Many people may get confused about the abnormal conditions that occasionally appear in the high and low temperature test chambers. Here are the professional engineers who will explain to us how to deal with the abnormal conditions of the high and low temperature test chambers. The following table will let you Clearly understand, everyone can simply check in.
Fault phenomenon
the reason
The whole machine cannot be started
1. Is the connection contact good? 2. Is the power supply line (phase sequence relay) phase sequence connected correctly? Is it burned and damaged? 3. Contactor or relay contact is good / burned or damaged
Abnormal heating system
1. Execution component contactor, relay contact is stuck or burned out / SCR, solid state relay is broken down 2. Controller, regulator, electric contact thermometer control is good / burned or damaged
Slow heating
1. Is the instrument setting correct? 2. Is the resistance of the total resistance of the heating component normal? Is there a short circuit or an open circuit? 3. Is the blast system operating normally/steering correct?
The compressor is working abnormally
1. Is the cooling switch open/contacted? Is it burnt or damaged? 2. The meter shows whether it is normal/whether there is output 3. Is the solenoid valve control normal/burned damaged?
Abnormal blast system
1. The motor does not turn 2. The blower switch is open / burned and damaged 3. The starting capacitor (single phase) is burned and damaged
The instrument works abnormally
1. Setting abnormality: whether the setting is correct/the instrument is bad 2. No output: whether the setting is correct/the instrument is bad 3. Malfunction output: Whether the platinum resistance wire connection is good/bad or the instrument is bad
