Warning The setting of drainage pipe shall prevent the generation of drainage back pressure, otherwise the sterilization or drying effect will be affected due to the poor discharge of condensate water. Drainage pipe materials shall be high temperature resistant (140°C) and anti-aging materials.
2)Various equipment power equipment requirements
• Steam source: it is best to set up a steam water separator on the steam source pipe. The separator can remove the solid particles and condensate carried in the steam delivery process to enable the sterilizer to obtain a high-quality steam source. The steam source pressure is 0.30- -0.50MPa. If the steam source pressure is too high (> 0.5MPa), the pressure relief valve should be added to the transmission pipeline to ensure that the steam source pressure fluctuation does not exceed 10%. Industrial steam source pipe for 1 inch internal thread connection. If the sterilization equipment is far away from the boiler, the diameter of the steam transmission pipe should be increased to reduce the pipe resistance. When double steam, pure steam line is 1 inch joint. Steam conveying pipeline shall be insulated to reduce the loss of steam. In order to observe the steam supply situation timely, the steam source valve and a pressure gauge of 0-1MPa shall be installed on the steam source pipeline into the interlayer or inner chamber.
• Water source: the inlet pipe is a 1 / 2 inch thread pipe. Connect a 0-0.6MPa range pressure gauge and valve to the inlet sterilwater pipe to observe and control the water pressure.
Warning Softened water shall be used to ensure long-term operation of the water ring pump and condenser.
• Compressed gas source: (gas source pressure: 0.5-0.7MPa) compressed gas pipe is 8 (or 6) hose. Compressed air shall be directed by the main road near the sterilizer and fitted with a stop valve, a pressure relief valve, a pressure gauge, and an 8 (or 6) plug-in direct terminal quick change connector.
• If there is no compressed gas source, you can buy a 60 L / minute medical oil-free compressor for a single set of equipment to support the use.
• power supply: the power supply shall be three-phase five-wire system (three-phase fire wire, one zero wire, one ground wire), the user is required to have two power wires, one is for the power power cord of liquid ring vacuum pump, the other is for the control wire. Install the power switch box near the equipment on the rear wall of the sterilizer with a three-phase switch switch (or circuit breaker) and a single-phase switch switch (or circuit breaker).

The screen is as shown in Figure 3:
This screen will display for 5 seconds, the buzzer will ring for 5 seconds, and the screen will automatically turn off after 5 seconds.
Figure 3
When the vacuum pump starts while closing the front door, while the solenoid valve moves, pull the sealant strip in the sealing groove of the front end box, and the door motor moves. After the door plate reaches the closed position, the door stroke switch is closed, the front door indicator light is on, and close the front door operation is completed. When the door needs to be sealed, the compressed air passes through the solenoid valve into the front-end frame sealing groove, and the sealant strip is pushed out and close to the door plate, to realize the sealing of the door.
2)The front door open
After sterilization, the internal chamber pressure is ± 10KPa. Opening the front door also requires you to switch the touch screen to the door manual screen. After pressing the "open the front door" button on the touch screen, the vacuum pump and the electric ball valve act first, and the compressed air in the sealing groove of the front end box is extracted, and pull the sealant strip back to the sealing groove. After 15 seconds, the door motor moves (if the starting position of the door is not closed, the delay of 15 seconds is unnecessary). In the process of opening the door, if the door motor appears overcurrent protection, indicating that the door meets abnormal resistance in the opening process, the control system will automatically cancel the door opening operation, and prompt the corresponding information, as shown in Figure 4. During the opening of the front door, the front door status indicator light is flashing. When the door panel reaches the opening position, the front door indicator light is out, and the opening front door operation is completed, and the sealed door can be opened.
Open the door operation cannot be performed in the following cases:
① The internal compartment pressure is not between-10Kpa and 10Kpa. If the door is opened, the alarm screen shown in Figure 4 will appear:
Figure 4
The alarm is over after 5 seconds.

1) The following will be a brief introduction of the program operation procedures and the parameters setting situation commonly used by the device:
1.Fabric program running procedures and the setting of the parameters
The parameters of the fabric program have been preset in the PLC, and users cannot modify them themselves.
To achieve a satisfactory sterilization effect, each parameter is usually set at:
The number of pulsations:Three times
The sterilization temperature:134°C
The sterilization time:7 Minutes
Dry time: 20 minutes
The number of pulsations--The effect of pulsation is to force out the cold air in the sterilization room and sterilization items through the vacuum pump before sterilization. The amount of cold air exclusion determines the degree of uniformity of the temperature in the sterilization room, so as to determine the sterilization effect. The number of pulsation times and the size of the pulsation amplitude determine the complete air exclusion. According to the calculation, the pulsation can discharge the cold air in the sterilization room by more than 99.2% for three times.
The following table describes the operating state of each control valve and pump during this procedure. The work flow chart of the program is shown below:

