Reasons for the air in the inlet pipe and the pump body of the ry heat transfer oil pump. Cause 1: Some users are not filled with enough oil before the ry heat transfer oil pump starts. Sometimes it seems that the oil has overflowed from the vent hole, but the pump shaft is not turned to the air. Completely discharged, causing a little air to remain in the oil inlet pipe or pump body. ry heat transfer oil pump inlet pipe and pump body have air analysis reasons. Some users do not fill enough oil before the ry heat transfer oil pump starts, sometimes it seems to fill the oil The air has overflowed from the venting hole, but the air is not completely discharged from the pump shaft, so that a little air remains in the inlet pipe or the pump body.
The second reason is that the oil level of the inlet pipe that is in contact with the ry heat transfer oil pump applies a downward slope of 0.5% or more to the oil flow direction, and the end of the inlet of the ry heat transfer oil pump is the highest, and the oil level is not completely flat. If it is lifted up, air will remain in the inlet pipe, which will reduce the vacuum in the oil pipe and ry heat transfer oil pump, affecting oil absorption.
The reason is that the filler of the three ry heat transfer oil pump has been worn out due to long-term use or the packing is too loose. Botaibang caused a large amount of oil to be ejected from the gap between the packing and the pump shaft bushing. As a result, external air enters the gap from these gaps. The inside of the heat transfer oil pump affects the oil extraction.
The reason is that the four inlet pipes have holes due to long-term potential oil corrosion, and the oil surface of the ry heat transfer oil pump is continuously lowered. When these holes are exposed to the oil surface, the air enters the oil inlet pipe from the holes.
The reason is that there is a crack at the elbow of the inlet pipe, and a slight gap occurs between the inlet pipe and the ry heat transfer oil pump, which may cause air to enter the inlet pipe.
