要想知道板式换热器需要经常清理保养吗？我们就先要了解板式换热器是什么，板式换热器是一种换热设备，它是由一组波纹金属（不锈钢、钛材、哈式合金等更高材质）板组成，板片间有空隙，便于介质经过，它特定的结构使同一板片左右两侧的冷热介质经过板片(一般是不锈钢材质)而不会混合，在这里冷热介质是两个独立而密封的结构与换热方式。
Do you want to know if plate heat exchangers need regular cleaning and maintenance? We first need to understand what a plate heat exchanger is. A plate heat exchanger is a type of heat exchange equipment composed of a set of corrugated metal plates (made of higher materials such as stainless steel, titanium, and Hastelloy) with gaps between the plates for the medium to pass through. Its specific structure allows the cold and hot media on both sides of the same plate to pass through the plates (usually made of stainless steel) without mixing. Here, the cold and hot media are two independent and sealed structures and heat exchange methods.
板式换热器需要经常清理保养吗？
Do plate heat exchangers need regular cleaning and maintenance?
所以我们才能进一步知道，它是需要经常清理保养的。
So we can further understand that it requires regular cleaning and maintenance.
保养的方法也是有很多种，我们也给大家说明一下。
There are also many methods of maintenance, and we will explain them to everyone.
1、清除杂质：因为换热器杂质的排出主要靠的是润滑油的循环工作来实现的，之后再经过滤清器滤掉。
1. Removing impurities: Because the discharge of impurities from the heat exchanger mainly relies on the circulation of lubricating oil, which is then filtered out through a filter.
2、防腐蚀生锈：防止因液体、水蒸汽、腐蚀性液体、氧化物等引起的锈蚀。
2. Corrosion and rusting prevention: prevent rusting caused by liquids, water vapor, corrosive liquids, oxides, etc.
3、降低摩擦力：在换热器磨擦面加入润滑油，能使摩擦系数降低，从而减少了磨擦阻力，节约了能源消耗。
3. Reduce friction: Adding lubricating oil to the friction surface of the heat exchanger can lower the friction coefficient, thereby reducing frictional resistance and saving energy consumption.
4、减少磨损：换热器加入润滑油可以减少磨粒磨损、表面疲劳、粘着磨损等所造成的摩损。
4. Reduce wear: Adding lubricating oil to the heat exchanger can reduce wear caused by abrasive wear, surface fatigue, adhesive wear, etc.
5、传递动力：在多数情况下为换热器加入润滑油具有传递动力的功能。
5. Transmission of power: In most cases, adding lubricating oil to the heat exchanger has the function of transmitting power.
定期适当的为换热器添加润滑油可以在一定程度上减少换热器故障的出现，可以提高换热器的换热效率。
Regularly and appropriately adding lubricating oil to the heat exchanger can reduce the occurrence of heat exchanger failures to a certain extent and improve the heat transfer efficiency of the heat exchanger.
