丹佛斯-自动控制产品介绍
各种阀的主要特性
PM主阀工作原理
PM主阀是一个伺服控制的阀门。它的功能是由 导阀决定的。根据所接的导阀，PM主阀可以实 现开关调节，比例调节，比例积分调节等诸多调 节功能，他特别适用于制冷系统的温度、压力控 制。
PM主阀的开度由作用于活塞上下的压差 （△P=P2-P3）所决定。
当△P<0.07bar时，主阀将处于关闭状态
阀的螺旋阀杆由步进电 动机直接驱动。没有传 动装置，可以精确控制 阀杆移动的位置。
这种设计，可以确保即 使在很低的负荷工况下 烦闷打开的精度
EVR/EVRH 电磁阀
属于常闭型，直动式或伺服式电动机，用 于氟化物制冷剂的液体管路，吸气管路， 热气管路。
线圈通电后，电枢被电磁力吸起，当进入 线圈磁场时，阀直接全开，这意味着工作 允许的流体最小压力差为零。
具有背封功能，可在运行时更换密封函
采用聚四氟乙烯阀板，使阀在关闭时具有可靠地 密封性能
SFA 安全泄压阀
属于背压式的泄压阀，SFA15、SFV20、 SFV25安全阀设置的开启压力在10和 25bar之间，可作为内部安全阀使用
适用于R717在内的各种不可燃制冷剂及 无腐蚀性的气体，液体，但要注意密封性
ETS6
通过螺旋机构的线性运 动实现开启与关闭，当 线圈通电时，磁针阀转 动，螺旋机构线性运动， 在线圈机构内，存在不 同的绕组配置，极性由 施加的电信号改变。当 以脉冲形式施加适合的 组合信号时，线圈迫使 阀转子步进
精确定位确保冷媒喷入量的最优控制
大冷量范围可供选择
平衡流口设计，可进行双向流操作，在MOP为33bar时， 和电磁阀一样紧密的双向开关功能
当储液器的压降下降，KVD压力调节 器打开，通过热气旁通阀保证储液器 内的压力与设定值一致

The differential is fixed at 0.1 bar, i.e.the alarm will not cut out before the pressure rises to 0.9 bar. The lamp must be connected to terminals 1 and 2 in the pressure control.Example 2An alarm must be given by a bell when the pressure in a boiler rises to 10 bar. The normal operating pressure is 9 bar.Choose a KPS 36 (range from 6 to 18 bar).The range value of the pressure control must be set at 10 bar, the differential at 1 bar.The bell must be connected to terminals 1and 4.Example 3The pressure in a start air reservoir must be regulated with a compressor controlled by a KPS pressure switch so that it lies between 30 and 36 bar.Choose a KPS 45 (range 4 to 40 bar).The range value must be set at 36 bar.The differential of 6 bar must be set in accordance with the nomogram, fig. 10, at approx. 2 on the differential scale.The required start function is obtained by connection to terminals 1 and 2 in the pressure control.Mechanical differential Mechanical differentialFig. 8Fig. 98DKACT.PD.P10.E2.02Danfoss A/S 10-2003Pressure switches and thermostats, type KPSEN 60 947-4-1EN 60 947-5-1–10- 30 3-10 80 65 75 110 160 2060L3112 060L3113 KPS 7620- 603-14130-75---060L3118KPS 7720- 603-14130--110--060L3100KPS 7720- 603-14130--160-060L3136KPS 7720- 603-1413065751101602-060L3101060L3102KPS 7720- 603-14130--1101605060L3119060L3120KPS 7750-1004-16200 -75---060L3121KPS 7950-1004-16200--110-060L3103KPS 7950-1004-16200160060L3137KPS 7950-1004-1620065751101602060L3104060L3105KPS 7950-1004-16200--1101605060L3122060L3123KPS 7950-1004-16200--1101608060L3124060L3125KPS 7950-1004-16200-751101603060L3143KPS 7950-1009200-75---060L31411)KPS 7970-120 4.5-18220-75---060L3126KPS 8070-120 4.5-18220--110--060L3127KPS 8070-120 4.5-18220---160-060L3138KPS 8070-120 4.5-18220---200-060L3157KPS 8070-120 4.5-1822065751101602060L3128060L3129KPS 8070-120 4.5-18220-751101603060L3156KPS 8070-120 4.5-18220--1101605060L3130060L3131KPS 8070-120 4.5-18220--1101608060L3132060L3133KPS 8060-1505-2525065751101602060L3106060L3107KPS 8160-1505-25250--1101605060L3134060L3135KPS 8160-1505-252501101608060L3111KPS 8160-1505-25250200060L3110KPS 81100-2006.5-3030065751101602060L3108060L3109KPS 83100-2001830065751101602060L31391)060L31401)KPS 83Thermostats, introductionKPS thermostats are temperature-controlled switches. The position of the contacts depends on the temperature of the sensor and the set scale value. In this series, special attention has been given to meeting demands for : a high level of enclosure,robust and compact construction, resistance to shock and vibration.The KPS series covers most outdoor as well as indoor application requirements.KPS thermostats are suitable for use inmonitoring, alarm and regulation systems in factories, diesel plant, compressors, power stations and on board ship.KPS with rigid sensorKPS with remote sensorKPS with remote sensor and armoured capillary tube Approvals 1) Thermostat with max. reset.When ordering, please state type and code numberTechnical data and ordering Ship approvalsDet norske Veritas, Norway American Bureau of Shipping Lloyds Register of Shipping, UK F Germanischer Lloyd, Federal Republicof Germany (FRG)Bureau Veritas, FranceIncludes thermostats with fixed sensor and pressure controls with armoured capillary tube.U Underwriters Laboratories Inc., USA Registro Italiano Navale, Italy PPolski Rejestr Statków, PolandMRS, Maritime Register of Shipping,RussiaNippon Kaiji Kyokai, J apanCode nos.Mech.Max.Suitable Cap.Setting diff.sensor sensor length Tube Typerangeadjustable/temp.(see also lengthfixed“Accessories”)°C °C °C m m m9DKACT.PD.P10.E2.02Danfoss A/S 10-2003Pressure switches and thermostats, type KPSKPS 76:±3 °C KPS 80:±3 °C KPS 77:±3 °C KPS 81:±6 °C KPS 79:±3 °CKPS 83:±6 °CFig. 1Curve A gives the maximum load.Hatched area B: Acceptable load for the gold plating of the contact.Contact load (Alternating current):Ohmic:10 A, 440 V, AC-1Inductive: 6 A, 440 V, AC-34 A, 440 V, AC-15Starting current max. 50 A (locked rotor)Ambient temperature –40 to +70 °C Vibration resistanceVibration-stable in the range 2-30 Hz,amplitude 1.1 mm og 30-300 Hz, 4 G.EnclosureIP 67 to IEC 529 and DIN 40050.The thermostat housing is enamelled pres-sure die cast aluminium (GID-AlSi 12).

