不容忽视的管道泵安装的一些细节注意点选用适合扬程的管道泵一般认为管道泵扬程小，则消耗功率小。但在实际上消耗功率是管道泵的流量成正比的，扬程小，则流量会增大，消耗功率也就随之增大。当高扬程用以低扬程抽水时，电机会因过载而发热甚至会烧毁电机。注意点管道泵进水口的深度适宜管道泵进水口入水太深极易造成吸入水池地步沉积杂物导致阻塞，进水口与水池底部距离应大于进水口直径的1.5倍；若进水口入水太浅，会产生漩涡，影响进水，适宜深度为6~1mm。

为什么原装的制冷压缩机不保修？这个问题其实问得很好，产品不是有三包的吗？不保修那里行呀。为什么还要卖得贵而保修的还要卖得便宜？1。原装机的生产成本不可能与市面的二手货，翻新，下线机相比2。在操作制冷维修的基本都是电工，机修工等，常有部份人员经验技术根本不过关，也没有几个真正的得到持证上岗，那怕持证也有部份没维修经验。制冷系统基本分析以下4项缺一不可：A高低压力（压缩比）B冷煤充注量C运转电流D压缩机过热度/以上4项有1项偏差过量，必造成压缩机损耗。
