Beijing QINSUNRing trial you how to exclude a wet heat test chamber

The constant temperature and humidity test chamber is a more commonly used equipment in an environmental test. Below we will make a summary of the questions that everyone can encounter, helping you solve some frequent small problems that have encountered when using a constant temperature and humidity test chamber.

No heating: Whether the connection contact is good again
Instrumentation Displays whether or not there is an output repair / replacement
Instrument settings correctly reset
Why is the blowing switch open / Burning damage / contactor is turned on or burnback re-opening / replacement
Whether the heating switch is open / contact is good / whether burn damage open / repair / replacement
Execute elements (contactor, relay, thyristor, Solid state relay) Whether there is an output replacement Execution element (heating tube
, heating wire) whether burn damage to change
controller, regulator, and electrical contact thermometer control whether it is good / whether burn damage repair / replacement ]
Heating is not controlled:
Instrument display / control whether the normal maintenance / replacement
The instrument setting is correct / whether it is manual output reset
Execute the component contactor, the relay contact is adhesive or burned Bad / thyristor, solid state relay breakdown to replace
Execution element heating tube, welding wire whether it is maintenance / replacement
controller, regulator, and electrical contact thermometer control, whether it is good / burn damage repair / replacement

No humidity:
Whether the connection is good to re-reconnect
Instrumentation display normal / whether there is an output repair / replacement
Instrument settings correctly reset
Humidity switch is open / Contact whether there is good / whether it is burned damaged open / repair / replacement
Does the actuator (contactor, relay, thyristor, solid state relay) have output replacement
Does the actuator heating tube burn damage to change
Water supply Whether the system is normal / whether there is a wet water indication / repair

Humidity is not controlled:
Instrument display / control whether the normal maintenance / replacement
Instrument settings correctly / is it a manual output to reset ] Execute component contactors, relay contacts are adhesive or burn-up / thyristor, solid state relays breakdown to replace
Does the actuating tube is maintenance / replacement

Heating:
The instrument setting is correctly resetting
The total resistance resistance value of the heating component is normal / whether there is a short circuit, the open service / replacement
The blowing system is running normal / steering proper adjustment / repair

Moisture and slow :
Instrument settings are correctly reset
Hand-humidity component total resistance resistance is normal / yesNo short-circuit, open circuit repair / replacement
Whether the water control system is normal / floating ball is drain repair / replacement

Refrigeration work is abnormal:
Whether the connection is good to reconnect
meter display Whether or not there is an output repair / replacement
Instrument settings whether the
refrigeration switch is resetting: whether it is good / if you burn damage to / maintenance / replacement
Does the replacement of the component contactor good / Burning damage / whether there is an output replacement
pressure controller pressure adjustment, temperature controller temperature adjustment does not correct / burn damage to rear adjustment / replacement
Insurance contact is good / whether burn damage to reinstall / replace the maintenance core (seat )
Whether the compressor works normally / burn damage repair / replacement
Whether the solenoid valve control is normal / whether it is burned damage repair / replacement
Whether the air-cooled system is operating normally / turned to adjust / repair
Water-cooled system water pressure, water temperature is normal adjustment

Dehumidification work is abnormal:
Whether the connection is good to re-reconnect
The meter shows whether or not there is an output repair / replacement
Instrumentation Correctly resetting
Whether the wetting switch is opened / exposed, whether it is good / burn damage to open / repair / replacement
Does the component contactor have good / whether burn damage / whether there is an output replacement
Is the compressor work is normal? / Whether burning damage repair / replacement
Pump operation is normal / steering whether it is correct adjustment / repair

I hope to better master the comprehensive constant temperature and humidity test box maintenance knowledge in the process you use. Make sure the instrument is running normally! In fact, many times we will complicate simple questions. Many technical problems only need some small knowledge, and tips can be easily solved.
