Sanyo Sterilizer Beijing Maintenance Co., Ltd.

.When Sanyo stacks sterilization items, it is strictly forbidden to block the air outlet of the steam release valve. Space must be left to ensure that the equipment can deflate smoothly. Otherwise, the safety valve will not work due to the blockage of the air outlet, causing an accident. .Before each use of the Sanyo autoclave, you must check whether the water volume in the sterilization barrel is maintained at the foot rest.
3. When sterilizing liquids, the liquid should be canned in a hard heat-resistant glass bottle, preferably no more than 3/volume. Use a cotton gauze stopper at the mouth of the bottle. Do not use unperforated rubber. Or cork.
Sanyo sterilizer after-sales hotline:
Sanyo's special note: steam is not allowed to be released immediately when the sterilization liquid is finished. The residual gas must be released after the pressure gauge pointer returns to zero.
.Do not put items of different types with different sterilization requirements, such as dressings and liquids, together for sterilization, to avoid focusing on one at the expense of the other and causing losses.
. When the sterilization of the high-pressure sterilizer is completed, the pressure gauge pointer must return to zero, and the steam release valve strap must be placed in the steam release position. Allow outside air to enter the autoclave. After the vacuum is eliminated, the container lid can be opened.
. After the pressure gauge of the autoclave has been used for a long time, the pressure indication is incorrect or cannot return to zero. It should be repaired in time. It should be compared with the standard pressure gauge regularly. If it is abnormal, it should be replaced with a new gauge.
.The autoclave should be kept clean and dry at ordinary times to extend its service life. The rubber sealing gasket will age over time and should be replaced regularly.
Add water: first close the drain valve and adjust the main valve to full drain. Then, open the water inlet valve and put distilled water into the steam generator. When the water reaches about ~ from the top of the water meter, close the water inlet valve and turn the main valve to closed.
. Loading the pot: Put the items to be sterilized into the pot. Be careful not to stuff them too tightly or full. The Erlenmeyer flask and test tube containing the culture medium should be placed upright or moderately tilted. To prevent culture medium from contaminating the cotton plug during the sterilization process.
Close the door: Turn the locking handle clockwise to the red arrow to allow the support to enter the door ring. Then rotate the octagonal turntable to make the door and gasket tightly closed to ensure that there is no air leakage during sterilization. It should not be too tight to avoid damaging the gasket.
. Power on and heat: Turn the knob of the power control switch to the open position and the power indicator light will light up, indicating that the power is on. Then press the sterilization steam pressure required to sterilize the items and turn the rotary cutter to...,... or... at. At this time, the electric heating indicator light is on, indicating that electric heating is on.
. Heat preservation and pressure preservation: When the steam in the steam jacket reaches the automatic control pressure with heating, the electric heating indicator light will automatically go out, indicating that heating has stopped. As the heat dissipates and the pressure decreases, the electric heating indicator light lights up again, indicating continued heating, which indicates that the pressure controller is working properly. When the steam in the jacket is heated to the selected control pressure, the steam in the jacket can be introduced into the sterilization chamber for sterilization. At this time, the condensation valve in front of the vapor-liquid separator should be opened slightly, and then the main valve should be adjusted to disinfection. The steam in the jacket layer will enter the sterilization chamber through the main valve for disinfection, and the condensed water will be automatically discharged through the vapor-liquid separator. At this time, the steam pressure in the steam jacket drops rapidly, while the steam pressure in the sterilization chamber gradually rises. The thermometer in the sterilization chamber also rises as the items are heated by the steam. When the temperature of the watch rises to the required sterilization temperature (usually ℃), start calculating the sterilization time and maintain the temperature until the sterilization is completed.
. Out of the pot: After sterilization is completed, immediately cut off the power supply. According to the nature and requirements of the sterilized items, decide whether the steam in the sterilization room should be naturally cooled or should be discharged slowly or quickly, for example, instruments, utensils, solid koji materials , soil, peat and other items that will not be affected by a sudden drop in pressure, the main valve can be directly adjusted to slow discharge and fast discharge to quickly discharge the steam in the disinfection room. When the pressure in the sterilization chamber drops to 100, you can slowly turn the pot door turntable and turn the locking handle to open the door. Take out the sterilized items after ~3, and the sterilized items will be relatively dry at this time. When the sterilization of solutions, culture media and other items is completed, the main valve can only be adjusted to slow discharge to allow the steam in the sterilization chamber to be slowly discharged to avoid a sudden reduction in pressure causing violent boiling of the culture medium. You can also close the main valve after sterilization is completed and allow the sterilized items to cool naturally. When the pressure gauge of the Sterilizer drops to a low value, turn the main valve to slow discharge for a few minutes and take out the sterilized items.
Continuous operation: If there are many sterilized items that require continuous operation, the water level should be checked first. It can be used continuously when there is enough water. If you need to add water, adjust the main valve to full discharge, open the water inlet valve and add water before continuing the operation.
