How to effectively improve the efficiency of chemical pump operation?
Work efficiency allows us to produce more results in the same time, so the working efficiency of mechanical products is very important, then how can we improve the operating efficiency of chemical pumps by reducing the volume loss?
(1) Reduce the leakage loss in the pump, improve the machining accuracy and assembly quality of the parts, reduce the radial clearance of the front disc of the balance disc and the radial clearance of the front and rear seal rings and the vane seal ring, and reduce the liquid in the pump. The pressure loss caused by leakage on the high pressure side to the low pressure side. For the impeller seal ring, the guide vane sleeve, the balance plate front throttle and other components, the material with higher hardness should be selected, and the heat treatment for improving the wear resistance should be performed.
(2) When starting the feed pump in cold state, the pump should be fully warmed according to the requirements of the regulations. If the warm pump is not sufficient, the pump body will easily generate a large thermal temperature difference, which will cause the bow to deform. At this time, the pump is easy to make the internal seal gap. Grinding, resulting in internal leakage and increased backflow volume loss.
(3) Carefully monitor the axial turbulence of the pump and the change of the discharge pressure after the balance disc during operation. During normal operation, the pressure after the balance disc is larger than the inlet pressure of the pump, and should be repaired in time to reduce leakage. Loss and increase the volumetric efficiency of the pump.
(4) When adjusting the load, it should be stable, avoid the large fluctuation of the water supply pressure, maintain the continuous and stable operation of the feed water pump, and reduce the axial movement of the pump to avoid the wear of the seal gap.
