It should be noted that pump signs marked on the head and the use of water lift there is a difference, this is because of water through aqueducts and pipes must be near the resistance loss.

必須注意，水泵標(biāo)牌上注明的揚(yáng)程與使用時(shí)的出水揚(yáng)程是有差別的91精品啪在线观看国产蜜臀，這是由于水流通過輸水管和管路附近時(shí)會(huì)有一定的阻力損失中文字幕日韩精品人妻在线视频。

The biggest characteristic of this model is that the hydraulic system pump station, operating console and working clamp installation table can be installed and connected in users sites and dived the test workpiece into the pond, can lift up and down, left and right two directions clamp worktables set 90 degree overturn function, especially suitable for gas pressure test.
