This utility model discloses a vibration device for a calcium sulfate whisker vibrating screen, including a vibrator. A vibrating screen is installed inside the vibrator, and a vibration device is installed on the side wall of the vibrating screen. When using this vibration device for the calcium sulfate whisker vibrating screen, the adjustable tilt angle vibration design significantly improves the screening accuracy and efficiency of calcium sulfate whiskers. Multiple sets of positioning holes on the side wall of the vibrating screen are linked to telescopic rods. The tilt angle of the screen is dynamically adjusted by a turntable driving the telescopic rods, allowing the whiskers to be fully dispersed by vibration at a specific tilt angle, preventing particle accumulation or screen blockage. Simultaneously, the telescopic vibrating rods and vibration springs work together to provide a stable amplitude.

This invention discloses a dual-channel time-sharing coordinated ultrasonic surgical control system and method, belonging to the field of ultrasonic surgical equipment. It includes a main unit control module, a peak power amplification unit, a dual-channel switching unit, a first handle interface, a second handle interface, an ultrasonic surgical handle (first and second), a foot pedal priority control module, and a parameter storage unit. The peak power amplification unit is a single-channel high-power amplification circuit with a peak output power of not less than 200W. The dual-channel time-sharing coordinated ultrasonic surgical control system and method of this invention uses a single-channel peak power amplification unit to power both handles, requiring only one set of power amplification and matching circuits. This significantly reduces the number of hardware components, lowers equipment production costs, assembly difficulty, and overall size. Simultaneously, it completely bypasses the core patent layout of foreign companies with dual-channel independent power output, resolving the patent infringement risk for domestic manufacturers.

The application discloses a metal pipe water pressure vibration testing machine and relates to the technical field of pipe performance testing. The machine comprises a rack, a water receiving tray, a control box, a vibration device, a clamping device and a folding splash-proof cover. The water receiving tray is fixedly arranged on the rack and is used for collecting leaked water during the test. The control box is fixedly arranged on one side of the rack and is internally provided with a PLC controller. The vibration device is arranged in the control box and is fixedly connected with the rack through a mounting bracket. The clamping device is arranged on the water receiving tray and is used for fixing two ends of a metal pipe to be tested. The folding splash-proof cover is arranged on the top of the rack, can be opened and closed and covers above the clamping device, and is used for preventing water splashing during the test. The metal pipe water pressure vibration testing machine adopts the above structure, a stepping motor drives a zero-adjusting screw to rotate, 1:2 proportional opposite or reverse movements are generated between an adjusting flange nut and an adjusting nut, the eccentricity of a cross slide and a driven wheel is accurately changed, and automatic adjustment of the amplitude is realized.
