Bete喷雾实验室

喷嘴设计,分析和测试


Bete的喷雾实验室工程师在过程中研究和分析喷雾及其行为。我们测量常见的喷雾特性,包括流速和压力,液体分布,液滴尺寸和液滴速度。我们还可以建立您的过程的物理模型,以帮助诊断问题或选择最佳喷嘴。

Indoor Spray Area


  • 50'x 30'x 22'高(15 m x 9 m x 6.5 m高)
  • Water recirculates from a 4,500-gallon (17 m^3) reservoir.
  • 防水混凝土、金属墙和防水light fixtures allow us to test large experiments, like far-reaching tank cleaning nozzles.
  • Nozzles and fixtures are on a remote-controlled hydraulic boom for height adjustment.
  • XY Traverser携带其他专业仪器,例如模式器。
  • Can also be used to set up special piping or models such as the one shown here.

Outdoor Spray Area


  • 实验室附近有足够的户外空间进行测试,需要广阔的区域。
    • 示例:测试风漂移或防火喷嘴的到达。

Pumping Capacity


  • Allows for 1,800 gal/min (7,000 L/min) at low to moderate pressures and can pump up to 40 gal/min @ 1,740 psi (150 L/min @ 120 bar).
  • Shop air is available at up to 100 psi and 600 SCFM (7 bar and 1,000 Nm3/h).
  • 对于更广泛的水或空气流,我们使用租赁设备。我们已经进行了7,000 GPM(25,000 L/分钟)的水和3,000 SCFM(5,000 nm3/h)空气的测试。

数据获取和控制


A data acquisition system links instruments with our control elements for automatic control of test conditions and data recording. In-house programming provides rapid flexibility to accommodate diverse test setups.

标准仪器包括电子压力传感器和磁性,科里奥利和涡轮流量计。

我们根据需要与其他仪器合作。例如,应变计评估压力成分或长矛振动中的应力,而热电偶在生命周期测试中监测温度。


Alternative Fluid Testing with Analogs


虽然我们通常与水一起工作,但我们可以使用无毒的无害液体进行测试。如果液体特别有害或昂贵,我们可能会使用具有相似特性的类似物。例如,甘油是模拟液体比水更具粘性的一种选择。

在10英尺x 8英尺x 8英尺(3 m x 2.5 m x 3 m)的固定室中,用水以外的液体喷洒。该室具有天花板和观看窗户。它配备了250加仑(950升)地板上不锈钢罐,以完全含有液体。通过消除雾气排气可将液体喷出一般区域。


专门测量


Analysis of sprays involves some unique instruments. If your problem requires a special evaluation technique, we can work with you to develop one tailored to your application. For example, a customer interested in coating bottles needed a way to determine if the sprayed coating was reaching the areas between bottles on a conveyor belt. We treated the bottles with a moisture-revealing coating that would show areas wetted by the mist. We've evaluated tank cleaning effectiveness by coating stainless steel panels with relevant contaminants and measuring the mass loss of contaminants with various sprays at various distances.

High-speed photography may be used for applications such as visualization of particle flow in a fluidized bed or to measure the speed of unatomized fluid structures.