Therefore function is not affected whether the sensor is placed warmer or colder than the remaining part of thethermostatic element (bellows and capillary tube). However, such a charge is to some extent sensitive to changes in thetemperature and bellows and capillary tube.Under normal conditions this is of noimportance, but if the thermostat is to be used in extreme ambient temperatures there will be a scale deviation. The deviation can be compensated for as follows:Scale correction = Z × aZ can be found from fig. 4, while a is the correction factor from the table below.Correction factor a Regulation for thermostats Typerangewith with with rigid 2 and 5 m 8 m °Csensor cap.tube cap.tubeRelative scale setting in %Electrical connectionKPS thermostats are fitted with a Pg 13.5screwed cable entry suitable for cables from 5 to 14 mm.

An alarm must be triggered if the cooling water temperature exceeds 95 °C.Choose a KPS 80 thermostat (range 70 to 120 °C).Main spindle setting: 95 °C.Differential spindle setting: 5 °C.The required alarm function is obtained by connecting to thermostat terminals 1-4. After the system has been in operation, assess the operating differential and make a correction if necessary.Example 2Find the necessary scale correction for a KPS 80 set at 95 °C in 50 °C ambient temperature.The relative scale setting Z can be calculated from the following formula:Setting value – min. scale value max. scale value – min. scale valueRelative scale setting: 95 – 70× 100 = 50%120 – 70Factor for scale deviation Z (fig. 4 page 11),Z ≅ 0.7Correction factor a (table under fig. 4page 11) = 2.4Scale correction = Z × a = 0.7 × 2.4 = 1.7 °C The KPS must be set at 95 + 1.7 = 96.7 °CScale deviation factorFig. 4Fig. 5× 100 = %12DKACT.PD.P10.E2.02 Danfoss A/S 10-2003。

