Description
Technical Field
The invention belongs to the technical field of water jet, and particularly relates to an energy storage type pulse jet generating device.
Background
The water jet technology is a new technology related to multiple disciplines, has been rapidly developed in recent decades due to the increasingly widespread application thereof, and pulse water jet is generated in order to improve the hitting power and the working efficiency of the water jet. The pulse jet flow is non-continuous jet flow, the water flow ejected by the generator periodically acts on the target, the image of the intermittent jet flow is similar to that ejected by a bullet, the pressure of the continuous jet flow is far greater than that of the continuous jet flow under the same pressure, and the pulse water jet flow utilizes huge transient energy generated by hydraulic impact-water hammer action, so that the aim of better cutting or crushing materials is fulfilled without increasing the pressure.
The pulse water jet can be divided into a self-excited type and a separately excited type according to the generation principle. The self-excited pulse jet is a novel high-efficiency pulse jet developed by utilizing the principles of hydromechanics, fluid resonance, fluid elasticity, hydroacoustics and the like, and generates oscillation in a special fluid structure through self-excitation to convert continuous jet into pulse jet, wherein the self-excited oscillation pulse jet has the advantages of simple structure, good sealing performance, high reliability, low cost and the like, for example, the self-excited air suction type pulse jet nozzle disclosed by the invention patent with the publication number of CN102069049, and the like. However, since the mechanism of generation of the self-oscillating pulsed jet is complicated, it has not been fully disclosed yet, and thus how to apply it more effectively is still a problem.
Most of the pulse jet flows used in the industry at present are of a separately excited type, and the separately excited pulse jet flows are mainly formed by periodically blocking or extruding the jet flows through other devices, so that the jet flows act on a target piece discontinuously. The pump-less high-pressure pulse jet generator disclosed in patent publication No. CN105478272A generates high pressure by the reaction of hydrogen and oxygen to push the piston to generate pulse jet, but this solution has the problem of generating high pressure at the time of gas reaction and pushing the piston to move, so that the whole system generates pressure holding and impact, which certainly shortens the service life of the system. The invention patent with publication number CN111395963A discloses a water conservancy self-driving type laser pulse jet flow generating device and generating system, through separately designing a modulation flow channel and a jet flow channel, no additional driving source is needed, but the whole system structure is more complicated, and is not beneficial to maintenance.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the energy storage type pulse jet generating device comprises a water pump 1, a water inlet pipe 3, an energy accumulator 4, a water outlet pipe 6 and a pulse jet generating assembly 5.
The pulse jet generating assembly 5 comprises a shell 53, a piston 55, a front end cover 52, a rear end cover 56, an electromagnet 51 and an annular retainer ring 532. The water pump comprises a shell 53, and is characterized in that the side walls of the two ends of the shell 53 are respectively provided with a water inlet pipe connector and a water outlet pipe connector 533, the water pump 1 is connected with the water inlet pipe connector 531 of one end of the shell 53, namely the water inlet end, through a water inlet pipe 3, the water inlet pipe 3 is further connected with an energy accumulator 4, and the water outlet pipe 6 is connected with the water outlet pipe connector 533 of the other end of the shell 53, namely. The housing 53 is preferably a hollow cylindrical structure, and the water inlet pipe connection 531 and the water outlet pipe connection 533 are respectively perpendicular to the cylindrical axis of the housing 53. The front end cover 52 covers the water inlet end of the shell 53, the rear end cover 56 covers the water outlet end of the shell 53, and the electromagnet 51 is installed outside the front end cover 52.
The annular retainer ring 532 is installed inside the housing 53, is located between the water inlet pipe connector 531 and the water outlet pipe connector 533, and is close to the water inlet pipe connector 531, and divides the inside of the housing 53 into two parts.
The piston 55 is installed inside the housing 53 between the annular retainer 532 and the rear end cover 56 and the piston rod 553 thereof extends from the rear end cover 56, the piston head 551 of the piston 55 is circumferentially provided with a V-shaped groove 552, the V-shaped groove 552 is provided with a piston ring 54, and the piston ring 54 prevents the head of the piston 55 from directly contacting with the housing 53, thereby reducing friction, prolonging the service life and simultaneously playing a sealing role. A collar 57 is mounted on the rear end cap 56 for sealing, preferably, the collar 57 is a stepped copper collar, and a piston rod 553 of the piston 55 penetrates out of the collar 57.
The annular retainer ring 532 is provided with a buffer gasket towards one side of the piston 55, the rear end cover 56 is provided with a buffer gasket towards one side of the piston 55, and the buffer gasket limits the piston 55 and reduces the collision between the front end cover 56 and the rear end cover 56.
Preferably, the front and rear end caps 52, 56 are respectively threadedly connected to the housing 53, it being understood that the front and rear end caps 56 may be sealed to the housing 53 using mounting methods known in the art.
When the system works, the water pump 1 is opened, pressure is provided for the whole system through the water pump 1, and the water inlet control valve 2 and the water outlet control valve 7 are opened. The electromagnet 51 is electrified, at the moment, the piston 55 is tightly attached to the buffer gasket on the circular ring-shaped retainer ring 532 under the action of the electromagnet 51, the inner channel of the shell 53 is blocked, and the energy accumulator 4 starts to accumulate energy. When the pressure reaches the required value, the electromagnet 51 is powered off, at this time, due to the pressure of the water, the piston 55 accelerates backwards until contacting with the buffer gasket on the rear end cover 56, and simultaneously, the water flows out through the water outlet pipe connecting port 533, sequentially passes through the water outlet pipe 6 and the water outlet control valve 7, and finally is sprayed out from the nozzle 8. When water is sprayed from the nozzle 8, the electromagnet 51 is electrified, and the piston 55 starts to move forwards due to the magnetic force until the piston contacts with the buffer gasket on the circular ring-shaped retainer ring 532, so that one cycle of movement is completed. By continuously repeating the above-mentioned action process, the pulse jet can be realized.
