滴灌系统由于设计不合理、设备质量差、施工安装不细和管理不善,在运行中时常出现故障。常见的故障有:1.水源水质不清净使滴灌运行受阻我省水源工程一般是设在高处的蓄水池(天池),其开敞面大,当水位静止时间较长、气温较高时,水中容易生长青苔,从而使滴灌运行受阻。防止的办法有两种:一是在灌水间歇期较长时,将池水放空;二是在蓄水池放水口设置过滤器(过滤网面积应为出水口面积6～8倍),10～15天清洗一次过滤器。
Drip irrigation system due to unreasonable design, poor quality equipment, construction and installation is not fine and poor management, often in operation failure. Common failures are: 1. Poor water quality drip irrigation run blocked Our water project is generally located at a height of the reservoir (Tianchi), the open area is large, when the water level longer still, the temperature is high , Easy to grow moss in the water, so that drip irrigation operation blocked. There are two ways to prevent: First, the irrigation interval is longer, the pool of water to vent; Second, set the reservoir outlet filter (filter area should be outlet area of 6 to 8 times), 10 to 15 Clean the filter once a day
