WRY-type heat pump operation flow A, WRY-type heat transfer pump boot preparation 1, clean up the site, unscrew the bearing screws, adding thermal oil for lubrication. 2, check whether the direction of motor rotation and pump rotation consistent. 3, hand-moving coupling pump should be flexible rotation. 4, before driving the use of the heat transfer oil filled pump to get rid of the pump air, this time spit outlet pipe gate valve should be closed. 5, the heat transfer oil delivered before driving uniform heating, preheating is the use of the heat transfer oil is continuously passed through the pump body. 6, preheat standard: pump shell temperature not lower than the inlet oil temperature 40 degrees, preheat speed of 50 degrees / hour, when driving preheating pump nut should be loosened side nut 0.3-0.5 mm, preheated Should be tightened. 7, before driving should check the foundation and bolt loose, the seal is normal. Second, WRY-type thermal oil pump boot 1, a comprehensive inspection of the preparatory work has been completed. 2, open a variety of instrument switch. 3, turn on the power, when the WRY-type heat transfer oil pump reaches the normal speed, and the instrument shows considerable pressure, gradually open the output valve on the pipeline, and adjusted to the need conditions. In the case of a closed gate valve on the output line, the pump must not work continuously for more than 3 minutes. 4, WRY-type heat transfer oil pump during initial operation, the production process equipment slowly heated to 100-130 degrees, and maintained at that temperature to continue running, dehydration degassing into the heat transfer oil in the water completely evaporated, only the equipment Heat to operating temperature. 5, 3-4 hours in the initial run, the equipment is heated to operating temperature after turning off the pump, check the pump shaft and motor shaft coupling coaxiality, pump shaft and motor shaft deviation should be controlled within the allowable range, the pump shaft Hand rotation should be lightweight and flexible rotation without vibration, if not meet the above requirements, should be re-adjusted. 6, the boot process, always pay attention to motor power readings and vibration conditions, the vibration value does not exceed 0.6 mm, if abnormal should be checked. 7, each ball bearing running 3000 hours, you must remove the clean with diesel, check for damage, if damaged, you must replace the new bearing. 8, by the impeller side of the ball bearing installation, the side of the dust cover to impeller installation, before driving into the thermal oil lubrication. 9, by the coupling side of the ball bearings, with complex calcium-based high-temperature grease, the bearing re-install, the dust-proof side also toward the impeller side installation, filling grease during installation. 10, 48 hours after the bearing is running, use a grease gun to inject grease into the pressure cap on the bearing cap. 11, not allowed to enter the pipe gate valve to regulate the flow, to avoid cavitation. 12, always check the looseness of the anchor bolts, pump housing temperature and inlet temperature are consistent with the export pressure gauge fluctuations and pump vibration. 13, pay attention to whether there is no noise pump operation, such as abnormal conditions found, should be promptly processed. Third, WRY-type thermal oil pump down 1, cut off the power. 2, the pump liquid emptying, cleaning and regular rotation of the impeller should be 180 degrees to prevent shaft deformation until the pump is completely cooled so far.
