Abstract

Изобретение относится к области устройств, предназначенных для перекачки жидкостей, и может быть использовано в промышленности, сельском хозяйстве и для бытовых нужд. Техническим результатом, достигаемым изобретением, является повышение создаваемого напора при сохранении КПД рабочего колеса центробежного насоса. Сущность изобретения заключается в том, что рабочее колесо центробежного насоса отличается тем, что величина угла между касательной к выходной кромке лопатки и касательной к окружности рабочего колеса находится в диапазоне от 40 до 90°, а форма лопаток описывается поверхностями второго порядка.The invention relates to the field of devices designed for pumping liquids, and can be used in industry, agriculture and for domestic needs. The technical result achieved by the invention is to increase the generated head while maintaining the efficiency of the impeller of the centrifugal pump. The essence of the invention lies in the fact that the impeller of a centrifugal pump differs in that the angle between the tangent to the output edge of the blade and the tangent to the circumference of the impeller is in the range from 40 to 90 °, and the shape of the blades is described by surfaces of the second order.
