What kind of plastic magnetic pump is good for conveying ammonia?

 

First of all, let's take a look at the ammonia solution, also known as Amonia water, which is mainly composed of NH3 ·H2O, which is an aqueous solution of ammonia, colorless, transparent and pungent. Ammonia melting point-77 ℃, boiling point 36 ℃, density 0.91g/cm ³. Ammonia is easily soluble in water and ethanol. It is easy to volatilize and has the general property of partial alkali. Ammonia water is made by passing ammonia gas into the water. Ammonia is toxic, corrosive to eyes, nose and skin, can suffocate people, and the allowable concentration of 30mg/m3 in the air. Ammonia water has a certain corrosive effect, and the corrosion of ammonia carbide water is more serious. The corrosion of copper is relatively strong, the corrosion of iron and steel is relatively poor, and the corrosion of cement is small.

 

The advantage of plastic magnetic pump for conveying ammonia is no leakage, corrosion resistance, acid and alkali resistance. The plastic magnetic pump is used to transport ammonia, and the plastic material is used to refract the molding, acid and alkali resistance and corrosion resistance. Rare earth permanent magnet is used to improve the rotation efficiency. The inner magnet dissipates heat and improves the ability of air defense.

Remember the following points in the operation of plastic magnetic pumps:

1. Check whether the direction of the electric motor is consistent with the rotation mark of the pump.

2. Check whether the oil level in the bracket oil chamber is within the prescribed range before starting the pump.

3. Open the import valve and inject enough liquid into the pump.

4. Close the outlet valve.

5. After the above steps are completed, the starting motor slowly opens the motor valve, and the position of the pressure gauge will change with the size of the outlet water. When the pressure gauge pointer points to the desired position, stop the adjustment of the valve.

6. When you need to stop, first close the outlet valve, cut off the power supply, and then close the import valve.
