Hot oil pump inlet pipe and with the analysis of the causes of air in the pump body

Time: 2016/5/21 19:41:01
Hot oil pump inlet pipe and pump body have the cause of the air
Some users not in front of the hot oil pump start pouring enough oil, sometimes look to fill the oil from vent overflow, turn the pump shaft to hand in the air but not fully discharge, causing a little residual air in the inlet pipe or the pump body.
Hot oil pump inlet pipe and has the reason of the air in the pump body
Contact with the hot oil pump inlet pipe of oil flat slope section of the application of more than 0.5% of the decline in reverse flow direction, connect one end of the hot oil pump imported as the highest, oil don't completely flat. If up, cock would survive the air inlet tube, reduces the tubing and vacuum degree in the hot oil pump, oil absorption.
Hot oil pump inlet pipe and has the reason of the air in the pump body
Hot oil pump packing for long-term use have wear or too loose, the packing caused a lot of oil spewing from the clearance between the pump shaft sleeve and packing, as a result, the external air from these longernal clearance longo the hot oil pump, oil extraction.
Hot oil pump inlet pipe and has the reason of the air in the pump body
Oil inlet pipe because of long-term potential, pipe wall corrosion holes, the oil level of hot oil pump work after falling, when the holes after the oil level, the air enters from the hole tubing within the DPP.
Hot oil pump inlet pipe and has the reason of the air in the pump body
Inlet pipe bend fractures, with hot oil pump inlet pipe jolong in small clearance, are likely to make the air entering longo the tubing.
