Single-side water pump suction pump working principle and structure

The main inhalation of a single suction pump is mainly through the horizontal axis direction, spit out the upward diameter. As its range of use increases, it is important to understand the working principle of a single suction pump. The structure of the pump is a suspension type. When it is in service, it is not necessary to disassemble the inlet and outlet pipes to exit the rotor. The pump is connected to the motor through an ordinary flexible coupling or an extended flexible coupling. The pump shaft seal is sealed with a soft packing. Bearings for single row radial ball bearings, lubricated with oil. From the motor end, the pump rotates clockwise. Single-side water pump single suction pump working principle and structure When the single suction pump starts, the pump shaft driven impeller together for high-speed rotary motion, forcing the pre-filling liquid in the blade rotation, the role of inertial centrifugal force, the liquid from Impeller center for radial movement to the outer periphery. Liquid flows through the impeller in the process of gaining energy, static pressure can increase the flow rate increases. When the liquid leaves the impeller and enters the pump casing, it will decelerate due to the gradual enlargement of the flow passage in the shell. Some of the kinetic energy will be converted into static pressure energy and flow into the discharge pipe in the tangential direction finally. Therefore, the snail-shaped pump housing is not only a collection of components from the impeller out of the liquid, but also a transformable device. When the liquid thrown from the center of the impeller to the periphery at the same time, the center of the impeller to form a low pressure zone, the tank surface and the impeller center of the total potential difference under the action of the liquid was sucked into the impeller center. Depending on the continuous operation of the impeller, the liquid is continuously aspirated and discharged. The mechanical energy obtained by the liquid in the centrifugal pump ultimately appears as an increase in static pressure energy. The main components of a single suction pump is a high-speed moving impeller and a stationary snail-shaped pump housing. Generally contains four - 12 backward curved blade impeller fastened to the pump shaft, and with the pump shaft driven by the motor for high-speed rotation. As its scope of application continues to expand, we can expect more and more opportunities and challenges for single suction pumps in the future. We must do more to prepare for the challenges of the future. Related Articles: Centrifugal Pump Parameters Centrifugal Pump Features Analysis
