温度变化对制冷压缩机的造成哪些影响?

医药冷库设计温度对制冷压缩机的影响
The influence of the design temperature of the medical cold storage on the refrigeration compressor
夏季情况下,压缩机的排气温度是比较高的,手是不能够触摸,按照国家标准规定,R22的制冷系统的排气温度应该不会超过150摄氏度,超过这个温度线属不正常状况。
In summer, the exhaust temperature of the compressor is relatively high, and the hand is not able to touch. According to the national standard, the exhaust temperature of the refrigeration system of R22 should not exceed 150 degrees Celsius, exceeding this temperature line is abnormal.
排气温度超高原因是压缩机的吸气温度超高,或是冷凝温度超过所造成,必须引起注意。排气温度过低,手摸排气管不烫手,这说明吸气温度特别低,压缩机可能湿行程运行或系统工质相当少的运行状态。压缩机湿行程容易损坏阀结构;制冷剂特少情况运行,会影响电动机的绕组散热,加速绝缘材料的老化。

The cause of ultra high exhaust temperature is that the suction temperature of the compressor is super high, or the condensation temperature exceeds that. It must be paid attention to. The exhaust temperature is too low, and the handle of the exhaust pipe is not hot. This shows that the suction temperature is very low, and the compressor may run in wet running or with relatively few working fluids. The wet stroke of the compressor is easy to damage the structure of the valve, and the operation of the refrigerant will affect the cooling of the motor's winding and accelerate the aging of the insulating material.

机壳温度变化对压缩机和制冷系统的影响
The influence of the temperature change of the casing on the compressor and the refrigeration system
机壳温度过高的影响及原因
The influence and reason of the high temperature of the shell
机壳表面温度超过正常范围,主要是制冷系统的吸气温度过高(高于15摄氏度)。过高的热蒸气进入压缩机,吸收机壳内热量后,使蒸气的温度更高,从而使机壳的温度上升。过热蒸气的温度上升很高,机壳的温度也升得很高,对油的冷却不利,这会影响运动零件的润滑,加速磨损,另外还会引起排气温度上升。
The surface temperature of the shell is more than the normal range, which is mainly the high suction temperature of the refrigeration system (higher than 15 degrees centigrade). Excessive heat vapor enters the compressor and absorbs heat in the casing, which makes the temperature of the steam higher, thus increasing the temperature of the shell. The temperature of superheated steam rises very high, and the temperature of the shell rises too high, which is unfavorable to the cooling of the oil. This will affect the lubrication of the moving parts, accelerate the wear and increase the exhaust temperature.
机壳温度过低的影响及原因
The influence and reason of the low temperature of the shell
机壳表面温度低于正常范围,其原因是吸气温度太低(低于15摄氏度)。它对冷冻油和电动机绕组的冷却都有利,但制冷量有所下降。当吸气温度特别低时,会使大半只机壳结露,就有液击的危险,这是对压缩机的严重打击,应该特别注意。同事冷冻油内溶解大量的制冷剂,不利于运动零件的润滑。
The surface temperature of the shell is lower than the normal range, the reason is that the suction temperature is too low (less than 15 degrees centigrade). It is good for cooling oil and cooling of motor winding, but the cooling capacity has decreased. When the suction temperature is very low, most of the shell will be exposed and there is a danger of liquid shock. This is a serious blow to the compressor. It should be paid special attention to. A large number of refrigerants are dissolved in the refrigerated oil of the colleague, which is not conducive to the lubrication of the moving parts.
一般消费者检测半封闭制冷压缩机温度的方法都是采用手感,因为使用温度计的话不是很方便,如果发现半封闭制冷压缩机的使用出现不正常的温度,就需要及时进行处理。
The way that a general consumer detects the temperature of a semi closed refrigerating compressor is to use the handle, because the use of thermometer is not very convenient. If we find that the abnormal temperature of semi closed refrigerating compressor is abnormal, we need to deal with it in time.
