LEWA pulsation studies — Introduction Especially for reciprocating positive displacement pumps, interactions with connected pipelines and system parts must be taken into consideration. An installation check can ensure right from the planning stages that the overall system (both pump and pipeline) will work reliably, using precise calculation to avoid typical operational problems such as: cavitation, excessive pressure pulsations, fatigue damage to pipelines and components. We recommend carrying out an acoustic analysis for: Optimum design: Analysis of the interaction between the pump and...

LEWA pulsation studies — Advantages LEWA pulsation studies. The advantages at a glance. Efficient LEWA creates acoustic analyses (pulsation studies) in-house. This saves you the detour of dealing with an external service provider and makes carrying out the studies extremely efficient. Expert Our decades of experience as a pump and system manufacturer flow directly into the analysis. One-of-a-kind We are the world's only pump manufacturer who can carry out numerical simulations and check them against API 674 criteria. Detailed At the end, we provide you with a final report including a...

LEWA pulsation studies — Calculation methods Project US P3010B 3 I dampener Case 1 pipe SAT - Z91 - prAUi.iai:: Two modeling variants are available, which are called Approach I and Approach II based on the API 674 standard. Both methods use a state-of-the-art numerical calculation method. Approach I Based on a greatly simplified model of the network, which is suitable in most cases for pipeline systems with pumps with small to medium hydraulic power. In this method, the main pipeline section and the area surrounding the pump are studied. The acoustic influence of branches and fittings is...

LEWA pulsation studies — Required information Required information To carry out an acoustic study, we need the following data from you: – luid data: Density, viscosity, sound velocity, vapor pressure F – etailed description of the operating states: D – hich pump is running (if multiple pumps are running W simultaneously: at what offset to each other are they running?) – troke frequency S – alve configuration (which are open/closed?) V – hich fluid is pumped? W – nformation about the pressures on the intake and discharge side I – chematic sketch (including length specification/pipeline...
