Description

Technical Field

[0001] The utility model relates to a cleaning device for gear pump production, belonging to the technical field of gear pump cleaning. Background Art

[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume created between the pump cylinder and meshing gears to transport liquids or increase pressure. Two gears, a pump body, and front and rear covers form two enclosed chambers. As the gears rotate, the volume of the chamber on the disengaged side increases from smaller to larger, creating a vacuum that draws liquid in. The volume of the chamber on the meshing side decreases from larger to smaller, squeezing the liquid into the pipeline. The suction and discharge chambers are separated by the meshing line of the two gears. The pressure at the discharge port of a gear pump is entirely dependent on the resistance at the pump outlet.

[0003] In the prior art, for example, the Chinese patent number CN 218424527 U, titled "A Cleaning Device for Gear Pump Production," includes an outer chassis with a chassis cover on the top; a water tank is fixedly connected to the bottom of the chassis cover, a plurality of ultrasonic transducers are fixedly connected to the outer wall and the bottom of the water tank, an ultrasonic generator is provided in the inner cavity of the outer chassis, and a positioning mechanism is provided on the top of the water tank; the positioning mechanism includes two positioning plates, a plurality of water holes, four fixed rods, a telescopic rod, a hydraulic cylinder, a top frame, and four protective plates, a plurality of water holes are opened on the upper surface of one of the positioning plates, the fixed rod and the protective plate are arranged between the two positioning plates, the telescopic rod is arranged between the hydraulic cylinder and the other positioning plate, and a plurality of limiting mechanisms for positioning gears, etc. are fixedly connected to the lower surface of the other positioning plate. The beneficial effect is that the utility model utilizes the arrangement mode of cooperating the positioning mechanism and the limiting mechanism to facilitate respectively mounting the gears and the front and rear covers on the gear pump on the limiting mechanism, and through the hydraulic cylinder and the telescopic rod, the gears and the front and rear covers can stably enter the inner cavity of the water tank, preventing the gears or the front and rear covers from moving arbitrarily in the inner cavity of the water tank, and through the cooperation of the ultrasonic generator and the ultrasonic transducer, it can stably clean the dirt on the gears and the front and rear covers.

[0004] However, in the prior art, the gear pump cleaning method is generally to directly place the gear of the gear pump component directly into the inner cavity of the cleaning machine. During the cleaning process, the gear component and the inner cavity of the cleaning machine are prone to position shifting, thereby generating friction. If the gear component being cleaned is not well fixed, the fixed gap will not be cleaned properly, thereby reducing the cleaning effect. Utility Model Content
