软化水设备慢冲洗(置换)：在用盐水流过树脂以后，用原水以同样的流速慢慢将树脂中的盐全部冲洗干净的过程叫慢冲洗，由于这个冲洗过程中仍有大量的功能基团上的钙镁离子被钠离子交换，根据实际经验，这个过程中是再生的主要过程，所以很多人将这个过程称作置换。这个过程一般与吸盐的时间相同，即30分钟左右。
Slow flushing (replacement) of softened water equipment: after flowing salt water through the resin, the process of slowly flushing all the salt in the resin with raw water at the same flow rate is called slow flushing. Because there are still a large number of calcium and magnesium ions on the functional group are exchanged by sodium ions in the flushing process, according to practical experience, this process is the main process of regeneration, so many people will take this process It's called displacement. This process is generally the same as the time of salt absorption, i.e. about 30 minutes.
快冲洗：为了将残留的盐彻底冲洗干净，要采用与实际工作接近的流速，用原水对树脂进行冲洗，这个过程的最后出水应为达标的软水。一般情况下，快冲洗过程为5-15分钟。
Fast flushing: in order to thoroughly flush the residual salt, the resin shall be flushed with raw water at a flow rate close to the actual work, and the final effluent of this process shall be soft water up to the standard. Generally, the fast flushing process is 5-15 minutes.
