Problems solved by technology

[0003] But its structure has disadvantages: 1) Since the high-frequency switching of the solenoid valve is controlled by the suction of the electromagnetic coil to control the on-off of the airflow, the seal is not reliable and there is leakage; 2) The frequency of the high-frequency switching of the solenoid valve is limited, generally Below 10Hz, the scope of application is narrow; 3) The service life is short, and it usually needs to be replaced after a few months or half a year, and the cost of use is high; 4) The high-frequency switching of the solenoid valve has poor working reliability and high failure rate

Embodiment 1

[0034] like image 3 As shown, a mechanical rotary pulse gas generator includes a base body 1, an end cover 2, a turntable 3, a rotating shaft 4, a driving mechanism 5, and a first sealing ring 6. The base body 1 and the end cover 2 are installed, and the middle A cavity is formed, the turntable 3 is installed on the rotating shaft 4 and placed in the cavity, the two ends of the rotating shaft 4 are respectively installed on the seat body 1 and the end cover 2 through the bearing 7, and the first seal is installed between the outer wall of the turntable 3 and the inner wall of the cavity. The ring 6, the turntable 3 and the seal ring 6 divide the cavity into a left cavity 8 and a right cavity 9 which are independent of each other. The drive mechanism 5 is located outside the cavity, and the drive mechanism 5 drives the rotating shaft 4 and the turntable 3 to rotate. An air inlet 10 is provided, an air outlet 11 is arranged on the end cover 2 to communicate with the left cavity...

Abstract

The invention relates to a mechanical rotary type pulse gas generator, comprising a seat body, an end cover, a rotary disc, a rotary shaft, a driving mechanism and a first sealing ring, wherein the rotary disc is arranged on the rotary shaft and is arranged in a cavity; the first sealing ring is arranged between the outer side wall of the rotary disc and the inner wall of the cavity; the cavity is divided into a left cavity and a right cavity which are independent by the rotary disc and the sealing ring; the driving mechanism is positioned outside the cavity and drives the rotary shaft and the rotary disc to rotate; the seat body is provided with a gas inlet; the end cover is provided with a gas outlet communicated with the left cavity; the rotary disc is provided with a gas flow channel; a sliding groove is arranged at the front of the gas inlet and on the seat body and is internally provided with a supporting sleeve capable of moving along the sliding groove; the supporting sleeve is provided with a transitional channel communicated with the gas inlet; and a spring is arranged at the bottom part of the sliding groove and supports the supporting sleeve so as to enable the supporting sleeve to extend into the right cavity and be matched with the gas flow channel by being close to the end surface of the rotary disc. The mechanical rotary type pulse gas generator has the advantages that the working is reliable, the service life is long, higher-frequency pulse gas can be generated and the sealing performance is good.

Description

Technical field: [0001] The invention relates to a mechanical rotary pulse gas generator. Background technique: [0002] At present, the pulse gas generator is mainly a solenoid valve. The input end of the solenoid valve is connected to the compressed air to start the gas, and the output end is the pulse gas output port. structured as figure 1 as shown, figure 2 It is the pulse electric signal to the solenoid valve, so that the pulse gas generator outputs pulse gas flow. [0003] But its structure has disadvantages: 1) Since the high-frequency switching of the solenoid valve is controlled by the suction of the electromagnetic coil to control the on-off of the airflow, the seal is not reliable and there is leakage; 2) The frequency of the high-frequency switching of the solenoid valve is limited, generally Below 10Hz, the scope of application is narrow; 3) The service life is short, and it usually needs to be replaced after a few months or half a year, and the cost of use...
