1. cdlf泵
意思就是变频增压泵。变频离心泵是采用南方CDLF/CDMF或CHL系列轻型不锈钢离心泵并增加智能PLC变频供水控制系统。
2. cdlf泵外形
首先确定选用多级泵。
推荐GDL立式多级泵（普通）、CDLF立式不锈钢多级泵（高档）。
扬程=高度*1.2+20m=32*3（3m/层）*1.2（管路损失，镀锌管管路用DN150，弯头4-5个）+10（32层末端留10m水头压力）=115m
流量：选用18m³/h
型号推荐：1.50GDL18-20X6 流量18m³/h，扬程120m，功率11kw
2.CDL20-10 流量20m³/h，扬程118m，功率11kw
推荐选用：变频控制柜（变频器选用瑞士ABB），压力可以随着盖得高度设定，比如10层内，设定为50m；20层内，设定为80m，以此节能。
3. cdlf泵参数
区别
CDL适用于无腐蚀性液体,CDLF适用于轻度腐蚀性液体。供水:水厂过滤与输送、分区送水、主管增压、高层建筑增压。工业增压:流程谁系统、清洗系统、高压冲洗系统、消防系统。工业液体输送:冷却空调系统、锅炉给水和冷凝系统、车床配套、酸和碱。水处理:超滤系统、反渗透系统、蒸馏系统、分离器、游泳...
4. cdlf泵是什么意思
一、CDLF 型立式多级泵产品介绍: CDLF 型立式多级泵(以下简称多级泵)是吸取了国内外先进技术而设计制造的非自吸 立式多级离心泵,采用标准立式电机和快装式机械密封,更换非常方便。
泵的过流部分均采用(304\316)材料制成,可适用于轻度腐蚀性介质。该产品可替代 国外 CR、CRN 等同类产品。产品投放市场后,以其高效节能、质量可靠、使用范围广等特 点。
二、CDLF 型立式多级泵技术参数: 流量:4.2-504m3/h; 扬程:24-240m; 功率:1.5-450kw; 转速:2900r/min; 口径:φ 40-φ 250; 常温型:-15℃-+70℃; 热水型:-15℃-+120℃; 工作压力:≤2.4Mpa。
5. cdlf泵型号说明
CDLF是不锈钢冲压泵的一个通用型号。
4代表流量四立方/小时。5是级数，也就是说有5个叶轮。1.1是电机功率。6. cdlf泵图片
CDL/CDLF是一种不锈钢立式水泵，可以输送从自来水到工业液体的各种不同介质，适应于不同温度、流量和压力范围，CDL适用于无腐蚀性液体，CDLF适用于轻度腐蚀性液体(过流部件表面有氟塑料)

广场舞当下很受广大众的欢迎，无论男女老少都可以参与其中，不仅可以锻炼身体、娱乐身心，还可以认识到很多朋友。广场舞不同于专业舞蹈，有学习容易、内容简单、实用性强等特点，那么一起来看一下广场舞的教程吧！
广场舞简介
广场舞按类型分，主要分为中老年秧歌、腰鼓、扇子舞、伞舞、球操等。按步法来分，大众广场舞主要有为12步、16步、 18步、 20步、22步、 24步、 26步、27步、30步、 34步、 36步、 37步、40步等等，最多的达200-300步。
舞步教程详解
按类型分
中老年秧歌
中老年秧歌舞视频教程可以参考：【中老年秧歌舞《大妈扭得美》64步欢快喜庆】 https://b23.tv/wjXOrOb【秧歌广场舞《大姑娘美大姑娘浪》正背面附教学】 https://b23.tv/cEd27c6
动作要点：首先左脚往右前方交叉过来，再右脚往左前方交叉过来，接着左脚退回去，右脚并过去。
腰鼓
腰鼓舞，均穿彩服，腰间挂一只椭圆形小鼓，双手各持一根鼓槌，鼓槌上扎有红绸，边打边舞，节奏强烈，舞步多变化，能走出各种复杂美妙的图案。腰鼓舞视频教程可以参考：【广场舞《开门红》欢快喜庆腰鼓舞，正背面演示】 https://b23.tv/5RzBjtA
这里分享全国第二套健身腰鼓中的开场引子步，共十拍，先看完整示范。
分解动作要点
第一拍：左脚向左迈出，同时双手面前交叉打两边鼓，马步蹬。
第二拍：两脚原地跳，两手同时打两边鼓。
第三拍：重心向左形成左弓右箭，同时左手甩绸右手打鼓。
第四拍：重心向右，形成右弓左箭，同时左手收回，右手甩绸。
第五拍：左脚向后撤，形成前弓后箭。同时右手打右鼓面。左手向前甩绸，头向后。
第六步：弓箭步不动，左手收回鼓面，右手向前甩绸，同时头转向前边。
第七、八拍：右脚收回，右手同时打右面鼓，下蹲向前跑。
第九、十拍：左脚踏于右脚尖，同时立起，左手向前甩绸，右手打鼓。
扇子舞
扇子舞的美，在于道具与动作的完美配合。扇子的基本拿法是用大拇指、食指和中指三个手指捏住扇尾撑开扇子，可用大鱼际托住扇骨，固定扇子，无名指和小指可以翘起。
在舞蹈过程中，扇子打开方式有：
竖直打扇：右手拿扇子，捏住扇骨，依靠扇子自身重力打开扇子，扇子竖直放在胸前或头顶；当扇子在头顶打开时，右手应经身体前、侧向上划圆上到头顶打开，扇子略向后拉，右肩膀打开。
水平打扇：右手拿扇子，经身体前、侧拉到五位手位置，大拇指固定扇骨，食指和中指推开扇子，扇子水平打开，扇头朝下，放在身侧。
内8字绕扇：用三个手指勾住扇柄，大拇指和食指分别放在扇子的两边，大拇指和食指用来导向，让扇子朝着你的意愿旋转。

注意事项
如何挑选教程
广场舞的学习，在没有老师的指导下，肯定最先考虑的就是要从网上找相关的教程，这方面的资源应该说是比较多的，尤其是视频资源，可供选择的有很多。但是一定要从中挑选一些适合自己跳的舞蹈来学，对照教程进行分解练习。一般可以下载的视频网站有抖音、优酷、B站视频等等。
如何对照练习
对着教程，我们把视频中的舞蹈分为多个步骤来学，比如24步。一般情况下差不多每8步为一个连贯动作，所以24步也就是3个连续的动作，这样一来我们就把24步分成了3部分，然后再仔细观察3部分中的每一部分中的重复动作，脚部的走位，和手部的动作，找出运动规律。
先练下盘动作
正所谓牵一发而动全身， 人的大部分动作会跟随下身运动，所以只要我们先练习好下身的动作，再练习上身就会变得很快，因此，学习时可以先学步伐，熟练的掌握正确的走位，然后再学习上身的动作，可以起到事半功倍的效果。
循序渐进练习
广场舞的一个特点就是动作流畅，顺其自然。刚开始不要过于追求准确，根据下身运动规律带动上身运动，等基本掌握动作要领后再在准确上下功夫。连贯练习也要遵循循序渐进的方法，把前面分解训练的各部分逐步组合在一起进行练习， 然后再将整个动作结合起来练习。
