Description

Technical Field

[0001] The utility model relates to the technical field of guide vane grinding tools, in particular to a guide vane surface grinding device. Background Art

[0002] The guide vane is the energy conversion device of the centrifugal pump, which is mainly used to collect the liquid thrown out by the impeller, reduce the flow rate of the liquid, and convert part of the velocity energy head into pressure energy head, and then evenly introduce it to the next stage or discharge it through the diffuser. The guide vane plays a role of guiding flow in hydraulic machinery. Since the guide vane needs to fit closely with the cylinder body of the centrifugal pump, in order to ensure that the accuracy of the guide vane meets the requirements, the guide vane needs to be surface ground. When performing surface grinding operations, the corresponding guide vane surface grinding device is usually used. There are many types of guide vane surface grinding devices on the market. Most of the guide vane surface grinding devices use motors to drive the corresponding grinding wheels to rotate to achieve grinding operations.

[0003] However, when this type of guide vane surface grinding device is used, it can only grind the corresponding part of the guide vane in the vertical direction, and cannot actually move the position of the grinding wheel according to the length and width of the guide vane to perform a full-scale grinding operation on the surface, which affects the grinding effect and brings inconvenience to the user. In view of this, we propose a guide vane surface grinding device. Utility Model Content
