If the oil cooler is in use for a high-speed pump, can it do without the oil cooler?
It must be a hole in the oil cooler! The statement is not clear. It’s definitely not possible to stop the oil cooler from operating. If the ambient temperature is low in the north, it can run for a while depending on the rise in oil temperature.
During the pump testing, emulsification occurred and there were many small bubbles in the oil; it was suspected that the oil cooler was leaking. When the pump was tested again with the water circuit of the oil cooler shut off, no emulsification was observed, but numerous bubbles were still seen through the inspection port. The bubbles disappeared after the pump was stopped
If it continues to run, watering it for cooling outside the oil cooler and outside the gearbox will suffice.
That bubble is normal. Because oil generates bubbles under high-speed agitation and the compression from the speed increase gear. It will gradually disappear in a few hours.
Emulsification is irreversible. Based on your description, even if emulsification occurs, it cannot confirm a leak in the oil cooler. Suggestions: 1. Have experienced personnel collect the oil sample for testing to confirm emulsification; 2. Drain the waste oil through the drain hole. Then, depending on the situation, it is necessary to check and determine whether the emulsification is caused by high humidity or by oil leakage. 3. Take appropriate actions based on the inspection results, and clean the fuel tank before filling it with new fuel.
High-speed pumps inherently operate at high speeds, which generates a lot of heat due to mechanical wear; that’s why they are equipped with oil cooling systems to remove the heat produced by their operation. Without a cooling system, the temperature of its lubricating oil will keep rising, eventually leading to the destruction of the bearing in the pump gearbox.
If a high-speed pump cannot be cooled, it will burn out in minutes
