How to use and maintain knowledge of fluoroplastic alloy chemical centrifugal pump from sdbfsteel's blog

The fluoroplastic alloy chemical centrifugal pump combines all the excellent characteristics of the magnetic pump, and the advantage is that it can be self-priming. Generally, the self-priming height can reach 2-4 meters. It fully combines all the advantages of the self-priming pump and the magnetic pump. It has the function of self-priming. , And cancel the shaft seal, the use of magnetic coupling indirect transmission, eliminating the phenomenon of dripping.

Fluoroplastic alloy chemical centrifugal pump is widely used in petrochemical industry, non-ferrous metal smelting pesticides, acid and alkali production, papermaking, pickling process, rare earth separation, electroplating, electronics, chemical foil and other industries to absorb and transport corrosive liquids below the installation position of the pump. , is a product with novel structure in the current magnetic pump variety, high efficiency, energy saving, safety and practicality.

Instructions for use and maintenance:

1. Open the outlet valve by about one third to start the self-priming pump (ie, open the valve to start), and then slowly adjust the outlet valve so that the pump cannot work normally.

2. The self-priming pump is not allowed to generate air suction during work. Once air suction occurs, the perfusion liquid must be re-drained to be self-priming. Therefore, the user must have a device to control the minimum liquid level or send someone to take care of it to prevent the medium in the pool from being emptied.

3. When conveying general non-crystalline medium, if you stop the pump for a long time and then use it, check whether the liquid in the pump body is sufficient before starting. Please make up for self-priming.

4. When conveying medium containing easy crystallization, if the pump is not used for a period of time, the pump cavity must be flushed, and no crystallization medium shall remain, so as to prevent damage when the pump is restarted after crystallization; Suck.

5. When installing the pipeline, connect the inlet pipe first, fill up the liquid and then connect the outlet pipe.

6. The self-priming height can be easily calculated by the formula: when the water is clean, the self-priming 3m/medium density = the actual self-priming height.

7. The self-priming pump cannot transport media that will produce a large number of bubbles, nor can it transport gas-liquid mixed media.
