[Asia Pump Network News] Introduction pump products, the installation is often involved in a small series of issues, we can see its importance. Today, Xiaobian to introduce the QJ-type well with the submersible pump before installation inspection and preparation, although the preparatory work before installation, but still can not be ignored, it is a smooth installation of a guarantee. Now, let's look at QJ type well submersible pump installed before doing what. QJ-type submersible pump with pre-installation inspection and preparation (1) Check whether the well meets the pump conditions of use, that is, borehole diameter, vertical and wall quality, as well as static water level, water level, water inflow and water quality conditions. If you do not meet the conditions of use must take appropriate measures, or can not pump down. (2) Check the power supply equipment and power supply circuit can ensure the normal operation of the pump. (3) Whether the power voltage and frequency meet the conditions of use. (4) according to the packing unit to check whether the parts are safe and familiar with the installation instructions. (5) Check the electrical lines, control and protection device is reasonable and safe. (6) equipped with a variety of installation and use tools, erect tripod and hanging chain (or other lifting tools) to be safe, reliable and easy to use.
