The selection of gear pump
Gear pump are mainly gear, shaft, pump body, pump cover, bearing and shaft end seal, etc.Gear pump with double circular arc tooth sine curve.It is the most prominent advantage compared with involute gear tooth profile in gear meshing process there is no relative sliding, so the tooth surface abrasion, stable running, without fluid phenomenon, low noise, long life and high efficiency.The pump out of the bondage of traditional design, making the gear pump on the design, production and use has entered a new field.
Gear oil pump preheating is necessary, it can avoid the high temperature impact damage to part.When the pumping fluid recommended preheating temperature higher than 150 ℃.When using mechanical seal, gear oil pump should be informed within 30 ℃ preheat to operating temperature difference, in order to prevent the sealing surface damage.Clip model pump through steam preheating, heat transfer and electric heating ways.Viscosity is a fluid flow resistance, working condition of high viscosity of the first question is how to make the fluid in the pump.Gear oil pump must turn slowly so that the fluid into the holes between meshing tooth, the hole forming suction fluid in the suction pump.Clearance tight, with the gear oil pump seal, the better, the stronger the suction.
