75KW 1500 M3/Hr 16 Inch 400HW-7 Mixed Flow Pump Use And Maintenance
(1)Often check the bearing’s temperature rise, which should not be over the ambient one by 35℃ generally and by 75℃ to the utmost extent.
(2)Often check if the bolts get loose due to vibration.
(3)When the bearing uses thin oil for lubricating, often check and control the oil level with the bearing body in between two marking lines on the oil leveler rod; and when it uses dry oil (lubricating grease), supplement a proper amount of oil in a period ic time by means of removing both front and rear covers for model 150~350HW pump and the oil cup for model 400~800HW pump.
(4)Drain out the water remained in both pump and pipeline after stop in case of winter.
(5)Adjust the packing properly to have the liquid intermittently leak in drops from the packing gland. Too tight packing will cause the shaft heated and the power increased while too loose will cause excessive liquid leak and a lowered efficiency.
(6)Pay attention to the power to see if it is suddenly enlarged or lowered and if the flow is suddenly reduced, stop the pump to troubleshoot if it is.
(7)Pay attention to both frictional and collided sounds which may occur during the pump movement. In case of friction between both pump cover and impeller, add paper pad in between both pump cover and casing. The applicable interval in the actual use is 0.3~0.7mm.
(8)Check if there is air which leaks from the water-in pipeline.
(9)Replace the lubricating oil or grease after 3000h work of the pump or in half a year and then once every 1000h or every year.
(10)In case of direct link between both pump and motor, have the axial lines of both on a same straight line.
