Refrigeration equipment, how to clean
Release time:2016-09-07 16:24:57
In the normal course of life, doing us a great favor of refrigeration equipment. Smallhousehold refrigerator, large cold storage cold storage of fruits and vegetables, meat. Refrigeration equipment used to give us life and bring a lot of convenience. However, with increased storage and cold storage growth with time, in order to better preservation and refrigeration, and improve the service life of the refrigeration equipment, refrigeration equipment we need to be cleaned on a regular basis.
In a well-designed and properly installed refrigeration equipment, motor burned due to built-in motor insulation damage are rare. However if the device exists in high temperature and high pressure gas, decomposition of residual corrosion, acid and oil, the result (unless the first damaged valves or operating agencies working) will eventually lead to a built-in motor damage.
Compressor refrigeration equipment cannot be damaged by motor burned only a hasty cleaning. Otherwise, the replacement of the built-in motor will be subject to theprevious motor burned and left in the remnants of the device's influence once againburned to the ground.
In order to prevent the above from happening, describes several such devices cleaning steps
1. turn off the compressor stop valve, the device separate from the compressor to the rest. Removed without cut-off valve, the compressor, and install the replacementcompressor.
2. from a sample and hold some oil out of the compressor in the glass, so that uponcompletion of the cleaning can be used as a comparison.
3. turn the compressor stop valve, the device separate from the compressor to the rest. Removed without cut-off valve, the compressor, and install the replacement compressor.
4. check that all the control and switching devices, expansion valve, solenoid valve, safety valve, bypass valve, clean or replace if necessary, remove or replace all filter drier, the filter or filters must be cleaned or replaced. Oil sight glasses failure and should be replaced. Based on the output power of the device dry filter in suction piping install acid absorption, and installed on the liquid pipeline drying large capacity acidabsorption filters.
5. dry suction pipes of acid absorption filters and liquids pipeline drying large capacity acid absorption filters must be installed. Both specifications are according to thedevice's capacity may be.
6. the use of compressors and the system is running. Precipitation of residual dirt from the system will increase the dry filter pressure loss, up to every 4 hours to checkthe dry filter down to avoid measurement errors. To avoid this error, you should always check. If the pressure drop exceeds the figure of 31-33 maximum, replace filterdrier.
7. system operation after 48 hours, check the oil smell and color. If possible, use acid for the determination of acid content. If the lubricant has burned acidic or oil sight glasses show a higher moisture content, you should replace the filter drier and lubricants. System must be run again after 48 hours repeat the check of the above provisions. Run and check again until the lubricant pure tasteless, color and initial samples taken in the 2nd above is similar.
8. pipe on the liquid bulk dry filter into normal specifications. Should dismantle thesuction line filter drier. Such as use, it is reassembled.
9. in order to ensure smooth running in the future, all in cleaning completed and running again two weeks later to make an inspection.
