Development With The Engine Based On Mobile Screw Compression

Along with our country economy development, application on mobile screw compressor is more and more widely, due to constraints about operation place, engine as a driving force of the screw compressor of the diesel become more and more common.Mobile screw compressor is characterized by continuous gas supply at work, and mainly is used for field operation. The construction site often changes; the operation space is little; the maintenance condition of screw compressor is not ideal. Engine load rate is high, and for long working hours, the engine fuel consumption is pay attention to.According to the above problem, this paper illustrates the main structure of the screw compressor, analyzes the working process of the screw compressor:suction ?closed? compression and exhaust. On this basis, gas regulating method of screw compressor is summed up, and the affect of the speed on the performance of screw compressor is analyzed.Development plan is putted forward for the screw compressor with diesel engine:according to the demand for stable gas of screw compressor, the RSV variable-speed governor is designed;according to the engine smoke is lesser at the working condition of screw compressor sudden and sharp reduction, the pressure compensation device is designed;according to the screw compressor used in plain and plateau, plateau diesel engine is developed; according to the working condition of diesel engine, fuel consumption area of the diesel engine is designed; according to the exhaust flow and the exhaust pressure of mobile screw compressor, the rated power and speed of diesel engine is computed; according to the discharge pressure of mobile screw compressor, the largest torque of diesel engine is computed.After screw air compressor unit, screw air compressor unit displacement and exhaust pressure meet the design requirements, plant commissioning test, sudden load and thermal balance test pass.Finally,according to the screw compressor, work environment and the operating conditions of diesel engine adaptive development. In short, in this paper, development of the diesel engine is completely suitable for screw compressor...
