Service center "Compressor" performed maintenance of the ammonia refrigeration system such as chiller, namely repair of screw compressor Mycom 200 VLD (Mayekawa)
Regardless of the level of danger of working with ammonia, it is a common choice of refrigerant in very large cooling systems, as in this case with the dairy “Galicia”.
There are three main reasons for choosing ammonia as a refrigerant:
• The physical properties of ammonia make it effective and efficient for large systems.
• It quickly collapses in the environment, minimizing potential environmental impacts.
• Any spill or accidental release can be quickly identified due to a strong and pungent odor (ammonia).
The risks associated with ammonia cooling can be significantly reduced through careful management, maintenance and scheduled repairs.
Part of this process is the clear marking of the pipes and equipment used.
Checking the ammonia refrigeration unit, complete diagnosis and analysis of the compressor.
Replacing parts such as:
• mechanical seal
• potentiometer with microswitch,
• set of thrust bearings,
• set of gaskets and seals,
• retaining ring with oil sealing sleeve,
• set of lock and torsion washers,
• oil cleaning filters...
Removal and installation of the discharge indicator for the correct functioning of the mechanism and the definition of a safe method when servicing this part of the compressor.
An important and significant part of the cost of maintenance and repair of screw compressors is the replacement of a set of thrust bearings and the installation of a shaft seal. Therefore, this part of the service is very delicate, and it is important that this service be performed correctly.
Using only special tools, the engineers of the Service Center "Compressor" was carefully executed:
• measurement and adjustment of gaps,
• check and alignment of shafts,
• assembly and start-up of the unit.
This is only a part of the services that were demonstrated by our specialists, serving the TM “Galichina” dairy plant in the town of Radekhov Ukraine. Over time, the COMPRESSOR SC from NPP Promtechgroup only strengthens the credibility of the company's image.
We will ensure the long-term operation of your refrigeration equipment!
