The utility model belongs to the field of glass edge grinding machine equipment, and particularly relates to a servo-controlled manual-automatic grinding head feeding system with a linear guide rail, which comprises an upper supporting plate, a lower supporting plate and a screw rod bearing seat, the upper supporting plate is slidably mounted at the upper end of the lower supporting plate, the screw rod bearing seat is mounted at one end of the upper supporting plate, and a screw rod nut seat is mounted at the upper end of the lower supporting plate. A lead screw is installed on the lead screw bearing seat, the front end of the lead screw is connected with the lead screw nut seat, a transmission gear is installed at the rear end of the lead screw, a first gear shaft and a second gear shaft which are located on the two sides of the transmission gear respectively are rotationally connected to the lead screw bearing seat, and a motor in power connection with the first gear shaft is installed on the lead screw bearing seat. The manual and automatic integrated grinding head position adjusting function is adopted, the automatic adjusting function has the advantages of being high in precision and not needing to be guarded by personnel, and the manual adjusting function meets the rapid temporary adjusting requirement.

The invention relates to the technical field of medical equipment detection, and discloses a testing device and a testing method.The testing device comprises a liquid supply unit, a liquid inlet pipe and a liquid outlet pipe. The liquid source provides liquid for the liquid supply unit through the liquid inlet pipe, the liquid outlet can be in a closed state in the initial liquid inlet stage, and when the liquid level in the liquid supply unit rises to the position of the pressure equalizing port, due to the fact that the liquid inlet amount of the liquid inlet pipe is not smaller than the liquid outlet amount of the liquid outlet pipe, the liquid level in the liquid supply unit is not lower than the position of the pressure equalizing port; when the liquid level in the liquid supply unit is higher than the pressure equalizing port, the liquid is discharged through the pressure equalizing port to maintain the stability of the liquid level height in the liquid supply unit, so that the device can restore the pressure value of the pipe fitting to be detected in the actual application scene; the pressure borne by the to-be-tested pipe fitting in the testing process is always the pressure borne by the to-be-tested pipe fitting in an actual application scene, and meanwhile, the continuity of flowing of liquid in the to-be-tested pipe fitting is ensured, so that the technical effect of improving the reliability of quality detection of the to-be-tested pipe fitting is achieved.

An omnidirectional adjustable wind wheel device for a wind turbine generator comprises a machine shaft, a wheel frame, a blade group and an adjusting wheel disc; the wheel frame is fixedly connected to the machine shaft, and the machine shaft is used to connect the generator; the blade group comprises a plurality of blades, and the plurality of blades are arranged in a circular array with the machine shaft as the machine shaft and connected to the wheel frame; each blade comprises a wind plate and an arc plate, one side of the arc plate is connected to the wheel frame, and the other side is connected to the wind plate; one side of the wind plate is movably connected to the wheel frame, and the other side is connected to the adjusting wheel disc; the adjusting wheel disc is arranged on the machine shaft and can rotate, and its rotation drives the wind plate to swing. It can be applied to a wind wheel device for a 360° omnidirectional wind field. It is applicable to wind forces with wind speeds of 1m / s to 72m / s, and to wind states of advection and turbulence. It is simple to maintain, equipped with intelligent Internet of Things management and operation, and unattended.
