Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flow channel polishing, in particular to a double-flow-channel pump body polishing device and process thereof. BACKGROUND

[0002] A pump is a device that converts mechanical energy into fluid energy with the aid of external power. The flow channel of a pump refers to the "channel system" inside the pump for guiding fluid flow. It is the complete path through which fluid enters the pump body from the "inlet", undergoes energy conversion, and is finally discharged from the "outlet". It is not only a "channel" for fluid, but also a key carrier for realizing the conversion of "mechanical energy into fluid energy". Its shape, size, and surface quality directly affect the core indicators of the pump, such as efficiency, anti-cavitation performance, vibration and noise.

[0003] In pump body production, burrs, flash, and unevenness may occur on the inner wall after casting or welding forming. In addition, uneven machining allowance may cause surface roughness to exceed the standard. These problems can seriously damage the fluid mechanics characteristics inside the flow channel: rough inner walls increase fluid flow resistance, reducing the hydraulic efficiency of the pump by 5%-15% and increasing energy consumption; sharp burrs or recessed parts easily form vortexes and local pressure surges, accelerating the wear and corrosion of the inner wall of the pump body, shortening the service life of the equipment, and even causing safety hazards such as fluid delivery interruption and equipment failure. Therefore, high-precision polishing of the inner wall of the pump body and the surface of the flow channel is a key process for ensuring equipment performance.

[0004] With the advancement of technology, there are more and more types of pumps, and pump bodies are developing towards multi-flow channels. The arrangement of multi-flow channels increases the difficulty of polishing. Currently, the polishing of pump body flow channels mainly adopts manual polishing method. However, when manual polishing is performed, the tool is difficult to penetrate deeply, which not only cannot guarantee uniform polishing, but also is prone to local over-polishing or under-polishing, resulting in size precision deviation of the flow channel and affecting the hydraulic performance of the pump body.

[0005] Therefore, there is a need for a double-flow-channel pump body polishing device and process to solve the above problems. SUMMARY

[0006] In order to solve the above problems, i.e., to solve the problem of difficult polishing of pump body flow channels, the present application provides a double-flow-channel pump body polishing device and process thereof.

[0014] By arranging the auxiliary plate, after the abrasive grinds the flow channel for a period of time, the auxiliary plate is moved to the upper side of the mounting groove by moving the auxiliary plate, and the auxiliary plate is in contact with the inner wall of the flow channel, so that the part of the right angle communication part of the flow channel and the mounting groove is protected from contact with the abrasive, avoiding over-grinding and affecting the flowability of the flow channel; at the same time, due to the blocking of the auxiliary plate, the abrasive mainly flows from the gap between the two auxiliary plates, so that the flow rate of the abrasive at the right angle communication part of the mounting groove and the flow channel is small, reducing the wear of the right angle communication part of the mounting groove and ensuring the installation of the subsequent structure.

[0015] Preferably, the auxiliary plate is connected with a moving part, and the moving part is used to drive the auxiliary plate to move.

[0016] Specifically, after the pump body is polished, the abrasive is discharged from the pump body, the moving part is started, the moving part drives the auxiliary plate to rotate and move up and down, so that the gap between the auxiliary plates impacts the inner wall of the flow channel, so that the pump body vibrates, and the auxiliary plate moves horizontally to impact each part of the inner wall of the flow channel in turn.

[0017] Through the cooperative action of the moving part and the auxiliary plate, the moving part can drive the auxiliary plate to move during polishing, so that the auxiliary plate can contact the inner wall of the flow channel to protect the inner wall of the flow channel, and after polishing, the moving part can continuously impact the inner wall of the flow channel, so that the pump body vibrates and the inner wall of the flow channel is scraped, the abrasive adhered to the inner wall of the flow channel and the mounting groove is removed, and the excessive abrasive adhered to the inner wall of the flow channel is avoided to affect the subsequent processing.

[0020] Through the arrangement of the first electric push rod, the auxiliary plate can be driven to move horizontally, and through the arrangement of the first motor, the auxiliary plate can be driven to rotate.

[0021] Preferably, the moving piece further comprises a slot formed in the rotating rod, a second electric push rod is fixedly connected in the slot, a push plate is fixedly connected to the output end of the second electric push rod, hydraulic oil is arranged in the cavity between the push plate and the inner wall of the slot, a fixed sleeve is fixedly sleeved on the rotating rod, an elastic telescopic rod is fixedly connected to the fixed sleeve, and a communication groove is formed in the rotating rod, one end of the communication groove communicates with the slot, and the other end of the communication groove communicates with the internal space of the elastic telescopic rod.

[0022] Specifically, when the auxiliary plate needs to fit the inner wall of the flow channel, the second electric push rod is started, the output end of the second electric push rod drives the push plate to move, so that the push plate drives the hydraulic oil to enter the communication groove, and then enters the elastic telescopic rod through the communication groove, so that the elastic telescopic rod is elongated, and the output end of the elastic telescopic rod drives the auxiliary plate to fit the inner wall of the flow channel; when the auxiliary plate needs to be reset, the second electric push rod is reset, the elastic telescopic rod is reset under the action of its own elastic force, and the auxiliary plate is reset at the same time, and the hydraulic oil is re-pressed into the slot.

[0029] Further, a plurality of protrusions are uniformly arranged on the side of the sealing plate close to the pump body in the circumferential direction.

[0030] Specifically, when the sealing plate blocks the opening of the flow channel, due to the arrangement of the protrusions, there is a gap between the sealing plate and the pump body, which facilitates the discharge of the original gas in the pump body when the abrasive is supplied into the pump body, and avoids the mixing of the gas into the abrasive, thereby affecting the compactness of the abrasive.

[0031] In addition, the application also provides a polishing process of the double-flow-channel pump body, which comprises the following steps:
