水泵汽蚀是泵站运行中存在的普遍问题,水泵汽蚀将使水泵性能下降,流量减少,效率降低。用合金粉末喷焊于水泵叶片表面,进行强化处理后,表面光滑,强度高,表面硬度可达HRC60～70,且结合能力优于电焊层,因此,有效地提高了水泵的抗汽蚀性能,叶片使用寿命延长了5～6倍;同时由于喷焊厚度较薄,价格低,加工方便,结合力强,具有极大的推广应用价值和较高的经济效益。 Pump cavitation is a common problem existing in pump station operation. Pump cavitation will reduce pump performance, reduce flow and reduce efficiency. The alloy powder is spray-welded on the surface of the water pump blade for smoothing and high strength after being strengthened and the surface hardness can reach HRC60-70, and the bonding ability is better than that of the electric welding layer, therefore, the anti-cavitation performance of the water pump is effectively improved, Blade life 5 to 6 times longer; the same time due to thin spray thickness, low price, easy processing, combined with strong, with great promotion and application value and high economic benefits.
