1, heat pump shaft pump set in the front stuffing box, sealing performance is more reliable. It is normal to have a small amount of leakage early in operation, and the leakage will decrease or stop after the sealing surface has run through a certain period of time. 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 conducting oil pump installation location, make the pump cover and bearing seat of the heat easily spread, do not appear the phenomenon of heat storage. 3, bearing set with two bearings, 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 new bearings. 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.
