Research and Application of One New Style Hot Work Die Steel for Precision Forging Die to Valve
Nowadays, mould technology has been an important symbol that can measures the manufacturing of one country ability.In this paper, we studied one new style of hot work die steel (RJD steel) for precision forging to valve. The application of this new style of hot work die steel can increase the life of precision forging die [...]
Research on Valve Intelligent Fault Diagnosis System of Reciprocating Compressor
Reciprocating compressors are widely used in petrochemical enterprises, which directly affect the state economic efficiency of enterprises. Therefore, carrying on the condition monitor and fault diagnosis for reciprocating compressors are seemed to be particularly important and meaningful.In this paper, the object of study is valve. Paper starts from the structure of reciprocating compressor, through valve [...]
The Study of Simulation System of the Valve’s Eccentri City Sitting Features Based on Catheter Gap
Based on the valve’s eccentricity sitting model has been developed,the thesis compares the difference between DesignModeler which is subjected to ANSYS-Workbench and the PRO/E.The PRO/E has much more advantage than DesignModeler in designing and assembling three-dimensional objects.With the help of PRO/E,the eccentricity sitting model can be easily finished.Based on the valve’s eccentricity sitting theoretical analysis [...]
The Research and Development of Valve CAPP System Based on Drawing Tools
Computer Aided Process Planning (CAPP, Computer Aided Process Planning) is bridge and link of the connection computer-aided design (CAD) and computer-aided manufacturing (CAM) , it is the key technology areas of enterprise product design data into manufacturing data , is one of the basic techniques about advanced manufacturing system .With the integrated environment turn toward [...]
Study of Vibration and Noise Characteristics Fluid-solid Coupling of the Valve of the Water Pipeline System
There is a broad engineering background for the problems of vibration and noise of water pipeline system and its working process is attended by fluid-solid coupling. As one of the main noise source of water pipe, vibration and noise of valve is an important component of water pipeline system’s vibration and noise. Therefore, For the [...]
Development of Performance Testing System for Pressure Control Valve
Valve is widely used as a pressure control component in the control systems in the field of aerospace. In recent years, with the continuous development of aerospace technology, the valve’s performance is made a higher requirement, the stability of the valve’s performance not only affects the system’s control accuracy, sometimes, it even has a effect [...]
The Application Research on Acoustic Emission Technique for Fault Detection of Valve Leakage
Valve is a sort of indispensable equipment used for controlling fluid flow in power plant. The efficiency of thermal power units would be greatly reduced, or even there is a direct threat to the safety operation of staff and units, as soon as an important valve leaks. At present, all the leakage detection methods of [...]
Mechanism Study of the Air Discharge Scarcity of the Piston Air Compressors in the Coal Desulfurizing Plant and the Alteration Measures
Air compressors are the machines for compressing the air and increasing air pressure or transportation of the air. Improving the running efficiency of air compressors is of great significance for the manufacture and energy saving. The main representation of the fall of running efficiency of air compressors is the air discharge scarcity. Based on the [...]
The Research of Temperature Rise by Throttling and Thermal Deformation of Hydraulic Valve
Hydraulic valve is the key component in fluid transmission and control technology, which controls the fluid pressure, flow rate and flow direction, thus its properties have a decisive influence on the whole hydraulic system. Hydraulic spool valve and poppet valve are two kinds of the basic configurations. Due to the matching clearance of the spool [...]
The Research on Valve of 3NB-1300 Drilling Pump
Based on the 3NB1300 drilling pump’s parameters, this thesis is to reveal the drill pump valve which in the high pressure fluid called drilling fluid.The movement of drilling valve and its impact stress distribution will be revealed. The purpose of valve’s service life can be imprvoved. From the valve’s law of motion, closing phase of [...]
