、通用性强、可适应各种配套功能的需要,在2SB35上配装LU智能型功率换向模块时,即为智能型电动执行机构;配上MU(三相),MD(单相)即为数字型电动执行机构,为电站DCS技术提供了一种可靠的智能装置。
3.2SB35是2SA35系列的派生产品,所以2SB35系列具有2SA35的各种控制功能、并可提供二个以上的中途信号(即开、关向的中途信号)。
4.具有防尘防水性能、防护等级为IP67。应用户要求亦可提供防护等级为IP68的电动执行机构。
5. 调节方便、控制精度高。
◆技术条件

扬州博锐电动阀门有限公司是一家专业研制开发、生产销售阀门电动装置的综合型企业。
主导产品:西门子2SA3/2SB3/2SQ3系列电动执行机构、液晶显示遥控DZW多回转系列电动装置、DQW部分回转系列阀门电动装置以及电动阀门成套 钢厂、石油、冶金、化工、楼宇和给排水等自动化行业工程。
产品特点: 1、 全中文显示:一体化多回转电动执行器视窗采用高清晰LCD数字、全中文及标示符液晶显示屏。 2、 相序自动纠正:执行机构旋向可自由设定,也可自由校正电源相序。 3、 缺相保护:具有电源缺相保护功能。 4、控制模式:常规远方控制信号采用4~20mA模拟量信号控制,提供4~20mA信号反馈(可提供特殊量控制)。远方控制信号、反馈信号均与内部实现电气隔离。 5、 禁动延时保护:避免或减少了机械部分由于惯性承受的反作用力。此保护功能同时适用于现场控制方式和远控控制方式。 6、电子互锁保护:在一个指令正在执行且保持有效,再施加另一个反向控制指令时(即两个指令同时存在并有效),此时电动执行器将停执行完第一个指令后再执行下一个指令。 7、瞬间过力矩保护:当开或关向力矩瞬间被顶开,阀门将停下不动作,即使力矩开关瞬间顶开后闭合,阀门仍不会动作,只有向反向动作一下,即可解除过力矩保护。 8、现场远控切换:现场远控可自由切换,使用户调试、维护方便快捷。
博锐公司一直秉承“科技创新,科学管理,用户满意”的经营理念,得到各行业用户的认可,树立企业的品牌形象,创造电动阀门行业的精品。本公司遵循“建立体系、持续改进”的质量方针,本着“创新+质量+诚信+服务”的企业精神向广大用户提供优质的服务。、确保质量、按期交货、热情服务、顾客满意,质量第一系列、控制箱系列等品种规格齐全。广泛应用于电力、系列电动执行器、非侵入式系列电动装置、智能一体化系列阀门电动装置、防爆系列阀门电动装置、
Yangzhou vPro Electric Valve Co., Ltd. is a professional research and development, production and sales of electric valve actuators of the integrated enterprise. The main products: Siemens 2SA3/2SB3/2SQ3 Series Electric Actuators, LCD remote control series electric actuator, non-invasive series of electrical devices, integrated family of intelligent electric valve actuators, explosion-proof series of electric valve actuators, DZW multi-turn series electrical equipment, DQW part series of electric valve actuators and rotary valves complete series of electric control box series, with complete specifications. Widely used in electric power, steel, petroleum, metallurgy, chemical industry, building and automation industries such as water supply and drainage works.
Features: 1, all Chinese display: integrated multi-turn electric actuators with high-definition LCD digital window, all Chinese and identifier LCD. 2, automatically correct phase sequence: the implementing agencies to be free to set the rotation, but also free to correct power supply phase sequence. 3 phase protection: a power-phase protection function. 4, control mode: conventional remote control signal using 4 ~ 20mA analog signals, 4 ~ 20mA signal to provide feedback (which can provide special volume control). Remote control signals, feedback signals are internal to achieve electrical isolation. 5, cut-off fixed delay protection: to avoid or reduce the mechanical part of the bear because of the inertia reaction force. This protection also applies to on-site control and the remote control Control. 6, electronic interlocking protection: a directive is being implemented and remain effective, then put another reverse control instruction (that is, two instructions simultaneously and effectively), then actuator will stop implementation of the first instruction after completion the next instruction. 7, transient over torque protection: on or off to the moment when the moment is the top open, the valve will stop and not move, even if the torque switch instantly after opening the top closed, the valve will still not move, only to reverse action about that over torque protection can be lifted. 8, on-site remote control switch: on-site free remote control switch, allowing users to debug, maintain convenient. VPro has been adhering to the "scientific and technological innovation, scientific management, quality first, customer satisfaction" business philosophy, be recognized by various industries, establish a corporate brand image, create a boutique electric valve industry. The company is "the establishment of system, continuous improvement, ensure quality, on time delivery, warm service, customer satisfaction," the quality, the spirit of "Innovation + Quality + Integrity + Service" in the spirit of enterprise to provide customers with quality services.
