概述Overview FY系列液下泵是本公司在傳統耐腐蝕液下泵基礎上，參考國外同類產品的先進技術，經改進設計而生產的新型液下泵；該泵取消了其他液下泵普遍采用的機械密封和選用了獨特的葉輪，使泵高效節能、壽命長，從而廣泛應用于石油、化工、制藥、造紙、冶金等工業。 FY series submerged pump is an updated design based upon the conventional anti-corrosion pump, processed with the advanced technology in like products abroad. Mechanical seal that is commonly applied by other submerged pumps is not used in this pump. With the distinctive impeller for high efficiency, energy conservation and long serve life, this type of pumps are widely used in the industries of petroleum, chemical, pharmaceutical, papermaking, metallurgy and etc. 特點Features 泵為立式液下泵，外形美觀，直接安裝在被輸送介質的儲存器上，無額外占地面積，從而降低了基建投入。 A vertical submerged pump with elegant profile, directly mounted at the reservoir of medium to be delivered, with no additional floor space required to economize infrastructural construction investment. 取消了機械密封，解決了其他液下泵因機械密封容易磨損而須經常維修的煩惱，節約了泵的運行成本，提高了工作效率。 Cancellation of mechanical seal, a solution to the headache of frequent servicing of other submerged pumps due to the easily worn-out mechanical seal, a saver of operational cost and a promoter of work efficiency. 采用獨特的離心式葉輪，供輸送不含固體顆粒等清潔的介質，振動噪音低，效率高；采用開式葉輪，供輸送不清潔帶有固體顆粒及短纖維的液體，運行平穩、不堵塞。 Distinctive centrifugal impeller to handle clean medium not containing solid particles, featured by little vibration, low noise and high efficiency; Open impeller to handle unclean liquid containing solid particles and short fiber, featured by stable operation and non-clogging. 使用條件 Service Conditions 被輸送介質溫度為-20～140℃ Temperature of the medium to be delivered: -20～140℃ 鑄鐵材質的泵，介質PH值在5-9范圍內。 For cast iron pumps, the PH value of medium ranging within 5-9 采用開式葉輪的泵，被輸送液體中含有的固體顆粒直徑不超過泵吸入口直徑30%為宜。 For pump with open impeller, the diameter of solid particle in the liquid to be delivered should better not exceed the 30% of the suction diameter of the pump.
