泵闭公差配合
This presentation focusses on critical close fit tolerances and certain surface finish specifications.
Axial Thrust in Rotodynamic (Centrifugal) 泵
When repairing centrifugal and axial flow pumps, axial thrust is a concern. An understanding of the causes and the mitigating provisions of various pump designs will help repair technicians to ensure those provisions work properly.

New study shows major savings potential with power drive systems on commercial pumps
While adding variable speed capability in commercial buildings is not a new idea, a new analysis confirms major energy and cost savings is available by pairing those products with a power drive system (PDS) – regardless of a pump’s load variability. PDS由电动机组成, adjustable speed controls and sensors that provide feedback to the equipment, allowing the equipment to slow down or speed up to meet current demand. This idea and the added flexibility a PDS can provide may be even more important as we move forward in uncertain times.
Natural Frequency 测试 – Bump Tests and Modal Analysis
Anyone dealing with installed machinery, or even 测试 running motors in the service center, will encounter instances where structural resonance is amplifying machine vibration. The machine may meet stringent specifications in one instance but exceed acceptable vibration levels in another. A good understanding of natural frequencies and the 测试s necessary to identify them will help solve these vexing situations.
泵可靠性要点
The EASA Pump Reliability Seminar is a two-day program that describes in detail the factors related to pump reliability. This webinar introduces participants to those factors and how they come together to ensure a reliably operating pump.
叶轮损伤评估
The impeller is generally the most difficult pump component to repair and the most expensive to replace. This session will look at case histories of failed pumps and the steps to determine the cause of failure.
