1, the temperature field of the full enclosed reciprocating piston compressor casing can be divided into two parts: the A. is affected by the inhalation steam, the temperature is low, it is in the micro heat or a slightly cool range. It is estimated at about 30, and the surface of the local casing around the suction pipe may be exposed. Under the B., the heat generated by the motor inside the cabinet and the frictional heat generated by the refrigerated oil are mainly carried out of the steam by the steam. www.ahyaohui.com
2, the influence and reason of the low temperature of the case are: the surface temperature of the chassis is below the normal range, the reason is that the temperature of the suction is too low (below 15 degrees Celsius). It is beneficial to chilled oil and motor winding cooling, but the cooling capacity has decreased. When the suction temperature is very low, it will cause more than half of the shell to dew. It will be dangerous to the liquid blow. This is a fatal blow to the compressor, so we should pay special attention to it. At the same time, a large number of refrigerants are dissolved in the refrigerated oil, which is not conducive to the lubrication of moving parts.
3, the influence and reason of the excessive temperature of the chassis are: the surface temperature of the chassis exceeds the normal range, mainly due to the high suction temperature of the refrigeration system (above 15 degrees Celsius). Too high heat vapor enters the compressor and absorbs the heat inside the shell, so that the temperature of the steam is higher, so that the temperature of the shell rises. The temperature of the superheated steam rises very high, the temperature of the shell is also rising very high. It is unfavorable to the cooling of the oil. This will affect the lubrication of the moving parts and accelerate the wear and tear. It will also cause a rise in the exhaust temperature.
