What is the main reason for the noise of heat transfer oil pumps?

The main cause of the noise of the heat transfer oil pump is due to bearing damage or cavitation due to high temperature in the circulation of the heat transfer oil pump and vibration caused by the unstable support of the heat transfer oil pump.

Due to the long-term contact operation of the heat transfer oil pump, the user does not change the oil in the bearing room frequently during use. The hot water pump causes the bearings to run for a long time at high speed under poor lubrication conditions, resulting in damage to the heat transfer oil pump bearings, which causes the heat transfer oil pump to generate noise. The heat transfer oil pump should be regularly maintained in daily production, cleaned, and the engine oil lubricated in the bearing chamber should be replaced in a timely manner. Once the heat transfer oil pump is found to be damaged, the bearing should be replaced in time to avoid damage to other parts of the pump.

In addition, newly installed customers often use the oil temperature rise too fast or the oil temperature rises too high for the first time when using a heat transfer oil pump. This will cause the heat-conducting oil to generate gas in the pipeline, and these gases will explode instantly when passing through the heat-conducting oil pump during the conveying cycle of the heat-conducting oil pump, so that the heat-conducting oil pump generates noise.

Should the heat transfer oil pump be used for the first time, the oil temperature should be gradually raised and the heat transfer oil pump should be started at the same time, and the pipeline exhaust valve should be opened successively to exhaust the gas in the pipeline and then use the heat transfer oil pump formally. Another is that the heat transfer oil pump has no support points on the inlet and outlet pipes during installation, or the support points are not stable, causing the heat transfer oil pump to generate huge pipeline resonance during use, so it will generate noise. The support of the pipeline should be stabilized in time.
