Problems solved by technology
[0004] At present, pulse jets are mainly divided into two types: self-excited oscillating and other-excited. Among them, the mechanism of self-excited oscillating pulsed jets is complicated, the pulse oscillation frequency is difficult to adjust, and the requirements for supply pressure, nozzle structure, and surface roughness of the flow channel are too high. High, not suitable for specific applications, but for other exciting pulse jets, its principle is simple, parameters are easy to control, and its application range is wide, it has become a research hotspot in the field of pulse jets
[0005] In current industrial applications, an additional drive mechanism is often used to modulate and excite the continuous jet to generate a pulsed jet. The integration level is low, and the redundant electro-hydraulic drive source increases the complexity and instability of the system. The system is reliable. Sex and security are not high
For example, the invention patent with the application number CN200610021427.5 discloses a variable frequency pulse jet device, which uses a frequency converter-motor to drive an external turntable to modulate the continuous jet, which not only reduces energy utilization, but also increases circuit failure and safety. Hidden dangers; for example, the invention patent with the application number CN201510287419.4 discloses a blocking hydraulic pulse generation device and method, which uses a hydraulic motor to periodically block the radial flow channel to generate a pulse jet, and its installation size Larger problems with low system reliability

The invention relates to a water conservancy self-driven independent excitation pulse jet flow generating device and a generating system thereof. A modulating passageway and a jet flow passageway areseparately designed, drive fluid flowing through the modulating passageway drives a squirrel cage type blocking cage to rotate, and therefore high-pressure pulse jet flow is obtained. Compared with the prior art, no additional drive source is needed for obtaining the high-pressure pulse jet flow, and therefore the device has the beneficial effect of being high in reliability.
Description
technical field [0001] The invention relates to the technical field of water jets, in particular to a water conservancy self-driven pulse jet generating device and a generating system. Background technique [0002] Water jet technology is an advanced material processing technology, which is widely used in machinery manufacturing, vein mining, military technology and other fields due to its advantages such as low mechanical vibration, no dust generation, and low cutting heat. [0003] Pure water jet technology has developed rapidly in recent years, and has gradually formed three main systems: continuous jet, pulse jet and cavitation jet. Among them, due to the water hammer effect of incompressible fluid, the pulse jet can generate huge instantaneous impact pressure at a low supply pressure, and it is easy to control the jet parameters when it is generated by manual modulation, which has obvious application advantages. [0004] At present, pulse jets are mainly divided into t...
