Operation skills of heat conduction oil pump
The heat conduction oil pump is an ideal hot oil circulation pump or a heat carrier transfer pump, and an ideal matching pump for heat exchange equipment. The support of the heat conduction oil pump adopts the structural form of double-end ball bearing support. The front end is lubricated with lubricating oil, the rear end is lubricated with grease, and there is an oil guide pipe in the middle to observe the sealing condition and recover the heat conduction oil at any time. The heat conduction oil pump adopts imported polytetrafluoroethylene (PTFE for short) as the lip seal, which makes a leap in sealing performance, which is 25 times more reliable than rubber seals, and has strong corrosion resistance.
How to operate the heat conduction oil pump safely and correctly? Always check the looseness of the anchor bolts, whether the temperature of the pump casing of the heat conduction oil pump is consistent with the inlet temperature, the fluctuation of the outlet pressure gauge and the vibration of the pump. Pay attention to whether there is any noise in the operation of the heat conduction oil pump. If an abnormal state is found, it should be dealt with in time.
The heat conduction oil pump is provided with a stuffing box at the front end, and the sealing performance is relatively reliable. At the same time, a mechanical sealing device is provided in the bearing seat, so a large amount of leakage cannot occur, and a small amount of leakage can be discharged through the leakage nozzle. Shutdown: cut off the power. Empty the liquid in the heat transfer oil pump, clean it, and periodically rotate the impeller 180 degrees to prevent shaft deformation until the oil pump is completely cooled.
The heat transmitted by the conveying medium to the pump cover and bearing of the heat transfer oil pump is dissipated by the surface of the pump cover and the bearing seat, so that the temperature of the bearing seat is adapted to the temperature of the shaft sealing performance. Therefore, when choosing the installation location of the heat transfer oil pump, the heat of the pump cover and bearing seat should be easy to diffuse the pipeline pump.
The heat conduction oil pump should not be operated continuously under low flow rate. If it must be operated under this condition, a bypass pipe should be installed at the outlet, and the flow rate should be above the above minimum value.
