Thus the centrifugal force is generated, under the action of centrifugal force, the liquid is dumped along the Blade Runner to the impeller outlet, and the liquid is collected and fed into the discharge tube through the worm shell. The liquid obtains energy from the impeller, increasing the pressure energy and speed energy, and relies on this energy to transport the liquid to the place of work. When an impeller does not allow the liquid to obtain sufficient energy, multiple impellers can be used in series or in parallel to work on the fluid. At the same time that the liquid is dumped to the impeller outlet, a low pressure is formed at the center of the impeller Inlet, and the pressure difference is generated between the liquid in the suction tank and the center of the impeller, and the liquid in the suction tank is continuously operated into the impeller under the action of this pressure difference. In this way, the impeller in the rotation process, one side of the constant liquid, while constantly giving the liquid with a certain amount of energy, the liquid discharge, so that the centrifugal pump work continuously. The medium-open pump is mainly composed of pump body, pump cover, sealing ring and rotor parts. Rotor parts are mainly composed of shafts and impeller mounted on the shaft, impeller retaining sleeve.

When the open pump reaches full speed operation, it is necessary to carefully check: (1) Pay attention to the pump import and export pressure, with the export gate valve adjustment so that its pressure control in the specified range. (2) Whether the bearing is overheating, the ideal temperature for bearing operation is 40~60℃, and the temperature rise does not exceed 35 ℃. If the temperature is stable and does not rise again, it may be slightly above the above range, but more than 80 ℃ must not be allowed. If more than 80 ℃, the bearing body shall be fitted with cooling water. Filler leakage water is dripping appropriate (about 30 drops per minute). After the pump starts with a wrench to adjust the filler cover nut tightening to adjust the leakage amount, in order to meet the leakage requirements. (4) Keep track of the operation on a regular basis. Pipeline Installation Steps: (1) After the installation of the equipment, joints, discharge pipes and valves, do not use the pump as a pipe and valve support, require adequate attention to make the pipe and valve weight and excessive tightening force, etc. do not affect the pump body. Installation accessories should also be taken care to avoid allowing the pump to withstand any external force. To reduce head loss.
