All devices in use are more or less there will be some condition, has nothing to do some security issues, not sterilization equipment, and security issues are related, said below is the problem for sterilization kettle using common faults let everybody know, when the autoclave leaking steam of emergency, please do not immediately pressure (such as in the case of high temperature above 80 ℃, pressure drops, deformation or detonation spray products would happen), follow these steps:

1, the temperature rising

Such as leakage, immediately stop, manual will withdraw the high-temperature cylinder hot water, open the cold water to cool (and slow pressure - synchronization with cooling), to take out the products to other sterilization kettle sterilization, avoid wasting hot water; Such as steam leakage, such as temperature above 80 ℃ has not been achieved, can stop the (synchronous temperature and pressure) after continue to move to other sterilization kettle sterilization, such as leakage, and the temperature is near constant temperature, can be manually open steam, will have a thermostatic temperature to 121 ℃ and after completion of sterilization, temperature and pressure, take out the products. Notify the maintenance process

2, constant temperature stage

Such as leakage, insufficient level (level 170 cm, actually only 140 cm), so suggest to continue process is completed, isolation products and inform QC checking and provide processing solution by QC department (scrap or sterilization or packaged goods directly again); Find the abnormal points and inform the maintenance treatment, empty kettle running OK rear can put into production use. Such as steam leakage, sterilization kettle unable to maintain a constant temperature, method 1: manual steam valve, make the temperature continue to back to the process temperature sterilization, thermostatic switch back to the automatic temperature and pressure, after the separation products, inform the QC sampling and wait for the QC process; Method 2: stop, after manual temperature and pressure relief, product withdrawal will be moved to the continue to other sterilization kettle sterilization (can leapfrog directly - constant temperature stage), after the isolation products, inform the QC sampling and wait for the QC process. Inform maintenance processing steam leakage fault, repair, rear can use.

3, the cooling stage

If a leak in the process of pressure situation, should continue to execute and normal products. Without isolation. The handle exceptions, notify maintenance after empty kettle running OK rear can use.

The relief valve failure suddenly. When faced with the overpressure, relief valve is not open, manually pull (safety valve handle, recovery and relief.

Methods: in the process of sterilization, whether in sterilization phase, pressure is too high, can be manually operation, at this time manually open the relief valve handle pressure. Note: this operation must be slow, fell to process the required pressure. As in the constant temperature stage, can continue to manually perform sterilization operations; As in the cooling stage, the pressure cooling (simultaneous); As in the heating stage, the pressure cooling (simultaneous), cooling products, moved to other sterilization kettle sterilization; Notify the maintenance processing safety valve, empty kettle operation rear can normal use after repair.

Cooling equipment in special circumstances need to manually, the pot must ensure that has certain positive pressure, prevent into cold water in an instant, the pot on the rapid condensing steam pressure, causing dented cans. The employee's actual operation at present: the above situation can only appear in the product after the constant temperature, such as sterilization kettle temperature 121 ℃, the pressure in the kettle is 0.20 Mpa, the need to manually cooled to 41 ℃ and atmospheric pressure. First of all, the hot water inside the autoclave withdraw high hot water tanks, tank pressure is constant, the opening the cold water valve, temperature at the same time, the manual pressure relief valve, an open a close operation mode, makes the product inside the kettle to reduce temperature and pressure in synchronization. To reduce temperature to 80 ℃, the pressure in the kettle is below 0.10 Mpa, can rapid cooling step-down operation at this time.
