All kinds of refrigeration oil performance contrast

Naphthenic base oil frozen
Naphthenic base oil chemical stability frozen, not with refrigerant or other materials react to exist in the system.Its thermal stability is good, in the hot section of the discharge valve does not accumulate carbon sediment.Wax content is low, in the cold parts of the system, can prevent oil and refrigerant mixture flocculent precipitate on the surface of wax and block system.Low pour point, preventing oil precipitation and solidification in the pipe.Dielectric insulation intensity is high, can ensure good insulation performance.Oil viscosity is moderate, were diluted with coolant can still keep the strength of the oil film lubrication.At the same time, in a very low temperature conditions, can still maintain liquidity.Applicable to the R11, R12, R13B1, R113, r22®, R114, R600a refrigerant, etc.

Ester synthesis freezing oil
Ester synthesis freezing oil between the CFC refrigerants and high stability.Especially for R22 in very low temperature has good solubility, and the broad viscosity range.The selection of high viscosity level in the rotary compressor has very good performance.Work high viscosity can be generated between the rotor good sealing, and can provide good lubrication in the middle of the bearing and sealing elements.Under low temperature condition, with good solubility and ensuring that the oil bath evaporator good oil return, and has good heat exchange efficiency.In addition, but also has very low volatile and good oil and gas separation.

Polyether type synthetic refrigeration oil
Polyether type of synthetic refrigeration oil is the most suitable for HFC refrigerants (everything), in the automotive air conditioner refrigeration system can give full play to the best performance.The product has excellent lubricity, chemical stability, water stability and low temperature fluidity, therefore in the use of refrigeration system performance to maintain the long-term stability, the refrigeration compressor working temperature range, and everything has excellent solubility, won't produce phase separation, can improve the working efficiency of the compressor.Compared with other products, such as polyol ester will produce the series of problems, such as corrosive acid and PAG even when exposed to high temperature and high humidity environment, rarely produce degradation.

Alkyl benzene synthetic refrigeration oil
Fully synthetic alkyl benzene frozen oil, has good low temperature property, oxidation stability and thermal stability.Suitable for CFC, as, carbon dioxide and ammonia as refrigerant air conditioning and refrigerating machine, etc, also can be used with contain as mixed refrigerants.

Freezer lubricating failure and countermeasures
(1) the lubrication oil pump pressure, pressure regulating failure and violent oscillation pressure gauge pointer
Freezer lubricating system normal work is: the main oil pressure gauge indicating stability;In the crankcase oil temperature should be kept between 10 to 65 ℃, optimum working temperature of 35 to 55 ℃;In the crankcase oil level should be high enough, and should be stable for a long time.Oil filter filter should not be blocked and differential pressure transmitting of fine oil filter should be blocked transmitting instructions.
Lubrication oil pump pressure, pressure regulating failure and pressure gauge pointer violent oscillation, the main reason is: the CPC temperature is too low, crank case, refrigerator oil pump imported oil filter mesh, filter blocked, and the oil level is too low, the oil pump oil absorption is difficult, cause air absorptionPhenomenon;Oil pump work for a long time, the wear of the pump is serious, internal leakage is too large, significantly lower volume effect;Pressure regulating valve core is stuck in the open position or pressure regulating valve spring failure;Serious leakage system.

In order to solve the above problems, can take the following measures:

• according to provisions of frozen oil index of oil change regularly check oil, replace or supplement the new oil filter.
• regular replacement or cleaning filter, pipeline and crankcase.
• Observed in daily check the oil level, oil temperature, oil pressure is normal.

Which should be paid attention to when, overhaul in the check and adjust the end clearance of oil pump, the pump should be replaced when necessary.Pump end clearance of different depending on the size of the product standard is about 0.03 ~ 0.08 mm, specific values and see about pump assembly technology requirements and delivery requirements.

(2)"Ice plug" phenomenon and prevent the refrigeration system

"Ice plug" phenomenon is due to the freon system for various reasons and mixed with water, where the temperature is lower than 0 ℃ ice, pipe blockage.In the "ice plug", expansion valve of high pressure liquid refrigerant, cannot pass ball valve and evaporate into low pressure, low temperature evaporation of refrigerant.In this way, the evaporator can not get enough steam too cold, of course there would be no air conditioning sent out.

"Ice plug" is due to the moisture into the air conditioning system.Refrigerator oil mixed with water, in addition to causing viscosity is reduced, cause corrosion to metal, will there be any freon refrigeration system cause the phenomenon of ice jam.
Such as improper operation of maintenance, vacuum is not complete, and the moisture content is more in the refrigerant or frozen oil, can make water into the system.In order to remove moisture, installed on the system for liquid filter drier, the small amount of water in the desiccant can be absorbed into the system.But if too much water into the system, can disable desiccant, resulting in "ice".
