     輸送各種油類時應注(zhù)意事項：When conveying various oil matters should be paid attention to:

    1、安裝前應檢查泵的油封是否良好，并檢查泵在(zài)運輸中是(shì)否損壞，可用手轉動聯軸器是否有卡勁現象，如有則應拆泵(bèng)進行清洗，修理和(hé)校正。2、安裝(zhuāng)泵的進油和排油管道時，其管徑不得小于(yú)泵的(de)進油和出油口口徑，進(jìn)油管道不得過長，彎頭不(bú)得過多，否則将影(yǐng)響(xiǎng)泵的工作狀态。3、當有兩台以上的泵安裝在同一條主管線上，為便于泵的啟動(dòng)，在近泵的排油管上必須(xū)安裝逆止閥。4、對于在較高溫度（指60℃以上）下輸送粘度大的油類（如：重油）的(de)備用泵，必須是熱備用泵(bèng)，否則泵在(zài)低溫下啟動會造成電機過載或泵損(sǔn)壞。（建議在靠近泵的排油管上的逆止閥旁，并聯安裝一個小回(huí)流閥，對備用泵可微啟回流閥，使泵緩慢逆轉，其逆轉速≤100轉/分，使部分(fèn)熱油經常流過泵内，達到泵熱備用目的）。5、輸(shū)送介質内(nèi)含有機械雜(zá)質。将嚴重影響泵的運轉和降低使用壽命，因此在(zài)泵安(ān)裝前，必須仔細清除進油管内的焊渣，沙粒等(děng)雜質，并(bìng)應在進油管道靠近(jìn)泵處安(ān)裝濾器，濾(lǜ)器網孔大小，可根據工作情況及介質粘度确定。（一般可用40~80目網(wǎng)），過濾面積一般不得小于進油管橫截面積的20倍。6、盡量在泵進油和排油口處的螺紋孔上連接壓力表(biǎo)和真空表，以便于觀(guān)察泵的運轉狀态。7、原動機與泵的轉軸必(bì)須在同一中心線上，可用直尺測隙規在(zài)聯軸器圓周上(shàng)間隔90°處檢(jiǎn)查。8、原動機與泵(bèng)的轉向必須一緻，嚴(yán)格禁止原動機驅動(dòng)泵逆轉。電機接線時(shí)，應先脫開電機與泵的聯(lián)軸器，對電機作試運轉。使(shǐ)其轉向與泵的(de)轉向标志一緻。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(xíng)三螺杆泵的使用1、泵啟動前，必須全開(kāi)進油和排油閘閥。2、首次(cì)啟動泵或再次使(shǐ)用長期封存的泵時，泵内無介質，應在泵的進(jìn)油腔灌注适量輸送介質(zhì)，避免泵幹(gàn)啟動。3、泵啟(qǐ)動後，應密切注意電流表，壓力表和(hé)真空表(biǎo)的數值，超出規定值時，應停泵找出原因後，再行啟動。4、軸封(fēng)處點滴洩露，應屬正常現(xiàn)象，當(dāng)洩露量大量增(zēng)加時，對軟填料密封應壓緊填料壓蓋，對(duì)機械(xiè)密封應停(tíng)泵修複後，再行啟動。5、用高溫蒸汽清掃管線時，應避(bì)免高(gāo)溫蒸汽通過泵(bèng)内。6、如果泵長期不(bú)工作時，應進行油封，并定期檢查油封情況，必要時重新油封。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.
