水泵理论最大吸程为9,8米但是实际上最好的离心水泵吸程也就是6米左右。一般三层楼的高度在9米左右一般离心水泵基本上是不可用的。建议你选用柱塞水泵（也就是活塞泵），这种泵的吸程较高、较容易满足你的使用要求。但是无论使用哪一种水泵都是要求在开泵以前要将水泵和管道内充满水。在使用的时候比较麻烦。建议你能在一楼或者三楼安装离心水泵(管道泵）增压。

锁具

的选择要注意以下三点：

的灵敏程度。（4）尽量购买品牌知名度高的锁具，保证质量，经久耐用。 　 另外，请注意买来的新锁中有一个不起眼的金属开锁片，千万不要小看它。如果遇上钥匙丢失或锁具故障，用开锁片可以轻易将锁具拆下，进行更换。可将开锁片拆下无钥匙的一端，取下把手，再抽出带钥匙的另一端，装上新锁，不会损坏其它部位

六、如何选购家用烤箱？

展开全部

选择家庭烤箱怎么样才能选到合适的呢？需要注意哪些点呢？

是否合适就看个人的需求点，买家庭烤箱需要注意的点，只要这2方面结合起来考虑就好了。至于推荐，我家用的是CASDON的

一、烤箱容量

容量太小满足不了大家庭的烘焙需求，小容量的烤箱容易导致食物表面被烤焦，容量太小的烤箱一般不能烘焙受热膨胀的食物。

二、加热模式

加热模式越多，能烘焙的食物就越多，对烘焙要求高的家庭，就越能得到满足。比如全方位风烤，上下双向炙烤，热风循环烤，解冻和旋转烤架风烤等。

三、控温方式

对于几百块钱的小容量烤箱，是独立控温的，但是它的缺陷也非常大，对于台式大容量烤箱和嵌入式烤箱，控温方式是上下管统一控温。很多优质烤箱为了让腔体温度更饱和，是上下加热系统，背部烧烤金属和背部对流风扇组成。

四、散热系统

散热系统涉及到机器的寿命，橱柜甚至是人生财产的安全，所以是必须参考的重点，大部分烤箱是前置散热的，冷风从底部进入腔体，然后从顶部排出，形成一个闭环，有效过滤浑浊空气，排出洁净清新气体。

六、内腔材质

前面说了，纯烤箱的内胆材质一般是高端搪瓷内胆，其坚固耐用，耐腐蚀、高温，表面紧密光滑，免除清洗烦恼。

七、门板材质

台式烤箱一般是2层玻璃门板，嵌入式烤箱则是3层钢化玻璃，可以有效的阻断热量流失，提高热能利用效率，节能省电，隔热效果显著。

八、清理

内腔清理难易程度，跟内腔材质有关，也与烤箱密封程度有关，烤箱一般是搪瓷钢板材质，烤箱门缝密封可拆卸的话，可以清理卫生死角。

九、面板智能触控

简单明了的操作面板，烘焙菜鸟也能玩转；智能开启智烤新时代，一键就可让你做甩手大厨。

八、省电

节能调频，节省烹饪上的时间成本，也能省电省成本。

七、家用加湿器选购技巧？

说到加湿器的选购，那可不能光凭价格的高低，来判断合适与否。还需要对加湿器的音量、适用面积等情况有一个全方位的了解和比对才行。要不然一旦买回来不合适，退换也挺麻烦的。

一，了解工作音量的大小

音量的大小，一般都是由分贝值来衡量的。若分贝值很高，则表明该加湿器的噪音越严重。反之，便说明加湿器在工作时噪音很小。

我们常见的加湿器呢，它们的分贝值大体上在40至70之间。所以，大家在实际选购时，应选择分贝值尽可能低的，这样即便是在夜晚加湿使用，也不易影响到自己和家人的休息。

二，注意适用面积

选购加湿器时，还应了解清楚它的适用面积。像一些储水量低于250ml的加湿器，如果将其放在空间比较大的主卧，那用不了多长时间，就得麻烦我们重新去添水了。因此，在选购加湿器时，应特地注意这一点，不然的话，频繁的加水也挺费时费力的。

