Short-range molecular distillation apparatusDuring use, some common faults may be encountered, and different solutions can be taken for different problems. Here are some common faults and their solutions:
1. The device cannot start or runs unstably
Possible reasons:
-Power issue: The power cord or plug is loose and the power supply is not connected.
-Equipment switch malfunction: The switch or circuit may have malfunctioned.
-Vacuum system malfunction: The vacuum pump or related pipelines have leaks or malfunctions, making it impossible to maintain a good vacuum environment.
resolvent:
-Check power supply: Ensure that the device is powered on, the plug is securely plugged in, and the power switch is functioning properly.
-Check the circuit: If the power is connected normally but the device still cannot start, check the circuit control board or related switches of the device to ensure that they are not damaged.
-Check the vacuum system: Ensure that the vacuum pump is working properly and that there are no leaks in the connecting pipes. If there is a leak, check the pipeline joints and sealing components, and repair or replace them.
2. Temperature too high or too low
Possible reasons:
-Temperature controller malfunction: The temperature controller or temperature control system malfunctions, causing the heating or cooling equipment to be unable to accurately control the temperature.
-Abnormal heating system: Components such as heating tubes and heating plates are damaged or have poor contact, resulting in unstable temperature.
-Condenser problem: If the condenser has poor heat dissipation or poor fluid flow, it may cause the condensation temperature to be too low or too high.
resolvent:
-Check the thermostat: calibrate the thermostat to ensure it is working properly. If the thermostat is found to be damaged, it needs to be replaced.
-Check the heating system: Check if the heating elements are working properly and ensure that there is no damage. If the heating is uneven, the heating plate can be cleaned or the heating element can be replaced.
-Check the condenser: Ensure smooth fluid flow and good heat dissipation in the condenser. If the condenser is blocked, it needs to be cleaned or replaced.
3. Insufficient or difficult to maintain vacuum degree
Possible reasons:
-Vacuum pump malfunction: The vacuum pump may not be working properly and unable to maintain the required vacuum level.
-Vacuum system leakage: There may be leaks in the vacuum pipes, joints, seals, and other parts of the equipment.
-Pipeline blockage or dirt: Vacuum pipelines may be affected by material residue or blockage, which may affect the vacuum effect.
resolvent:
-Check the vacuum pump: Confirm that the vacuum pump is operating normally and ensure that the suction of the pump is sufficient. If the vacuum pump malfunctions, it needs to be repaired or replaced.
-Check sealing: Carefully inspect the vacuum pipes, joints, and sealing components of the equipment to ensure that there are no leaks. If a leak is found, repair or replace the seal immediately.
-Clean the vacuum pipeline: Clean any blockages inside the vacuum pipeline to ensure smooth fluid flow.
4. Poor condensation effect
Possible reasons:
-Poor heat dissipation of condenser: scaling on the surface of the condenser or insufficient cooling water flow, resulting in poor condensation effect.
-Improper setting of condensation temperature: If the condensation temperature is set too high, it may result in ineffective condensation of steam.
-Condenser leakage or damage: The condenser may have cracks or poor sealing, causing the condensed gas to be unable to effectively reflux.
resolvent:
-Cleaning the condenser: Regularly clean the surface of the condenser to prevent dirt accumulation and affect heat exchange efficiency. Suitable cleaning agents can be used for cleaning.
-Adjust the condensing temperature: Check the setting of the condensing temperature to ensure it is suitable for the current distillation requirements. If the temperature is set improperly, adjust it to a reasonable range.
-Check the sealing of the condenser: Check if the condenser joints and seals are intact to ensure there are no leaks. If there is damage, the seal needs to be replaced.
5. Materials are not separated or the separation effect is poor
Possible reasons:
-Excessive or insufficient evaporation temperature: If the evaporation temperature is not appropriate, it may result in poor separation efficiency.
-Damage to separation equipment: The evaporator, condenser, or other critical components may be damaged or accumulate scale, affecting the separation efficiency.
-Mismatch in material properties: The difference in boiling points of the materials is small, which may result in unsatisfactory separation efficiency.
resolvent:
-Adjust evaporation temperature: Based on the properties of the material, adjust the temperature of the evaporator to a suitable range to improve separation efficiency.
-Check separation components: Check key components such as evaporator and condenser to ensure that they are not damaged or blocked. If there is a problem, repair or clean it.
-Check the properties of the material: If the boiling point difference of the material is small, it may be necessary to change the operating method, such as increasing the vacuum degree, increasing the number of fractionation layers, etc.
6. Abnormal noise or vibration of the equipment
Possible reasons:
-Vacuum pump or motor failure: The vacuum pump or motor is not working properly, which may cause increased noise and vibration.
-Unstable installation of equipment: Unstable placement of equipment may cause unnecessary vibration during operation.
resolvent:
-Check the vacuum pump and motor: Check if the vacuum pump and motor are running smoothly and if there are any abnormal noises. If a malfunction is found, it needs to be repaired or replaced.
-Adjust equipment position: Ensure that the equipment is installed on a stable ground to avoid vibration caused by unevenness.
When a short-range molecular distillation instrument malfunctions, each part of the equipment should be gradually inspected according to the specific situation, the root cause of the malfunction should be identified, and targeted solutions should be taken. Maintenance is the key to ensuring the long-term stable operation of equipment. Regular inspection and cleaning of various components, especially the condenser, vacuum system, and heating system, can effectively prevent most malfunctions from occurring.
