上海春普浅谈机壳温度变化对压缩机和制冷系统的影响

发布时间:2018/7/2 11:01:55 浏览次数: 913

1、全封闭往复活塞压缩机壳体的温度场可分为两部分:受吸入蒸汽的影响,温度较低,处于微热或略冷的范围内。估计在30左右,并且在吸入管周围的局部套管的表面可能被暴露。由发动机内的电机产生的热量和由冷冻油产生的摩擦热主要由蒸汽进行蒸汽。安徽运动场地

2、低温环境的影响和原因是:底盘表面温度低于正常范围,原因是吸气温度太低(低于15摄氏度)。有利于冷却油和电机绕组冷却,但冷却能力下降。当吸气温度很低时,会导致壳的一半以上结露。这对液体的打击是危险的。这对压缩机是致命的打击,所以我们要特别注意。同时,大量的制冷剂溶解在冷冻机油中,不利于运动部件的润滑。安徽资质转让

3,底盘温度过高的影响和原因是:底盘表面温度超过正常范围,主要是由于制冷系统吸气温度高(15摄氏度以上)。过高的热蒸汽进入压缩机并吸收壳体内的热量,因此蒸汽的温度较高,从而壳的温度升高。过热蒸汽的温度上升很高,外壳的温度也很高。这对油的冷却是不利的。这将影响运动部件的润滑,加速磨损。这也会导致排气温度升高。

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.
