Problems solved by technology
And in the actual operation, the oil temperature is higher than 95 ℃, so that the water in the cooler is easy to scale and block, causing failure
[0007] In addition, when the hydraulic coupling fails, the equipment can only stop running, the maintenance amount is large, the secondary cost is too high, and the production is seriously affected

The invention discloses an engine power turbine system comprising a power turbine, an electronic control clutch, an electronic control unit, and a speed sensor. The power turbine is pushed by energy of engine exhaust to generate mechanical energy. One end of the electronic control clutch is connected with an engine gear system, and the other end of the electronic control clutch is connected with a gear of the power turbine. The output end of the electronic control unit is connected with an electronic control actuator of the electronic control clutch so as to control engagement or disengagement of the electronic control clutch. The speed sensor is connected with the input end of the electronic control unit and used for detecting engine speed and transmitting speed signals to the electronic control unit. The electronic control clutch is added between the power turbine gear and the engine gear system, so that the power turbine is connected with the engine gear system to drive a crankshaft to rotate for positive work only when outputting positive work, the power turbine is disengaged with the engine gear system in other times, useful work of an engine is not consumed, operation reliability is high, and maintenance is facilitated.
Description
technical field [0001] The invention relates to the field of engines, in particular to an engine power turbine system. Background technique [0002] Existing power machinery such as diesel engines, gasoline engines, and natural gas engines use power turbine systems to convert engine exhaust gas energy into mechanical energy, which is transmitted to the engine gear train through a hydraulic coupling, and finally drives the crankshaft to rotate, increasing the output power of the engine. [0003] The hydraulic coupling is a power loss control (mechanical) speed regulating device. With the advancement of technology, the hydraulic coupling gradually shows the following limitations: [0004] First of all, the hydraulic coupling is a speed control device with power loss control. Through actual measurement, it is found that after the engine is equipped with a power turbine device with a hydraulic coupling, the power turbine can give a driving force to the crankshaft through the gea...
