Size the motor capacity to operate pump without overloading the motor at any point on the pump curve. Refer to Section

15、 22 05 12, GENERAL MOTOR REQUIREMENTS FOR PLUMBING EQUIPMENT. F. Starting Switch: Manually-operated, tumbler type, as specified in Section 26 29 11, LOW-VOLTAGE MOTOR STARTERS. G. Automatic Control and Level Alarm: Furnish a control panel in a Nema 1 enclosure for indoors or in a Nema 4X enclosure f

16、or outdoors. The controls shall be suitable for operation with the electrical characteristics listed on the Electrical drawings. The control panel shall have a level control system with switches to start and stop pumps automatically, and to activate a high water alarm. The level control system will

17、include sensors in the sump that detect the level of the liquid. The sensors may be float type switches, ultrasonic level sensors, transducers, or other appropriate equipment. The high water alarm shall have a red beacon light at the control panel and a buzzer, horn, or bell. The alarm shall have a

18、silencing switch. Provide auxiliary contacts for remote alarming to the Energy Control Center and BAC net compatible open-protocol type interface to DDC Controls System. 1.The circuitry of the control panel shall include: a. power switch to turn on/off the automatic control mechanism b. HOA switches

19、 to manually override automatic control mechanism c. run lights to indicate when pumps are powered up d. level status lights to indicate when water in sump has reached the predetermined on/off and alarm levels e. magnetic motor contactors f. disconnect/breaker for each pump g. automatic motor overlo

20、ad protection 2. Sensors that detect the level of water in the sump shall be so arranged as to allow the accumulation of enough volume of liquid below the normal on level that the pump will run for a minimum cycle time as recommended by the pump manufacturer. Sensors shall be located to activate the

21、 alarm adequately before the water level rises to the inlet pipe. 3. Provide two separate power supplies to the control panel, one for the control/alarm circuitry and one for power to the pump motors. Each power supply is to be fed from its own breaker so that if a pump overload trips a breaker, the

22、 alarm system will still function. Each power supply is to be wired in its own conduit. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-01-11 22 14 29 - 4 4. Wiring from the sump to the control panel shall have separate conduits for the pump power an

23、d for the sensor switches. All conduits are to be sealed at the basin and at the control panel to prevent the intrusion of moisture and of flammable and/or corrosive gases. H. Sump: Furnish cast iron or fiberglass basin with gas tight covers. Cover shall have 280 mm by 380 mm (11-inch by 15-inch) ma

24、nhole with bolted cover, vent connection, openings for pumps and controls. Sump shall be sized to allow an adequate volume of water to accumulate for a minimum one minute cycle of pump operation. I. Provide a check and ball valve in the discharge of each pump. J. Removal/Disconnect System: In a syst

25、em utilizing a submersible pump, where sump depth, pump size, or other conditions make removal of the pump unusually difficult or unsafe, a removal/disconnect system shall be provided. The system will consist of a discharge fitting mounted on vertical guide rails attached to the sump. The pump shall

26、 be fitted with an adapter fitting that easily connects to/disconnects from the discharge fitting as the pump is raised from or lowered into the sump. The discharge piping will connect to the discharge fitting so that it is not necessary to disconnect any piping in order to remove the pump. Where th

27、e sump depth is greater than five feet or other conditions exist to make the removal of the pump difficult or hazardous, the system shall include a rail guided quick disconnect apparatus to allow the pump to be pulled up out of the sump without workers entering the sump and without disconnecting the

28、 piping. PART 3 - EXECUTION 3.1 STARTUP AND TESTING A. Make tests as recommended by product manufacturer and listed standards and under actual or simulated operating conditions and prove full compliance with design and specified requirements. Tests of the various items of equipment shall be performe

When any defects are detected, correct defects and repeat test. D. The commissioning Agent will observe startup and contractor testing of select

30、ed equipment. Coordinate the startup and contractor testing schedules with the Resident Engineer and Commissioning Agent. Provide a minimum of 7 days prior to notice.
