厂家揭示列管式冷凝器串联VS并联方法好坏

2019-01-10 12:47:56 无锡科达脚手架厂 阅读

列管式冷凝器是十分常用的一种冷却设备,其中还包括了多种常规类型,比如GLC型浮动列管式油冷凝器、LC列管式冷凝器、GL列管式冷凝器。这些列管式冷凝器都有共同的特点,那就是结构新颖、体积小、重量轻及换热效果显著。列管式冷凝器可以并联还可以串联使用,下面小编就给大家分析一下,列管式冷凝器是串联好还是并联好。

Tube condenser is a very common cooling equipment, which also includes a variety of conventional types, such as GLC floating tubular oil condenser, LC tubular condenser, GL tubular condenser. These tubular condensers have the same characteristics: novel structure, small volume, light weight and remarkable heat transfer effect. The tubular condenser can be used in parallel or in series. The following section will give you an analysis of whether the tubular condenser is in series or in parallel.

列管式冷凝器中的换热器材质是低肋翅片紫铜管,并采用横向折流板,纵向紊流板结构及机械胀管等先进制造工艺,因而才会有上述一系列普通冷却塔无法比拟的优点。在实际使用过程中,要冷却相同流量和初始温度液压油,采用规格相同的两台列管式冷凝器,并且还要有各自独立的水路,通相同流量和进口温度的冷却水。这两台列管式冷凝器既可以并联使用,也可以串联使用。

The heat exchanger in tubular condenser is made of copper tubes with low fins, and advanced manufacturing technologies such as transverse baffle, longitudinal turbulent plate structure and mechanical tube expansion are adopted. Therefore, the above series of advantages can not be compared with ordinary cooling towers. In the actual use process, the same flow rate and initial temperature hydraulic oil should be cooled, two tube-type condensers with the same specifications should be used, and there should be separate waterways to pass the same flow rate and inlet temperature of the cooling water. These two tubular condensers can be used in parallel or in series.

如果要是使出油口得到更低温的油流,串联连接方式比并联连接方式效果好。因为当列管式冷凝器串连接时,油的流程速度加快使换热系数将加大,换热量变大;而且油的流程变长,相当于换热面积也增大,所以换热量也会增强。

If the oil outlet is cooler, the series connection is better than the parallel connection. Because when the tubular condenser is connected in series, the heat transfer coefficient will increase and the heat transfer capacity will increase with the acceleration of the oil flow rate, and the oil flow will become longer, which corresponds to the increase of the heat transfer area, so the heat transfer capacity will also increase.

但要注意的是,当列管式冷凝器串联运行时,必须确保前面一台冷凝器的换热效率要高于后一台的换热效率。当然这种方式也会存在一些缺点,比如说油的速度加快、流程变长,流程的阻力损失会变大,油泵消耗的功率也要变大。

However, it should be noted that when the tube-and-tube condensers are running in series, it is necessary to ensure that the heat transfer efficiency of the former condenser is higher than that of the latter. Of course, this method also has some shortcomings, such as faster oil speed, longer process, greater resistance loss of the process, and greater power consumption of the oil pump.

采用串联的连接模式,不能将两台列管式冷凝器交替检修,一旦其中一台设备出现问题而导致系统停运的话,整个系统的可靠性就会随之降低不少。所以不论是串联使用还是并联使用都各有各的优点,这需要我们结合实际情况来进行衡量。

With series connection mode, two tubular condensers can not be overhauled alternately. Once one of the equipments fails and the system is shut down, the reliability of the whole system will be greatly reduced. Therefore, whether in series or in parallel, each has its own advantages, which requires us to measure the actual situation.
