Aftertreatment method used for inducer machining

Abstract

The invention discloses an aftertreatment method used for inducer machining. The aftertreatment method comprises the following construction steps of a, inducer placing, b, inducer washing and cleaningand c, inducer drying treatment. According to the method, the cleaning process and the drying process are directly carried out in one treatment box, equipment cost is saved, and the price of finishedproducts is reduced; the interior of the treatment box is divvied into a left cavity and a right cavity, and two kinds of different operations of cleaning and drying are achieved through the two cavities; function circulating exchange between the two cavities is achieved through moving of a protection cover, when the protection cover is located above one cavity, the cavity serves as a drying treatment area, the other cavity serves as a feeding and cleaning area, the two cavities work synchronously, and therefore continuous aftertreatment work on inducers is achieved, and the treatment speed is effectively increased; and equipment in the two cavities is completely the same, the feeding, cleaning and drying processes of the right cavity are the same as the operation process of the left cavity, actual operation control is more convenient, and operation difficulty is reduced.

Description

technical field [0001] The invention relates to a post-processing method for induction wheel processing. Background technique [0002] The inducer is to reduce the static positive suction pressure of the centrifugal pump, which is achieved by increasing the static pressure at the inlet of the first stage impeller of the centrifugal pump by the inducer. The swirling flow through the inducer to the outflow also plays a role in reducing the net positive suction head of the centrifugal pump. In order to avoid that when the inducer is working in the overload area, the steam bubbles on the pressure surface of the vane will block the flow channel cross-section - cavitation phenomenon, we often make the design flow of the inducer and the rated flow of the centrifugal pump 1.5-- 2.3 times, so when the centrifugal pump is working, the inducer is always running in the partial load working area, and gives the centrifugal pump impeller the necessary boost. [0003] In the milling proce...

AI Technical Summary

Problems solved by technology

In the existing post-processing, for the two processes of cleaning and drying, generally two kinds of equipment are used to treat the inducer separately, which has a large workload and a large loss of energy consumption.

And the price of the two devices is also high, increasing the production cost
