Speaking of spiral pump, many people may not concept, foggy. However, when it comes to sewage disposal, I think a little bit of common sense can be said about sludge treatment. In particular, almost everybody can talk about "blowdown" as the state has generously promoted the development of sewage treatment projects. However, it is not easy to say that sludge treatment is easy, and to understand what the relationship between screw centrifugal pumps and sludge treatment is. To this end, Asia Fluid Network Xiaobian particularly from the origin of the spiral centrifugal pump, spiral centrifugal pump technical characteristics and applications, and many other aspects to interpret, for you to uncover the spiral centrifugal pump how to display their secrets in the sludge treatment! Spiral Centrifugal Pump Origin of the Spiral Centrifugal Pump Originally from Switzerland, the spiral centrifugal pump was originally designed to help Peruvian fishing vessels to deliver live fish from fishing vessels. Thanks to the non-clogging and gentle conveying characteristics of screw centrifugal impellers, the pump The live fish can be delivered intact from the fishing net to the ship and then transported to the processing plant by ship. With the increasing development and improvement of products, spiral centrifugal pump applications gradually expanded. Spiral Centrifugal Pump Features Compared with ordinary common impurity pump and swirling pump, the structure of screw centrifugal pump has the following characteristics: A, no clogging performance: a large channel formed by the blade, plus the import-oriented and spiral propulsion The role of transport can contain large particles and fibrous material of the liquid, especially long-fiber objects can be passed smoothly. Conveying solid concentrations higher than other types of non-clogged pumps, compared with the traditional diameter of the traditional centrifugal impeller, the diameter can be much higher. B, soft conveying, non-destructive performance is good: the solid-liquid two-phase fluid is gradually pushed forward by the equilibrium spiral force and there is no sudden change in the flow direction, so the flow balance. In the sludge treatment process is particularly suitable for the transport of activated sludge, can maintain the characteristics of activated sludge. C, high efficiency and wide area D, the power curve is flat. E, with steep drop of the characteristic curve: changes in the head, the flow changes small, to ensure continuous and stable operation. F, the pump suction performance is good: the pump blade extends to the suction port, it can be pumped gas medium, inhalation of trace gases, the pump performance, vibration, noise basically unchanged, when the gas content of more than 40%, the pump Although it will produce intermittent vibration, but still able to run. G, high solid content. Spiral centrifugal pump applications are widely used in municipal sewage, sludge, petrochemicals, pulp wastewater, food processing and other fields. Visitors, do not know if you read the above content, whether the spiral centrifugal pump how to deal with sludge in the secret of mastering?
