The solution to the problem of non cooling in vertical low-speed centrifuges requires comprehensive analysis from multiple perspectives. The following is a detailed description of the problem and possible solutions:

1、 Possible reasons for non cooling of vertical low-speed centrifuge

1. Compressor malfunction

Compressor damage: The compressor is the core component of the centrifuge refrigeration system. If the compressor malfunctions or is damaged, it will directly lead to a decrease in refrigeration efficiency or failure to cool.

Compressor startup issue: The compressor cannot start normally, which may be due to electrical control failure or insufficient power supply.

2. Refrigerant leakage

Insufficient refrigerant: If refrigerant leaks in the refrigeration system, it can lead to a decrease in refrigeration efficiency or failure to cool.

Refrigerant pipeline rupture: Refrigerant pipeline rupture or poor connection can also cause refrigerant leakage.

3. Condenser malfunction

Condenser blockage: If the condenser is blocked by dust, dirt, or other impurities, it will affect its heat dissipation effect, leading to a decrease in cooling efficiency.

Condenser fan malfunction: If the condenser fan is damaged or has insufficient speed, it can also affect its heat dissipation effect.

4. Control system malfunction

Temperature sensor malfunction: If the temperature sensor is damaged or fails, it will cause the control system to be unable to accurately sense the temperature of the refrigeration system, thus making it impossible to perform effective control.

Control system circuit failure: If there is a malfunction or poor contact in the control system circuit, it can also cause the refrigeration system to malfunction.

5. Power supply issues

Insufficient power supply: If the power supply of the centrifuge is insufficient or the voltage is unstable, it can also affect the normal operation of the refrigeration system.

Loose power plug: If the power plug is loose or poorly connected, it can also cause the centrifuge to fail to cool properly.

2、 Solution for non cooling vertical low-speed centrifuge

1. Check the compressor

Replace compressor: If the compressor is damaged, a new compressor needs to be replaced. When replacing, ensure that the new compressor matches the prototype number.

Check the starting circuit of the compressor: If the compressor cannot start normally, it is necessary to check whether the starting circuit is working properly.

2. Check the refrigerant

Supplement refrigerant: If the refrigerant is insufficient, sufficient refrigerant needs to be added to the refrigeration system. When supplementing, the same refrigerant model as the original system should be used.

Check and repair the refrigerant pipeline: If the refrigerant pipeline is broken or poorly connected, it needs to be repaired or replaced.

3. Check the condenser

Cleaning the condenser: If the condenser is clogged, it is necessary to clean the dust and dirt on top. You can use a hair dryer or vacuum cleaner for cleaning.

Check and repair the condenser fan: If the condenser fan is damaged or has insufficient speed, it needs to be repaired or replaced.

4. Check the control system

Replace temperature sensor: If the temperature sensor is damaged or malfunctioning, a new temperature sensor needs to be replaced.

Check and repair the control system circuit: If there is a malfunction or poor contact in the control system circuit, it needs to be repaired or replaced.

5. Check the power supply

Ensure stable power supply: If the power supply is insufficient or the voltage is unstable, measures need to be taken to ensure stable power supply. For example, voltage regulators can be added or the power supply system can be upgraded.

Check and tighten the power plug: If the power plug is loose or has poor contact, it is necessary to tighten the plug and ensure good electrical connection.
