9、id Controls Institute, Inc. to provide manufacturers, users and specifiers of the products with uniform methods and requirements to conduct performance testing of secondary pressure drainers. The standard was developed by a technical subcommittee of the Secondary Pressure Drainer Section. The subcom

10、mittee completed its work in late 1999 and the standard was submitted to the section for approval as an FCI standard and was approved May 22, 2000. The standard was approved as an American National Standard in 2014. FCI recognizes the need to periodically review and update this standard. Suggestions

11、 for improvement should be forwarded to the Fluid Controls Institute, Inc., 1300 Sumner Avenue, Cleveland, Ohio, 44115-2851. All constructive suggestions for expansion and revision of this standard are welcome. The existence of a Fluid Controls Institute (FCI) standard does not in any respect preclu

12、de any member or non-member from manufacturing or selling products not conforming to this standard nor is the FCI responsible for its use. While the recommendations for performance testing and evaluation herein are technically sound, it is not intended that they be considered the only method for tes

13、ting and evaluation. These recommendations should not be interpreted as superior to or a standard that would necessarily be preferred in lieu of an engineers design for a particular system. These recommendations for performance testing and evaluation originate from the collective experience of leadi

16、iners 1.0 SCOPE 1.1 This standard specifies performance tests that are considered to be applicable to secondary pressure drainers. 1.2 These tests may be conducted to evaluate the performance of a particular design, either currently in production or under consideration for production. 2.0 DEFINITION

17、S 2.1 Secondary Pressure Drainer (SPD)- A vessel which collects and discharges liquid by alternately pressurizing and depressurizing through a given valve arrangement, utilizing a secondary, compatible vapor or gas pressure as the motive source. 2.2 Operating Mechanism - Sensing and valving arrangem

18、ent of the SPD that alternately provides and relieves pressure from a secondary motive source in accordance with predetermined fluid levels within the SPD. 2.3 Performance Characteristics Tests - Tests that are carried out to determine the operational and performance characteristics of secondary pre

19、ssure drainers. 3.0 TECHNICAL TERMS 3.1 Maximum Allowable Pressure (PMA)- Maximum pressure to which the SPD can safely be subjected without failure of the pressure boundary members. 3.2 Maximum Operating Pressure (PMO) - Maximum rated motive pressure at which the operating unit will function correct

20、ly. 3.3 Motive Pressure (PM) - Compatible gas or vapor pressure from a secondary source used to discharge the liquid medium from the SPD. 3.3.1 Steam Motive Source - Saturated steam (at the temperature that corresponds to the boiling temperature of water at an existing pressure) used as compatible v

21、apor to discharge liquid from SPD. 3.3.2 Air or Inert Gas Motive Source - Compressed compatible vapor to discharge liquid from SPD. 3.4 Static Fill Head Pressure - Pressure created in vertical column of liquid (Pressure created at a defined point in a column of liquid). 3.4.1 Static Fill Height from

22、 Top of SPD (FHT) - The distance from the top of the SPD to the liquid level. 3.4.2 Static Fill Height from Bottom of SPD (FHB) - The distance from the bottom of the SPD to the liquid level. 3.5 Back Pressure (PB) - Pressure measured at the discharge of the SPD 1under static head (non-flowing) condi

23、tions. 3.6 Hot Condensate Capacity (QH)- Maximum mass of condensate that the SPD can discharge in one (1) hour at a defined set of operating conditions ( i.e. motive type/pressure, back pressure, static fill head, hot condensate temperature as defined in 5.2.1). 3.7 Complete cycle - consists of basi

24、c elements: fill, charge, discharge, vent. 3.8 Cycle time - point to point time interval over consecutive complete cycles. 3.9 Test time - Time to complete test. 4.0 PERFORMANCE PARAMETERS A manufacturer shall describe the performance of the SPD by testing for the following parameters. Further detai

25、ls on appropriate test methods are specified in 5.0. 4.1 Motive Source - SPD shall be tested using saturated steam and/or air/inert gas as the motive source to determine condensate capacity at various sets of defined operating conditions (i.e., motive type/pressure, back pressure, static fill head,

26、hot condensate temperature as defined in 5.2.1). 4.2 Motive Pressure (PM). 4.3 Maximum Operating Pressure (PMO). 4.4 Back Pressure (PB). 4.5 Hot Condensate Capacity (QH). 4.6 Static Fill Head Pressure. 5.0 TEST METHODS FOR PERFORMANCE EVALUATION 5.1 Test Cycle Description - The SPD shall be fed with

27、 hot water from a receiver at the defined static fill head pressure above the SPD. Hot water will flow through the inlet check valve until the sensing or valve arrangement is activated, thus introducing the motive source, charging the SPD. When the liquid has been discharged, the sensing or valve ar

28、rangement is activated to vent and depressurize the SPD so liquid can reenter the vessel. (Refer to Figure 1). 5.2 Atmospheric test - tests shall be conducted with the SPD vent valve connection exposed to atmosphere. 5.2.1 Entering test fluid shall be hot water at or above 190F. The water temperatur

29、e shall be measured with calibrated equipment (i.e. thermocouples) before liquid enters the SPD. Temperature must be maintained for test duration. 5.2.2 Hot water may contain a corrosion inhibitor, or any other suitable liquid that does not have a viscosity greater than that of water. 5.2.3 Motive s

30、ource shall be clearly stated. 5.2.4 Static fill head pressure shall be determined and defined for each set of operating conditions. Constant static fill head pressure must be maintained throughout the range of testing and duration of testing as defined below. 5.2.5 Back pressure shall be determined

31、 and defined for each set of operating conditions. Constant back pressure must 23be maintained throughout the range of testing and duration of testing as defined below. 5.2.6 Motive pressure shall be defined and held constant throughout the range of testing and duration of testing as defined below.

32、5.2.7 Record mass discharge using a density compensated calibrated tank or weight scale. 5.2.8 Minimum test cycles - Minimum number of consecutive complete cycles for flow measurement shall be as follows: Inlet Nominal Pipe Size Minimum Number of Consecutive Complete Cycles Thru 1-1/2” (DN40) 20 2”-

33、3” (DN50-80) 15 4” and larger 3 5.2.9 Record test time. 6.0 PERFORMANCE EVALUATION 6.1 Determination of Maximum Operating Pressure (PMO) The maximum operating pressure of the SPD may be determined by carrying out test cycle as defined by 5.1 while successively increasing the defined test motive pres

34、sure up to the SPD maximum operating pressure not to exceed the PMA. The SPD shall be cycled throughout the process to observe proper function. 6.2 Determination of Capacity The capacity of the SPD shall be determined by 5.2.7 divided by 5.2.9 under specified conditions. Test shall be run at various

35、 operating parameters to determine SPD capacity at each set of conditions.
