●輸送皂角泵(bèng)并不能産(chǎn)生壓力，它(tā)隻是輸出流量(liàng)。壓力(lì)低或無壓(yā)力，說(shuō)明輸送皂(zào)角泵沒有吸入(rù)液體或洩漏嚴(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(diàn)動(dòng)機輸出(chū)功率(lǜ)偏小、齒 輪(lún)泵排(pái)量(liàng)選得過(guò)大或(huò)壓力調得(dé)過高(gāo)時，也會造(zào)成壓力不足 當(dāng)然，壓力(lì)表損壞(huài)或壓力表節流孔堵塞時也顯(xiǎn)示不(bú)出壓力，此(cǐ)時可換(huàn)裝(zhuāng)一個(gè)新的壓力(lì)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.

　　如果确認泵無流(liú)量輸(shū)出，可(kě)能是由(yóu)于泵安裝有誤(wù)、泵的轉(zhuǎn)向不對(duì)，或(huò)吸人側(進液口及吸(xī)液管道)堵塞、出口止回閥裝反(fǎn)或卡死了(le)，也有(yǒu)可能是驅動軸斷裂了。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.

　　輸(shū)送皂角泵(bèng)在轉(zhuǎn)速(sù)過低(dī)時(shí)會引(yǐn)起出液量不足(zú)，這種現象往往(wǎng)是由(yóu)于泵的驅(qū)動裝(zhuāng)置打滑或功率不足所緻(zhì)。此時(shí)應檢(jiǎn)查齒(chǐ) 輪泵的(de)實(shí)際轉(zhuǎn)速、泵與電動機(jī)的聯(lián)接及功率(lǜ)匹配(pèi)情(qíng)況等。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.

    1、工作壓力(lì)的選定1, select the work pressure

　　輸送皂(zào)角泵(bèng)額定的壓(yā)力是(shì)指泵連續(xù)工作時的最高(gāo)許用(yòng)壓力(lì)，而其(qí)工作(zuò)壓力則決定于外(wài)部負載(zǎi)，安裝和調(diào)試的壽命與其工作(zuò)壓力直接(jiē)相(xiàng)關(guān)。對于(yú)不頻繁工(gōng)作的(de)齒輪泵，其(qí)工作壓(yā)力可取為泵(bèng)的(de)額定壓(yā)力，考(kǎo)慮到産(chǎn)品(pǐn)質量不同，最好(hǎo)将額定(dìng)壓(yā)力降(jiàng)低20%～30%使用。對于經常工作于較高(gāo)壓力下的齒(chǐ)輪泵，其(qí)工作壓力應比泵的額定壓力(lì)低(dī)1～2個(gè)壓力級(jí)。石(shí)油化工設(shè)備常常是(shì)24小時(shí)連續(xù)運轉(zhuǎn)，這時泵的工作壓力(lì)應該(gāi)取得(dé)比額(é)定壓(yā)力低得多(duō)，且工作轉速也(yě)應該低于額定(dìng)轉速。如果高粘(zhān)度齒輪泵的工(gōng)作壓力(lì)調(diào)整過(guò)高，則會使齒(chǐ)輪泵在超(chāo)負(fù)荷下運行。high viscosity pump rated pressure refers to the maximum allowable pump continuous work pressure, and its working pressure is determined by the external load, installation and commissioning of life is directly related with work pressure.for not frequent work gear pump, the working pressure is desirable for the rated pressure of the pump, taking the quality into consideration, it is best to used pressure rated lower 20% ~ 30%.for often work under high pressure gear pump, the working pressure shall be lower than the rated pressure of the pump 1 ~ 2 pressure level.petrochemical equipment are often 24 hours of continuous operation, and at this time of the pump working pressure should be obtained was much lower than the rated pressure, and the work speed should be lower than the rated speed.if the high viscosity gear pump high pressure adjustment, will make the pump running under overload.
