A method for testing volumetric pumps
Journal of Medical Engineering & Technology, 1987This article describes a convenient method of checking the delivery rate of volumetric pumps at low flow rate settings. The method employs a tester previously described for use with syringe pumps.

Slug Testing For Pumping Wells
Annual Technical Meeting, 1990Abstract This paper proposes a variation of ‘slug test’ for sucker-rod pumping oil wells. Application of slug testing simply expedites the buildup process. A slug test is conducted by admitting a slug of reservoir liquid such that the hydrostatic head of the wellbore liquid column balances the reservoir pressure ...

Inspection and Testing of Infusion Pumps
2017Infusion pumps are ME (Medical Electrical) devices intended to regulate the intravenous flow of liquids through a positive pressure generated by the pump itself. Infusion pumps are used in all those wards where patients need life support and a proper nutrition.

Experiences With Pumping Well Testing
SPE Production Engineering, 1989SummaryThis paper presents our recent experiences with pumping well testing using the acoustic method. Three areas of testing are examined: computation of changing liquid density throughout the liquid column at every timestep, interpretation of the test with simultaneous downhole pressure and flow-rate data, and static and dynamic responses of the ...

Hardware in loop testing of an insulin pump
2015 IEEE International Test Conference (ITC), 2015System test plays a very important role in the product development cycle of a safety-critical device, such as an insulin pump. Given the significant risk of this device, fault-injection should be performed to validate dependable implementation under abnormal circumstances, namely: data corruption, bit flips, incorrect signal assertions and more ...

WELL TESTING IN THE ANNULUS OF PUMPING WELLS
Proceedings of International Meeting on Petroleum Engineering, 1986ABSTRACT Well testing technique in the annulus of a pumping well has been a subject on which great efforts have been made by petroleum scientists and engineers in recent years. Based on the practical situation in our country this paper analyzes and discusses in detail the features of such techniques developed in our country.

Aquifer pumping tests are an integral component of aquifer characterization because they provide quantitative data on large-scale aquifer hydraulic properties such as aquifer transmissivity, storativity, and the vertical hydraulic conductivity (leakance) of confining strata.

Annual Technical Meeting, 1990
Introduction Pressure transient analysis has undergone a significant development over the last two decades. Sophisticated methods of flow regime identification were developed along with the models of complex heterogeneous systems. The technology is strictly applicable to data obtained on flowing wells.

Modeling and testing of a novel piezoelectric pump
IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004While there is a wide range of actuation technologies, none currently rivals the overall performance (power density, bandwidth, stress, stroke) of conventional hydraulic actuation [1]. It is well known in the actuation community that the power-to-weight ratios and the power-to-volume ratios of hydraulic actuators are, respectively, around 5 times and ...

Research on pumps, particularly those for transporting cryogenic fluids, is very expensive. Rocketdyne has tested pumps with air as the working fluid and has found that a very good correlation exists between air test data and liquid test data. This paper gives a description of the air rigs used by Rocketdyne and compares the data taken in air with data
