产品概述Product description
WSY系列泵为立式玻璃钢液下旋涡泵。FSY系列泵为立式玻璃钢液下离心泵。该泵因伸入贮罐，贮槽的深度长短不同，设计液下深度有800mm～5000mm之间任意选择。只要液体高于泵体，即可不灌液而起动送液，平盖板下设有泄漏孔，液体不会向贮罐外泄漏。
本泵与介质接触的零部件，系用聚乙烯醇缩丁醛改性酚醛玻璃纤维，经高温模压成型的酚醛玻璃钢制件，联接管、出液管采用半干法卷制工艺制成的酚醛玻璃钢管，叶轮轴套的装配均用酚醛胶泥和泵轴粘成一体，液下各部装配均用酚醛胶泥粘结，伸入液下全无金属与介质接触，耐腐性能可靠，产品具有轻质、高强、不变形、耐温、耐腐蚀等优良性能，在防腐方面可部分替代含钼不锈钢、钛及钛合金等贵重金属。
本泵广泛用于化工、石化、冶炼、染料、农药、制药、稀土、化肥等行业，在贮罐上输送不含悬浮固体颗粒，不易结晶，温度不高于100℃的各种非氧化性酸(盐酸、稀硫酸、甲酸、醋酸、丁酸)等腐蚀介质的最理想设备。
WSY series is vertical glass reinforced plastic submerged vortex pump. FSY series is vertical glass reinforced plastic underwater centrifugal pump. This pump will stretch into the storage tank. As the depth and length of storage tanks are different, the underwater depth is designed between 800mm～5,000mm freely optional. Provided that liquid level is higher than the pump body, there will be no need of priming liquid to start. Leak hole is fitted under flat cover board, so that liquid will not leak out of the storage.
The components in contact with medium are made of phenolic glass fibre modified by PVB, and formed by high temperature die stamping. Connecting pipe and liquid outlet pipe are phenolic glass fibre pipes made by semi-dry rolling process. Impeller shaft sleeve is stick to pump shaft by phenolic mastic. All submerged components are assembled by phenolic mastic. Those in contact with medium are all no metal components, so as to ensure absolutely corrosion resistance. Featured by the outstanding performances of light weight, high strength, nondeforming, temperature and corrosion resistance, this product can be used partially instead of the precious metal of stainless steel containing molybdenum, titanium and titanium alloy for corrosion resistance purpose.
Widely used in the industries of chemical, petrochemical, refining, dyestuff, pesticide, pharmaceutical, rare earth and fertilizers, etc., this pump is an optimal choice to handle the corrosive medium in storage tank, like various non-oxidated acid (hydrochloric acid, thin sulfuric acid, formic acid, acetic acid and butyric acid) not containing solid particles, not easily crystallized, and temperature not over 100℃
