摘要:
为了在实际生产中提高双列同向螺旋槽密封效果,分析了其机械密封端面的液膜流场分布。基于计算流体力学(CFD)软件对所建立的双列同向螺旋槽机械密封端面和普通接触式机械密封端面结构的三维模型进行了数值模拟分析。针对各种工况模拟液膜在动环端面上的流场状态,计算模型的泄漏量。利用实验设备测量实际工作中液膜的压力分布与泄漏量。将普通接触式机械密封端面实验数据与其模拟结果进行对比,两者之间存在误差的主要原因是实验过程中设备的振动。模拟结果显示在0.1~0.5 MPa范围内相同转速的工况下,双列同向螺旋槽结构的密封效果约
Abstract:
To improve the seal property of corotating double spiral grooves in practical operation,the flow field of the liquid film of the mechanical seal is analyzed.The three-dimensional models of the mechanical seals of a corotating double spiral groove and a normal contact are numerically simulated using a computational fluid dynamics(CFD)software.The flow field states of the liquid film on the rotating seal ring are simulated for various working conditions,and the leakage is calculated.The pressure distribution and leakage of the liquid film are measured using professional equipments.The simulation data of a normal contact seal is compared with its experimental data,and the main reason for the error is the vibration of the equipment during the experiment.The simulation results prove that the seal ability of the corotating double spiral groove is approximately two times as the normal contact seal with a same speed and within the limit of 0.1-0.5 MPa.
