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, whether the connections are loose, oil leakage, and whether the cables are scratched. And carefully check the flow rate, head, 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. If it is lower than ohms, it should be dehumidified. It can be used only after passing the test.
. The electric pump should be equipped with a corresponding electric switch and be reliable. Grounding,
. If the cable provided with the electric pump is not long enough, the diameter of the connected cable must be
times that of the original water pump cable, and the connector must be Securely, and reduce the number of wire joints as much as possible, and the joints must not be submerged in water
. Check whether it is normal during startup (dry operation does not exceed seconds), whether the steering direction is correct (the direction is marked on the pump cover), and whether the three-phase electric pump turns No, just swap any two main wires
. The electric pump should be stringed with a rope on the handle or eyelet hole for lifting and setting up. It is strictly forbidden to use cables to lift, place, lift or pull the water pump.
&Secondly, do you know about model selection? When you purchase a B submersible pump, there are two things you need to tell us. So that we can easily select the model for you
.&Be sure to determine the required flow rate, lift and power first,
.&If you need to confirm, are there any special requirements for the use environment, such as the weight of the medium in sewage, water value, the highest water temperature can reach, and what kind of installation method should be used.
Of course, if you are an old customer of coal mine supply, you only need to tell us the model and voltage you need.
Our factory specializes in creating various models of B submersible pumps with high quality and low price for you. They have coal safety and other certificates. If you are an old manufacturer, please feel free to buy
