Self-priming pump body and pressure resistance testing machine thereof

Abstract

The invention relates to the technical field of self-priming pump detection, and discloses a self-priming pump body and a pressure resistance testing machine thereof.The self-priming pump body comprises a base, a driving motor is fixed to the base, a shell is fixed to the base, a driving cover is fixed to one side of the shell, a transmission rod is rotationally arranged in the driving cover, and the output end of the driving motor is connected with an impeller in the shell through the transmission rod; a water inlet is fixed to one side of the shell, a water outlet is fixed to the shell, the pressure resistance testing machine comprises a machine table, a material conveying table is fixed to the machine table, two testing tables are fixed to one side of the material conveying table, material conveying rollers are rotationally arranged on the material conveying table in an array mode, two discharging ports are formed in one side of the material conveying table, a first air cylinder is fixed to one end of each testing table, and a circular plate is fixedly arranged at the output end of the first air cylinder. The first test piece is used for testing the interior of the self-priming pump, impact of sundries in conveyed liquid on the interior of the pump body of the self-priming pump can be simulated, the second test piece is used for detecting the exterior of the self-priming pump, the compressive strength of the pump body of the self-priming pump is tested, and the detection precision is high.
