Safety operating procedures for high-temperature and high-pressure sterilization pots
one
Comply with the operating process indicators and work pressure of the sterilization pot
0.18MP?a
Working temperature
one hundred and twenty-one
℃
.
two
Operation method of sterilization pot:
a.
First
ninety
Inject hot water at ℃ into the tank filled with goods;
b.
Add to the tank
0.15MPa
Compressed air;
c.
Open the steam valve and raise the temperature;
d.
When the specified temperature is reached, close the steam valve to maintain a constant temperature;
e.
Maintain at a constant temperature for the required time (different products require different insulation times)
;
f.
After reaching the insulation time,
Drain the hot water from the tank,
Simultaneously injecting cold water,
And maintain stable pressure inside the tank
(One)
In general
0.18-0.2MPa
)The pressure has decreased, and an air compressor is needed to replenish the air.
three
Observe the water level gauge. After filling the cold water, if the temperature reading is
thirty
℃
-50
℃
Left and right, the cooling work is completed.
Drain an appropriate amount of cold water from the tank, relieve pressure, open the lid, and retrieve the goods.
four
This equipment is strictly prohibited from exceeding the design pressure(
0.3MPa
)
Exceeding the design temperature(
one hundred and forty
℃
)Run.
five
Operators should strictly abide by safety operating procedures and job responsibility system,
And regularly maintain complete safety accessories
Sensitive and reliable, any abnormal phenomena should be promptly addressed.
six
The sterilization pot is equipped with safety valves, pressure gauges, and thermometers as safety accessories, and maintenance should be strengthened during use
With regular calibration, the opening pressure of the safety valve of this equipment is equal to the design pressure, and it should be kept sensitive and reliable regularly,
To prevent arbitrary adjustments, the accuracy of the pressure gauge should not be lower than
two point five
Grade, no lead sealed pressure gauge shall be used, its accuracy shall be up to
It should be checked at least once a year. If the pressure gauge fails to indicate, the scale is unclear, the dial is broken, and the pointer does not return to its original position after pressure relief
If the position or lead seal is damaged, it should be replaced immediately. The thermometer should be regularly calibrated and standardized before use
Calibrate the thermometer once a year in the future, if the mercury column breaks or deviates from the standard temperature by more than
zero point five
℃
,
Then send it for repair or replacement.
seven
Sterilization pots should be regularly inspected, with at least one external inspection conducted annually and at least one internal inspection conducted every three years
Testing.
eight
During use, lubricating grease should be regularly applied to sliding and rolling contact parts such as lock blocks and active ring flanges
Engine oil is used to ensure that the friction surface is in a lubricated state.
nine
、
When the sealing ring on the flange surface of the pot body is aged, damaged, or has excessive friction, it should be replaced in a timely manner to ensure sealing,
Prevent leakage.
