Thermal oil pump is not oil and whether the relationship between the structure?

The structure of the heat pump is simple and easy to use and maintenance efficiency is also very high but also because the air-cooled centrifugal oil pump to mention the water and trouble. The principle of heat transfer oil pump is essentially a centrifugal pump, the pump inlet pipe and the pump body air or the existence of the end valve and impeller and other related issues, will affect the oil heat pump oil problem. When the Heat Transfer Oil pump inlet pipe and the pump body air, some users of high temperature heat pump oil pump is not filled with enough water before starting; sometimes it seems that irrigation water has overflowed from the vent hole, Heat transfer oil pump but did not turn the pump shaft air completely Discharge, resulting in a little air still remain in the inlet pipe or pump body. The water inlet pipe in contact with the pump should have a descending gradient of 0.5% or more in the horizontal section opposite to the direction of the water flow. Connect the end of the water pump to the highest level, not to the full level. If you tilt up, there will be trapped air inlet pipe, reducing the vacuum in the water pipes and pumps, affecting water absorption. Due to the long-term use, the packing of the heat-conducting oil pump is worn or the packing pressure is too loose, resulting in a large amount of water being ejected from the gap between the packing and the shaft sleeve of the pump. As a result, external air enters the pump from these gaps, affecting Lift water. Due to the long-term potential underwater pipe wall corrosion holes, water pump working continuously declining, when these holes exposed water, the air from the hole into the water pipe. There are cracks in the water inlet pipe, water inlet pipe and pump connection appear tiny gap, it is possible to make the air into the inlet pipe. There are other reasons other than the air obstructing the oil: for example, the bottom valve can not be opened. Usually because the pump is left on hold for too long, the bottom valve gasket of the heat transfer oil pump is stuck, and the bottom valve without the gasket may rust out. The bottom valve filter screen is clogged or the filter blockages in the submerged sludge in the bottom valve cause clogging. Serious impeller wear, impeller blades worn by long-term use, affecting the pump performance. Gate valve or check valve malfunction or blockage will result in reduced flow or even pumping oil. Leakage of heat-conducting oil outlet pipe will also affect the amount of oil.
