Mud pulse generator

Abstract

The invention relates to the technical field of digital communication, in particular to a mud pulse generator. The mud pulse generator comprises a power assembly, an impeller assembly and an impellerspeed regulation load assembly, wherein the power assembly is mechanically connected with the impeller assembly and used for absorbing energy from flowing mud to drive the impeller assembly to rotate,and the impeller speed regulation load assembly is mechanically connected with the impeller assembly and used for regulating the rotating speed of the impeller assembly by changing the load. According to the mud pulse generator, the power assembly directly obtains the energy from the flowing mud to directly drive the impeller assembly to rotate, it is unnecessary to provide a generator in the prior art to supply power to a motor to drive the impeller assembly, and thus the miniaturization of equipment is achieved; and besides, a turbine is adopted in the power assembly, a generator assembly and an electrical load assembly are adopted in the load assembly, rapid regulation of the rotating speed of an impeller is achieved, and a very good foundation is laid for high-speed mud communication.

Description

Technical field [0001] The invention relates to the technical field of digital communication, in particular to a mud pulse generator. Background technique [0002] Rotary mud pulse generator is a relatively mature technology, which can realize relatively high rate data transmission. [0003] The prior art mud pulse generator generally uses a motor to drive the pulse wheel of the mud pulse generator to rotate. The motor needs to supply power to the motor to work. The common power supply method is to arrange a generator to power the motor. Therefore, this requires not only additional arrangements. In terms of energy conversion, a group of electromagnetic systems need to first convert mechanical energy into electrical energy, and then convert electrical energy into mechanical energy. In the process of multiple conversions, it will cause a large energy loss, resulting in a decrease in the energy utilization efficiency of the system. , But also not conducive to the miniaturization of e...
