RY thermal oil pump work matters needing attention: 1, RY thermal oil pump shaft with a stuffing box in the front, the sealing function is more reliable, at the same time in the bearing seat is provided with a mechanical seal, so a lot of leakage can not be thrown, and a small amount The leak can drain through the spout to receive. A small amount of leakage is normal at the beginning of the operation, and the leakage will be reduced or stopped after running through the sealing surface for a certain period of time. 2, the transmission medium to the RY heat pump oil pump cover and bearing the heat from the pump cover and bearing surface cooling, so that the bearing temperature to adapt to the temperature of the shaft sealing function. Therefore, the choice of RY heat transfer oil pump installation position, to make the pump cover and bearing seat of the heat for easy proliferation, does not cause any heat accumulation phenomenon. 3, the bearing seat is provided with two ball bearings, by the RY heat pump oil pump impeller side of the ball bearing with the heat transfer oil lubrication, by the coupling side of a ball bearing is lubricated with high temperature grease: each Ball bearings running 3000 hours, you must remove the clean with diesel, check the contact surface is damaged, if damaged, you must replace the bearings. 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 grease into the pressure cup on the bearing cap. 4, not allowed to use the input valve on the gate to regulate the flow, to avoid gas anger. 5, RY heat transfer oil pump should not be less than 30% of the design flow continuous operation, if necessary under the premise of operation, it should be installed in the bypass bypass pipe, and to flow above the minimum. 6, often check the loose bolts anchor situation, RY heat pump oil pump casing temperature and inlet temperature are the same, the export pressure gauge fluctuations and pump vibration. 7, pay attention to RY conducting oil pump running without noise, if found normal state, should be promptly processed.
