     輸送(sòng)各種油類(lèi)時應注意事項：when conveying various oil matters should be paid attention to:

    1、安裝前(qián)應檢(jiǎn)查泵的油封是(shì)否良好，并(bìng)檢查(chá)泵在運輸中是(shì)否損壞，可用(yòng)手轉動聯軸器是(shì)否有卡勁(jìn)現象(xiàng)，如有則應拆泵進行清(qīng)洗(xǐ)，修理(lǐ)和校正。2、安裝泵(bèng)的進油(yóu)和(hé)排油(yóu)管道(dào)時(shí)，其管徑不得小于(yú)泵的(de)進油和出油口(kǒu)口徑，進(jìn)油(yóu)管道(dào)不得(dé)過長，彎頭(tóu)不得過(guò)多(duō)，否則(zé)将影(yǐng)響泵的工(gōng)作狀态。3、當有兩(liǎng)台以(yǐ)上的泵安(ān)裝在同一條主管線上，為便于(yú)泵的啟(qǐ)動，在近(jìn)泵的(de)排油管上(shàng)必須安裝逆(nì)止閥。4、對于(yú)在較高(gāo)溫度（指(zhǐ)60℃以上）下輸送(sòng)粘度大的油類（如：重(zhòng)油）的備用(yòng)泵(bèng)，必須是(shì)熱備用泵，否則泵在低溫下啟動會造成電機過載(zǎi)或泵損壞(huài)。（建議在(zài)靠近泵(bèng)的排(pái)油(yóu)管(guǎn)上的(de)逆止閥旁(páng)，并聯安裝(zhuāng)一個小回(huí)流閥(fá)，對(duì)備用泵(bèng)可微啟回(huí)流閥(fá)，使泵緩慢逆轉(zhuǎn)，其逆轉速(sù)≤100轉/分(fèn)，使部(bù)分熱油經常流過泵内，達(dá)到泵熱備用(yòng)目的）。5、輸送介(jiè)質内含有機械雜質(zhì)。将嚴重影響泵(bèng)的運轉和降低(dī)使用(yòng)壽命，因此(cǐ)在泵安裝前，必須仔(zǎi)細清除進油管内的焊渣(zhā)，沙粒(lì)等雜質，并(bìng)應在(zài)進(jìn)油(yóu)管道靠近泵(bèng)處安裝(zhuāng)濾器，濾(lǜ)器(qì)網孔(kǒng)大小，可根據工作情況及介質(zhì)粘度确定。（一般(bān)可用40~80目網(wǎng)），過濾(lǜ)面積(jī)一般不得(dé)小于(yú)進(jìn)油管橫截面積的20倍。6、盡(jìn)量在泵進(jìn)油和(hé)排油口處的螺(luó)紋孔上連接壓(yā)力表和真空表(biǎo)，以(yǐ)便(biàn)于觀(guān)察泵的運轉狀(zhuàng)态。7、原動機與泵(bèng)的轉(zhuǎn)軸必(bì)須在同一(yī)中心線(xiàn)上，可用(yòng)直(zhí)尺(chǐ)測(cè)隙規在(zài)聯軸器圓周上(shàng)間隔(gé)90°處檢(jiǎn)查。8、原動機與(yǔ)泵的轉(zhuǎn)向必(bì)須(xū)一緻，嚴(yán)格(gé)禁止原(yuán)動機(jī)驅動(dòng)泵逆轉。電機接線時(shí)，應先(xiān)脫開電(diàn)機(jī)與泵(bèng)的聯軸器，對電(diàn)機(jī)作(zuò)試運轉。使(shǐ)其轉向與泵的(de)轉向(xiàng)标志一緻(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型三螺(luó)杆(gǎn)泵的(de)使用1、泵啟動前(qián)，必須全開(kāi)進油(yóu)和排(pái)油(yóu)閘閥。2、首(shǒu)次啟動泵(bèng)或再次使用長期封(fēng)存的泵(bèng)時，泵内(nèi)無介(jiè)質，應在泵(bèng)的進油腔灌(guàn)注(zhù)适量輸送介質，避免泵幹(gàn)啟動(dòng)。3、泵啟動後，應密(mì)切注(zhù)意電(diàn)流表(biǎo)，壓力表和真空(kōng)表的數值，超出(chū)規定(dìng)值(zhí)時，應停(tíng)泵找出(chū)原(yuán)因後(hòu)，再行啟動。4、軸封(fēng)處點滴洩露，應屬正(zhèng)常(cháng)現(xiàn)象，當(dāng)洩露量大量增加時(shí)，對(duì)軟(ruǎn)填料(liào)密封應壓緊填(tián)料壓蓋，對機械密封應(yīng)停泵修(xiū)複後，再(zài)行啟動(dòng)。5、用高(gāo)溫(wēn)蒸汽清(qīng)掃管線(xiàn)時，應避(bì)免高溫蒸汽通(tōng)過泵内。6、如果泵長期不工(gōng)作時(shí)，應進行(háng)油封，并(bìng)定期檢查(chá)油封(fēng)情況，必要時重(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.
