微型隔膜泵吸力不足?看看这个吧

但隔膜泵毕竟是精密设备,尽管价格不高,在使用中仍然需要用心的维护,否则很容易出现以下情况。

举例说明:当某公司维修部门刚收到泵时,将泵头打开后可以看到膜片、阀片和泵腔内充满了颗粒杂质,从而使这些泵当时几乎完全没有抽力;而在做了简单清洁,或者更换一些必要部件后(这是极少数的情况),又重新恢复了活力。

For example, when a company's maintenance department has just received the pump, when the pump is opened, the diaphragm, the valve plate and the pump chamber are filled with granular impurities, so that the pump is almost completely free of force at the time; and after doing simple cleaning, or replacing some necessary components (this is a very small number of cases), it is re recovered. Vitality.

这些故障是如何发生的呢?

How did these failures happen?

不恰当的操作

Improper operation

1)安装抽滤漏斗时,漏斗的出液口靠近真空接口,导致部分滤液被吸入泵内,当滤液吹干后,析出的溶质颗粒残留在泵内。

1) when the filter funnel is installed, the outlet of the funnel is close to the vacuum interface, which causes some filtrate to be inhale in the pump. When the filtrate is blown dry, the precipitated solute particles are retained in the pump.

2)滤纸选择错误或者铺放滤纸时不小心捅破,导致部分滤纸纤维或滤液被吸入泵内。

2) improper selection of filter paper or careless puncture when placing filter paper, resulting in partial filter paper fiber or filtrate being sucked into the pump.

3)真空软管放在实验台上时,未关闭隔膜泵,台面上的灰尘和杂质被无意中吸入。

3) when the vacuum hose is placed on the test stand, the diaphragm pump is not closed, and the dust and impurities on the table surface are accidentally inhaled.

以上这些问题,可以通过增加隔膜泵保护滤器来避免。

These problems can be avoided by increasing the diaphragm pump protection filter.

保护滤器可以阻隔绝大部分颗粒,当发现保护滤器变色或者真空抽力不足时,此时更换保护滤器即可。

The protective filter can block most of the particles. When the protective filter is found to be discolouration or the vacuum is insufficient, the protective filter can be replaced at this time.
