Thermal oil pump maintenance

First, the transmission medium to the heat pump oil pump cover and bearing the heat from the pump cover and bearing surface cooling, so that the temperature of the bearing seat to adapt to the shaft sealing performance temperature.Therefore, the choice of conducting oil pump installation position, to So that the pump cover and bearing seat of the heat for easy diffusion, does not appear any heat accumulation .Second, hot pump shaft in the front end with a stuffing box, the sealing performance is more reliable, at the same time set in the bearing seat mechanical seal, so a lot of Leakage can not occur, and a small amount of leakage can leak through the leakage nozzle to receive a small amount of leakage in the early start running is normal, after a certain period of running on the seal surface leakage will be reduced or stopped. Two ball bearings are provided. One ball bearing on the pump impeller side of the HTF is lubricated with the heat transfer oil. One ball bearing on the coupling side is lubricated with high temperature grease. Each ball bearing is operated for 3000 hours After that, you must remove the clean with diesel oil, check the contact surface is damaged, if damaged, you must replace the bearings by the impeller-side ball bearing installation, the dust cover on the side to the leaves Installation, prior to start into the thermal oil lubrication.By the coupling side of the ball bearings, with complex calcium-based high temperature grease (ZFG-4), the bearing re-install, the dust cover side also toward the impeller side installation , Install the filling grease (about 1/2 ball bearing and shell space) .In the operation of the bearing 48 hours, use a grease gun to inject grease into the bearing cap filling grease.Four stop: Cut off the power. Conductive oil pump liquid venting, cleaning and the impeller should be rotated 180 degrees regularly to prevent the shaft deformation until the pump is completely cooled. Fifth, the heat pump should not be less than 30% of the design flow of continuous operation, if you must Conditions of operation, it should be installed in the bypass bypass pipe, and the flow to reach the above minimum 6. Sixth, often check the loose bolts of the ground conditions, heat pump shell temperature and inlet temperature are consistent, the outlet pressure gauge Fluctuations and vibration of the pump. Seven, attention to the operation of the heat pump has no noise, if the pilot state is found to be promptly processed. Heat transfer oil pump technology, high efficiency, long-term stable operation in the hot state no leakage, no additional cool down It has been widely used in the heating system of heating medium in China and has entered various industrial fields such as petroleum, chemical, rubber, plastics, pharmacy, textile, printing and dyeing, road building and food, etc. It is mainly used in Conveyor of weakly corrosive high temperature liquid without solid particles, temperature ≤370 ℃, is an ideal hot oil circulation pump.
