How to correctly use Dalian acid resistant pump products

Reasonably selecting engineering materials based on the type of chemical liquid is one of the correct methods for choosing a vertical acid resistant pump.

Choosing and using vertical pumps correctly and reasonably can fully improve the efficiency of the pump. Vertical acid and alkali resistant pumps use various materials, such as vertical acid and alkali resistant pumps, FRPP acid and alkali resistant materials, PVDF corrosion-resistant materials, wear-resistant rubber, etc. Faced with many material choices, I think many workers can play chess.

Using FRPP acid and alkali resistant materials, Dalian acid resistant pump has good acid and alkali resistance and is suitable for chemical processing plants; PVDF corrosion-resistant material has good corrosion resistance. Based on the above situation, it is necessary to select the lining of the vertical acid alkali pump reasonably according to the chemical type to improve the utilization rate of the vertical acid alkali pump.

Dalian acid resistant pumps can be widely used in electroplating, LED, metallurgy, PCB, and chemical liquids containing abrasive solid particles transported by environmental protection industries. For example, in the chemical industry, impurities can also transport corrosive liquids containing crystals when transporting slurry, electroplating wastewater, and PCBs in metallurgical beneficiation plants. About 80% of the vertical acid and alkali resistant pumps used in the industrial sector.

The correct use of vertical Dalian acid resistant pumps can effectively improve the work efficiency of the chemical industry!

Startup and operation:

1. Start the acid alkali pump and pay attention to whether the direction of the pump shaft is correct.

2. Pay attention to any abnormal sounds and vibrations during rotation.

3. Pay attention to the readings of the pressure gauge and vacuum gauge. After starting, when the readings of the pressure gauge and vacuum gauge fluctuate for a period of time and stabilize, it indicates that the pump has been filled with liquid and normal infusion operation has begun.

4. During the normal infusion operation of the pump, that is, during the self suction process, special attention should be paid to the increase in water temperature inside the pump. If this process is too long and the water temperature inside the acid and alkali resistant pump is too high, the pump should be stopped to check the cause.

5. If the temperature of the liquid inside the pump is too high and causes difficulty in self-priming, it can be temporarily stopped. The liquid in the discharge pipeline can be used to flow back into the pump or the liquid can be directly added to the pump through the liquid inlet on the pump body to reduce the temperature of the liquid inside the pump, and then it can be started.

If there is strong vibration and noise during the operation of the pump, it may be caused by cavitation. There are two reasons for cavitation: one is that the inlet pipe flow rate is too high, and the other is that the suction stroke is too high. When the flow rate is too high, the outlet control valve can be adjusted, and the reading of the temperature rise pressure gauge can be adjusted. If there is a blockage in the inlet pipeline, it should be promptly eliminated; When the suction distance is too high, the installation height of the pump can be appropriately reduced.

When the pump stops for some reason during operation and needs to be restarted, the outlet control valve should be slightly opened (not fully closed). This is beneficial for the gas to be discharged from the outlet during the self-priming process, and also ensures that the pump can be started under lighter loads.

8. Pay attention to checking whether there is any leakage in the pipeline system.