6. Daily maintenance, repair and operation procedures of the equipment
The equipment is running normally without any fault, but it should be repaired after a certain time. The fault is not only related to the service life and internal quality of the equipment parts, but also related to the correctness of the use of the equipment and the daily maintenance. Many faults are caused by improper use, incorrect operation, and no attention to routine maintenance and regular maintenance.
The correct use and daily maintenance of sterilization equipment are necessary to extend the service life of the equipment and reduce faults. This chapter will provide a brief introduction to precautions and maintenance.
6.1. Equipment daily maintenance and maintenance
1)Equipment daily maintenance and maintenance
• Turn off the touchscreen power supply.
• Turn off the control power supplies and power supplies.
• Close the steam source valve. Close the steam valve into the sandwich, and the steam in the interlayer will naturally condense and drain from the sandwich trap.
• Close the compressed air valve or power off the air compressor.
• Close the water supply valve.
• Clean the inside of the sterilization chamber (inner chamber) and the sterilization vehicle.
When the temperature of the sterilization chamber and the sterilization vehicle drops to near room temperature, scrub it with a neutral detergent, then rinse it with tap water, and finally dry it with a barren cloth.
Clean up the fiber chips and sediment attached to the front and lower filter of the inner chamber to ensure that the vacuum rate, the smooth flow of condensate water and the temperature indication coincide with the pressure.
Warning The cleaning personnel should first enter the inner room, first close the emergency stop switch (power switch), and take the key of the switch with him before entering the inner room to work.
• When the sterilizer is not working, open the front door to prevent the sealing performance and service life of the door sealing ring due to long-term compression deformation.
• Check the door seal ring for damage and clean it with a clean soft cloth.
2)Routine maintenance of the main components
• Pneumatic corner seat valve: the pneumatic valve is a powerful on-off valve, all are imported high-quality valve, high reliability, when the use should pay attention to the impact of foreign bodies in the pipeline on the valve parts.
• Liquid ring vacuum pump: vacuum pump uses water ring seal for vacuum. Water rings seal and energy conversion. Because the exhaust has a lot of water in the discharge of steam, so the process of work should be constantly replenished water, but the water should not be too large, too large will increase the power loss of the pump, the working environment of the pump, the water according to the actual situation by the pump through the automatic absorption of the water tank. Water quantity and water temperature directly affect the vacuum rate and the life of the pump. The lower the water temperature, the higher the ultimate vacuum degree, and the general maximum requirement does not exceed 25°C. When stopping for a long time, you should open the pump bottom screw plug, put the pump memory water clean, and then block the water release hole, filled with saponification liquid. Otherwise, the pump is easy to rust or freeze crack pump body, affecting the pump efficiency and service life.
• Hydrobic valve (pneumatic corner seat valve, solenoid valve): the internal chamber exhaust pipe has a small corner seat valve for the internal chamber drainage, the sandwich exhaust valve has a small solenoid for jacket drainage, the drainage work is normal or not directly affects the sterilization effect. If the water cannot be discharged normally, the drain valve should be opened for cleaning. At work, a small amount of steam discharge is a normal phenomenon.
•Safety valve: Install one safety valve each in the jacket and the inner chamber. On the sterilization device to protect the equipment and personal safety, jacket safety valve installed above the cabinet, the inner chamber safety valve on the side of the cabinet, the opening pressure and back pressure has been adjusted when the factory, the user do not adjust to avoid accidents due to improper adjustment, but need to half a year to its hand pull several times, wash with steam, to prevent its parts for a long time not action corrosion, when sterilization overpressure safety valve working for some reason.
Warning Remember not to contact the safety valve handle directly by hand, use a screwdriver or tie a cloth to pull, to prevent steam damage to the operator!
• Pressure regulating valve (if optional): when leaving the factory, the inlet steam pressure regulating valve has been adjusted, the user if there are special requirements, can readjust. The two film boxes of the pressure regulator are prone to stretching or compression for a long time, easy to welding and corrosion, if found, steam leakage should be replaced in time.
• Debacterial air filter: the filter works in the vacuum breaking stage, and has the characteristics of high filtration accuracy, energy saving, safety and reliability. The gas filtration accuracy can effectively solve the repollution of the sterilized items after entering the air into the inner chamber, and the filter element can be used for one to two years in general.
• Filter: each steam inlet and the inlet pipe has a filter, its function is to filter out the impurities in the steam pipe and the inlet pipe, to ensure the subsequent pipeline and the reliable action of each valve, so it is necessary to be cleaned regularly to prevent blockage. When cleaning, screw out the lower plug, clean the filter screen, and then tighten the plug. In addition, one filter should be installed in front of the trap and the inner chamber trap. These two filters are crucial for the normal trap of the jacket and the inner chamber, so the filter should be removed and cleaned regularly.
• One-way valve (check valve): the door evacuation pipe is equipped with a one-way valve, which should be checked regularly, to avoid foreign bodies affecting its one-way sealing performance. The simplest way is to use the nozzle suction test after cleaning, no feeling of air leakage is normal.
• Solenoid valve: in order to make the solenoid valve work normally, the solenoid valve valve core and valve seat must be scrubbed once a season, to prevent the impurities in the pipeline from affecting its opening and closing.
Note: Check whether the solenoid valve is electric, you can use a screwdriver to test the nut on the valve head for magnetism.
• Condenser: pay attention to the quality of water, excellent water quality will condense a large amount of scale inside the condenser, will affect its condensation effect, so it should be chemical scaled according to the situation. For a long time shutdown, unscrew the lower part of the condenser, clean the water stored inside, and then plug the water hole.
3)Maintenance of the electrical components
• Electrical components and connections are strictly prohibited to contact with the water. If the water is accidentally stained with the water, the power supply should be turned on only after the treatment.
• It must be dust-proof and dust once a season.
• The plug seat of each connection, each plug element should be often checked for loose, loose should be tightened.
4)Removal of scale
Because the water quality in some areas is too hard, the long-term operation of the equipment will deposit a large amount of scale in the pump and in the pipeline, and the accumulation of scale will affect the normal operation of the equipment. It is recommended to use water sources that meet the boiler water standards or deionized water, and use all kinds of chemical descalers for comprehensive descaling treatment regularly (recommended once half a year).
Scaling process:
① Remove the water from the vacuum pump and the condenser first.
② There is a flange connection at the drainage outlet of the vacuum pump, remove the flange screw, pour the chemical scale removal agent into the vacuum pump from the vacuum pump, fill the vacuum pump, the condenser and the pipe connected with the inner chamber, and wait for about 4
