KCB gear pumps are designed to have the highest efficiency near the rated operating point. If the KCB gear oil pump is running at a large flow operating point, its operating efficiency will drop rapidly. Under normal circumstances, after the same pump exceeds the rated point, the larger the flow rate, the smaller the efficiency, so under high flow conditions The operation is very uneconomical. The influence of long-term high-flow operation of KCB gear oil pump (1) The efficiency is reduced and the power consumption is increased. KCB gear pumps are designed to have the highest efficiency near the rated operating point. If the KCB gear oil pump is running at a large flow operating point, its operating efficiency will drop rapidly. Under normal circumstances, after the same pump exceeds the rated point, the larger the flow rate, the smaller the efficiency, so under high flow conditions Running is very uneconomical. Under normal circumstances, it is necessary to refit the appropriate high-efficiency large pump.
(2) The vibration noise increases, causing environmental pollution, damaging the pump components and affecting the service life of the pump. At the design operating point, the flow loss direction is consistent with the blade direction, the loss of flow, the impact loss, and the vortex loss are relatively small, close to zero. However, when the pump is working in a large flow area, similar to the small flow condition, Botaibang is deviated from the design point, causing the outflow loss, impact loss and vortex loss of the pump overcurrent component to be further increased. These losses are accompanied by a large amount of losses. Oily noise and mechanical vibration.
(3) Under normal circumstances, the larger the flow rate of the KCB gear oil pump, the greater the motor power required. When working in a large flow area, it may overload, burn out the motor or cause the circuit to trip protectively, and stop the pump.
(4) The radial force of the pump is increased, which deteriorates the force of the rotor of the pump. Since the pipeline KCB gear oil pump deviates from the design working point when working in the large flow area, the liquid flow velocity in the vortex chamber increases. However, according to the speed triangle analysis, the liquid outflow speed in the impeller is reduced, so that the liquid cannot merge and the impact is continuously increased. , generating radial force.
