1.描述

离岸经营的立场是用来改进，确保压脚正平行试样表的准确性和模拟和数字硬度硬度计读数的重复性。Any round analog or digital durometer can be mounted on an applicable operating stand.任何一轮模拟或数字硬度可安装在适用的经营场。展位的工作主要是为双方与并行测试样本使用。Irregularly shaped objects may be tested in a nest or a fixture to make the given surface parallel to the Durometer presser foot.形状不规则的物体可能是在测试巢或夹具，使定表面平行的硬度压脚。

ASTM D2240规定三类经营站：1类，2类，3。Type 1 are basic, manual operating stands.第1类是基本的，手动操作站。Type 2 are stands capable of controlling the rate of descent, and Type 3 are hydraulically, pneumatically or electromechanical driven.类型2的代表能够控制的下降率，和类型3的液压，气动和机电驱动。Shore manufactures stands that fall into all 3 categories.站在岸上生产纳入所有3个类别的下降。

2.操作原理

人工站几种型号可供选择。The LR leverloader features a constant load weight for highly accurate and reproducible hardness readings.土地注册处leverloader具有高度准确，重现性硬度读数恒定负载的重量。To operate, the lever is depressed to raise the specimen to the durometer, which in turn lifts a constant load weight seated on a shaft above the instrument.操作，杠杆低迷提高试样的硬度，从而升降机恒定载重量在上述文书轴就座。The mass of the durometer and instrument shaft assembly in combination with the small weight produces the mass necessary for Types A, B, and O durometers.的硬度和组合仪表轴装配质量的小重量群众的生产类型的A，B和O硬度必要的。The addition of the large weight produces the mass necessary for Types C, D, and DO durometers.在大重量除了大规模的生产类型的C，D，做必要的硬度。The durometer and instrument shaft assembly produces sufficient mass for testing with Type OO durometers.硬度和仪器的轴装配生产用于面向对象型硬度测试足够的质量。

在硬度应用速度的变化是不同的硬度读数的共同事业。For example, when testing materials with high creep properties, you may obtain a false high reading if you apply the durometer too quickly to the material.例如，当高蠕变性能测试材料，您可能会得到一个错误的高读数如果你申请的硬度太快的物质。The CV conveloader features a constant load weight and a hydraulic cylinder that automatically controls the application velocity of the durometer.该简历conveloader具有恒定负载重量和液压缸自动控制的硬度应用速度。When you release the pawl lever, the weight drives the durometer downward at a steady rate, controlled by the calibrated bleed resistance of oil through the hydraulic piston.当您松开棘爪杆，重量硬度下降的驱动以稳定的速度，由校准流血通过液压活塞耐油控制。The durometer contacts the specimen at a constant speed and force, ensuring repeatable and accurate test results.接触的硬度试样以恒定的速度和力量，确保可重复和的测试结果。

DR和DRCL（何恒定负载）代表提供一个稳定的安装和测试模拟或数字硬度夹具。Both models allow you to adjust specimen table and durometer heights.这两种型号允许你调整样本表和硬度高。When a durometer is mounted and properly aligned, the durometer's presser foot is exactly parallel to the specimen table on the stand, ensuring accurate and repeatable readings.当安装和硬度是对齐的硬度的压脚，正是平行试样表上的立场，确保准确和可重复的读数。The DR stand requires that you manually lower the durometer and then apply appropriate pressure to the specimen.在何立场需要您手动降低硬度，然后采用适当的压力，试样。In contrast, the DRCL stand provides a loading weight of known value for this purpose.相比之下，DRCL立场为此提供了一个已知值装载重量。
