A mud pulse generator

Abstract

The present invention relates to the technical field of digital communication, in particular to a mud pulse generator, comprising a power assembly, a pulsator assembly, and a pulsator speed-regulating load assembly, wherein: the power assembly is mechanically connected to the pulsator assembly, and The energy absorbed in the middle drives the pulsator assembly to rotate; the pulsator speed-regulating load assembly is mechanically connected to the pulsator assembly, and the pulsator speed-regulating load assembly regulates the rotational speed of the pulsator assembly by changing the load. In the mud pulse generator of the present invention, the power component directly obtains energy in the flowing mud to directly drive the impeller assembly to rotate, and there is no need to provide a generator in the prior art to supply power to the motor to drive the impeller assembly, thereby realizing the miniaturization of the equipment; in addition, The power component uses a turbine, and the load component uses a generator component and an electrical load component, which realizes the rapid adjustment of the impeller speed and lays a very good foundation for high-speed mud communication.
