【摘要】：化工流程泵是在石化行业内广泛应用的传输设备，机械密封作为化工泵的重要配件，起到了提高机器效率、降低能耗，减少机器的泄漏，提高机器容积效率作用，达到节约能源、保护环境目的。很多化工泵工作条件苛刻，工作环境经常发生变化，这就要求泵的机械密封能够适应这些工作环境，如何评价提高机械密封产品的性能和使用寿命，降低由于机械密封失效所带来的损失，是研发变工况机械密封试验台主要目的。论文研究变工况化工泵机械密封实验台是一套模拟机械密封工作状况的实验设备，能够模拟密封各种变工况工作情况。根据具体实验要求，变工况机械密封实验台测试系统具有测量温度、压力、转矩、转速、泄漏量等工作参数的能力。其相应试验控制软件系统应该具有数据储存和处理能力，装置能够模拟机械密封变工况工作，使用变工况试验台对机械密封进行自动试验，并收集记录试验数据。
[Abstract]:Chemical process pump is a widely used transport equipment in petrochemical industry. As an important part of chemical pump, mechanical seal can improve machine efficiency, reduce energy consumption, reduce machine leakage and improve machine volume efficiency. To save energy and protect the environment. Many chemical pumps have harsh working conditions and changing working environment, which requires that the mechanical seals of the pumps be able to adapt to these working conditions. How to evaluate how to improve the performance and service life of mechanical seal products, Reducing the loss caused by mechanical seal failure is the main purpose of developing a mechanical seal test rig. In this paper, the experimental bench of mechanical seal of chemical pump under different working conditions is studied. It is a set of experimental equipment to simulate the working condition of mechanical seal. The test system of mechanical seal under different working conditions has the ability to measure working parameters such as temperature, pressure, torque, speed, leakage and so on. The corresponding test control software system should have the ability of data storage and processing, and the device can simulate the off-condition operation of the mechanical seal, and use the off-condition test bench to carry out the automatic test of the mechanical seal, and collect and record the test data.
