    3G型三螺杆具(jù)有多種結構，一般小流量泵襯(chèn)套和(hé)泵體合為一個，可以卧式和立式安裝。進油口方向可相隔90°任意安(ān)裝，軸(zhóu)封多數為機構密(mì)封。中等流量以上(shàng)泵，襯套為一個單獨的零件固(gù)定于泵體(tǐ)内，螺杆軸端裝有平衡環以液(yè)力平衡其軸向力。一般結構(gòu)為卧式。進油口方向亦可以相隔(gé)90°任意安裝。改變泵體後可制成(chéng)立式。軸封根據情況有機械(xiè)密封和軟填料密封兩(liǎng)種結構。Three screw with multiple structure of 3 g, general small flow pump bushings and pump body into one, can be installed in a horizontal and vertical.Oil inlet direction can be 90 ° apart any installation, most of the shaft sealing seal for your organization.The medium flow in pump, bushing as a separate component fixed in the pump body, screw shaft end is equipped with the gimbal ring to hydraulic balance the axial force.The general structure is horizontal.Inlet direction also can be 90 ° apart any installation.After the change of pump body can be made into vertical.Depending on the situation of the shaft sealing with mechanical seal and soft packing seal two structures.

    3G型三螺杆泵軸伸支承較小，應由(yóu)原動機經彈(dàn)性聯軸(zhóu)器直接驅(qū)動，不得用皮(pí)帶輪等會産(chǎn)生額外徑向力較大(dà)的傳動方式傳動。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(gǎn)泵輸送各種油類時應注意事項：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使用。2、輸送40mm2/s以下的油類，為(wéi)保證泵的流量及壽命應降壓使用(yòng)。3、輸送150mm2/s以上的油類，且進油管(guǎn)道(dào)過長(zhǎng)，彎頭(tóu)過多，泵工作時如産生噪音或振動現象，則應考慮(lǜ)更換低一級轉(zhuǎn)速的(de)電機運轉或縮短吸入管道(dào)，減(jiǎn)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(xíng)三螺杆泵安裝要求(qiú):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，可用手轉(zhuǎn)動聯軸器是否有卡勁現象，如(rú)有則應拆泵進行清洗，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、安裝泵的進(jìn)油和排(pái)油管道時，其管徑不得小于(yú)泵的進油和出油口口徑，進(jìn)油管道不得過長，彎頭不得過多，否則将影響泵的工作(zuò)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，為便于泵的啟動，在(zài)近泵的排油(yóu)管上必須安裝逆止閥。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)在較高溫度（指60℃以上）下輸送(sòng)粘度大的油類（如(rú)：重油）的備用泵，必須是熱備用泵，否(fǒu)則泵在低(dī)溫下啟動會造成電機過(guò)載或泵損壞。（建議在靠近(jìn)泵的排油(yóu)管上的逆止閥旁，并(bìng)聯安裝一(yī)個小回流閥，對備用泵可微啟回流(liú)閥，使泵緩慢逆轉，其逆轉速≤100轉/分(fèn)，使部分熱油經常流過泵(bèng)内(nèi)，達到泵熱備用(yòng)目(mù)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(nèi)含有機械雜質。将(jiāng)嚴重影響泵的運轉和降低使用(yòng)壽命，因此在泵安裝前，必須仔細清除進油管内的焊(hàn)渣，沙(shā)粒等雜質(zhì)，并應(yīng)在進油管(guǎn)道靠近泵處安(ān)裝濾器，濾(lǜ)器(qì)網孔大小，可根據工作情(qíng)況及介(jiè)質粘度确定。（一般可用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(jìn)油和排油口處的(de)螺紋孔上(shàng)連接壓力表和真空表，以便于觀察(chá)泵的運轉狀态。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、原動機與泵的轉軸必須在同一中心線上，可(kě)用直尺(chǐ)測隙規在聯軸器圓周上間隔90°處檢查。8、原動機與泵的轉向必須一緻，嚴格禁止原動機驅動泵逆轉(zhuǎn)。電機接線時，應先脫開電(diàn)機與泵的聯軸器，對電機作試運轉。使其轉向(xiàng)與泵(bèng)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型三螺杆泵的使用

　 　1、泵啟動前(qián)，必須全開進油和排油閘閥。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(yòng)長期封存(cún)的泵時，泵内無介(jiè)質，應在泵的進油腔灌注(zhù)适(shì)量輸送介質，避免泵幹啟動。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，應密切注意電流表，壓力表和(hé)真空表的數值(zhí)，超(chāo)出規定值時，應停泵找出原因後，再行啟動。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(liàng)大量增加時，對軟填料密(mì)封應壓緊填料壓蓋(gài)，對機(jī)械(xiè)密封應停泵修複後，再(zài)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(wēn)蒸汽清掃管線時，應避免高溫蒸汽(qì)通過泵内。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，應進行油封，并定期檢查油封情況，必(bì)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.●水電行業業績:
