Manufacturing method of steam-liquid full-flow screw power machine with double steam inlets

1. This utility model relates to a vapor-liquid full-flow screw power machine, especially a vapor-liquid full-flow screw power machine with double steam inlets.

Background technique:

2. Vapor-liquid full-flow screw power machine, including casing, driving screw rotor, driven screw rotor, rotor shaft mechanical seal device, rotor shaft synchronous gear, rotor shaft bearing, low pressure end block, high pressure end block; active screw meshing with each other The rotor and the driven spiral rotor are installed in the casing. The synchronous gears, bearings, and mechanical seals of the spiral rotor shaft are installed in the low-pressure end block and the high-pressure end block respectively. The end butt bolts are fixedly connected, and steam inlet and exhaust ports are provided at both ends of the casing. The high-pressure water vapor of the steam-liquid full-flow screw power machine enters from the steam inlet to drive the spiral rotor to rotate, and then is discharged from the steam outlet to convert the energy of the heat source into power output.

3. When the vapor-liquid full-flow screw power machine is used to replace the temperature and pressure reduction device, the temperature and pressure of its outlet must be controlled. But often the steam volume (inlet steam volume) of the steam-liquid full-flow screw power machine is insufficient, the pressure difference between the inlet and exhaust steam is small, and the matching expansion ratio is small, so the power (output) of the steam-liquid full-flow screw power machine cannot be fully utilized and cannot be effective. To increase the steam exhaust volume for temperature reduction and pressure reduction.
