Turbine with adjustable blade angle

Abstract

The invention relates to a turbine with an adjustable blade angle. The turbine comprises a wheel shaft and blades, a bearing seat is installed at the left side of the wheel shaft, the wheel shaft is fixed in a turbine seat through the bearing seat, a shaft sleeve is arranged at the leftmost end of the wheel shaft, a circle of round pipe is embedded in the shaft sleeve, and the blades rotate in theround pipe through a rotating shaft, so that the turbine type blades mounted on the shaft sleeve can achieve self rotation. A pressure-bearing rod is further welded to the bottom end of the rotatingshaft and extends into the shaft sleeve along with the rotating shaft, a rotating base rotating in a friction manner with the top face of the round pipe is arranged in the middle of the rotating shaft, the air inlet speed is decreased, and therefore the air pressure is decreased, and the air exhaust amount of an air exhaust opening at the right side can be reduced. Meanwhile, the air exhaust speedcan be reduced, when the gap between the two blades becomes large, the air inlet amount is increased, the air exhaust amount of the air exhaust opening at the right side becomes large, and thereforethe air exhaust speed and the air pressure can be changed without additionally arranging a small-diameter air exhaust pipe and a pressure regulating valve on the air exhaust opening, and the pressureof exhausted air can also be regulated.

Description

technical field [0001] The invention relates to the technical field of turbines, in particular to a turbine with adjustable blade angles. Background technique [0002] A turbine is an engine that uses fluid to impinge on the impeller to rotate to generate power. The earliest turbochargers were used in sports cars or formula cars, so that the engine could obtain more power in racing competitions where the engine displacement was limited. Can be divided into steam turbines, gas turbines and water turbines. It is widely used as a power machine for power generation, aviation, navigation, etc. The turbocharger is actually a kind of air compressor, which increases the air intake by compressing the air. There are multiple sets of blades installed in the turbine through the rotating shaft. When it is discharged, it has a high impact, and the gas has a supercharging characteristic after being discharged outside after treatment. [0003] After the blades installed on the transmiss...

AI Technical Summary

Problems solved by technology

[0003] After the blades installed on the transmission shaft in the turbine are fixed once, the angle cannot be adjusted. Therefore, the pressure of the gas discharged from the turbine cavity after changing the pressure is always the same. Therefore, it is necessary to set a pressure regulating valve on the exhaust port to adjust the pressure. However, In order to install the pressure regulating valve reasonably, it is necessary to add a thin exhaust pipe to the exhaust port, and install the pressure regulating valve on the exhaust pipe, resulting in a smaller exhaust volume and affecting the exhaust speed
