1 、

螺杆泵(单螺杆泵,三螺杆泵,双螺杆泵)

安装及装配偏差引起的振动。泵体及推力瓦在安装后的水平度和扬水管的垂直度超差将引起泵体的振动，同时这三个控制值又有一定关联。泵体安装完后，扬水管及泵头（不包括滤网）总长为 26m ，均为悬空挂置，如果扬水管垂直度偏差过大，在泵转动中必将造成扬水管及轴等剧烈振动。扬水管垂直度超差过大还将在泵运转过程中产生交变应力，引起扬水管的断裂。深井泵装配完后，扬水管在总长度范围内，垂直度误差应控制在士 2mm 。泵的纵横向水平误差 <0.05/l000mm 。对泵头叶轮静平衡允差不大于 10g ，组装完后应有 8-12mm 上下串动间隙。安装及装配间隙误差是造成泵体振动的重要原因。 1, stainless steel pump installation and assembling deviation caused by vibration. Pump body and thrust tile in after installation levelness and uplift pipe vertical degree out-of-tolerance will cause the vibration of the pump body, at the same time, the three controlling value also has the certain relevance. Pump body after installation, to lift up the water pipe and pump head (not including screen) whose total length is 26 m, are impending hang buy to, if Yang pipe verticality deviation is too big, in the pump rotation will cause Yang pipe and pipe shaft and violent vibration. Yang pipe verticality out-of-tolerance big will also in the pump running process of alternating stress, cause Yang pipe rupture. Deep well pump assembly after, to lift up the water pipe in total length range, the perpendicularity errors should be controlled in the 2 mm. The vertical and horizontal pump to level error < 0.05 / l000mm. The pump head impeller static balance tolerance is not more than 10 g, assembly should be after 8-12 mm fluctuation string dynamic clearance. Installation and assembly clearance error caused by the vibration of the pump body is an important reason.
    2 、 螺杆泵(单螺杆泵,三螺杆泵,双螺杆泵)传动轴的涡动。涡动又称甩转，是旋转轴发生的一种自激振动，它既不具有自由振动的特征，也不属受迫振动的类型。它的特征是轴在轴承间表现为回转运动，这种振动并不是在转轴到达临界转速时发生，而是在较大范围内发生且与转轴本身的转速关系较少。深井泵的甩转主要由轴承润滑不充分引起，如果轴与轴承间的问隙较大，则回转运动方向与轴的转动方向相反，这种情况又称轴的抖动。特别是深井泵传动轴很长，橡胶轴承和轴的配合间隙为 0.20 － 0.30mm ，当轴与轴承存在一定间隙，轴与轴承不同心，中心距较大，间隙中又缺乏润滑时，例如深井泵橡胶轴承的润滑供水管断裂、堵塞、误操作造成供水不充分或不及时等情况下，更易出现抖动。在某一瞬时转动着的轴颈与橡胶轴承在一点接触，轴颈受到轴承给它的切向力，设力作用方向与轴的转速的方向相反，将此力向轴心平移，其力学效应相当于一个反时针方向的转矩和一个作用在轴颈中心的力，这个力平行于轴承壁接触点的切线方向，并且有使轴颈下移的趋势，因此轴颈将沿轴承壁作纯滚动，相当于一副内齿轮，这样就形成与轴旋转方向相反的回转运动。 2, the drive shaft, the vortex. Vortex also called left turn, is the axis of rotation happened a self-excited vibration, it is neither has the free vibration characteristics, also do not belong to the type of forced vibration. It is characterized by the axis in the bearing performance between for rotary motion, this kind of vibration and not in the shaft to critical speed change, but in a greater scope and shaft itself occurred and the speed of the less relationship. The deep well pump left turn mainly consists of bearing lubrication don't fully cause, if the shaft and bearing between the larger ask gap, the rotary motion direction and axial rotation direction on the contrary, this kind of situation is also called shaft jitter. Especially deep well pump shaft is very long, rubber bearing and shaft fit clearance 0.20 0.30 mm, when the shaft and bearing has certain gap, shaft and bearing different heart, center distance is larger, the clearance and the lack of lubrication, such as deep well pump rubber bearing lubrication water supply pipe fracture, jams, misoperation cause water supply inadequate or not timely, etc, are more likely to have jitter. In one instantaneous rotation of the shaft and rubber bearing in a point contact, journal by bearing to its tangential force, a force with the direction of the shaft speed direction on the contrary, the force to axial translation, the mechanical effect is equivalent to a counterclockwise torque and a role in the journal center of force, the force bearing wall contact point parallel to the direction of tangent and make journal down trend, so the journal will be along the bearing wall be pure rolling, equivalent to a pair of internal gear, thus forming and axis rotation direction opposite rotary motion.
