Abstract
The utility model discloses a pump shell water seal pressure test device, relates to the technical field of pump part detection equipment, and aims to solve the problems that a pipeline of an existing device is tedious to disassemble and assemble, and the butt joint deviation of a pump shell is large. The device comprises a lifting frame, a fixing frame, a fixing plate and a servo motor are arranged on the lifting frame, the fixing plate is connected with a lifting frame through an air cylinder, the lifting frame is matched with a T-shaped connecting frame, and the connecting frame is matched with a T-shaped fixing sleeve on the fixing plate; the servo motor is connected with a double-thread screw, the screw is sleeved with a nut, the nut is connected with a movable frame, the movable frame is provided with a pipeline and a U-shaped connecting opening, a positioning frame with a spring penetrates through the movable frame in a sliding mode, and the nut is provided with a positioning groove; the lifting frame is provided with a limiting rod and a supporting frame, and the pipeline is erected on the supporting frame. During working, the pump shell lifting frame ascends to be in butt joint with a pipeline, the screw driving pipeline is connected with a pump shell flange, and soapy water is coated for leakage detection after water injection and pressurization; the movable frame and the pipeline can be detached by lifting the positioning frame. The device realizes quick disassembly and assembly of the pipeline, greatly shortens the operation time, and improves the detection efficiency.
