     輸送(sòng)各種油類時應(yīng)注意(yì)事項：when conveying various oil matters should be paid attention to:

    1、安裝前應檢(jiǎn)查泵的油封是否良好，并(bìng)檢查(chá)泵在(zài)運(yùn)輸中是(shì)否損壞，可用手(shǒu)轉動聯軸器是(shì)否有卡勁(jìn)現象，如有則應拆泵(bèng)進行(háng)清洗，修理(lǐ)和校(xiào)正。2、安裝泵(bèng)的進油和(hé)排油管道時，其管徑(jìng)不得(dé)小于(yú)泵的進(jìn)油和出油口(kǒu)口徑(jìng)，進油(yóu)管道不得過(guò)長(zhǎng)，彎頭(tóu)不得過多，否則(zé)将影響(xiǎng)泵的工(gōng)作狀态。3、當(dāng)有兩台以(yǐ)上的(de)泵安(ān)裝在同一條主(zhǔ)管線(xiàn)上(shàng)，為便于(yú)泵的啟動，在近(jìn)泵的排油管上(shàng)必須(xū)安(ān)裝逆止閥。4、對于在(zài)較高溫度(dù)（指60℃以上）下輸送粘度(dù)大的(de)油類（如：重油）的(de)備用泵，必須是(shì)熱備用泵(bèng)，否則泵在(zài)低(dī)溫下啟(qǐ)動會(huì)造成(chéng)電機過載或(huò)泵損壞(huài)。（建議在靠近(jìn)泵(bèng)的排油管(guǎn)上的(de)逆止閥(fá)旁，并聯(lián)安裝一(yī)個小回(huí)流閥，對(duì)備(bèi)用泵(bèng)可微啟回(huí)流閥，使泵緩慢(màn)逆轉，其逆(nì)轉速(sù)≤100轉/分(fèn)，使部分熱(rè)油經常流(liú)過泵内，達(dá)到泵(bèng)熱(rè)備用目(mù)的）。5、輸送介質内(nèi)含有機械(xiè)雜質(zhì)。将嚴(yán)重影響泵的運轉和(hé)降低使用(yòng)壽命(mìng)，因此在泵安裝(zhuāng)前，必(bì)須仔細清除進(jìn)油管内的焊渣，沙粒等雜質，并(bìng)應在進油管道(dào)靠近泵處安裝(zhuāng)濾器，濾(lǜ)器網孔大小(xiǎo)，可根(gēn)據工(gōng)作情況及介質(zhì)粘度确定。（一般(bān)可用(yòng)40~80目網(wǎng)），過濾(lǜ)面積一般不得小于(yú)進油(yóu)管橫(héng)截面積的(de)20倍。6、盡(jìn)量在泵進油和(hé)排油口(kǒu)處的螺(luó)紋孔上(shàng)連接壓(yā)力表(biǎo)和真空表(biǎo)，以便于觀察泵(bèng)的運轉狀(zhuàng)态(tài)。7、原(yuán)動機與泵(bèng)的轉(zhuǎn)軸必須在同一(yī)中心線上，可用(yòng)直尺(chǐ)測隙規在(zài)聯軸器圓周上(shàng)間隔90°處檢查。8、原(yuán)動機(jī)與(yǔ)泵(bèng)的轉(zhuǎn)向必(bì)須一緻，嚴(yán)格禁止原動機(jī)驅動泵逆轉(zhuǎn)。電(diàn)機接線時，應先(xiān)脫開電機與泵(bèng)的聯軸(zhóu)器，對電機作試運轉。使(shǐ)其轉向與泵的轉向(xiàng)标(biāo)志一緻(zhì)。1, before installation should check whether the oil seal of the pump is good, and check the pump is damaged in transportation, turn the coupling usable hand card trouble phenomenon, if there is any should tear open pump for cleaning, repair and calibration.2, installation of pump suction and discharge of oil pipe, the pipe diameter shall not be less than the oil inlet of the pump and the oil outlet diameter, inlet pipe shall not be too long, elbow shall not too much, otherwise will affect the pump working condition.3, when more than two head of pump installed in the same line, to facilitate pump start-up, in close to the oil drain pump must be installed on a non-return valve.4, for under high temperature (above 60 ℃) conveying the viscosity of oil (such as: heavy oil) of the standby pump, it must be hot standby pump, otherwise the pump at low temperature can cause the damage of motor overload or pump.(suggest near the exhaust non-return valve on the tubing pump, a small return valve installed in parallel, differentiable and the backflow preventer to standby pump, the pump slow reversal, the reverse speed 100 r/min or less, often make some hot oil flows through the pump, to pump hot standby purposes).5, mechanical impurity is contained within the transmission medium.will seriously affect the operation and reduce the service life of pump, so before the pump installation, must be carefully clean up the feed tube welding slag, impurities such as grains of sand, and shall be installed in the inlet pipe near the pump filter, filter mesh size, is decided according to the working condition and medium viscosity.available (40 ~ 80 mesh net), filter area generally shall not be less than 20 times into the cross-sectional area of the tubing.6, as far as possible in the pump suction and discharge of oil on the threaded hole mouth connect pressure gauge and vacuum gauge, in order to observe the pump running state.7, prime mover and the pump shaft must be in the same center line, available ruler feeler gauge in the coupling of the circumference of a circle by 90 ° in check.8, steering engine and pump must be consistent, strictly prohibited prime motor driven pump reversal.electrical wiring, should first release coupling of motor and pump, a test run on the motor.the steering pump and steering sign agreement.

    3g型三(sān)螺(luó)杆泵的(de)使用(yòng)1、泵啟動前(qián)，必(bì)須全開進油和排(pái)油閘閥。2、首次啟動(dòng)泵(bèng)或再(zài)次使用(yòng)長期封(fēng)存的(de)泵時，泵内無介質(zhì)，應在泵(bèng)的進油腔灌注(zhù)适量輸送(sòng)介質(zhì)，避免泵(bèng)幹啟動(dòng)。3、泵啟動後，應密切注意電流表(biǎo)，壓力表和真(zhēn)空表的(de)數(shù)值，超出(chū)規定(dìng)值時(shí)，應停(tíng)泵找出原因後(hòu)，再行啟動。4、軸封(fēng)處點滴洩(xiè)露，應屬正常現象，當(dāng)洩露(lù)量大量增加時，對軟填料(liào)密封應壓緊填(tián)料壓(yā)蓋，對機(jī)械(xiè)密封應停(tíng)泵修(xiū)複後(hòu)，再行啟動(dòng)。5、用高溫蒸汽清(qīng)掃管線時，應避(bì)免高溫(wēn)蒸汽通(tōng)過泵内。6、如果泵(bèng)長期不(bú)工(gōng)作時，應進(jìn)行油封，并(bìng)定(dìng)期檢查油封(fēng)情況，必(bì)要時重(zhòng)新油封。the use of 3 g type three-screw pump 1, before starting the pump, oil inlet must be fully open and oil discharge gate valve.2, start the pump for the first time or again for a long time use of the pump, the pump inside without medium, should be in the inlet of the pump cavity perfusion amount transfer medium, avoid dry start pump.3, the pump starts, should pay close attention to current meter, pressure gauge and vacuum gauge value, beyond the specified value, should stop pump after find out, start again.4, shaft sealing drip leakage, should belong to the normal phenomenon, when the leak amount of increase, the soft packing seal should be compression packing gland, to pump mechanical seal shall be shutdown after repair, start again.5, with high temperature steam cleaning pipeline, should avoid high temperature steam through the pump.6, if the pump is not working for a long time, should carry on the oil seal, and regularly check oil seal, oil seal again if necessary.
