弹簧钢
弹簧钢≤东≥≤莞≥≤国≥≤创≥≤金≥≤属≥≤材≥≤料≥≤有≥≤限≥≤公≥≤司≥弹簧钢主要是有好的弹性，又由于它是在动载荷环境条件下工作的，所以对制造弹簧的材质最主要的应有高的屈服强度；在承受重载荷时不引起塑性变形；应有高的疲劳强度，在载荷反复作用下具有长的使用寿命；并有足够的韧性和塑性，以防在冲击力作用下突然脆断。
弹簧在冲击、振动或长期交应力下使用，所以要求弹簧钢有高的抗拉强度、弹性极限高的疲劳强度。
在工艺上要求弹簧钢有一定的淬透性、不易脱碳、表面质量好等碳素弹簧钢即含碳量WC在0.6%-0.9%范围内的优质碳素结构钢。
合金弹簧钢主要是硅锰系钢种，它们的含碳量稍低，主要靠增加硅含量Wsi提高性能；另外还有硌、钨钒的合金弹簧钢。
近年来，结合中国资源，并根据汽车、拖拉机设计新技术的要求，研制出在硅锰钢基础上加入硼、铌、钼等元素的新钢种，延长了弹簧的使用寿命，提高了弹簧质量。
弹簧钢的用途：弹簧钢精度高,韧性好,耐磨性好,质量稳定。
主要的弹簧钢类,用途很广,可制造各种中等截面<25mm的重要弹簧,如汽车,拖拉机板簧,螺旋弹簧等60Si2Mn 55Si2MnB 55SiMnVB Cr系50CrVA淬透性优良,回火稳定性高,脱碳与石墨化倾向低；综合力学性能佳,有一定的耐蚀性,含V,Mo,W等元素的弹簧具有一定的耐高温性；由于均为高级优质钢,故疲劳性能进一步改善用于制造载荷大的重型大型尺寸（50~60mm）的重要弹簧,如发动机阀门弹簧,常规武器取弹钩弹簧,弹簧；耐热弹簧,如锅炉安全阀弹簧,喷油嘴弹簧,气缸胀圈等。
弹簧钢钢带产品适用于减振器阀片,离合器膜片弹簧,冷气压缩机阀片,针织机配件,沉降片,哈负片,织针,生克片,各种印刷刮刀,环形带刀等,五金冲压弹片,弹簧,发条,拉伸件,反弹簧高质量要求产品C45E钢材：●可以淬硬至HRC42~46；所以如果需要表面硬度，又希望发挥钢优越的机械性能，常将表面渗碳淬火，这样就能得到需要的表面硬度，常应用于机械制造S65C弹簧钢特性●：强度、硬度、弹性和淬透性均比65号钢高，具有水淬有形成裂纹他过热敏感性倾向，退火态可切削性尚好，应用于受中等载荷的板弹簧以及高耐磨性零件，如：磨床主轴、精密机床丝杆、弹簧卡头、切dao、螺旋辊子轴承上的套环、铁道钢轨等应用上C67S弹簧钢特性●：本产品是一款应用非常广泛的材料，多用于工作温度不高的小型弹簧或不太重要的较大弹簧，例如汽车、铁道车辆拖拉机及一般机械用的弹簧S70C弹簧钢：适用于制造截面不大、强度要求不高的弹簧，如汽车、拖拉机或火车等机械上承受振动的扁形板簧和圆形螺旋弹簧sk5-特性：特性及适用范围：淬火回火后有较高硬度和耐磨性,用作需要具有较高硬度和耐磨性的各种工具,如形状简单的模子和冲头,切削金属的刀具,打眼工具,木工用的铣刀,埋头钻,斧,凿,纵向手用锯,以及钳工装配工具,铆钉冲模等次要工具。

