进口双级离心泵美国阿卡迪亚品牌

进口双级离心泵Product Description: It includes a first stage centrifugal pump composed of a centrifugal impeller and a centrifugal guide vane, a secondary regeneration pump composed of a regeneration pump impeller and a regeneration pump body, and a transfer diversion chamber connecting the first stage centrifugal pump and the secondary regeneration pump; The centrifugal impeller and the regeneration pump impeller are coaxially fixed on the pump shaft, and the two impellers are synchronously driven by the motor. With the help of the pressurization of the primary centrifugal pump, the gas content of the inlet fluid of the regeneration pump is effectively reduced, the inlet conditions of the secondary regeneration pump are improved, and the operation noise of the pump is reduced. At the same time, the organic combination of the primary centrifugal pump and the secondary regenerative pump realizes the complementary advantages of the two pumps, while retaining the compact overall structure of the pump and little change in volume compared with the conventional regenerative pump. characteristic: Vortex pump, friction pump or self-priming pump is a fluid machinery with large quantity and wide range,进口双级离心泵low energy efficiency and power. It first appeared in the 1920s. Regenerative pump is a special vane pump with radial blades or impeller with small inclination angle. Generally speaking, the efficiency of regeneration pump shall not exceed 40%. Although the efficiency is not high, the regenerative pump has simple structure, strong self-priming capacity and high head. It is widely used in various fields of the national economy, such as domestic water pressurization, air conditioning pump and solar water heater. Principle: ]The increase of liquid energy in the flow channel of the regeneration pump is realized by the conversion of low-quality kinetic energy to high-quality pressure energy. The liquid collides repeatedly between the flow channel and the impeller, so that a considerable part of kinetic energy is converted into heat energy and finally dissipated. This working characteristic of the regeneration pump determines that its efficiency cannot be very high. Compared with the centrifugal pump with the same power, the flow and efficiency of the regeneration pump are much smaller, but its head is significantly better than the former.进口双级离心泵 Moreover, most regeneration pumps are equipped with gas-liquid separation chamber and have good self-priming capacity. In contrast, centrifugal pump has higher hydraulic efficiency, larger flow and relatively low head. In addition, the blade top clearance between centrifugal pump impeller and volute is larger, so the operation noise of centrifugal pump is very low and often lower than that of motor