丹佛斯压力控制器原理与应用调节方法
丹佛斯压力控制器原理与应用调节方法压力控制器是传统制冷设备、冷库机组不可或缺的压力配套检测保护器件。
在众多的压力控制器品牌中，丹佛斯使用广泛、保护性能稳定，受到制冷行业工程设备商的青睐，但是该压力控制器属于国外知名品牌，如果对其产品特点不了解或了解不够深入，就会给使用、调试、替换等带来一定的困难，笔者结合自身对该产品使用心得撰文，以供同行参考，避免走弯路!丹佛斯压力控制器常用的有三种，分别为KP1型(低压压力控制器)、KP5型(高压压力控制器)、KP15型(高低压压力控制器)。
这些压力控制器中有自动复位或手动复位功能，以及回差调节款和恒定压差款等。
本文以工程中应用最广泛，由波兰共和国(POLAND)或印度(INDIA)制造的KP1、KP5以及KP15为例，逐一进行技术分享 !丹佛斯采用的压力单位为bar(巴)或psi(磅/平方英寸)，为了便于读者换算以及结合在国内常使用压力单位实际情况，本文全部采用传统的kgf/cm²为单位进行撰文表达，其转换式为:1k gf/cm²= 1bar=14.5psi。
一、KP1压力控制器KP1压力控制器如图1所示，是一款低压压力控制器件，主要用于防止制冷系统低压压力过低保护。
该款为自动复位型控制器。
1.内部面向用户的主要结构框图拆开KP1的顶盖和前外壳后，如图2所示，面向用户的主要有压力显示刻度盘、低压压力及低压回差压力调节螺杆、接线端子等。
2.低压压力控制器工作原理KP1压力控制器冷媒接入口(1/4英寸喇叭口连接)，接至制冷系统的低压侧，制冷设备工作时系统的低压侧压力会实时传送至压力控制器，如果检测到压力比设定的压力值高，说明系统正常(正常时:接线部位的1、4端口接通)，KP1电气原理示意图如图3所示。
如果检测的压力比设定的压力值低，说明系统低压压力过低(例如冷媒泄漏、干燥过滤器、毛细管、热力膨胀阀堵塞等都会导致低压压力过低)，为了保护压缩机，不至于在压力过低或者没冷媒的系统中运行时，导致压缩机温升过高、磨损加剧、加速老化等，所以一旦检测到低压压力低于设定值时，就会报警保护，触头1、4断开，切断压缩机电路，1、2接通促使指示灯或喇叭得电报警等，使压缩机保护停机等，实现低压过低保护功能。

danfoss三通阀门使用说明
danfoss三通阀门使用说明Danfoss三通阀门是指采用高强度不锈钢、合金、陶瓷等材料制成的一种阀门。
其主要特点在于强度高、耐磨损、寿命长。
特别适用于化工、石油、冶金、机械等行业。
本阀门的使用寿命一般为40-50年左右，在使用过程中如出现漏水等问题应及时检修，避免造成不必要的损失。
1. Danfoss三通阀门不允许用手直接接触阀门内的介质，否则将损坏阀门结构。
如必须接触时，应注意防止液体飞溅到阀体上，造成损坏。
当阀门开启时，手不能接触到阀门内部，请使用其它保护工具对阀门进行检修。
由于阀门内部泄漏或损坏引起阀门关闭不严密或停止工作时，使阀门处于关闭状态。
如操作不当将会造成泄漏或损坏阀门内部元件。
2.阀门安装前应检查各零件、管件是否完整以及内部有无油污、铁锈等。
在安装阀门前，必须先清洗管道和阀门，以免安装时出现卡塞等现象。
安装阀门时，应使阀门置于合适的位置。
阀门的密封面和球面之间的间隙应保持在1-2 mm内，以免影响密封效果。
在安装阀门前一定要将阀门打开检查密封是否完好。
在管道上安装阀门时应尽量减少阀门之间的距离。
阀门的安装方向应与管道上安装阀门时所选定的方向一致。
关闭时阀门应处于开启状态。
安装阀门后应进行检验，确保密封性能良好。
阀门应有良好的密封性能，且密封面不得有砂眼、气孔、裂纹、疏松和缩孔等缺陷，密封性能应符合表1-3要求。
3.在安装过程中应注意的是必须安装好法兰和垫片，以免阀门因振动、冲击而损坏。
如果没有法兰和垫片，可以安装在法兰上，也可以安装在阀门上。
安装时要注意法兰上与阀门壳体垂直、相互平行，在安装时应使阀门在水平位置，不能与管道平行以免影响阀门的密封。
安装法兰和密封垫片时应注意保证法兰的密封面和垫片压紧，以免阀门因振动、冲击而损坏。
Danfoss三通阀门使用说明对阀门各部位的安装要求严格执行下列规定：首先要进行预处理在阀门安装前应对管道和阀门内部进行清洗，检查是否存在污物、异物等杂质。
