一、螺杆泵的转速选用

螺杆泵的流量与转速成线性关系，相对于低转速的螺杆泵，高转速的螺杆泵虽能增加了流量和扬程，但功率明显增大，高转速加速了转子与定子间的磨耗，必定使螺杆泵过早失效，而且高转速螺杆泵的定转子长度很短，极易磨损，因而缩短了螺杆泵的使用寿命。

通过减速机构或无级调速机构来降低转速，使其转速保持在每分三百转以下较为合理的范围内，与高速运转的螺杆泵相比，使用寿命能延长几倍。

二、螺杆泵的品质

螺杆泵的种类较多，相对而言，进口的螺杆泵设计合理，材质精良，但价格较高，服务方面有的不到位，配件价格高，订货周期长，可能影响生产的正常运行。

国内生产的大都仿制进口产品，产品质量良莠不齐，在选用国内生产的产品时，在考虑其性价比的时候，选用低转速，长导程，传动量部件材质优良，额定寿命长的产品。

三、确保杂物不进入泵体

湿污泥中混入的固体杂物会对螺杆泵的橡胶材质定子造成损坏，所以确保杂物不进入泵的腔体是很重要的，很多污水厂在泵前加装了粉碎机，也有的安装格栅装置或滤网，阻挡杂物进入螺杆泵，对于格栅应及时清捞以免造成堵塞。

四、避免断料

螺杆泵决不允许在断料的情形下运转，一经发生，橡胶定子由于干摩擦，瞬间产生高温而烧坏，所以，粉碎机完好，格栅畅通是螺杆泵正常运转的必要条件之一，为此，有些螺杆泵还在泵身上安装了断料停机装置，当发生断料时，由于螺杆泵其有自吸功能的特性，腔体内会产生真空，真空装置会使螺杆泵停止运转。

五、保持恒定的出口压力

Five, maintain a constant outlet pressure

螺杆泵是一种容积式回转泵，当出口端受阻以后，压力会逐渐升高，以至于超过预定的压力值。此时电机负荷急剧增加。传动机械相关零件的负载也会超出设计值，严重时会发生电机烧毁、传动零件断裂。为了避免螺杆泵损坏，一般会在螺杆泵出口处会安装回油阀，用以稳定出口压力，保持泵的正常运转。

Screw pump is a kind of rotary pump, when the outlet end is blocked, the pressure will gradually increase, so that more than a predetermined pressure value. At this time, the motor load increased dramatically. Transmission machinery related parts of the load will exceed the design value, serious will occur when the motor burned, transmission parts broken. In order to avoid damage to the screw pump, the general will be in the screw pump outlet will be installed back to the oil valve, with a stable outlet pressure, to maintain the normal operation of the pump.

常见问题处理

Common problems

1.泵体剧烈振动或产生噪音：

1 severe vibration or noise of the pump body:

产生原因：水泵安装不牢或水泵安装过高；电机滚珠轴承损坏；水泵主轴弯曲或与电机主轴不同心、不平行等。

Cause: pump installation is not strong or the installation of pump is too high; motor ball bearing damage; water pump shaft bending or with the motor spindle is not concentric, not parallel, etc..

处理方法：装稳水泵或降低水泵的安装高度；更换电机滚珠轴承；矫正弯曲的水泵主轴或调整好水泵与电机的相对位置。

Treatment method: the installation height of the pump or the lower water pump, the replacement of the motor ball bearing; the correct bending of the pump shaft or the relative position of the pump and the motor.

2.传动轴或电机轴承过热：

2 drive shaft or motor bearings overheating:

产生原因：缺少润滑油或轴承破裂等。

Cause: lack of lubricating oil or bearing rupture, etc..

处理方法：加注润滑油或更换轴承。

Handling method: filling the lubricating oil or replacing the bearing.

3.水泵不出水：

3 no water pump:

产生原因：泵体和吸水管没灌满引水；动水位低于水泵滤水管；吸水管破裂等。

Cause: pump body and suction pipe is not filled with water; the dynamic water level is lower than the water pump, water pipe rupture, etc..

螺杆与壳体之间的密封面是一个空间曲面。在这个曲面上存在着诸如ab或de之类的非密封区，并且与螺杆的凹槽部分形成许多三角形的缺口abc、def。这些三角形 的缺口构成液体的通道，使主动螺杆凹槽A与从动螺杆上的 凹槽B、C相连通。而凹槽B、C又沿着自己的螺线绕向背面， 并分别和背面的凹槽D、E相连通。由于在槽D、E与槽F(它属 于另一头螺线）相衔接的密封面上，也存在着类似于正面的三 角形缺口a’b’c’，所以D、F、E也将相通。这样，凹槽ABCDEA也就组成一个“∞” 形的密封空间（如采用单头螺纹，则凹槽将顺轴向盘饶螺杆，将吸排口贯通，无法形成密封）。不难想象，在这样的螺杆 上，将形成许多个独立的“∞”形密封空间，每一个密封空间所占有的轴向长度恰好等于累杆的导程t。因此，为了使螺杆 能吸、排油口分隔开来，螺杆的螺纹段的长度至少要大于一个导程。

The sealing surface between the screw and the shell is a space surface. There are non sealing areas such as AB or de on this surface, and a plurality of triangular gap ABC and def are formed in the groove of the screw. The gap of these triangles constitutes a liquid channel, which makes the active screw groove B is connected with the groove A and C on the driven screw. The groove B, C and along the spiral wound to his back, and D, respectively and the groove on the back of the E connected. Because in the slot D, e and slot f (it belongs to the other end of the spiral) convergence of the sealing surface, there are also similar to the front of the angle shaped notch a 'B' C ', so D, F, e will be connected. In this way, groove ABCDEA also constituted a "robust" shaped seal space (such as the use of single thread, the groove will be along the axial direction disc Rao screw, the suction outlet through, unable to form a tight seal. Is not difficult to imagine, in such a screw, will form many independent "infinity" shaped sealed space, each a sealed space occupied by the axial length of is exactly equal to the tired rod guide t. Therefore, in order to make the screw can suck the oil port, the length of the screw is at least more than one lead.

