WebApr 11, 2024 · The water was supplied to both the anode and cathode with a calibrated flow of 60 mL/min using diaphragm pumps (KNF Neuberger). Electrochemical measurements began when the cell temperature, as measured by a K-type thermocouple at the cathode back plate, reached 50°C (± 1°C), which took ∼30 min for each experiment. WebSep 1, 2024 · The overall efficiency of the diaphragm pumps increases with flow rates in the range 1–20% and it is 2–4 times higher than that of peristaltic pumps. The logarithmic scale of Fig. 7 evidences a one order of magnitude difference between the electric power consumption of peristaltic and diaphragm pumps. In addition, the electric power ...

WebJun 1, 2002 · The travelling wave diaphragm pump is a new type of pump invented and patented by Dr Ian Doig, an independent consultant engineer in Australia. In this article he takes us through the details of the design, and the advantages of its non-pulsing operation and the gentle action provided by its special deformable lines.
WebJul 1, 2004 · Two of the largest high-pressure process diaphragm pumps in the world have been installed on a natural gas field in Hammerfest, Norway, on a carbon dioxide (CO 2) re-injection duty. References (0) Cited by (0) WebMay 1, 2002 · The differential air pressure across the diaphragm and corresponding internal stresses are low in comparison with similar stresses in mechanically driven diaphragm pumps that use the diaphragm to generate pressure. Discharge flow rates are adjusted by controlling the air inlet or the discharge flow, so no complex control systems …
WebThe term “leak-free” is also to be considered against the background of the quantitative leakage rate of a system. The mechanical or hydraulic actuating system remains completely outside the range of the fluid handled. The material of the diaphragm and the hydraulic actuating system limit the range of successful operation (<200). WebSep 1, 1992 · Diaphragm pumps have the advantages of providing sealless design, low maintenance, zero leakage, and no contamination of the process fluid. This paper reports on new developments in the hydraulic control and diaphragm design in metal and plastomer (PFTE and others) materials, with special attention given to sealing and fatigue.
WebA diaphragm or membrane pump is a positive displacement pump that uses two flexible diaphragms that move forward and backward to form a temporary vacuum through the pressure difference. This vacuum uses to introduce or discharge the liquid from the pump. The diaphragm acts as a partition wall between liquid and air.
WebDiaphragm pumps are invariably air driven and very compact, also no seals or packing is exposed to the liquid being pumped, which makes them ideal for handling hazardous or … flower printingWebJun 1, 1996 · Diaphragm pumps are therefore the preferred solution for the transport of toxic, dangerous or abrasive materials. Many users choose diaphragm pumps because they offer excellent sealing and because they require no maintenance.
