Materials of construction shall be suitable for their applica-tion from the standpoints of corrosion resistance and mechanical performance.4.6.2 Design. The motor shall be of the squ

34、irrel-cage induction type,suitable for across-the-line starting and shall be capable of reduced-voltage starting. Ifspecified by the purchaser, the motor shall be capable of reduced-voltage-stopping oroperation using a variable frequency drive. The motor shall be capable of continuousoperation under

35、 water at the conditions specified by the purchaser.4.6.3 Temperature. The motor temperature shall be rated no higher than theallowable operating temperature of the motor thrust and radial bearings and in noFigure 1 Typical submersible-pump assembly (bowl assemblies)12 AWWA E102-06case shall it exce

36、ed the temperature rating of the insulation class used to wind themotor.4.6.4 Thrust bearing. A thrust bearing of ample capacity to carry the weightof rotating parts, plus the hydraulic thrust at maximum operating head, shall be anintegral part of the motor. For antifriction bearings, the bearing sh

37、all be of suchcapacity that the AFBMA calculated rating life (L10) shall be no less than 8,800 hr.If the design and operating conditions are such that upthrust can occur, properprovisions by the manufacturer shall be made to accommodate the upthrust. Thethrust bearing shall also have ample bearing c

Sustained operation of a submersible pump against a closed valve is notadvised because of possible damage to the motor or other connecting appurtenances.4.6.5 Seals. Seal types shall be pressure-balanced single or double mechanicalsea

41、ls. Mercury-type seals shall not be permitted, unless specified by the purchaser.4.6.6 Foreign matter. Suitable precautions shall be taken to restrict sand, silt,or other foreign matter from entering the motor.4.6.7 Pump size. The maximum motor diameter and the minimum insidediameter of the well sha

42、ll be in such relationship that under any operating conditionthe water velocity past the motor shall not exceed 10 ft/sec (3.0 m/sec) nor be less than1.0 ft/sec (0.3 m/sec). For this purpose a minor irregularity in the motor shape, such asthat caused by the cable connection, shall not be included in

43、 the motor-diametermeasurement. For flow velocity conditions other than those recommended above, ashroud may be recommended by the manufacturer. The supplier shall verify motorshroud requirements based on operating flow characteristics provided by the purchaser.Sec. 4.7 Submersible Cable4.7.1 Conduc

44、tors. The cable shall consist of three or more separate conduc-tors, including a ground cable or a single-cable assembly with three or moreconductors, including one for a ground. Stranding shall meet ASTM classdesignation standards: Class B on No. 10 and smaller cable and No. 1 through4/0 cable; Cla

45、ss C on No. 9 through No. 2 cable. Each conductor shall be insulatedby synthetic rubber or plastic insulation suitable for continuous immersion in water.When three or more single conductors are used, each shall be jacketed. The jacketmaterial shall be oil- and water-resistant synthetic rubber, metal

46、, or other suitablemechanically protective material. The cable shall have a sufficient conductor area tomeet the minimum requirement of the ICEA code for operation in air. Theconnecting electrical cable from the starting equipment to the surface plate shall meetthe National Electrical Code or local

47、codes, whichever govern.4.7.2 Supports. The cable shall be suitably supported from the column atseveral points adequate for the type of cable used with corrosion-resistant clamps.4.7.3 Fittings. Cable fittings and terminals shall be watertight at the pressureencountered in use.4.7.4 Lengths. For eac

48、h 50 ft (15 m) of setting, 1 ft (0.3 m) of extra cableshall be allowed to compensate for possible twist or sag of the cable duringinstallation; 10 ft (3 m) shall be provided beyond the surface plate, unless otherwisespecified by the purchaser.14 AWWA E102-064.7.5 Mechanical shielding. The electrical

49、 conductors shall be protected by acorrosion-resistant cable guard where they pass the pump bowls.Sec. 4.8 Surface PlateThe surface plate (pump base) shall support the entire weight of the suspendedparts when filled with water. The plate shall provide suitable openings for the powercable, well vent, and water-level indicator as required. The plate shall provide asupport for the power cable as required by the electrical code. The plate shall alsosupport the discharge connection provided in a size adequate for the required flowrate and in a pressure series consistent with
