Maekawa screw compressor overhaul
Thread Content
Maekawa screw compressor overhaul (MYCOM), SCV series, manual internal volume ratio adjustment, with refrigerant: Ammonia, fluorine, propane. Common models include: 160VLD, 160VMD, 160VSD, 200VLD, 200VMD, 200VSD, 250VLLD, 250VLD, 250VMD, 250VSD, 320VLD, 320VMD, 320VSD, 160VLG, 160VMG, 160VSG, 200VLG, 200VMG, 200VSG, 250VLLG, 250VLG, 250VLG, 250VSG. Among them, the tail of the model has a D exhaust port facing the direction of the shaft seal and a G exhaust port facing downwards. The inner volume ratio of the lower part of the shaft seal is manually adjusted, which can flexibly control the cooling capacity according to demand, and can also effectively prevent under-compression caused by a dirty condenser. Maekawa screw compressor overhaul case: The unit is a Beijing Tianli cascade refrigeration unit with R22 and R23 refrigerants and a temperature of -65 degrees Celsius. It is used in the pharmaceutical industry to provide cooling capacity for cephalosporin synthesis. Using Maekawa compressor head, the model is 200VLD. It has been running for a long time, the compressor has loud noise and vibration, and the running current is high, causing the unit to trip. Difficulty turning the car manually. We disassembled it and inspected it, and found that the rotor and bearings were damaged. Other parts also have some wear and tear. Replace necessary parts such as bearings, sealing rings, balanced piston kits, adjusting pads, sealing pads, and shaft seals. Keep the pressure normal, place the workbench to adjust the concentricity, and install the coupling. Add fluoride and debug until the unit meets the process requirements. Inspections will be carried out later to ensure the reliable operation of the machine.

Where is the overhaul? Looking at the pictures it is simply a new device.
You can’t see the details during on-site overhaul, so you need me to do it for you individually.
I won’t write in such detail next time
good. Very good information. Is this compressor skid mounted?
The cascade machine is divided into two skids, the low-temperature machine skid and the high-temperature machine skid. Water is used to liquefy the refrigerant of the high-temperature machine. The high-temperature machine refrigerant is used to liquefy the refrigerant of the low-temperature machine. The low-temperature machine is used to cool methylene chloride.
oh. Our screw machine is on a base. It's the first time I've seen this kind of two-piece crowbar. :lol