安全使用方法

Safe use method

一、螺杆泵的停车

A screw pump parking

螺杆泵停车时，应先关闭排出停止阀，并待泵完全停转后关闭吸入停止阀。

When the screw pump stops, should first close the discharge stop valve, and to be completely stopped after the pump to stop the suction stop valve.

螺杆泵因工作螺杆长度较大，刚性较差，容易引起弯曲，造成工作失常。对轴系的连接必须很好对中；对中工作是在安装定位后进行，以免管路牵连造成变形；连接 管路 时应独立固定，尽可能减少对泵的牵连等。此外，备用螺杆，在保存时采用悬吊固定的方法，避免因放置不平而造成的变形。

Screw pump due to the larger length of the screw, the rigidity is poor, easily lead to bending, resulting in abnormal work. The connection of the shaft must be good to; to work best in the installation and positioning, so as not to cause deformation of pipeline involved; connecting pipe should be fixed independently, as far as possible to reduce the pump implicated. In addition, the spare screw, in the preservation of the best use of the suspension fixation method, to avoid the deformation caused by uneven placement.

二、螺杆泵的起动

Two, the start of the screw pump

螺杆泵应在吸排停止阀全开的情况下起动，以防过载或吸空。

Screw pump should be in the suction line to stop the valve open to start, to prevent overload or suction.

螺杆泵虽然具有干吸能力，但是必须防止干转，以免擦伤工作表面。

Although the screw pump has the ability to do, but must prevent the dry rotation, so as not to scratch the surface of the work.

假如泵需要在油温很低或粘度很高的情况下起动，螺杆泵应在吸排阀和旁通阀全开的情况下起动，让泵起动时的负荷，直到原动机达到额定转速时，再将旁通阀逐渐关闭。

If oil temperature is low or high viscosity pump required starting, the screw pump should be in the suction valve and bypass valve is fully opened, the starting and allow the pump to start when the minimum load until the original motivation to reach the rated speed, and then gradually closed the bypass valve.

当旁通阀开启时，液体是在有节流的情况下在泵中不断循环流动的，而循环的油量越多，循环的时间越长，液体的发热也就越严重，甚至使 泵 因高温变形而损坏，必须引起注意。

When the bypass valve is open, the liquid is under the throttle in the pump in continuous circulation flow, circulation and more fuel, cycle time is long, the more serious heat the liquid, and even the pump for high temperature deformation and damage, must pay attention.

三、螺杆泵的运转

Three, screw pump operation

螺杆泵必须按既定的方向运转，以产生一定的吸排。

Screw pump must be operated in accordance with the established direction to produce a certain suction line.

泵工作时，应注意检查压力、温度和机械轴封的工作。对轴封应该允许有微量的泄漏，如泄漏量不超过 20-30 秒/ 滴，则认为正常。假如螺杆泵在工作时产生噪音，这往往是因油温太低，油液粘度太高，油液中进入空气，联轴节失中或泵过度磨损等原因引起。

When the pump is working, should pay attention to check the pressure, temperature and mechanical seal work. On the seal should be allowed to have trace amounts of leakage, such as leakage of not more than 20-30 seconds / drop, is considered normal. If the screw pump noise at work, this is often because the temperature is too low, the oil viscosity is too high, the oil into the air, or pump coupling loss excessive wear causes.

选用及应用

Selection and Application

螺杆泵因其有可变量输送、自吸能力强、可逆转、能输送含固体颗粒的液体等特点，在污水处理厂中，广泛地被使用在输送水、湿污泥和絮凝剂药液方面。螺杆泵选用应遵循经济、合理、可靠的原则。如果在设计选型方面考虑不周，会给以后的使用、管理、维修带来麻烦，所以选用一台按生产实际需要，合理可靠的螺杆泵既能保证生产顺利进行，又可降低修理成本。

Screw because there can be variable transmission, self-priming capability, and can be reversed to transport with characteristics of solid particles in the liquid,, in sewage treatment plant, are widely used in the transportation of water, wet sludge and liquid flocculant aspect. Screw pump selection should follow the principle of economic, reasonable and reliable. If in the selection of design consideration not week, for later use, management, maintenance, trouble, so choose one according to the actual needs of production, reasonable and reliable screw pump can guarantee the smooth progress of production, but also reduce the repair costs.

如何保养

1.1在螺 杆泵停泵时检查齿轮箱内的油位。若有必要，拆下注油螺塞，加油至油标的中心处为止。

Check oil level gear box 1.1 in screw pump when the pump stops. If necessary, remove the oil plug, gas to oil standard center.

1.2听听是否有异常噪声与震动。

1.2 to hear whether there is abnormal noise and vibration.

1.3在泵运转时检查泵是否有泄漏。

注意：对于机械 密封，在大多数情况下，由于汽化导致从密封泄液孔处观察不到泄漏，但有时少量而又稳定的泄漏是允许的。

Note: for mechanical seals, in most cases, the leakage is due to the vaporization of the liquid from the sealing leakage hole, but sometimes a small amount of leakage is allowed.
