The front end of the pump shaft of the heat-conducting oil pump is provided with a stuffing box, the sealing performance is more reliable, and the mechanical seal device is arranged in the bearing seat. Therefore, a large number of leaks can not occur, and a small amount of leaks can be discharged through the leaky mouth to receive. 1, a small amount of leakage in the early start of operation is normal, after a certain period of running on the seal surface leakage will be reduced or stopped. 2, the transmission medium to heat pump oil pump cover and bearing the heat from the pump cover and bearing surface cooling, the temperature of the bearing seat to adapt to the shaft sealing performance temperature. Therefore, the choice of heat transfer oil pump installation location, make the pump cover and bearing seat of the heat for easy proliferation, does not appear any heat storage. 3, the bearing seat is provided with two ball bearings, by the heat pump pump impeller side of a ball bearing with the heat transfer oil lubrication, by the coupling side of a ball bearing is lubricated with high temperature grease: Each ball Bearing 3000 hours after operation, you must remove the clean with diesel, check the contact surface is damaged, if damaged, you must replace the new bearing. When mounted on the impeller-side ball bearing, the dust-proof cover must be mounted on the side facing the impeller and lubricated with heat-conducting oil before starting up. On the coupling side of the ball bearings, the use of complex calcium-based high-temperature grease (ZFG-4), the re-install the bearing, with dust cover side also toward the impeller side installation, install grease (about 1 / 2 ball bearing and housing space). After 48 hours of operation, use a grease gun to inject replenishment grease into the pressure cup on the bearing cap. 4, not allowed to enter the pipe gate valve to regulate the flow, to avoid cavitation. 5, the heat transfer oil pump should not be less than 30% of the continuous operation under the design flow, if you must operate under the conditions, it should be installed in the bypass bypass pipe exports, and to flow above the minimum. 6, often check the loose bolts anchor situation, heat pump oil pump casing temperature and inlet temperature are the same, the export pressure gauge fluctuations and pump vibration. 7, pay attention to the existence of noise conduction heat pump operation, such as the pilot state was found to be timely manner. 8, downtime: cut off the power. The heat transfer oil pump liquid venting, cleaning and should regularly rotate the impeller 180 degrees to prevent shaft deformation until the pump is completely cooled so far.
