    3G型(xíng)三螺杆泵軸伸支承較小(xiǎo)，應由(yóu)原動機經彈性聯軸(zhóu)器直接驅(qū)動，不得用皮帶輪等會産生額外徑向力較大的傳(chuán)動(dòng)方式傳動。3 g type three-screw pump shaft and bearing is small, should be driven by a prime mover directly by the elastic coupling, shall not be used pulley will produce additional radial force large transmission way.

　　●3G三螺杆泵輸送各種(zhǒng)油類時應注意事(shì)項：When conveying various oil matters should be paid attention to:

    1、輸(shū)送40~150mm2/s的油類最合适，允許按泵的最高工作壓力(lì)使用。2、輸送40mm2/s以下的油類(lèi)，為保證(zhèng)泵的流量及壽(shòu)命應(yīng)降壓使用(yòng)。3、輸送150mm2/s以上的油類，且進油管道(dào)過長，彎頭過多，泵工作(zuò)時如産生噪音或振動(dòng)現象，則應考慮(lǜ)更換(huàn)低一級轉(zhuǎn)速的電機運轉或縮短吸入管道，減少彎頭。1, delivery was 40 ~ 150 / s best oils, permitted to use according to the maximum working pressure of pump.2, transmission oil, under 40 was/s in order to ensure the pump flow and life should be used antihypertensive.3, transmission of more than 150 was/s oils, and the oil inlet pipe is too long, too much bend, such as noise or vibration phenomenon when the pump work, should consider to replace the low level of rotational speed of motor operation or shorten the suction pipe, reducing elbow.

　　 ●3G型三螺杆泵安裝要求:3 g type three-screw pump installation requirements:

     1、安裝前應檢查泵的油封是否良好，并檢(jiǎn)查泵在運輸中是否損壞，可用(yòng)手轉(zhuǎn)動聯(lián)軸器是否有卡勁現象，如有(yǒu)則應拆泵進(jìn)行清洗，修理和校正。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、安裝(zhuāng)泵的進油和排油(yóu)管道時，其管徑不(bú)得小于(yú)泵的進油和出油口口徑，進油管道不得過長，彎頭不得過多，否則将影響泵的工作狀态。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、當有兩台以上的泵安裝在同一條(tiáo)主管線上(shàng)，為便于泵的啟動，在近泵的排油管上必須安裝逆(nì)止閥。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、對于(yú)在較高溫(wēn)度（指60℃以上(shàng)）下輸送粘度大的油類（如：重油(yóu)）的備用泵，必須是熱備用泵，否則泵在低溫下啟(qǐ)動會造成電(diàn)機過載或泵損壞。（建議(yì)在靠近泵的排油(yóu)管上的逆止閥旁，并聯安裝一個小回流閥，對(duì)備用(yòng)泵可微啟回流(liú)閥，使(shǐ)泵緩慢逆轉，其逆轉(zhuǎn)速≤100轉/分，使部分(fèn)熱油經常流過泵内，達到泵熱備用(yòng)目的）。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、輸送介質内含有機械雜質。将嚴重影響泵的(de)運轉和降低使用壽命，因此在泵安裝前(qián)，必須仔細清除進油管内的焊渣，沙粒等雜質，并應在進油管道靠近(jìn)泵處安裝濾器，濾(lǜ)器網孔大小，可根據工作情況及介質粘度确定。（一般可(kě)用40~80目網），過濾面積一般不得小于進油管橫截面積的20倍。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、盡量在泵進油和排油口處的螺紋孔上連接壓力表和真空表，以(yǐ)便于觀察(chá)泵的運轉(zhuǎn)狀态。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、原動機與泵的(de)轉軸必須在同一中心線上，可用直尺測隙規在聯軸器圓周上(shàng)間隔90°處檢查。8、原動機(jī)與泵的轉向必須(xū)一緻，嚴格禁止原動機驅動泵逆轉。電機接線時，應先脫開電(diàn)機與泵的聯軸器，對電機作(zuò)試運轉。使其轉向與泵的轉向标志一緻。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(bì)須(xū)全開進油和(hé)排油閘閥。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、首次啟動泵或再次使用長期封存的泵時(shí)，泵内無介質(zhì)，應在泵的進油腔灌(guàn)注适量輸送介質，避(bì)免泵幹啟動(dòng)。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、泵啟動後，應密切注意電流(liú)表，壓力表和真空表的(de)數值，超出規定值時，應停(tíng)泵找出原因後，再(zài)行(háng)啟(qǐ)動。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、軸封處點滴洩露，應屬正常現象，當洩露量大量增加時，對軟填料(liào)密(mì)封應壓緊填(tián)料壓蓋(gài)，對機(jī)械密封應停泵修複後，再行啟動。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、用高溫蒸汽清掃管線時，應避免高溫蒸汽通過泵(bèng)内。5, with high temperature steam cleaning pipeline, should avoid high temperature steam through the pump.6、如果泵長期不工作時，應(yīng)進行油封，并定期檢查油封情況，必要時重新油封。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.●水電行業(yè)業績(jì):
