压力试验机安装不正确产生的误差压力试验机安装不水平，会增加各活动部件之间的摩擦力，影响垂直安装，从而给试验机带来误差。主机部分安装不水平工作活塞和工作油缸之间将会产生摩擦力，压力试验机工作平台与一侧立柱之间的导轮也会产生摩擦力，从而产生误差，一般表现为正差，且误差随着载荷的增大而减小。测力计部分安装不水平若测力计前后安装不水平，将会使摆轴轴承之间产生摩擦力，其误差一般表现为负差。综合以上两种因素产生误差的特点都是对小负荷影响大，对大负荷影响小。摩擦阻力产生的误差主机部分摩擦阻力液压压力试验机的摩擦阻力主要发生在工作油缸和工作活塞之间。除安装不水平因素外，油缸内有脏物，油的粘度过大，也会造成摩擦阻力加大。另外，工作平台导轮位置不合适也会造成与一侧立柱的摩擦力增大。测力计部分摩擦阻力测力计产生摩擦阻力的原因较多，如测力油缸与测力活塞之间有脏物，油的粘度过大，指示装置上的从动针摩擦力大，齿轮齿杆上有油污、脏物或齿杆上限位片压得过紧，测力活塞皮带磨损断裂等。2气液触摸界面的部分接连与立体接连在曝气技能中，液相流体自动运动类型有如下三种根本办法：叶轮搅动曝气池水体外表；转刷或转盘转变处发生水跃；射流流出。由曝气池立体性质方面看，上述三种液相流体自动运动所构成的气液触摸面，都具有一个一起的特征即是部分接连；即仅只在被搅动的水体外表或射流口邻近发生气液触摸界面。气相流体自动运动则不一样，空气由曝气池池底在重力推进之下以升泡的办法向上作运动，升泡在上升过程中要不断与水体发生触摸，因而其构成的气液触摸界面即是立体接连。消除方法对于以上误差的出现，应首先检查压力试验机安装是否水平，对主机用框式水平尺在工作油缸外圈相互垂直的两个方向找平。对测力计在摆杆正面调整测力计前后水平，将摆杆边缘与内侧刻线对齐固定，用水平尺靠在摆杆侧面调整机体左右水平。对油缸内脏物可放油清洗并更换粘度适宜的机油。测力计指示装置从动针摩擦力过大，齿轮齿杆过脏，可用汽油清洗并调整压紧螺丝及齿杆上限位片，更换测力活塞上的皮带，这些都可以达到消除误差的目的，使试验机达到合格使用状态。

回风系统中的问题在压力控制方面，回风系统的设计很重要，特别是回风口的计算。要合理的布置回风口，应的考虑净化系统的综合性能。回风系统的设置不单要把回风引回循环机组，还要参与系统压力的控制。设计中突出的问题是片面强调房间内的气流分布均匀，从而盲目的增加回风口的数量，大量使用相同尺寸的回风口。由于回风口面积的增大，无形中增加了回风量的控制难度，易导致正压无法形成。第二：新风系统中的问题计算新风量时不能忽略整个系统的泄漏量问题，理论计算值和实际测定值的差别有时相差很悬殊，这和工程的各个环节有关。

IEC6364标准规定，2类场所内用于维持生命或外科手术的电器设备，额定电压超过AC25V或DC6V的设备，必须使用带绝缘监视仪的IT电源系统。绝缘监视仪安装在IT系统和大地之间，IT系统发生接地时，绝缘监视仪立刻发出报警信号，通知操作人员系统已经带故障运行，必须尽快找出故障，以便在发生第二点接地之前排除故障。对于2类场所的IT系统内安装的绝缘监视仪，除了必须符合绝缘监视仪的通用规范IEC61557-8标准以外，还必须符合IEC6364-7-71标准的特殊要求：内部交内阻抗应至少为1k；测试电压不应大于直流25V；即使在故障条件下，其注入的电流的峰值不应大于1mA；迟在绝缘电阻降至5k时，应发出信号。

RO机废水问题不容忽视在越来越多的民众享受以RO反渗透膜为核心的纯水机所生产出的净水时，他们又不得不面对这样一个现实问题，即RO反渗透纯水机在制取净水的同时亦产生了大量的废水，由于这些废水得不到合理的使用而白白的被直接排放掉，进而造成自来水的极大浪费，这显然是与所倡导的节能减排、节约用水的理念违背的。目前，采用这种技术生产的机器设备主要有两种，即家用型的RO反渗透纯水机和社区户外安装型的RO反渗透制水售水机。
