Heat-conducting oil circulation pump daily use attention
When using high-temperature heat transfer oil pump should pay attention to the following aspects: 1, turn on the power, open the relevant instrument switch; When the pump reaches normal speed, and the instrument showed considerable pressure, gradually open the output valve on the pipeline and adjust to Need condition. In the case of output valve closed gate, the pump can not work continuously for more than 3 minutes; 2, just started running, the production process equipment slowly heated to 100-130 degrees, high temperature heat transfer oil pump and maintained at this temperature Continue to operate, dehydration degassing to the oil in the HTF completely evaporated before heating the equipment to the operating temperature; 3, the boot process, always pay attention to the motor power readings and vibration conditions, the vibration value of not more than 0.6 mm, if any Abnormal stop inspection; 4, 3-4 hours before operation, the equipment is heated to operating temperature, turn off the pump, check the coaxiality of the pump shaft and motor shaft coupling, pump shaft and motor shaft deviation should be controlled Within the allowable range, pump shaft rotation should be lightweight and flexible and vibration-free rotation, if the hot oil pump does not meet the above requirements, should be re-adjusted; 5, by the impeller-side ball bearing installation, high temperature thermal oil pump with dust cover Side toward the impeller installation, before driving into the thermal oil lubrication; by the coupling side of the ball bearings, with complex calcium-based high-temperature grease, self-priming centrifugal pump, the bearing re-install, the hot oil pump The dust-proof side also needs to be installed toward the impeller side and filled with grease during installation. 6, each ball bearing running 3000 hours, you must remove the clean with diesel, check for damage, if damaged, you must replace the new bearing.
