Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pump processing and production, in particular to a grinding and polishing device for stainless steel pump production. Background Art

[0002] A pump is a machine that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, and can also transport liquid-gas mixtures and liquids containing suspended solids. Stainless steel pumps can transport a variety of media from tap water to industrial liquids. The flow-through parts of stainless steel water pumps are made of stainless steel plate stamping technology, which is suitable for different temperatures, flow rates and pressure ranges. Stainless steel water pumps are suitable for non-corrosive or slightly corrosive liquids.

[0003] The outer shell of the stainless steel pump is one of the parts of the stainless steel pump. The outer shell is cylindrical. During the processing, the surface of the stainless steel pump outer shell needs to be polished. However, during the polishing process, the grinding disc of the polishing device will stick to the surface of the outer shell and apply pressure to the inside of the outer shell. The inside of the outer shell lacks support. Once the operation is negligent and the grinding disc is too close to the outer shell, it is easy to cause the outer shell to be subjected to greater internal pressure, causing the outer shell to sag.
