三螺杆泵 水電站專(zhuān)用(yòng)螺杆泵3G85x6C2流量44立(lì)方

●3G三螺杆(gǎn)泵工作原理:

　　3G型三螺杆泵(bèng)是轉子型容積泵，适于輸送各(gè)種不含固體顆粒，無(wú)腐(fǔ)蝕性油類及類似油的(de)潤滑性液體(tǐ)、輸送液體粘(zhān)度2~760mm2/s，溫度不超過80℃,超過80℃可用(yòng)高溫泵(bèng)3GW型。3 g type is three screw pump rotor type positive displacement pump, is suitable for conveying various not containing solid particles, non-corrosive oil lubricity and similar oil liquid, conveying liquid viscosity was 2 to 760 / s, temperature not over 80℃, more than 80℃high temperature pump available 3 gw type.

   3G型三螺杆具有多種結(jié)構，一般小流量泵(bèng)襯套和泵體合(hé)為一個，可以卧式和立式安裝。進油口(kǒu)方向可相隔90°任(rèn)意安裝，軸封多數為機構密封。中等流量以上泵，襯套為一(yī)個單獨的零件(jiàn)固定于泵體内，螺杆軸端裝有平衡(héng)環以液力(lì)平衡其(qí)軸向力。一般結構(gòu)為卧式。進油口方向亦可以相隔90°任意安裝。改變泵體後可制成立(lì)式。軸封(fēng)根據情況有(yǒu)機械密封和軟填料(liào)密封兩種結構。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(bèng)軸伸支(zhī)承較(jiào)小，應由原(yuán)動機經彈性聯軸器直接驅動，不得用皮帶輪等會産生額外(wài)徑向力較大(dà)的傳動方式傳動(dòng)。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三螺杆泵輸送各種油類時應注意(yì)事項：When conveying various oil matters should be paid attention to:

   1、輸送40~150mm2/s的油類(lèi)最合适，允許按泵的最(zuì)高工作壓力(lì)使用。2、輸送40mm2/s以下的油類，為保證泵的流量及壽命應降(jiàng)壓使用。3、輸送150mm2/s以上的油類，且進油管道過長，彎頭過(guò)多(duō)，泵工作時如産生噪音或(huò)振動現象，則應考慮更換低一級轉速的電機運轉或縮短吸入(rù)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(sān)螺杆泵安裝要(yào)求:3 g type three-screw pump installation requirements:

   1、安裝前應檢查泵的油封是(shì)否良好，并檢查泵在運輸中是否損壞，可用手轉動聯軸器(qì)是否有卡勁現象(xiàng)，如有則應拆泵進行清洗(xǐ)，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、安裝泵的進油和排油(yóu)管道時，其管徑不得小于泵的進油和出(chū)油口口徑，進油管道不得過(guò)長，彎頭不得(dé)過多，否則(zé)将影響泵(bèng)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主(zhǔ)管線上，為(wéi)便于泵的啟動，在近(jìn)泵的排油管上必須安裝逆止閥。

3, when more than two head of pump installed in the e line, to facilitate pump start-up, in close to the oil drain pump must be installed on a non-return valve.

4、對于在(zài)較高溫度（指60℃以上）下(xià)輸送粘度大的油類（如：重(zhòng)油）的備用泵，必須是熱備(bèi)用泵，否則泵在低溫下啟(qǐ)動會造成(chéng)電機過載或泵(bèng)損壞。（建議在靠近泵(bèng)的排油管上的逆止閥旁，并聯安裝一(yī)個小回(huí)流閥，對備用泵可微啟回流閥，使泵緩慢逆轉(zhuǎn)，其逆轉速≤100轉/分，使部分熱油經(jīng)常流過泵内，達到泵(bèng)熱備用目的）。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(zhì)。将嚴重影響泵的運(yùn)轉和降低(dī)使用壽命，因此在泵安裝前，必(bì)須仔細(xì)清除進(jìn)油管内的焊渣，沙粒(lì)等雜(zá)質，并應在進油管道靠近泵處安裝(zhuāng)濾器，濾器網孔(kǒng)大小，可根(gēn)據工作情況及介質粘度确定。（一般可用40~80目網），過濾面積一般不得(dé)小于進油管橫(héng)截(jié)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(liàng)在泵進油和排油口處的螺紋孔上連接壓(yā)力表和真空表，以便(biàn)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(yǔ)泵的轉軸必須在(zài)同(tóng)一中心線上，可(kě)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)與泵的轉向必須一緻，嚴格禁止原動機(jī)驅動泵逆轉。電機接(jiē)線時，應先脫開電機(jī)與泵的(de)聯軸器，對電機作試(shì)運(yùn)轉。使其轉向(xiàng)與泵的轉向标志一緻。7, prime mover and the pump shaft must be in the e 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
