美国帕利斯防震管
无填料振减振器模型VAF系统设计用于安装在吸气和制冷和空调排放管道,以打击管道传输的空气压缩机系统,通过诱导振动。
Packless VAF's are constructed of deep pitch corrugated tubing for increased flexibility and vibration absorption, covered by high tensile wire braid for superior strength.无填料VAF的深部构造波纹管间距超高强度增加灵活性和编织振动吸收,线材拉伸覆盖高。 Tubing and braid are reinforced by ferrules at each end, and connected to female copper tube ends by high temperature braze alloys.油管和套管加固编织是在每年年底,并连接到女性铜合金管两端高温钎焊。 The units are designed for making sweat connections to refrigerant piping.这些单位设计制作汗水制冷剂管道连接。 Sixteen models are available to fit copper tubing sizes from 1/4 through 4-1/8 inches OD
16个型号可供选择以适合铜管英寸大小从1 / 4到4-1/8外径
Each VAF is pressure tested then carefully vacuum tested using a highly sensitive helium mass spectrometer leak detection device.每个VAF是压力测试,然后小心真空测试使用一个高度敏感的氦质谱检漏装置。 Units are cleaned, dehydrated and sealed in plastic film after final installation.单位被清洗,脱水,塑料薄膜密封后,后安装。 VAF's are available either in bulk or individually boxed. VAF的可大量或个别盒装。
Packless VAF's are recognized under the component programs of Underwriter's Laboratories, Inc.无填料VAF的实验室确认下,公司的组成方案的承销商的 (UL) and the Canadian Standards Association (CSA) for application on both suction and discharge lines in sizes through 3-1/8 inches OD, and for suction side only in sizes 3-5/8 and 4-1/8 inches OD (UL)和加拿大标准协会(CSA)的大小的应用上都吸线和放电通过3-1/8英寸外径,和吸力侧仅在大小3-5/8和4-1/8英寸外径
INSTALLATION安装
Packless VAF's function best when installed as close to the compressor as possible, and perpendicular to the major vibration direction as shown below.无填料VAF的功能安装,尽可能接近的压缩机,并垂直于如下所示的主要振动方向。
For optimum absorption of vibration, the refrigerant line should be anchored at the end of the VAF furthest from the vibration source.对于振动的吸收,冷媒线应固定在振动源端的远的VAF。
Install Packless VAF's horizontally, as shown above, wherever possible.安装无填料VAF的水平,如上所示,尽可能。 Care should be taken to allow sufficient space for the VAF so that it will not be subject to static compression or tension after soldering in place.应当注意让VAF足够的空间,以便它不会受到静态压缩
或地方焊接后的紧张局势。 Units should be installed in a straight line; they are not intended to compensate for offset piping.单位应安装在一条直线上,他们是不是为了弥补抵消管道。
Although high temperature alloys are used to braze the joints of Packless VAF's, the torch flame should nevertheless be directed away from the ferrule when making the sweat connection of the VAF to the piping.虽然高温钎焊合金用于管道的接头无填料VAF的,火炬火焰仍应被指向远离套圈汗水连接时,该VAF。
