Zusammenfassung:The invention discloses an automatic testboard for a second-speed self-priming pump, and relates to the technical field of self-priming pump testing, the automatic testboard comprises a rack, the top of the rack is fixedly connected with a fixing frame, and the two sides of the fixing frame are both provided with sliding holes. Through the arrangement of the positioning unit and the fixing unit, a telescopic hydraulic cylinder is started to drive a fixing rod to move downwards, due to the fact that the bottom of a clamping groove is in a splayed shape, two extrusion plates can sleeve a water inlet pipe and a water outlet pipe of the self-priming pump through the two clamping grooves, and meanwhile the fixing rod moves to drive a T-shaped rod, a bent rod and a mounting rod to continuously move downwards; the extrusion plate moves to fix the self-priming pump, so that a water inlet pipe and a water outlet pipe of the self-priming pump can be accurately positioned, the water inlet pipe and the water outlet pipe