三，是否带有亮丽的照明灯

加湿器如果自带照明系统的话，我们在夜晚按键操作时会很容易。若没有该功能，那大家调控加湿器开关或档位时，就显得十分的不便。所以，如果价格方面还算合理，建议各位选择带有照明灯的那种加湿器。

四， 看档位是否多样

长时间应用单一的速度去加湿，可能会让大家感觉不太舒服。鉴于此，大家在选择的时候尽可能选择档位多的那一款加湿器。市面上的多档位加湿器一般有：两档、三档、四档几种，各位在选购时应首先考虑四档或三档的。这样我们就能根据身体实际情况，来灵活调整加湿速度了。

八、如何选购家用钢琴？

1、首先必须到正规琴行或正规生产企业的销售门市购买。 而且要选择规模较大、产品质量和服务质量较好的知名企业的产品。注意：产品标识应完整、齐全。有商标及规格型号、说明书、合格证、检验员、出厂日期、保修卡，以及生产企业名称、地址等。 （尽量购买本地产品，不仅可避免因气侯差异对钢琴造成的影响，而且价格相对便宜，产品的售后服务也较便利。）

2、钢琴音色很重要。首先中音区要好，要连贯一致; 次低音区音色要纯正、洪亮，有穿透性，震撼力强，有钟鸣的效果；两端的音是考核钢琴的设计水平，设计水平越高，两端的音色越好。

3、一架精美的钢琴，不仅有演奏的功能，而且放于室内还有较强的装饰性。所以，挑选钢琴时，还应留意产品的外观质量如何。比如，您可察看一下琴壳的油漆是否光滑、平整、明亮，色泽是否均匀，以及钢琴板面有无开裂及划痕等。 键盘平整、缝隙均匀，琴键负荷不可太重，以免造成小孩手指的损伤。

4、钢琴是相对价格较昂贵的耐用消费品，但无论是劣质钢琴还是优质钢琴，刚出厂时从外表到音质和手感都不会有明显的差别（对非专业人员来说），但在一、两年后就会有明显的差别，严重的会出现琴键变形、松动，弹奏困难；音质、手感变差；击弦机零件松动，杂音不断出现；弦轴松动，需要经常调音；音板开裂等现象。

九、家用制氧机怎么选购？

怎么选制氧机？

制氧浓度，对此，国内有明确规定，医用分子筛制氧设备的氧浓度要达到90%以上，一些大品牌的医用级5L制氧机就能稳定供氧93%±3，这种就是符合国家医用标准的。

2.使用体感，比如，制氧机运行时噪音到底有多大？会不会影响睡眠等？一些大牌的制氧机运行分贝控制在40-50之间，这个范围就是相对轻音的了。如果是睡眠质量本来就不太好的人就可以优先考虑这个。

3.认准品牌，不论标注的参数如何，认准三证合一、有自主生产能力的品牌都非常重要，只有产品的商标许可证、产品注册证、生产许可证一致，产品的品质才更有保障。此外，制氧机作为医疗机械，我们肯定要考虑到它的售后，完善的售后维修、保养服务能解决很多后顾之忧。

十、家用浴缸选购方法？

1、浴缸的大小选择要根据澡堂的尺寸来确认。

2、相同体积大小的浴缸，其深度、宽度、长度有一变量不同，其他变量也不相同，同时废物出口也会设置不同。例如选择水深点的浴缸，废物出口的方位相对要高一些。

3、购买单面有裙边的浴缸，购买的一定要注意下水口、墙面的方位与裙边的方向一致，避免买错产品。

4、如果浴缸上要加淋浴喷头的话，浴缸尽量要挑选稍宽一点的，淋浴方位下面的浴缸部分要平坦，且应经过防滑处理。