Maintenance: After each sterilization is completed, turn off the power, stop heating, and then adjust the main valve to full exhaust to discharge the steam in the jacket. Open the platinum door a little to distribute the remaining steam to keep the wall of the sterilization chamber dry at all times, and at the same time remove the remaining water in the steam generator.

Principles of high-pressure sterilizers and precautions for use
Vertical pressure steam sterilizers are widely used in hotels, hospitals and other departments to sterilize heat-resistant items. It has adjustable pressure and temperature functions and protection functions such as low water level power off and anti-dry burning. It is easy to use and has high reliability. The following briefly analyzes the working principle and introduces the precautions for use.
1. Working principle of Sanyo sterilizer
The sterilizer circuit consists of three parts: main circuit, control circuit and indication circuit. The main circuit is powered by three-phase 3 AC, which is added to the main contact (normally open) -, -, power side of the AC contactor through the fuse, , 3. Its load side is connected to the electric heater,,3. After the AC contactor is normally closed, its main contacts -, -, are closed. Formed connection form. The electric heater receives electricity and generates heat to heat the water in the water tank. At the same time, 3 AC currents are drawn from the load side of the fuse, and passed through the fuse and band switch as the power supply for the control circuit and indicator light circuit. When the band switch is closed. -, -Connect 3 AC current and divide it into two channels: one channel is added to the primary of the transformer, and the secondary output. 3 AC power is used as the power supply for each relevant indicator light. At this time, the power indicator light is on. The other channel is the control loop power supply. 3 alternating currents pass through the relay - normally closed contact, low water level reset button B, band switch - and pressure selection travel switch to both ends of the AC contactor coil. When powered, the main contacts -, -, are closed. , the electric heater, ,3 gets electricity and starts to heat. Heating the water in the tank. As the water temperature in the box continues to rise, the steam generated enters the sterilizer. When the steam pressure in the sterilizer reaches the set value, the pressure bellows deforms, pushes the pressure selection travel switch (or) to open, cuts off the AC contactor coil power, and releases the power. The normally open contact is disconnected and the electric heater stops heating. The pressure selection travel switch is driven by three bellows that can measure different pressures. Through the band switch-turn on the AC contactor current. Achieve the selection of sterilization pressure and temperature required for different items.
After the transformer steps down 3 AC, the secondary output is about AC, which is rectified by the rectifier bridge R and provides DC power to the low water level protection circuit.
When the water level in the water tank is lower than the lower limit specified value. The switch contact in the low-water conductive column is closed, the triode is cut off, the potential of the b pole is approximately the ground potential, and it is turned on. The relay pulls in, the normally open contact - closes, connects the relay coil, the relay pulls in, the normally closed contact - disconnects the AC contactor coil power, the normally open contact -, -, disconnects, cuts off the power supply of the electric heater,, 3. Avoid malfunctions such as dry burning and fire caused by heating under low water level conditions. At the same time, the normally open contact is closed, the low water level light is on, and a prompt is issued. -The normally open contact closes and supplies power to the relay to achieve self-holding. When the water level returns to normal, it must be inspected by staff. When confirming that it is not a false water level, press the low water level reset button B. The relay will be released when the power is off, the self-holding contact will be disconnected, and the normally closed contact will be closed before the sterilizer can start working again.
2. Precautions for using vertical pressure steam sterilizer
． Before use, check whether the power supply is normal and fill the water tank with water to the rated water level. Usually the water level should be above the middle of the high and low water levels to avoid replenishing water midway. After placing disinfectant items in the pot, close the door and lock it tightly.
． Turn the band switch, -, - to turn on the power supply of the control indication circuit, and the power indicator light will light up.
3. According to the pressure and temperature requirements of the disinfection items, continue to rotate the band switch to select the appropriate pressure level. At this time, the corresponding pressure selection indicator light (or, 3) will light up. The corresponding pressure selector switch turns on the AC contactor coil 3 power supply through - and closes. The electric heater starts to heat the water in the water tank.
． Start timing when the pressure and temperature in the sterilizer reach the set value. When the disinfection time is reached, cut off the power supply, open the drain valve, and discharge the remaining water vapor in the sterilizer. After the pressure gauge indicates zero. Only then can the door of the sterilizer be opened and the sterilized items taken out.
． When the low water level alarm light is on. The water level should be checked and the water tank should be replenished when it is confirmed to be below the lower limit. End of hydration. Press the low water level reset button B to resume work, but the disinfection time needs to be recalculated. It is therefore important to check the water level before starting disinfection. Make sure that the water level is above the middle of the high and low water levels before disinfection and that there is no leakage in the pipes.
． The pressure gauge and safety valve used in the sterilizer should be checked by the quality inspection department every six months, and any problems found should be eliminated in a timely manner. When the sealing ring ages and causes air leakage, it should be replaced in time to ensure the disinfection effect.
