Abstract
This thesis introduces a kind of horizontal wet electric submersible pump unit with both submersible and nonsubmersible operational models which can be installed permanently. Then, it analyses the structural features, operating principles, main component performance and rotor system. A series of technical advantages show that this kind of submersible pump has a bright application prospect in conventional drainage and disaster-resistant emergency drainage of deep mines.
Highlights
According to the two hundred and seventy-third regulation of the new edition of Coal Mine Safety Regulations, when the hydro geological conditions are complicated or the mine is at a risk of having water flooded wells, the water proof gate should be set around the shaft station or the other independent power supply system should be installed for implementing the basis of normal drainage around the bottom, where the drainage capacity is not less than the maximum yield of submersible pump [1]
This dissertation introduces a horizontal installation of Amphibious Disaster-resistant submersible pump which can drain off water in mine like a normal pump, but can be used as a submersible pump to support disaster and disaster relief drainage in the mine
Amphibious Disaster-Resistant Submersible Pump with Dual Pump and Dual Motor The Open Mechanical Engineering Journal, 2014, Volume 8 337 on the rotor system includes: (1) The radial force, including the additional radial force on the impeller rotation due to the uneven distribution of pressure along the outer edge of the impeller, the centrifugal force resulting from the residual unbalance weight when the rotor system is rotating and the radial force produced by the weight of the overall rotor system
Summary
According to the two hundred and seventy-third regulation of the new edition of Coal Mine Safety Regulations, when the hydro geological conditions are complicated or the mine is at a risk of having water flooded wells, the water proof gate should be set around the shaft station or the other independent power supply system should be installed for implementing the basis of normal drainage around the bottom, where the drainage capacity is not less than the maximum yield of submersible pump [1]. These traditional submersible pumps used to resist disaster at the bottom for years require setting of the water at the bottom in a way which increases the quantity of mines and the difficulty of installment.
