Common faults and troubleshooting methods of air-cooled high temperature
heat conduction oil pump.
1. The installation position of the heat conduction oil pump is too high from the oil surface, especially when the pump speed is reduced, the air is inhaled because the necessary vacuum of the pump suction cavity can not be guaranteed. At this time, the relative height of the pump and the oil surface should be adjusted to meet the specified requirements.
2. The oil absorption filter is blocked by dirt or its capacity is too small, which increases the oil absorption resistance and inhales air. In addition, the larger caliber of oil inlet and outlet may also bring air. At this point, you can clean the oil filter, or select a larger capacity and appropriate inlet and outlet diameter. In this way, the high-temperature heat conduction oil pump can not only prevent the inhalation of air, but also prevent noise.
3. If the oil quantity in the oil tank of the heat conduction oil pump is not enough, or if the oil suction pipe mouth is not inserted below the oil surface, the pump will inhale air, and the oil should be replenished to the oil mark line at this time; if the oil surface is exposed at the oil return pipe mouth, sometimes the air will be pumped back into the system because of the instantaneous negative pressure in the system, so the oil return pipe mouth should generally be inserted below the oil level.
4. The high temperature heat conduction oil pump generally uses the skeleton oil seal to seal the pump shaft. If the spring of the clamping lip falls off, or the oil seal is installed upside down, or the lip is pulled or aged, the back end of the oil seal will often be in a state of negative pressure and inhale air, and the new oil seal can be replaced.
5. Inhaling air is a common fault of high temperature heat conduction oil pump.
