计量泵该怎么维护？计量泵遇到故障该如何解决？这个是我们在使用计量泵的时候一件很重要的事情。我们来讲一件如何正确维护计量泵和解决计量泵的故障。

如何更换计量泵的隔膜

  1.取下固定泵头的4个螺丝。螺丝位置在计量泵的背面。

  2.在泵头松动之后，取下泵头之前，调节冲程长度到0%位置。可以保证电磁轴有足够的压力，保持其连接稳固，这样就可以旋下隔膜。

  3.向外拉液力端使螺丝从插孔内脱离。抓住液体端逆时针旋转。稍有些阻力，可以旋下隔膜。

  4.一旦隔膜被取下，检查计量泵的安全隔膜，确保其是完好的，没有任何损坏。安装新的隔膜，顺时针旋转背板和隔膜直到贴紧。调节背板，使漏液排出孔位于泵的底端。

  5.在隔膜安装完毕、并且背板漏液排出孔置于垂直位置之后，安装泵头。确保吸液阀与漏液排出孔对齐，液力端的螺丝与相应的4个孔对齐。

  6.旋转到冲程长度位置。这样可以使整套部件旋转至背板漏液排出孔与泵的底端对齐。在泵运行过程中调整液力端和隔膜至合适的位置。

  7.当液力端连同背板位置调好之后，4个螺栓以对角方式拧紧，直到合适为止。完成这项工作时应用力均匀。

二、如何拆下旧的隔膜

  通过松开4个泵头螺丝，移动液力端。旋转冲程长度到0%并抓住液力端，然后从螺丝孔滑出，那么螺丝不与它们接触，但是还把持着背板和隔膜。然后逆时针旋转此部件，稍有些阻力，隔膜会从电磁轴松动下来。如果隔膜还没有松动，在隔膜和电磁轴的接触表面用些润滑油。放置几分钟后，用一塑胶小锤轻轻敲打隔膜。然后在按照以上描述再次进行。

三、当采用自吸方式计量过氧化氢时，系统内产生气穴。如何解决这个问题？

  计量泵安装自排气泵头，采用自灌式吸液。保持吸液管线尽可能短。

四、计量泵安装、运行之后不计量药液?

  1.是否安装了排泄管并且排泄阀闭合？在计量泵引液阶段排泄阀需要打开。注意：并不是所有的计量泵都有排泄阀。

  2.在计量泵的吸入端可能有气体泄漏。液力端吸入侧连接件可能缺少O型圈或吸入阀连接松动。

  3.计量泵底阀可能阻塞，计量的药液不能通过。

  4.计量泵的冲程长度设定不合适。

  5.计量的化学药品可能在液力端结晶，致使单向阀阀球和阀座不能正常工作。

五、正在使用流量监视计量一种高粘度介质时，在引液过程中收到了流量故障指示信号，怎么做可以解决这个问题?

  对反应时间来说，脉冲持续时间可能不足够长。相对于标准的脉冲宽度80msec，流量监视器脉冲宽度扩展可以被激活，增加脉冲宽度至300msec。激活智能转换开关，取下固定电路板的护盖，移走跳线X-1。这样就激活了扩展功能，在故障指示之前允许有更多的时间。

六、如何防止冲程定位马达烧毁?

  在调节冲程位置时，确保计量泵的电机始终在运转。如果计量泵电机没有运转，冲程长度调节杆要抵抗压缩弹簧的张力，这样会导致冲程定位马达过早损坏。

How to maintain the metering pump? How to solve the problem of metering pump failure? This is an important thing when we use metering pumps. Today we talk about how to correctly maintain the metering pump and solve the problem of the metering pump.
How to replace the diaphragm of the metering pump

1. Remove the 4 screws holding the pump head. The screw is located on the back of the metering pump.

2. After the pump head is loosened, adjust the stroke length to 0% before removing the pump head. It can ensure that the electromagnetic shaft has sufficient pressure to keep it firmly connected, so that the diaphragm can be unscrewed.

3. Pull the hydraulic end outward to disengage the screw from the socket. Hold the liquid end counterclockwise. Slight resistance, you can unscrew the diaphragm.

4. Once the diaphragm is removed, check the safety diaphragm of the metering pump to ensure it is intact and without any damage. Install the new diaphragm and turn the back plate and diaphragm clockwise until tight. Adjust the back plate so that the drain hole is at the bottom of the pump.

5. Install the pump head after the diaphragm is installed and the back-plate leak drain hole is in a vertical position. Make sure that the suction valve is aligned with the leak drain hole and that the hydraulic end screw is aligned with the corresponding 4 holes.

6. Rotate to of stroke length. This will allow the entire assembly to rotate until the back plate leaks out and aligns with the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position while the pump is running.

7. When the hydraulic end is adjusted with the position of the back plate, the 4 bolts are tightened diagonally until they are suitable. Apply the force evenly when you finish this task.

Second, how to remove the old diaphragm
Dismantle the hydraulic end by loosening the 4 pump head screws. Rotate the stroke length to 0% and grasp the hydraulic end, then slide out of the screw hole, then the screws do not touch them but they also hold the back plate and diaphragm. Then rotate this part counterclockwise, with some resistance, and the diaphragm will loosen from the electromagnetic shaft. If the diaphragm has not loosened, apply some lubricant to the contact surfaces of the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a plastic hammer. Then proceed again as described above.

Third, when self-priming is used to measure hydrogen peroxide, cavitation occurs in the system. how to solve this problem?

The metering pump is installed from the exhaust pump head and is self-priming. Keep the suction line as short as possible.

Fourth, metering pump installation, operation, do not measure the liquid?

1. Is a drain tube installed and the drain valve closed? The drain valve needs to open during the priming phase of the metering pump. Note: Not all metering pumps have drain valves.

2. There may be a gas leak at the suction side of the metering pump. Fluid end suction side connections may lack o-rings or loose suction valve connections.

3. The bottom valve of the metering pump may be clogged and the metered liquid may not pass.

4. The stroke length of the metering pump is not set properly.

5. The metered chemicals may crystallize at the hydraulic end, causing the check valve ball and seat to not work properly.

5. When a high-viscosity medium is being measured using flow monitoring, a flow failure indication signal is received during the priming process. How can this problem be solved?

The pulse duration may not be long enough for reaction time. With respect to the standard pulse width of 80 msec, the flow monitor pulse width extension can be activated to increase the pulse width to 300 msec. Activate the intelligent transfer switch, remove the cover of the fixed circuit board, and remove the jumper X-1. This activates the extended function, allowing more time before the fault indication.

Six, how to prevent the stroke positioning motor burned?

When adjusting the stroke position, make sure the metering pump motor is always running. If the metering pump motor is not running, the stroke length adjustment lever will resist the tension of the compression spring, which will result in premature failure of the stroke positioning motor.
