●輸送皂角泵并(bìng)不能産生壓力，它(tā)隻是輸出流量。壓(ya)力低或無壓力❓，說(shuō)明輸送皂角(jiǎo)泵沒有吸入液體(ti)或洩漏嚴重。High viscosity gear pump does not generate pressure, it is only the output flow.Pressure is low or no pressure, high viscosity gear wheel pump don't inhale the liquid or leakage is serious.

　　電動(dong)機輸出功率偏小(xiǎo)、齒 輪泵排量選得(de)過大或壓力調得(dé)☂️過高🌐時，也會造成(chéng)壓力不足 當然，壓(yā)力表損壞或壓力(lì)表節😄流孔堵塞💁時(shi)也顯示不出壓力(li)，此時⛹🏻‍♀️可換裝一個(ge)新的壓力表檢查(chá)。Small motor output power, gear wheel pump capacity to choose too large or pressure too high, can cause stress Pressure gauge damage or pressure gauge orifice jams, of course, also could not show pressure, can change a new pressure gauge to check at this time.

　　如果确認泵無流(liú)量輸出，可能是由(you)于泵安裝有誤、泵(beng)㊙️的轉🐉向👈不對，或吸(xi)人側(進液口及吸(xī)液管道)堵塞、出口(kou)止回閥裝反或卡(ka)死了，也有可能是(shì)驅動軸斷裂了。If confirmed that no flow pump output, could be turned to the pumps due to pump installation is wrong, wrong, or suction side (liquid into the mouth and suck liquid pipeline jam, export check valve installed backwards, or card is dead, it is possible that the drive shaft fracture.
