1) The leaf wheels are rotated by the pump axis. For the fluids in the blades, the fluid has the effect of ionizing the heart, and the center of the impeller is thrown to the periphery. When the fluid reaches the periphery of the leaf wheel, the flow velocity is very high.

2) The pump shell is collected from the liquid thrown between the blades. These liquids flow in the shell in the shell and gradually expand the direction of the snar shell. Therefore, the role of the pump shell is not only to gather liquid, but it is also an energy conversion device.

3) Principles of liquid suction: Relying on the impeller high -speed rotation, forcing the liquid in the center of the impeller to be put aside at a very high speed, thereby forming a low pressure at the center of the impeller, and the liquid in the low slot is therefore continuously sucked. Qi binding phenomenon: If the centrifugal pump is filled with gas inside the shell, when the gase of the center of the lobe wheels is thrown, it cannot form a sufficiently large vacuum degree there, so that the liquid in the groove cannot be sucked.

This phenomenon is called qi binding. To prevent the occurrence of qi binding, before the start of the centrifugal pump, use foreign liquid to fill the space inside the pump shell. This step is called a pump. In order to prevent the liquid in the pump shell from flowing into the low -level slot due to gravity, the inverse valve (bottom valve) at the entrance of the pump suction pipeline is installed; Pump.

4) Installed the guide wheels per week, the energy conversion efficiency of the liquid in the pump is high. The guide wheel is a fixed rings of the blade located in the peripheral of the impeller.

The curved direction of this blade is the opposite of the bending direction of the impeller. Its curved angle is exactly the direction that the liquid is adapted from the direction of the liquid to the impeller. High efficiency of static pressure energy.

5) Eliminate axial thrust on the balance hole on the rear cover. The pressure of the liquid around the leaf wheels is high, and some of them will penetrate the back side of the rear sheet of the impeller, and the entrance of the front of the front side of the impelling is low pressure, so the axial thrust that pushes the impeller to the side of the pump entrance.

This is easy to cause wear at the contact with the impeller and the pump shell, and it will also vibrate in severe cases. The balance hole leaks a part of the high -pressure liquid to the low -pressure area to reduce the pressure difference between the front and back of the impeller. But this will also reduce the efficiency of the pump.

6) The shaft sealing device ensures the normal and efficient operation of the centrifugal pump. Fluor plastic centrifugal pumps work in the pump shaft rotation and the shell is not moving. If the cycle gap between them is not sealed or sealed, the external air will penetrate into the low -voltage area of the impeller center to reduce the flow and efficiency of the pump. In severe cases, the flow is zero -qi binding. Generally, mechanical sealing or filler can be used to achieve sealing between shafts.
