SZ water ring vacuum pump failure and maintenance

Phenomenon: reduce the degree of vacuum and exhaust enough reasons:
1. Pipeline leak 2. Packing seal wear 3. Mechanical seal, static ring wear or spring imbalance 4. Impeller and end cap clearance is too large 5. Water ring temperature is too high 6. Water supply is insufficient Treatment:
1. To eliminate leakage 2. Dianniao replacement 3. Overhaul 4. Adjust the gap 5. Increase the amount of water to reduce the water temperature 6. To increase the water supply phenomenon: excessive vibration and parts of the reasons:
1. Circulating water is too large 2. Axis bending 3. Shaft and impeller mismatch, rotor skew 4. Rotor imbalance 5. Bearing damage 6. Packing too tight 7. Bearing lubrication is poor 8. Anchor bolts loose Treatment:
1. Adjust the amount of water 2. Align or replace 3. Adjust or overhaul 4. Find balance 5. Replace the bearing 6. Adjust the gland 7. Check the lubrication 8. Fasten

Di-tertiary Butyl Peroxide

Di-tertiary Butyl Peroxide is an organic compound consisting of a peroxide group bonded to two tert-butyl groups. It is one of the most stable organic peroxides, due to the tert-butyl groups being bulky. It is a colorless liquid.

DTBP can in principle be used in engines where oxyge is limited, since the molecule supplies both the oxidizer and the fuel

DTBP is an irritant to noses, and eyes and skin. It is also flammable, so it should be handled with care.

DTBP is a liquid dialkyl peroxide. It is an efficient initiator for polymerization of olefins and

acrylic resins, and a modification agent of PP degradation, insoluble in water, soluble in

organic solvents such as toluene, acetone, styrene, etc. Freeing point lower than -30℃.
