Sterilizer common malfunctions and Alarm list

Common malfunctions
no. trouble cause The elimination method
1 The cabinet body water remained Vacuum pump, vacuum valve switch out of sequence Operate according to the use of sterilizer operating guide manual
The air return inlet water disk block Dredge
The water in the steam water separator is not eliminated Drainage
during the Humidifying water entered  inspection The steam pressure of steam generator, controlling the wetting velocity
condensed water too much residual in the Steam filter Open the steam filter sewage outlet discharge water
2 Cabinet air leakage Door strip aging, damage Replace door strip
Door seal groove debris removal of debris
The failure of  safety valve Send inspection institute for maintenance
relevant valve,pipe leakage fasten again or replace
3 Vacuum pump does not work Circuit breaker trip Find out the cause, repair
Thermal relay protection Pump working current is too large, should stop work, find out the reason, overhaul
4 Vacuum pump Water Leakage water Seal sealing ring damage replace
Flange loose fasten
5 Vacuum pump abnormal sound lack of water or the water is too small Check the vacuum pump water supply
 the vacuum valve not Open Open the vacuum valve
There is debris in impeller cavity Remove debris
6 The  Water pump Leakage The sealing ring is damaged Replace sealing ring
7 water Pump do not work Circuit breaker trip Find out the cause, repair
Thermal relay protection Pump working current is too large, should stop work, find out the reason, overhaul
8 Vacuum pumping speed too slow vacuum pump Lack of water or water  is too small Check the vacuum pump water supply
The cabinet is provided with leakage Locate the leak point, repair
making vacuum system leakage Find vacuum pipeline leak points, fastening
9 EO cannot be added eo feeding pipeline plugging Dredge
The ambient temperature is too low EO cylinder insulation
10 Temperature raise is too slow circuit break of electric heating tube To repair the circuit of electric heating tube
Water tank temperature is too low According to the instructions for use in operational guidelines re-setting tank temperature value
11 Temperature, humidity, pressure display inaccurate or out of control Sensor damage change
Sensor supply voltage is insufficient Find out the reason, replace
12 IPC cannot normally start or work Fault of industrial control computer system Looking for industrial computer manufacturer or IPC professional repair personnel to repair
Viral infection Use antivirus software kill the virus
Memory bar loose Open the case to insert memory bar again
13 The door cannot be opened
 
The air pressure of air source  is not enough check air pipe pressure
Throttle valve failure adjust or change
Sterilized goods expansion extrude door wait the products cooled and shrink
Cylinder solenoid valve failure replace
Mechanical obstruction
 
Check the door moving parts is flexible, or effectively adjust or repair
14 The door cannot be closed The air pressure of air source  is not enough check air pipe pressure
Throttle valve failure adjust or change
Cylinder solenoid valve failure replace
Mechanical obstruction Check the door moving parts is flexible, or effectively adjust or repair
15 Door seal can not inflate Door sealing electromagnetic valve is damaged Repair or replace
Position switch failure Adjust or replace
The door is not closed in place Check the obstacles
16 Door cylinder leakage The damage of the sealing ring replace
Cylinder joint loosening fasten
17 Internal circulation system does not work Fault of magnetic transmission device Check the magnetic transmission device
The pipeline is not smooth  clean the pipe
