14、11 22 14 36 - 3 Refer to Section 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 i
15、ndoors / Nema 4X enclosure for 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.
16、 The level control system will 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, o
17、r bell. The alarm shall have a 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 c
18、ontrol mechanism b. HOA switches 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 eac
19、h pump g. automatic motor overload protection 2. For a duplex system, provide an alternating relay to automatically alternate leadoff and standby duties of each pump of a duplex unit at the end of each pumping cycle. Standby pump shall start when water level in sump rises to a predetermined level th
20、at indicates excessive inflow or failure of the lead pump. 3. 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 as recommended by pump manufacturer to pr
21、otect short cycling. Sensors shall be located to activate the alarm adequately before the water level rises to the inlet pipe. 4. 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 it
22、s own breaker so that if a pump Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-01-11 22 14 36 - 4 overload trips a breaker, the alarm system will still function. Each power supply is to be wired in its own conduit. 5. Wiring from the sump to the con
23、trol panel shall have separate conduits for the pump power and 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, fiberglass or high density polyethylen
24、e basin with gas tight covers. Cover shall be sized so as to inspect and maintain pump installation manhole 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.
25、 Provide a union, check and ball valve in the discharge of each pump where indicated on drawings. J. Removal/Disconnect System: Where indicated on drawings, a removal/ disconnect system shall be provided. The system will consist of a discharge fitting mounted on a vertical guide rails attached to th
26、e sump. The pump shall 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 rem
27、ove the pump. Where the 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 wit
28、hout disconnecting the 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 equip
29、ment shall be performed simultaneously with the system of which each item is an integral part. B. System Test: After installation is completed provide an operational test of the completed system including flow rates, pressure compliance, alarms and all control functions. C. When any defects are dete
30、cted, correct defects and repeat test. D. The commissioning Agent will observe startup and contractor testing of selected equipment. Coordinate the startup and contractor testing Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-01-11 22 14 36 - 5 sche
