还采用了一些新型滴水器,以减少堵塞问题。其中一种就是在开机和关机时,如果水压低于工作压,滴水器也可把水冲出来。不过,在冲洗状态,要加大流量,这样就需要加大管径和泵的功率,结果该系统的费用也会增加。还有一些新型滴水器容易拆卸,这样如果滴水器堵塞可以疏通开,而不需要更换滴水器。还有的滴水器装有节流装置,可以补偿压力 Some new drips have also been used to reduce the problem of blockage. One of them is that when the water pressure is lower than the working pressure at the time of starting up and shutting down, the water dripping device can flush the water out. However, in the flush state, to increase the flow, so you need to increase the diameter and pump power, the result of the system costs will increase. Some new drip guards are easy to disassemble, so that if the drippers are clogged, they can be opened without the need to change drippers. Some drippers are equipped with throttling devices to compensate for the pressure
