The invention discloses a natural-gas flow-temperature helium extracting system and a natural-gas flow-temperature helium extracting method. According to the system and the method, the post-expansion and nitrogen circulating refrigerating two-column separating technology is carried out for fully recovering the cooling capacity of the device in order to pre-cool the natural gas which serves as the raw material, and thereby the system can be applied to the natural gas which has an extremely low content of helium, and has the characteristics of being low in energy consumption, high in helium recovery rate, small in investment, flexible in operation, and high in adaptability to variable working conditions. The system and the method have the positive effects that little helium in the helium-containing natural gas can be extracted by a pre-cooling system and a low-temperature rectifying system, an independent nitrogen circulating refrigerating system is adopted and used for supplying an ultralow-temperature cold source required in helium concentration, and the independent system is rich in adjusting means and cannot be influenced by upstream operations; and a post-expansion refrigerating system is adopted, so that the natural-gas low-temperature helium extracting system has the operation pressure higher than that in conventional technology, and higher concentration of the helium can also be obtained at the same refrigerating temperature.

The invention provides a mechanical synthesizer of rotational speed and torque. The mechanical synthesizer comprises a main motor and gears thereof, a helper motor and gears thereof, planetary gears, driven gears and a capacitor. The planetary gears are respectively meshed with the gears of the main motor and the gears of the helper motor. The driven gears are meshed with the gears of the main motor. When difference of the revolving speed and the torque exists between the gears of the main motor and the gears of the helper motor, the planetary gears synthesize the motive power from the two different revolving speeds and torques and then transmit the motive power to the driven gears, and accordingly synthesizing and output of the motive power are achieved. Through the charge and discharge of the capacitor, the synthesizer for a revolving speed torque machine is capable of storing the reverse load complementary energy of the main motor into the capacitor when the main motor is at low load and discharging the capacitor to drive the helper motor when the main motor is at high load, and accordingly reducing the running load of the power network while synthesizing the motor power and improving the load rate and running efficiency of the motor.
