A, ZWL self-priming non-clogging sewage pump Product Overview: ZWL type direct-coupled self-priming non-clogging sewage pump in repeated studies to develop a structure similar technology at home and abroad on the basis of the success of innovative products. The self-priming pump sets and non-clogging sewage in one, using external mixing type axial reflux and through the pump, impeller unique design, you can like the general self-priming pumps that do not need to install a foot valve and irrigation water, but also suction large solid particles and liquid contaminants long fiber can be widely used in municipal sewage works, Hetang farming, light industry, papermaking, textiles, food, chemical, electrical, fiber, pulp and mixed suspension etc chemical medium most ideal impurity pump. The pump uses direct-coupled structure compared with similar domestic products, with simple and compact structure, less vibration, self-priming performance, sewage capacity, high efficiency, easy maintenance, etc., is a national initiative in sewage pump series products. The technical performance indicators in the leading domestic and reached the international advanced level, have broad application market and development prospects. Two, ZWL self-priming non-clogging sewage pump Features: 1, compact structure. ZWL Direct self-priming sewage pump is a horizontal structure, pump body, good looks, small footprint, compared with the conventional pump, an area reduced by 30%. Such as the use of outdoor IP54 motors do not need pumping stations, it can be placed outdoors. 2, smooth running, low noise, high concentricity of components. Direct motor and pump, simplifying the intermediate structure, increasing the smooth running of the impeller excellent static and dynamic balance, vibration-free operation, low noise, extended bearing life and improve the environment. 3. Seal with quality mechanical seals, dynamic and static ring made of cemented carbide, wear no leakage, long service life. 4, the use of advanced hydraulic model, high efficiency, good performance characteristics. 5, easy to install and maintenance. Discharge piping not need to install check valves, suction line does not need to install a foot valve, thus simplifying the piping system, and improved working conditions. 6, the unique structure, self-priming performance, pump body before work just to ensure that there is quantitative priming can. Three, ZWL self-priming non-clogging sewage pump works: ZWL type direct-coupled self-priming non-clog sewage pumps, mainly consists of motor, shaft, retaining rings, mechanical seals, pump cover, pump body, impeller, sealing ring, turn on the water bolt, bottom cover, chassis, gas-liquid separator tube, the water took over, the fill valve, check valve films, imports formed to take over. Pump works: the pump body has a reservoir chamber, and through the loop-hole reflow holes above and below the working chamber communicates with the pump, constitutes an axial flow pump plus an outer recirculation system. After the pump stops working, the pump cavity has a volume of liquid storage. When the pump is started, the relevant authorities within the reservoir under the action of the impeller, carries air is thrown up, the liquid passes through the gas pipe grid back into the working chamber, the gas is discharged outside of the pump, so that a certain pump degree of vacuum to achieve the effect of self-absorption. Four, ZWL self-priming non-clogging sewage pump working conditions: 1, ambient humidity 50 ℃, medium temperature is 80 ℃ special requirements of up to 200 ℃. 2, medium PH value of 6-9 cast iron, stainless steel is 2-13. 3, medium weight of not more than 1240 kg / m3. 4, self-priming height must not exceed a predetermined value of 4.5 to 5.5 meters, a length of the suction pipe 10 meters. 5, through the ability of suspended particles having a diameter of 60% of the pump diameter, the fiber length of the pump diameter of 5 times.
