●3G三螺桿泵工作原理:

　　3G型三螺桿泵是轉子型容積泵，適于輸送各種不含固體顆粒，無腐蝕性油類及類似油的潤滑性液體、輸送液體粘度2~760mm2/s，溫度不超過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型三螺桿具有多種結構，一般小流量泵襯套和泵體合為一個，可以臥式和立式安裝。進油口方向可相隔90°任意安裝，軸封多數為機構密封。中等流量以上泵，襯套為一個單獨的零件固定于泵體內，螺桿軸端裝有平衡環(huán)以液力平衡其軸向力。一般結構為臥式。進油口方向亦可以相隔90°任意安裝。改變泵體后可制成立式。軸封根據情況有機械密封和軟填料密封兩種結構。

???3G型三螺桿泵軸伸支承較小，應由原動機經彈性聯(lián)軸器直接驅動，不得用皮帶輪等會產生額外徑向力較大的傳動方式傳動。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三螺桿泵輸送各種油類時應注意事項：When conveying various oil matters should be paid attention to:

???1、輸送40~150mm2/s的油類 合適，允許按泵的 高工作壓力使用。2、輸送40mm2/s以下的油類，為保證泵的流量及壽命應降壓使用。3、輸送150mm2/s以上的油類，且進油管道過長，彎頭過多，泵工作時如產生噪音或振動現(xiàn)象，則應考慮更換低一級轉速的電機運轉或縮短吸入管道，減少彎頭。

?●3G型三螺桿泵安裝要求:3 g type three-screw pump installation requirements:

???1、安裝前應檢查泵的油封是否良好，并檢查泵在運輸中是否損壞，可用手轉動聯(lián)軸器是否有卡勁現(xiàn)象，如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、安裝泵的進油和排油管道時，其管徑不得小于泵的進油和出油口口徑，進油管道不得過長，彎頭不得過多，否則將影響泵的工作狀態(tài)。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、當有兩臺以上的泵安裝在同一條主管線上，為便于泵的啟動，在近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、對于在較高溫度（指60℃以上）下輸送粘度大的油類（如：重油）的備用泵，必須是熱備用泵，否則泵在低溫下啟動會造成電機過載或泵損壞。（建議在靠近泵的排油管上的逆止閥旁，并聯(lián)安裝一個小回流閥，對備用泵可微啟回流閥，使泵緩慢逆轉，其逆轉速≤100轉/分，使部分熱油經常流過泵內，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、輸送介質內含有機械雜質。將嚴重影響泵的運轉和降低使用壽命，因此在泵安裝前，必須仔細清除進油管內的焊渣，沙粒等雜質，并應在進油管道靠近泵處安裝濾器，濾器網孔大小，可根據工作情況及介質粘度確定。（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，以便于觀察泵的運轉狀態(tài)。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，可用直尺測隙規(guī)在聯(lián)軸器圓周上間隔90°處檢查。8、原動機與泵的轉向必須一致，嚴格禁止原動機驅動泵逆轉。電機接線時，應先脫開電機與泵的聯(lián)軸器，對電機作試運轉。使其轉向與泵的轉向標志一致。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
