[Asia pump network hearing] liquid ammonia pump in the use of axial force may occur when the problem, then how do we correct the axial force to eliminate its problems? Xiaobian give you introduce the correct elimination Liquid ammonia pump axial force, as follows: How to eliminate the axial force of liquid ammonia pump 1, the axial force causes: Because of the suction port pressure is also not completely symmetrical impeller on both sides of the fluid pressure Ranging, resulting in axial force. If the liquid pressure on both sides of the impeller does not account for the cross-sectional area of ​​the shaft and does not consider the influence of impeller rotation on the pressure distribution, the force acting on the impeller is the difference between the force received by the wheel and the force exerted by the wheel cover, Is the product of the difference between the outlet pressure and the inlet pressure and the area of ​​the impeller cover because the outlet pressure is always greater than the inlet pressure so when the liquid ammonia pump is rotated it must have a force acting on the rotor along the shaft and pointing in the inlet. 2, the problem of axial force: Unbalanced axial force will increase the liquid ammonia pump thrust bearing work load, unfavorable to the bearing, while the axial force to make the pump rotor to the suction port, causing vibration and may cause the impeller The friction of the mouth ring damaged the pump body. 3, liquid ammonia pump is generally used to balance the balance of impeller and the impeller installation, single-stage pump is generally open in the impeller balance hole, of course, the balance wheel mounted on the impeller disc way to balance the axial force. 4, although we are required to eliminate the axial force, but if completely eliminated will cause the rotor in the rotation instability, so in the design, will design a 30% of the amount of bearings to offset, which is why the liquid Ammonia pump non-driven end bearings are usually angular contact bearings, because it can be used to withstand large axial forces.
