With the continuous use of single-stage centrifugal pumps in drainage, fire fighting and water supply areas, accelerating the promotion of single-stage centrifugal pumps has become the focus of many businesses. The working principle of single-stage centrifugal pumps is often the user Concerned about the focus, if businesses can better introduce the work of single-stage centrifugal pump, I believe will give users a single-stage centrifugal pump to increase confidence. Single-stage centrifugal pump Working principle Single-stage centrifugal pump includes pump body, pump cover, motor with output shaft, pump shaft, bearing seat, impeller, mechanical seal and machine seal gland installed in the pump body. Coupled with the motor shaft, the direction of rotation of the pump, from the drive side, clockwise rotation. It also includes a clutch-type coupling located between the motor output shaft and the pump shaft and a guide bearing mounted on the housing to assist in supporting the pump shaft. Before the single-stage centrifugal pump is started, the pump casing is filled with the liquid to be transported. After starting, the impeller rotates at a high speed by the shaft and the liquid between the blades must also rotate along with it. Under the action of centrifugal force, liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller to enter the scroll casing at a high speed. In the volute, the liquid due to the gradual expansion of the slowing down, but also part of the kinetic energy into static pressure, and finally to a higher pressure into the discharge pipe, to the required place. When the liquid flows from the impeller center to the outer edge, a certain vacuum is formed in the center of the impeller. Since the pressure above the liquid level in the sump is greater than the pressure at the inlet of the pump, the liquid is continuously pressed into the impeller. Visible, as long as the impeller constantly rotating, the liquid will be continuously inhaled and discharged. Single-stage centrifugal pump is a kind of high efficiency, energy saving, stable operation, safe and reliable pump equipment, at the same time it is easy to install, easy to maintain and also by the user's favorite. As China's industrial and agricultural industries such as drainage, fire water supply and other industries continue to increase demand, accelerate the development of single-stage centrifugal pumps become more urgent. Believe that as more experts and scholars to join the single-stage centrifugal pump will be better, single-stage centrifugal pump will work more in line with the needs of the market.
