●3G三螺杆泵工作原理:

　　3G型三螺杆泵是转子型容积泵，适于输送各种不含固体颗粒，无腐蚀性油类及类似油的润滑性液体、输送液体粘度2~760mm2/s，温度不超过80℃,超过80℃可用高温泵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型三螺杆具有多种结构，一般小流量泵衬套和泵体合为一个，可以卧式和立式安装。进油口方向可相隔90°任意安装，轴封多数为机构密封。中等流量以上泵，衬套为一个单独的零件固定于泵体内，螺杆轴端装有平衡环以液力平衡其轴向力。一般结构为卧式。进油口方向亦可以相隔90°任意安装。改变泵体后可制成立式。轴封根据情况有机械密封和软填料密封两种结构。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型三螺杆泵轴伸支承较小，应由原动机经弹性联轴器直接驱动，不得用皮带轮等会产生额外径向力较大的传动方式传动。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三螺杆泵输送各种油类时应注意事项：When conveying various oil matters should be paid attention to:

   1、输送40~150mm2/s的油类 合适，允许按泵的 高工作压力使用。2、输送40mm2/s以下的油类，为保证泵的流量及寿命应降压使用。3、输送150mm2/s以上的油类，且进油管道过长，弯头过多，泵工作时如产生噪音或振动现象，则应考虑更换低一级转速的电机运转或缩短吸入管道，减少弯头。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型三螺杆泵安装要求:3 g type three-screw pump installation requirements:

   1、安装前应检查泵的油封是否良好，并检查泵在运输中是否损坏，可用手转动联轴器是否有卡劲现象，如有则应拆泵进行清洗，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、安装泵的进油和排油管道时，其管径不得小于泵的进油和出油口口径，进油管道不得过长，弯头不得过多，否则将影响泵的工作状态。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、当有两台以上的泵安装在同一条主管线上，为便于泵的启动，在近泵的排油管上必须安装逆止阀。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、对于在较高温度（指60℃以上）下输送粘度大的油类（如：重油）的备用泵，必须是热备用泵，否则泵在低温下启动会造成电机过载或泵损坏。（建议在靠近泵的排油管上的逆止阀旁，并联安装一个小回流阀，对备用泵可微启回流阀，使泵缓慢逆转，其逆转速≤100转/分，使部分热油经常流过泵内，达到泵热备用目的）。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、输送介质内含有机械杂质。将严重影响泵的运转和降低使用寿命，因此在泵安装前，必须仔细清除进油管内的焊渣，沙粒等杂质，并应在进油管道靠近泵处安装滤器，滤器网孔大小，可根据工作情况及介质粘度确定。（一般可用40~80目网），过滤面积一般不得小于进油管横截面积的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、尽量在泵进油和排油口处的螺纹孔上连接压力表和真空表，以便于观察泵的运转状态。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、原动机与泵的转轴必须在同一中心线上，可用直尺测隙规在联轴器圆周上间隔90°处检查。8、原动机与泵的转向必须一致，严格禁止原动机驱动泵逆转。电机接线时，应先脱开电机与泵的联轴器，对电机作试运转。使其转向与泵的转向标志一致。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
