【Abstract】 Make use of the single - screw pump is moreand more common in the fields of construction engineer-ing, oil industry, textile industry, food industry,medicine industry and so on. The main cause of failure forthe single - screw pump is the wear of the rotor surface.There is not a kind of reliable and economic method whichcan repair it. This situation causes waste and reduces theproductivity. We have researched the wear principle of thesingle - screw pump rotor. A few surface repair methodshave heen tested. The conclusion is that the brush platingis a kind of ideal method to repair the rotor wear surface ofsingle - screw pump. A lot of experiments have beendone, we have determined the repair technology process ofthe single -serew pump rotor wear surface. It supplies areliable method to solve the practical problem.更多还原
