技术领域Technical field
本实用新型涉及离心泵检测的领域，具体涉及一种卧式泵泵壳与导叶同心度、平面度检测工装。The utility model relates to the field of centrifugal pump detection, and specifically relates to a horizontal pump housing and guide vane concentricity and flatness detection tool.
背景技术Background technique
依据现有的零件常规测量技术，不锈钢卧式单级离心泵中泵体与导叶的检验工具通常是游标卡尺和深度尺，仅依靠检验员的测量经验和目视读取数据，造成了不同零部件之间存在较大差异，从而影响产品质量特征值，在装配过程累计误差增加，呈现不可控现象。泵壳与导叶的安装配合尺寸超差，与叶轮安装孔不同心，会导致叶轮与泵壳擦牢，产生噪音及阻力，造成电机功率上升，从而性能下降的情况。在装配过程中发现此问题会降低生产效率。针对此种情况，我们设计了一个专门用于泵壳和导叶的检测工具。有效的保证了产品质量。According to the existing conventional parts measurement technology, the inspection tools for the pump body and guide vanes in stainless steel horizontal single-stage centrifugal pumps are usually vernier calipers and depth gauges. They only rely on the inspector’s measurement experience and visual reading of data, resulting in different zero There are large differences between components, which affects the product quality characteristic value, increases the cumulative error during the assembly process, and presents an uncontrollable phenomenon. The installation and matching dimensions of the pump casing and guide vane are out of tolerance and are not concentric with the impeller installation hole, which will cause the impeller and pump casing to rub tightly, generate noise and resistance, cause the motor power to increase, and thus the performance to decrease. Discovering this problem during assembly can reduce production efficiency. In response to this situation, we designed a testing tool specifically for pump casings and guide vanes. Effectively ensure product quality.
