Supply original Maneurop reciprocating compressors, France and the United States gifted musicians compressor, refrigeration compressors, cold compressors, piston compressors, refrigerator compressors, refrigerant R22, models: MT100 MT120 like. Maneurop compressors come out for 35 years, closed, piston compressors for commercial refrigeration for the evaporation temperature: -45 ℃ - + 20 ℃, refrigerant: R22, R134A, R507, R404A, R502, R407, cold range: 700 · --71000W, mainly applied to air conditioning, industrial chillers, cold storage and so on. Variety, quality assurance, reasonable prices, fast service dried up, please call to discuss! Compressor Best Practices Guide ◆ system cleanliness ? To avoid compressor burned before using absolutely put all the soiled material is excluded from the system, such as water, metal debris, cleaning agents and chemicals. ? Before system assembly, all components must be removed by water and filled with nitrogen, and the use of clean annealed refrigeration grade copper pipe. · The system uses trichlorethylene after washing, must exclude residual trichlorethylene with dry air or nitrogen. ◆ welding method · To avoid oxidation caused by internal brass copper oxide film, when soldering copper pipe joints must be filled with low-pressure nitrogen gas in the tube and use the right amount of help welding flux. * You must all be thoroughly cleaned before welding the welding head and remove grease, brass and copper alloy welding flux need to use phosphor copper, brass and steel welding needs the use of silver-copper solder, oxyacetylene welding is the most appropriate tool . ◆ After the test is completed, drain systems, must be properly filled with dry air or nitrogen, do dwell action. ? Use electronic leak detector leak test is the best way. · Check for leaks using traditional way of course also available. ? Do not filled with air or R134A systems. ◆ An effective vacuum evacuated to exclude moisture from the system, and the vacuum level reaches 200 microns, it must be evacuated from both ends of the system. ? Use light bulbs or infrared heating system. · Brass connection must be thick and short · Use suitable capacity two-stage vacuum pump rotor can resist suction effect. ? Use electronic vacuum gauge measuring the degree of vacuum ? Do not use closed compressor vacuum, because it is unfit for evacuation purposes, but they can not achieve the degree of vacuum needs. ◆ refrigerant charging · any refrigeration system which uses refrigerant quality and quantity will absolutely affect the performance and reliability, you should use the original purchase refrigerant trusted brand, while adding refrigerant charge should be calculated using pounds, said filling volume. · Prepare several sets of hose, brass, valves, etc. are filled with different refrigerants, and do not use barrier plug filling, because it will damage the compressor. · Please use the refrigerant temperature and pressure chart to play the highest performance system applications. ◆ Compressor Installation ? Install the compressor feet, use proper torque bolts screwed into the gasket, head of the bolt should be on the sleeve and not on the shock-absorbing rubber grommets. ? To prevent leakage caused by vibration, mufflers and exhaust pipes should be made of suitable damping ring, the compressor should not be rigid in any way fixed. ? This type compressor is not suitable for use in travel and other means of transport. ◆ Electrical · Please feel free to check the compressor C & R pin voltage, the voltage of these endpoints should be within the allowable voltage range, if the power supply voltage is insufficient, please equipped with a dedicated voltage transformer stable, cut off power supply voltage is too low or too high or delay relay. · Please use the original supply of electrical parts. · For security reasons, grounding the compressor is necessary measures. ? All electrical connections must be secure at the same time have adequate insulation. Discussion industry complaints: complaints about the fact that the use of industry-specific tools or equipment that is caused on before replacing the compressor exclude the possibility of all of the above, extensive analysis to see if the system consistent with the normal function of the compressor. When replacing the compressor in the system do not understand the system real symptoms will lead to another compressor burned. Welcome to inquire. Tel: Haojing Li 13892896162,029-8325 6740
