市场上自吸泵（能耗高），而其他泵又由于目前市场上底阀的密封性能差，承压小等因素导致经常不能正常使用且易烧毁，这一直是用户及厂家所面临着的一道巨大难题，我厂就以解决以上问题从而展开研究攻关，终于研制出一系列底阀。比如：在同一装置上，直径为80的升降杆铁底阀（对比产品）和直径为80的翻盖式塑料底阀（我厂），在流量为50吨/小时时，前者的扬程损失要比后者多1.75米。流量方面前者每小时抽水69.7吨。而后者每小时抽水92.04吨。吸力损耗方面，同样的抽水操作过程中，前者损耗6.33米（因铁板重量重），而后者抽水消耗只有3.15米（因塑料重量轻）。前者易生锈腐蚀，后者永不生锈，结构又先进，使用过程中异物不会滞留（导致密封不严），从而确保水泵高效率的长期有效的工作。Self-priming pump on the market (high energy consumption), while the other pumps currently on the market and since the end of the valve sealing performance is poor, small and other factors have led to pressure often can not properly use and easy to burn, which has been faced by users and manufacturers of the a huge problem, I have the factory in order to solve the above problems in order to undertake a study research, and ultimately developed a series of bottom valve. For example: In the same device with a diameter of 80 iron rod at the end of valve lift (compare products) and a diameter of 80 clamshell plastic at the end of valve (I plant), in the flow of 50 tons / hour, the former head of loss than after the by more than 1.75 meters. The former flows pumping 69.7 tons per hour. 92.04 tons per hour, pumping the latter. Suction loss, the same pumping operation, the former loss of 6.33 meters (due to the weight of heavy iron), while the latter is only 3.15 meters pumping consumption (due to light weight plastic). Former is easy to rust corrosion, which will never rust, structure and sophisticated use of the process will not remain foreign bodies (lead Mifengbuyan), so as to ensure the long-term pump efficient and effective work
