Why is the discharge temperature high in my Hanbell RC2-310B?
- R
  Rhonda Mcconnell MDAug 15, 2025
  High discharge temperature in a Hanbell Air Compressor can stem from several issues: * Insufficient refrigerant: Check for leaks, add refrigerant, and adjust suction superheat to less than 10°K. * Condenser problems: Inspect and clean the condenser to ensure proper heat exchange. * Refrigerant overcharge: Reduce the amount of refrigerant. * Air/moisture: Purify refrigerant and vacuum system. * Expansion valve issues: Adjust suction superheat. * Insufficient lubrication oil: Add oil. * Damaged bearings: Change the bearings. * Improper Vi value: Change the slide valve. * Lack of system cooling: Install liquid injection or oil cooler.

What to do if Hanbell RC2-310B Air Compressor motor thermistor / sensor trips suddenly?
- J
  james34Aug 18, 2025
  If your Hanbell Air Compressor experiences a sudden trip of the motor thermistor or sensor, it could be due to several reasons: * Low suction pressure: Install liquid injection to the motor coil. * Refrigerant shortage: Charge refrigerant. * Clogged suction filter: Clean the filter. * High suction temperature: Install liquid injection to the motor coil. * High suction superheat: Adjust the superheat to less than 10°K. * Unstable electricity: Check the electricity power supply.

How to fix abnormal vibration and noise in Hanbell RC2-310B Air Compressor?
- B
  Becky KhanAug 21, 2025
  Abnormal vibration and noise in your Hanbell Air Compressor can arise from: * Damaged bearings: Change the bearing. * Liquid compression: Adjust proper suction superheat. * Rotor friction: Change screw rotors or/and compression chamber. * Insufficient lubrication oil: Add oil. * Loosen internal parts, friction between slide valve and rotors, external debris: Dismantle the compressor and change the damaged parts. * Electromagnetic sound of the solenoid valve: Check. * System harmonic vibration: Check the system piping and if possible improve it using copper pipe. * Motor rotor rotates imbalance: Check and repair.

Why does my Hanbell RC2-310B fail to start or have Y-Δ starter shifting failure?
- M
  marshjoshuaAug 25, 2025
  If your Hanbell Air Compressor fails to start or the Y-Δ starter shifts incorrectly, consider these potential causes: * Slide valve piston issue: Check if the unloading SV is energized once the compressor shuts down. Unload the compressor before shot down. * Incorrect voltage: Check the power supply. * Voltage drop/contactor failure/phase failure: Check the power supply and the contactor. * Motor breakdown: Change the motor. * Incorrect power connection: Check and re-connect. * Y-Δ timer failure: Check or replace. * Closed valve: Open the stop valve. * Improper Y-Δ wiring: Check and re-connect the wiring. * Rotor locked/Earth fault: Check and repair. * Protection device trip: Check.

What causes oil loss in a Hanbell RC2-310B?
- M
  michael67Aug 28, 2025
  If your Hanbell Air Compressor is losing oil, possible causes include: * Lack of refrigerant: Check for leaks and add refrigerant. * Improper system piping: Check and correct the piping or install an external oil separator. * Liquid fills back: Maintain suitable suction superheat at compressor.

Why is my Hanbell Air Compressor unable to load?
- S
  Sally YoungAug 31, 2025
  If your Hanbell Air Compressor is unable to load, consider the following: * Low temperature/high oil viscosity: Turn on the oil heater before compressor start. * Clogged capillary: Clean or replace capillary. * Solenoid valve issues: Clean/purge the valve core or replace the coil. * Clogged oil line: Check and clean the compressor oil circuit. * Piston issue: Change piston or piston ring. * Clogged oil filter: Clean oil filter (replace if needed). * Small pressure differential: Minimum pressure differential is 4 bar. Consider to install an oil pump.

What causes a Hanbell RC2-310B Air Compressor to be unable to unload?
- B
  bradrogersSep 4, 2025
  If your Hanbell Air Compressor is unable to unload, it could be due to: * Modulation solenoid valve clogged or burnt: Clean or replace the solenoid valve. * Worn/broken piston rings or damaged cylinder: Change piston (if cylinder damaged severely, change the cylinder). * Insufficient lubrication oil: Add oil if necessary. * Leakages at internal discharge cover plate end side: Check or replace the gasket and tighten the bolts. * Solenoid valve voltage misused: Check the control voltage. * Piston stuck: Change the piston set, and check the cylinder and slide valve. * Capacity control logic unsuitable: Check.
