Performance study of a diaphragm type crankcase pressure control valve
Pressure control valve (PCV) is implemented in internal combustion engine to regulate crankcase pressure. In this study, the performance of a diaphragm PCV valve is investigated numerically and experimentally. Firstly, numerical simulation is carried out using commercial code to predict the flow and pressure distribution inside the valve. Furthermore, downstream and upstream pressure of the val...
متن کاملControlling the Water Pressure in the Pressure Control Networks Using a New Automatic Pressure-Reducing Valve
Increase in urban water networks, network management is one of most important problem in which the parameters of the network pressure and leakage at night in search of networks and connections will be worn. Given that the urban water networks with more than 30 years old have been worn and is part of the network and still have not replaced the night of exhaustion and pressure leakage is due to i...
متن کاملDynamic Redesign of a Flow Control Servo-valve using a Pressure Control Pilot
In this paper, the dynamic performance of an unconventional two-spool flow control servo valve using a pressure control pilot is analyzed. Such valves are less expensive than typical servo-valves but also tend to be limited in their dynamic performance. Based on a previously developed eight state nonlinear model [1], we develop a simplified linear model which is able to capture the essential dy...
متن کاملManaged Pressure Drilling Using Integrated Process Control
Control of wellbore pressure during drilling operations has always been important in the oil industry as this can prevent the possibility of well blowout. The present research employs a combination of automatic process control and statistical process control for the first time for the identification, monitoring, and control of both random and special causes in drilling operations. To this end, ...
متن کاملVisualization of the pulmonary valve using cine MR imaging.
PURPOSE To evaluate the capability of bright-blood cine MR to directly visualize the leaflets of the valve replacement in pulmonary position following Ross operation. MATERIAL AND METHODS Long and short axis views of the pulmonary valve were obtained in 10 normal subjects and 14 patients after Ross operation. Valve morphology and function were analyzed and signal-to-noise (SNR) and contrast-t...
