The compressor is the core component of the chiller. Damage to the compressor is a serious fault and needs to be dealt with in time, otherwise the chiller will not work. Screw chillers are mainly used in chemical chillers, ink printing chillers, large energy equipment chillers, mixing station chillers, food preservation, central air conditioning and other industries.
According to different heat dissipation methods, there are air-cooled screw chillers and water-cooled screw chillers. The compressor of the screw chiller usually uses Taiwan Hanbell or Germany Bitzer compressors. This type of compressor uses 5:6 ultra-high-efficiency spiral rotor technology, which is 20-30% more energy efficient than ordinary compressors. However, even the best products cannot be used all the time.
It will also have a limited service life, and it may cause faults due to improper operation. So, when the screw chiller compressor is damaged and there is a problem, how should we deal with it? First of all, we need to analyze the cause of the compressor burning: whether it is a temperature control quality problem such as the contactor and overloader in the control box; whether the set value is changed or adjusted incorrectly.
Whether it is due to unstable power supply voltage; whether the operator operates in normal order, etc. It is important to identify the specific reasons to avoid re-burning after the new compressor is replaced. If it has been determined that the compressor is damaged and completely unusable, we should replace the new compressor according to the following steps.
