I. Product Overview:
ZWL type direct-coupled self-priming non-clogging sewage pump is a novel structure developed on the basis of repeated research on similar technologies at home and abroad. The pump integrates self-priming and non-blocking sewage discharge, adopts axial recirculation and external mixing, and through the unique design of the pump body and impeller flow passage, it can be installed like a general self-priming pump without installing a bottom valve and irrigation water. It can also absorb and contain large particle solids and long fiber impurity liquids, and can be widely used in municipal sewage engineering, river pond culture, light industry, papermaking, textile, food, chemical, electric industry, fiber, slurry and hybrid suspension. The ideal impurity pump.
The pump adopts direct-connected structure, compared with domestic similar products, it has the characteristics of simple and compact structure, less vibration, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, convenient use and maintenance, etc. The first in China. The technical performance indicators are leading domestically, reaching the international advanced level, with broad application market and development prospects.
Second, product features:
1, the ambient humidity of 50 ° C, the medium temperature of 80 ° C special requirements up to 200 ° C.
2. The medium PH value is 6-9 for cast iron and 2-13 for stainless steel.
3. The medium weight does not exceed 1240 kg/m3.
4. The self-priming height should not exceed the specified value of 4.5-5.5 meters, and the length of the suction pipe is 10 meters.
5. The capacity of the suspended particles is 60% of the pump diameter, and the fiber length is 5 times of the pump diameter.
Three, technical parameters:
Flow rate: 8~800m3/h;
Head: 15-80m;
