Design considerations and performance evaluation of a surge tank for diaphragm pump operation

Özdemir, Şahika
This thesis is performed to evaluate the design consideration and performance characteristics of a surge tank for a diaphragm pump operation and to evaluate the proper volume and inlet area of surge tank in order to reduce the pulsations of the discharge pressure. An experimental set up is constructed for a three diaphragm positive displacement pump and the experiments are conducted afterwards. The surge tanks having different volumes and the surge tank inlet area configurations are tested in order to achieve the minimum peak to peak pulsations. Experiments showed that among the different sizes of the surge tanks, the minimum peak to peak pulsations are achieved with the largest volume which is the original surge tank of the test pump used by the pump manufacturer. This result is supported by the literature which states that with greater surge tank size the magnitude of pulsations can be diminished more. Regarding the surge tank inlet area design; among the eight different adaptors a proper inlet area value is concluded having the minimum peak to peak pulsations also smaller than the original configuration.


Investigation of waterhammer problems in the penstocks of small hydropower plants
Çalamak, Melih; Bozkuş, Zafer; Department of Civil Engineering (2010)
Waterhammer is an unsteady hydraulic problem which is commonly found in closed conduits of hydropower plants, water distribution networks and liquid pipeline systems. Due to either a malfunction of the system or inadequate operation conditions, pipeline may collapse or burst erratically resulting in substantial damages, and human losses in some cases. In this thesis, time dependent flow situations in the penstocks of small hydropower plants are investigated. A software, HAMMER, that utilizes method of chara...
Performance evaluation and cfd analysis of a positive displacement diaphragm pump
Gökçe, Gökay; Albayrak, Kahraman; Department of Mechanical Engineering (2011)
In order to understand flow characteristics inside a positive displacement pump, every point in the flow field must be carefully observed. Such observations are difficult, expensive and usually time consuming to achieve with physical testing. During tests one can observe flow characteristics only at the locations where the instrument device is attached, not the whole flow domain. This thesis mainly focuses on the evaluation of design and performance characteristics of a positive displacement triplex diaphra...
Performance analysis of a solar-assisted heat pump with an evacuated tubular collector for domestic heating
Caglar, Ahmet; Yamali, Cemil (2012-11-01)
Performance of a solar-assisted heat pump with an evacuated tubular collector has been analyzed both theoretically and experimentally. A domestic heating system has been designed, constructed and tested. The evacuated tubular solar collector has been used to achieve higher collector efficiencies. The effects of evaporation temperature on the heating capacity and performance of the system have been investigated. Evaporation temperature varies between 5.2 and 20.7 degrees C while storage tank temperature vari...
Mathematical expression of the temperature profile and experimental determination of compression heating of ethylene glycol during high hydrostatic pressure processing
Buzrul, S.; Alpas, Hami; Largeteau, A.; Demazeau, G. (Informa UK Limited, 2007-03-01)
In this study, we aimed to describe the temperature profile in the pressure vessel and the compression heating during high hydrostatic pressure (HHP) processing. Regression coefficients (R-2), root mean square error (RMSE) values and residual plots suggested that fourth-order polynomial function produced reasonable fits to define the temperature profile for all the pressures studied (300-600 MPa). If all the coefficients of this empirical model are determined, initial and final temperatures, a value close t...
Modeling and experimental evaluation of variable speed pump and valve controlled hydraulic servo drives
Çalışkan, Hakan; Balkan, Raif Tuna; Department of Mechanical Engineering (2009)
In this thesis study, a valveless hydraulic servo system controlled by two pumps is investigated and its performance characteristics are compared with a conventional valve controlled system both experimentally and analytically. The two control techniques are applied on the position control of a single rod linear actuator. In the valve controlled system, the flow rate through the actuator is regulated with a servovalve; whereas in the pump controlled system, two variable speed pumps driven by servomotors reg...
