Pay attention to whether the heat conduction oil pump is running noisily. If the normal state is found, it should be dealt with in time. Shutdown: Cut off the power supply. Empty the liquid in the heat conduction oil pump, clean it, and rotate the impeller 180 degrees regularly to prevent shaft deformation until the oil pump is completely cooled.
Often check the loose ground of the anchor bolts, the pump shell temperature 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.
The heat conduction oil pump should not operate continuously under the design flow rate of less than 30%. If it must operate under this condition, the bypass pipe should be installed at the outlet, and the flow rate should reach the minimum value above.
Set with two ball bearings in the bearing seat, by heat conduction oil pump of the pump impeller side of a ball bearing with the transmission of heat conduction oil lubrication, by coupling side of a ball bearing with high temperature lubricating grease: after running 3000 hours, each ball bearing must be removed after use clean diesel, check whether the contact surface is damaged, if there are any damage, must change the new bearing. Do not use the gate valve on the input line to adjust the flow to avoid cavitation.
Heat transfer medium to the heat conduction oil pump cover and bearing, by the pump cover and the surface of the bearing seat heat dissipation, so that the temperature of the bearing seat to adapt to the temperature of the shaft sealing performance. Therefore, when selecting the installation position of the heat conduction oil pump, the heat of the pump cover and the bearing seat should be easy to spread and no heat storage phenomenon occurs.
The heat conduction oil pump pump shaft is provided with a packing box at the front end, and the sealing performance is more reliable. At the same time, a mechanical sealing device is arranged in the bearing seat, so a large number of leakage is impossible to appear, and a small amount of leakage can be discharged and received through the leakage pipe mouth. It is normal to have a small amount of leakage at the beginning of operation, and the leakage will be reduced or stopped after a certain period of time when the sealing surface is closed.
