●輸送皂角泵并(bìng)不能産(chǎn)生壓力(lì)，它(tā)隻是(shì)輸出流量。壓力(lì)低或無(wú)壓(yā)力，說明輸送皂(zào)角泵沒(méi)有吸入液體或(huò)洩漏嚴(yán)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(dòng)機輸出(chū)功率偏小、齒 輪(lún)泵排量選得過大或壓力調得(dé)過高時(shí)，也會造(zào)成壓力不(bú)足 當(dāng)然，壓力表(biǎo)損壞(huài)或壓力表節流(liú)孔堵塞時(shí)也顯示不出(chū)壓力，此(cǐ)時可換(huàn)裝一(yī)個(gè)新的(de)壓力表檢(jiǎn)查。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(guǒ)确認泵(bèng)無流(liú)量輸出，可(kě)能是由于(yú)泵安(ān)裝有誤、泵的(de)轉(zhuǎn)向不對，或吸人側(進(jìn)液口及吸(xī)液管道(dào))堵(dǔ)塞、出(chū)口止(zhǐ)回閥(fá)裝反(fǎn)或卡(kǎ)死了，也有可能是驅動軸(zhóu)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.

　　輸(shū)送皂角(jiǎo)泵(bèng)在轉(zhuǎn)速過(guò)低時會引(yǐn)起出液(yè)量不足，這種現象(xiàng)往往(wǎng)是由于(yú)泵的驅(qū)動裝置(zhì)打滑或(huò)功率不(bú)足所緻(zhì)。此時應檢查齒(chǐ) 輪泵的實際轉速、泵與(yǔ)電動機(jī)的聯接及功率(lǜ)匹配情況(kuàng)等。high viscosity pump in low speed can cause insufficient quantity of produced liquid, this phenomenon is often due to the slippage of the pump drive or insufficient power.check the gear wheel pump at this time of the actual speed, pump and motor connection and power matching, etc.
