One, pump of phreatic water report
Pump of phreatic water reportIt is product of Electromechanical unifinication high-tech. In recent years, as a result ofSumbersible pumpThere was great progress in the technology such as sealed, insulation, refrigeration and monitoring, realized water pump and the automatic coincidence of conduit giving water successfully at the same time, make large requirements dives electric pump popularizes applied rate to be accelerated apparently thereby. Because pumping station of phreatic water cable is in economic project investment, can install the overhaul, moving condition to be improved greatly quickly, the dependability of equipment and service life rise significantly. At present our country is produced not only and installed the axial-flow pump under large requirements 900mm and mixed flow pump, also can produce the pump of large dive report of caliber 1.4m and 1.6m, laid good foundation to dive the technology of electric pumping station is popularized. Pump of phreatic water report is not afraid that water wides, have the advantage with be demolished as good as the maneuverability such as installation quickly again, can deal with water level rocket, pump room to flood wait for all sorts of sudden incident, of pump of large dive report come out, make means of type of pumping station structure, installation, moving environment produced revolutionary change. Compare with photograph of groovy pumping station, the advantage that dives electric pumping station is in low-lying easy waterlogged area is more clear. In the meantime, still have pump of phreatic water blowdown and platoon sand a variety of pump such as pump, can keep clear of in time catchment wadi deposit. 

(One) the characteristic of pump of phreatic water report

1. pumping station is not afraid that water wides

To low-lying easy waterlogged area, in dike when burst or the especially big rainstorm that design a standard more than come, pumping station of irrigation and drainage often is wided by water. Once the Electromechanical equipment of pumping station is immersed by water, clean and roast wait for repair workload very big, will defer catchment time, increase calamity loss. Accordingly, the prevent or control flood of itself of groovy pumping station is moistureproof the problem also is one of very serious problems. But what pump of phreatic water report uses is phreatic water electric machinery, water pump aircrew can move in underwater. So, although pumping station is flooded by water, want electric machinery not to overload only, water pump can dive in stable division job electric pump can be thrown at any time move. 

2. aircrew is torn open install quick 

Before sumbersible pump and giving conduit is to use bolt connection, basically use at deep well to carry catchment of water, small-sized construction to wait. But pump of latter-day phreatic water report and piece automatic coincidence had come true between conduit, below the case that gives conduit to secure, need bolt can be installed quickly and do not disassemble water pump aircrew, accelerated the installation of aircrew and overhaul rate greatly thereby. If Heibei saves the Xie San of dark blue city to assign pumping station, the aircrew of axial-flow pump of caliber 1.4m vertical of every convention installs time to be 15 ～ 20 days, and the pump of phreatic water report with same caliber needs 1 day only. To aircrew of pump of small-sized dive report, installation disassembles more convenient, some needs 1 hour to be able to be installed or disassemble only end. It is very advantageous that this tears open the pumping station of outfit urgently closely to the need such as drain flooded fields of prevent or control flood. 
