Diagnostic system to determine the in-service life of dry vacuum pumps A diagnostic system for dry pumps is proposed. It predicts future pump motor current from time-series in-situ measurements. The prediction system has been ... S.,Konishi,K.,... - 《Iee Proceedings A Science Measurement ...
The water enters the pump from the top left and passes through each of the four impellers in series, going from left to right. The water goes from the volute surrounding the discharge of one impeller to the suction of the next impeller. A pump stage is defined as that portion of a ...
Wear is a common issue in the operation of emulsion pumps. When it becomes severe, it can lead to machine downtime and economic losses. This paper aims to investigate the wear phenomenon on the slideway of emulsion pumps using Archard’s wear model and t
The Knudsen pump (KP) is a kind of micro-pump that can form thermally induced flows induced by temperature fields in rarefied gas environments. It has the advantages of having no moving parts, simple structure, easy construction and extension, a wide range of energy sources, and low energy ...
Pipes in Parallel Find discharge given pressure at A and B ___& ___ equation add flows Find head loss given the total flow assume a discharge Q1’ through pipe 1 solve for head loss using the assumed discharge using the calculated head loss to find Q2’ assume that the actual flow is...
To provide manufacturers of fluid systems with more benefits in terms of low pulsation, KNF developed the FP pump series that has an almost constant and non-pulsating flow rate at the pump’s inlet and outlet. This results in the decisive advantage that the behavior in a system is easily pr...
Pump drive Shaft options for Group 2 gear pumps include tapered, tang, splined, or parallel shafts. They are suitable for a wide range of direct and indirect drive applications for radial and thrust loads. Plug-in drives, acceptable only with a splined shaft, can impose severe radial loads ...
