三(sān)螺杆泵 水電(diàn)站專用螺杆泵3G85x6C2流(liú)量44立方(fāng)

●3G三螺杆泵工作(zuò)原理:

　　3G型(xíng)三螺杆泵是轉子型容(róng)積泵，适于輸送各種不含固體顆粒，無(wú)腐蝕性油類及類似油的潤滑性(xìng)液體、輸送液體粘度2~760mm2/s，溫度不(bú)超過80℃,超過80℃可用高溫泵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(gǎn)具有多(duō)種結構，一般小流量泵襯套和泵體合為一個，可以卧式和(hé)立式安裝。進油口方(fāng)向可相隔(gé)90°任意安裝，軸封多(duō)數為機構密封。中(zhōng)等流量以上泵(bèng)，襯套為一個單獨(dú)的(de)零件固定于泵體内，螺杆軸端裝有平衡環以液力平衡其軸向力。一般結構為卧式。進油口方向亦可(kě)以相隔90°任意安裝。改變泵體(tǐ)後可制成立(lì)式。軸封根據情況有機械密(mì)封和軟(ruǎn)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(xíng)三螺杆泵軸(zhóu)伸支承較(jiào)小，應由原動機經彈性聯軸器直接驅動，不得用皮帶輪等會(huì)産生額(é)外(wài)徑向力較大的(de)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三螺杆泵輸(shū)送各種油類時應注意事項(xiàng)：When conveying various oil matters should be paid attention to:

   1、輸送40~150mm2/s的油類最合适(shì)，允許按泵的最高工作壓力使用。2、輸送40mm2/s以(yǐ)下的油類，為保證(zhèng)泵的流量及壽(shòu)命應降(jiàng)壓使用。3、輸送(sòng)150mm2/s以上的油類，且進油管道過(guò)長，彎頭過多(duō)，泵工作時如産生噪音或振動(dòng)現象，則應(yīng)考慮更換低一級轉速的(de)電機運轉或縮短吸入管道，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型三螺杆泵安裝要求:3 g type three-screw pump installation requirements:

   1、安裝前應(yīng)檢查泵的油封是否良(liáng)好，并檢查泵在運輸中是否損(sǔn)壞，可用手轉(zhuǎn)動聯軸器是否有卡勁現象，如有則應拆泵進行清洗，修理(lǐ)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(ān)裝泵的進油和排油管道時，其(qí)管徑不得小于(yú)泵的進油和出(chū)油(yóu)口口徑，進油管道(dào)不得過長，彎頭(tóu)不得過(guò)多，否則将影響泵(bèng)的工作狀(zhuàng)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(yī)條主(zhǔ)管線上，為便于泵的啟動，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(gāo)溫度（指(zhǐ)60℃以上）下輸送粘度(dù)大的油類（如：重油(yóu)）的備用(yòng)泵，必須是熱備用泵，否(fǒu)則泵在低溫下啟動會(huì)造成電機過載或(huò)泵損壞。（建議在靠近泵的排油管上的逆止(zhǐ)閥旁，并聯安裝一個小回流閥(fá)，對備用泵可微(wēi)啟回流閥，使泵(bèng)緩(huǎn)慢逆轉，其逆轉速(sù)≤100轉/分，使部分熱油經常流過泵内，達到泵熱備用目的）。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(yǒu)機械雜質。将嚴重影響泵的運轉和降低使用壽命，因此在泵安裝(zhuāng)前，必(bì)須仔細清除進油管内的(de)焊渣，沙粒等雜質，并應在進油管道靠近泵處(chù)安裝濾器(qì)，濾器網孔大小，可根據工作情況及介質粘度确定。（一般可用(yòng)40~80目網），過濾面積一般不得小于(yú)進油(yóu)管橫(héng)截面積的(de)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，以便于觀察泵(bèng)的(de)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(bèng)的轉軸必(bì)須在同一中心線上，可用直尺測(cè)隙(xì)規在(zài)聯軸器圓周(zhōu)上(shàng)間隔90°處檢(jiǎn)查。8、原動機與泵的轉向必須一緻，嚴格禁(jìn)止原動機(jī)驅動泵逆轉。電機接線時，應先脫開電機與(yǔ)泵的聯軸器，對電(diàn)機作試運轉。使其轉(zhuǎn)向與泵的轉向(xiàng)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
