Safe construction in coal mines has been the primary principle pursued by mining units for many years. When you purchase a submersible pump, do you know how to use it safely? Let me tell you below.
Before installation and use, the user should carefully check whether the appearance of the electric pump is intact and whether the connections are loose, whether the oil leakage cables are bumped or scratched. And carefully check the flow, lift, voltage, etc. stated on the nameplate for correct use.
.Use a megohmmeter to measure the cold insulation resistance of the electric pump. It should be greater than ohms and lower than ohms. It should be dehumidified before use
. The electric pump should be equipped with a corresponding electric switch and reliable grounding
The green and white ones are ground wires>
. If the cables provided with the electric pump are not long enough, the diameter of the connected cables must be
times that of the original water pump cables, and the connectors must be firmly connected and the number of wires should be reduced as much as possible. The joints and the joints must not be submerged in water
. Check whether it is normal during startup (dry operation does not exceed seconds) and whether the steering direction is correct (the direction is marked on the pump cover). If the steering direction of the three-phase electric pump is incorrect, just replace any two main lines
/> .The electric pump should be stringed with a rope on the handle or lifting eye hole for lifting and standby. It is strictly forbidden to use cables to lift and lift the water pump.
Secondly, do you know about model selection? There are two things you need to tell us when you purchase a BQ submersible pump. So that we can conveniently select the model for you
. Be sure to determine the required flow head and power first
. If you need to confirm, are there any special requirements for the use environment? For example, the value of medium-heavy water in sewage, the water temperature can be up to What kind of installation method should be used?
