Compound turbo system can achieve a good match with the diesel engine in the whole range of operating conditions, improving diesel power

Energy shortage and environmental pollution are two major challenges that face the world today, the development of efficient, clean diesel engine is a key issue in the study. Conventional exhaust gas turbocharger is difficult taking into account the high-speed, low-speed diesel engine operating conditions, the simultaneous existence of part-load economy and acceleration performance and poor. Compound turbo system can be implemented in the whole operating range of diesel engines with a good match, improving the engine power, economy and emissions, has drawn  Stainless steel needle valve  at home and abroad. Firstly, the use of software to establish a composite turbocharged diesel engine simulation model and numerical simulation. The simulation results show that the composite turbocharged engine to improve low-speed, high-speed power and economy. Meanwhile, the composite obtained by numerical simulation turbo intake system and exhaust bypass valve bypass valve control strategy provides a reference for the trial.  2 way manifolds  optional turbocharged, engine bench tests conducted research complex turbocharged. Were matched based on the high-pressure stage turbocharger optimal fuel economy principles. Composite turbocharged program conducted to determine control strategies of different speed and load, the effect of the exhaust bypass valve and the intake bypass valve opening on engine performance, determine the total working conditions and wastegate intake bypass valve opening degree control.

The sampling device built experimental platform, the use of computer testing system, made ​​a lot of model validation experiments

In the preliminary design and manufacture of sampling device for the study, that the simulation platform, the establishment of the new sampling device simulation model. In order to verify the correctness of the simulation model, the authors of the sampling device built  Instrument valve manifolds  platform, the use of computer testing system, made ​​a lot of model validation experiments. Experimental results show that the authors constructed a  Valve manifold  model is correct, can be used as a basis for 2 way manifolds . Since the authenticity of systematic sampling of materials depends largely on the stability of the sampling rate of the car, so the author based on the simulation model, the process of reclaiming speed stability issues detailed study draws some important conclusions. Its main tasks are: Introduction to sampling system structure and working principle, a simulation model of the system, and using the model to analyze the sampling process speed load characteristics;

Butterfly cushion valve with automatic opening and self-closing feature

Butterfly cushion valve is general machinery products. Domestic production of butterfly cushion valve, the main structure of the same type and applies only in the sealing temperature differ. Butterfly cushion valve with automatic opening and self-closing  2 way manifolds  automatic valves, pressure loss also has shortcomings, is a traditional blast furnace  Instrument valve manifolds  supporting devices. In this paper, the technological transformation of check valves, check valves shall be  Trunnion ball valve  a control system, not only did not change the check valve automatically opens, auto-off function, but also it has the energy-saving features, while improving the prevention and control of non-return valve BF axial fan surge and counter functions....
