蠕铁提高电力 K 系泵的工作压力及寿命由于新泵要求保持比较高的工作压力,现有的材料已不能满足,因此发展用蠕铁齿轮来提高“K”系泵的工作压力及寿命。齿轮泵的设计要求齿轮与齿轮壳之间的公差非常小。由于齿轮或齿轮壳损坏将引起不密封而导致流量的损失。装配后要求齿轮能在高温下保持密封,超压 Worms iron to improve power K-line pump working pressure and life expectancy As the new pump to maintain relatively high working pressure, the existing material has been unable to meet the development of the use of poplar iron gear to improve the “K” Department of the pump working pressure and life expectancy. Gear Pump Design Requirements The tolerance between gear and gear housing is very small. Damage to the gear or gear casing will cause a loss of flow due to non-sealing. After assembly requires gear to maintain high temperature seal, overpressure
