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
