Maintenance Methods of Semiconductor Performance Test Chiller

The semiconductor performance test chiller can provide users with a field source with controlled thermal cooling and uniform constant temperature, and can also be used as a heat source or cold source for direct heating, cooling, auxiliary heating, and auxiliary cooling, and temperature control within the full range. It is used in chemical reaction process control such as petrochemical and pharmaceutical, semiconductor diffusion furnace diffusion process control, constant temperature temperature control or external circulation application in reaction kettle, automatic synthesis instrument, extraction and condensation device.

1. Check whether the fastening bolts of the power wiring are loose. Whether the high and low pressure values of the refrigeration/heating system are normal. Whether the running current of the compressor and the insulation resistance of the unit are normal.

2. Whether the running current of the compressor and the insulation resistance of the unit are normal.

3. Check whether the filter drier and sight glass are normal. If the outlet of the filter is frosted, it means that the filter is dirty and blocked. The filter screen needs to be cleaned.

4. Whether the compressor lubricating oil is normal, if the oil level is lower than 2/3 of the sight glass during operation, add lubricating oil. If it is polluted or deteriorated, the lubricating oil should be replaced, and the oil filter should be cleaned or replaced. Replace filter drier cartridge.

5. Since the volume flow rate of the coolant will be affected under the condition of insufficient pressure, the higher the pressure of the pump, the more stable the flow rate.

6. The design of the refrigeration circuit and the temperature control of the components. When the temperature of the heating liquid rises to the set value, it can quickly and effectively prevent the temperature from continuing to rise.

Then, users are required to do a good job of recording during the use process to avoid failures and problems that cannot be found and solved in time, and at the same time do maintenance work to ensure that the equipment can reach a good operating state.