The two impellers are keyed directly to the motor rotor.CHIL evaporatorTrane developed an evaporator specially designedfor XStream Excellent chillers. Compact - High performance - Integrated design - Low charge (CHIL) evaporator optimizes the fl ow of the refrigerant to get an excellent heat exchange with water in every operatingcondition and minimize the quantity of refrigerant used; Features and benefitsVariable Primary FlowAn attractive chilled-water system option may be a variable primary fl ow (VPF) system. VPF systems present building owners with several cost-saving benefi ts that are directly related to the pumps. T he most obviouscost savings result from eliminating the secondary distribution pump, which in turn avoids the expense incurred with the associated piping connections (material, labor), electrical service, and variable-frequency drive.Building owners often cite pump related energy savings as the reason that prompted them to install a VPF system. With the help of a T RANE software analysis tool, you can determine whether the anticipated energy savings justify the use of variable primary fl ow in a particular application. It may also be easier to apply variable primary fl ow in an existing chilled-water plant. Unlike the “decoupled” design, the bypass can be positioned at various points in the chilled-water loopand an additional pump is unnecessary. T he evaporator in the XStream Excellent series can withstand up to50% percent water fl ow reduction as long as this fl ow is equal to or above the minimum fl ow-rate requirements. The microprocessor and capacity control algorithmsare designed to handle a maximum of 10% change in water fl ow rate per minute in order to maintain ±0.3°C leaving evaporator temperature control. For applications in which system energy savings is most important and tight temperature control is classifi ed as ±1.1°C, up to 30% changes in fl ow per minute are possible.Factory T esting Means T rouble-Free Start-up All XStream Excellent chillers are given a complete functional test at the factory. T his computer-based test program completely checks the sensors, wiring, electrical components, microprocessor function, communication capability, expansion valve performance, and fans. In addition, each compressor is run-tested to verify capacity and effi ciency. Where applicable, each unit is factory preset to the customer’s design conditions. An example would be the leaving-liquid temperature set point. T he result of this test program is that the chiller arrives at the job site fully tested and ready for operation.Factory-Installed and T ested Controls and Options Speed InstallationAll XStream Excellent chiller options are factory installed and tested. Some manufacturers send accessories in pieces to be fi eld installed. With T rane, the customer saves on installation expense and has assurance that ALL chiller controls and options have been tested and will function as expected.Superior Control with UC 800™ Chiller controlsThe Adaptive Control™ microprocessor system enhances the XStream Excellent chiller by providing the very latest chiller control technology. With the Adaptive Control microprocessor, unnecessary service callsand unhappy tenants are avoided. T he unit does not nuisance-trip or unnecessarily shut down. Only when the chiller controls have exhausted all possible corrective actions and the unit is still violating an operating limit, will the chiller shut down. Controls on other equipment typically shut down the chiller, usually just when it isneeded the most.Features and benefitsSmartFlow controlXStream Excellent series units are fully compatiblewith variable fl ow operation both on evaporator and condenser sides. T he modulation of the pump speedis managed to ensure that chiller ΔT stays constant. Entering and leaving temperatures at the evaporator will be measured directly by the chiller controller, through the factory-supplied sensor. A ΔT setpoint will be present on the unit controller. T he option for constant ΔT is intended to be used with 3-way valves on water systems, or 2-way valves on water system but constant fl ow at the by-pass.Series counterfl ow chiller confi guration When considering multiple chillers plant, designers conventionally go for parallel-piped chillersconfi guration. Nevertheless, there are ways to bring more effi ciency by using a different chiller lay-out.An effective alternative to consider is to pipe the chillers in series. Larger ΔT and low fl ow design save energyon the pumping. Series chiller confi guration allows as well, to get a better effi ciency from the upstream chiller, more lightly loaded. Combining this confi guration with Variable Primary Flow (VPF) will further increase system effi ciency.Series piping principle can also be applied tocondenser side. T his is called Series-Series counterfl ow confi guration. T his will result in similar advantageson the condenser side, enlarging the opportunity for savings on the overall system.For more information on Series chillers arrangements, refer to T rane Application Engineering Manual about Multiple-Chiller system design and control (SYS-AP M001).

高精度宽范围恒流源设计
高精度宽范围恒流源设计吴茂成(苏州大学物理科学与技术学院,江苏苏州215006)摘要:设计了一种由基准电压源、集成运算放大器及复合管等组成的高精度恒流源电路,其输出电流范围为1 A~1A。
详细分析了该电路的工作原理,公式推导证明了设计的正确性,并对实际应用中元器件的选取进行了说明。
对所设计恒流源电路的性能进行了测试,测试结果表明:该电路精度高、稳定性好,输出电流精度相对误差的最大值为0.152%,输出电流稳定性误差的最大值为0.047%。

GENERAL DESCRIPTION
The REF19x series precision band gap voltage references use a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy.
All electrical grades are available in an 8-lead SOIC_N package; the PDIP and TSSOP packages are available only in the lowest electrical grade. Products are also available in die form.

TEST PINS
Test Pin 1 and Test Pin 5 are reserved for in-package Zener zap. To achieve the highest level of accuracy at the output, the Zener zapping technique is used to trim the output voltage. Since each unit may require a different amount of adjustment, the resistance value at the test pins varies widely from pin to pin and from part to part. The user should leave Pin 1 and Pin 5 unconnected.
