A method for detecting leakage pressure of an electronic water pump

Abstract

The invention discloses an electronic water pump pressure-leakage detecting device, which comprises a seat plate. A plurality of supporting rods are fixedly mounted at the top end of the seat plate, amounting plate is jointly welded to the top ends of the supporting rods, two detecting mechanisms are mounted at the top end of the mounting plate and comprise supporting blocks, each supporting block is provided with three first openings, a first screw rod is rotatably mounted on the inner wall of the bottom end of the first opening in the middle, movable blocks are movably mounted on the firstscrew rods through threads, fixed blocks are welded to one sides of the movable blocks, two flush sliding rods are welded to one side of each fixed block, and the sliding rods extend into the other two corresponding first openings correspondingly. The electronic water pump pressure-leakage detecting device is novel in design and perfect in function, can be adjusted, thus adapts to electronic waterpumps with different sizes, and is high in adaptability, the pressure-leakage situation of the electronic water pumps is determined through the air pressure difference, and the effect is obvious.

Description

technical field [0001] The invention relates to the technical field of pressure detection devices, in particular to a method for detecting pressure leakage of an electronic water pump. Background technique [0002] Automotive electronic water pumps, many new energy vehicles, RVs and other special vehicles are often used in miniature water pumps as water circulation, cooling or on-board water supply systems. Such miniature self-priming water pumps are collectively referred to as automotive water pumps. The circular motion of the motor makes the diaphragm inside the pump reciprocate through the mechanical device, thereby compressing and stretching the air in the pump cavity (fixed volume), and under the action of the one-way valve, a positive pressure is formed at the drain (actual output The pressure is related to the power boost received by the pump outlet and the characteristics of the pump); a vacuum is formed at the suction port, thereby creating a pressure difference wit...
