Analysis of structural characteristics of high and low temperature alternating test chamber
- 2019-07-05 -

High and low temperature alternating test chamber common fault 1 - overpressure

1, the heat transfer of the cooler is not very good, to organize the cooler

2, other refrigeration units common faults, looking for technical personnel to check

3. Query the value of the working pressure set by the pressure controller, usually 1.9 MPa. If it is lower, adjust it.

High and low temperature alternating test chamber common fault 2 - water stop

The meaning of water stop is that the humidifier has less water in the small water tank. The usual problems are:

1. A certain area of the water supply pipeline is plugged. Note that the water inlet pipe of the humidifier small water tank water level line is on the line.

2, water stop protection temperature controller should be set to 120 ° C, if slightly lower, adjust only

3. When the water is released, the water tank of the small water tank of the humidifier is not added to the special part.

High temperature and low temperature experiment common fault 3 - overheating

The high and low temperature alternating test chamber has a separate overheat protection temperature controller. The usual overheating alert problem is:

1. The temperature controller setting is too low. This type of fault belongs to the common operability fault. It is only necessary to increase the temperature controller setting. Most of the factory settings are 175 °C.

2, the dashboard display information temperature value significantly exceeds the set operating temperature value: it will be the temperature control component is broken down by heat, the common fault of the instrument panel or the common fault of the operation road, people should check and replace.

High and low temperature alternating test chamber overhaul:

If the high and low temperature alternating test chamber is abnormal during the whole process of testing, first check whether the operability is common. The resolution is based on the installation and application process. If there is any error with the verification, and the actual operation according to the instructions for use, In normal work, it is said that the operability is a common fault, and you can also find relevant professional and technical personnel to check.
