The corrosion resistant submerged pump realizes suction, compression and exhaust by the change of the pump cavity volume, so it is a centrifugal pump that can change the volume. The pump body is made of stainless steel. Two or more impellers are installed on the pump shaft, and they are connected in series to do work at the same time. When the liquid passes through each impeller, the pressure increases in turn under the action of centrifugal force, and then a higher lift is obtained. It is suitable for non-corrosive liquids and is mainly composed of four parts: stator, rotor, bearing and shaft seal. If vibration occurs during operation, the main reasons are loose bolts, rotor imbalance, etc. The solution is to tighten bolts and straighten bearings. Wait.

During the use of the corrosion resistant submerged pump, improper use will cause it to be corroded. Let's analyze the specific factors that cause the equipment to corrode.

1. The surface of stainless steel adheres to organic juices (such as vegetables, noodle soup, sputum, etc.), and in the presence of water and oxygen, organic acids are formed, and organic acids will corrode the metal surface for a long time.

2. On the surface of stainless steel, there are deposits of dust or heterogeneous metal particles containing other metal elements. In humid air, the condensed water between the deposits and the stainless steel connects the two into a micro-battery, which triggers an electrochemical reaction. , the protective film is damaged, called electrochemical corrosion.

3. In the polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), when encountering condensed water, it will form the liquid point of sulfuric acid, nitric acid and acetic acid, causing chemical corrosion.

4. The surface of stainless steel adheres to substances containing acids, alkalis, and salts (such as alkali water and lime water splashing from decoration walls), causing local corrosion.

The above are several factors that will lead to corrosion resistant submerged pump. Users need to avoid these situations to ensure the normal operation of the equipment.
