厂家对列管式冷凝器的使用方法解读

很多人都有这样的疑问,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(水路各自独立,通相同流量和进口温度的冷却水)油路串联联接方式和油路并联连接方式,哪种效果好,使出油口得到更低温的油流?要想解决这个问题,就需要用到列管冷凝器,下面小编给大家介绍一下吧。

Many people have such doubts, to cool the same flow rate and initial temperature hydraulic oil, using the same specifications of two tubular condensers (water lines are independent, through the same flow rate and import temperature of cooling water), oil pipeline series connection mode and oil pipeline parallel connection mode, which effect is better, so that the oil outlet has a lower temperature of oil flow? In order to solve this problem, we need to use tube condenser. Let's introduce it to you.

一、用法

I. Usage

1、油系统冷凝器串连接时,油的流程速度加快使换热系数将加大,换热量变大;

1. When the oil system 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.

2、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。串联运行时,前面一台冷凝器的换热效率要高于后一台的换热效率。

2. The longer the oil flow, the larger the heat transfer area, so the heat transfer capacity will be enhanced. When running in series, the heat transfer efficiency of the former condenser is higher than that of the latter.

二、串联连接的缺点是:

2. The disadvantages of series connection are:

1、串联连接时,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;

1. When connected in series, the speed of oil increases, the flow becomes longer, the resistance loss of the flow becomes larger, and the power consumption of the oil pump also increases.

2、并联连接,两台冷凝器可以交替检修,而串联不能。其中一台冷凝器出现问题系统就得停运,所以串联连接时系统的可靠性降低。

2. Parallel connection, two condensers can be alternately repaired, but not in series. One of the condensers has problems and the system has to be shut down, so the reliability of the system is reduced when connected in series.

所以,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(水路各自独立,通相同流量和进口温度的冷却水),要是使出油口得到更低温的油流,油路串联连接方式比油路并联连接方式效果好。

Therefore, in order to cool the hydraulic oil with the same flow rate and initial temperature, two tubular condensers with the same specifications (water lines are independent, and cooling water with the same flow rate and inlet temperature) are used. If the oil flow at the outlet is cooler, the series connection of oil lines is better than the parallel connection of oil lines.
