What to do if the screw chiller compressor is damaged

What to do if the screw chiller compressor is damaged The compressor is the core component of the chiller. Damage to the compressor is a serious fault that needs to be dealt with in time, otherwise the chiller will not work. Today, the editor will introduce the knowledge and process of handling damaged screw compressors. Screw chillers are mainly used in industries such as chemicals, ink printing, large-scale energy equipment, mixing plants, food preservation, and central air conditioning. According to different heat dissipation methods, there are air-cooled screw chillers and water-cooled screw chillers. The compressor of screw chiller is usually selected from Taiwan Hanbell or Germany Bitzer compressor. This type of compressor uses 5: 6 ultra-efficient spiral rotor technology, which is 20-30% higher than the general compressor energy efficiency. However, even the best product can not be used forever, it will have a limited service life, or it may cause malfunction due to improper operation. So, what should we do when the screw chiller compressor is damaged and there is a problem? ? First of all, we have to analyze the cause of the compressor burn-out: whether it is a temperature control quality problem such as contactors and overloaders in the control box; whether it is a set value change or adjustment error; whether it is due to unstable power supply voltage; whether the operator is in the normal order Operation etc. It is important to confirm what the specific cause is so as not to burn out 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 with the following steps. 1. Remove the filter drier and use a temporary removable tube or copper tube connector to catch the short-circuited part 2. Inject cleaning agent into the pipeline system to clean the circulation flow, if necessary, the cleaning agent can be replaced for multiple cleaning 3. Dry the entire system, then use nitrogen with a pressure of 10kg / cm2 to dry to no residual cleaning agent 4. Install a good compressor and drying filter, and use nitrogen with a pressure of 10kg / cm2 to detect leaks. If it does not leak, the remaining nitrogen can be discharged into the atmosphere from the high-pressure end angle valve 5. Simultaneously evacuate from the high and low voltage ends to 1000micro, and then check all power and electrical control systems 6. Add liquid refrigerant, start the test after reaching 80% ~ 90% refrigerant volume. (Note: The compressor needs to be heated for 2 hours) 7. Change the compressor refrigeration oil and observe the oil used when the compressor is running.
