如今, 越来越多的农田和种植园开始使用节水灌溉系统. 这将灌溉效率提高到了新的水平. 然而, 在实际使用灌溉系统中, 可能仍会发生一些问题.
例如, 水输出可能会变得越来越小, 和管道, 滴头, 洒水器可能会堵塞. 这些问题的原因很可能与过滤器有关. 如果灌溉系统不配备过滤器, 或如果已安装的过滤器不合适或不合格, 或如果过滤器未正确维护, 堵塞问题很容易发生.
所以, 过滤器在整个灌溉系统中起着非常重要的作用. 这篇文章将为您提供四个方面的详细介绍: 灌溉过滤器的重要性, 灌溉过滤器的类型, 选择灌溉过滤器, 以及灌溉过滤器的维护.
为什么灌溉过滤器如此重要?
让我们以滴灌系统为例. 在滴灌系统中, 末端供水设备通常是滴管者. 有时您可能会注意到滴管起初正常工作, 但逐渐, 水流变慢慢, 最终, 根本没有水出来. 造成这个问题的原因很可能堵塞了!
一些灌溉系统使用不适合直接灌溉的水源. 例如, 井水, 高沙含量的河水, ETC. 这些水源包含很多小的沙粒和其他杂质. 如果将这种水直接引入未经任何治疗的灌溉系统, 即使没有堵塞管道, 它一定会堵塞滴头.
因为滴头的出口孔很小, 即使很小的颗粒和杂质也会随着时间的流逝堵塞滴头. 最终, 这将影响整个灌溉系统的运行.
为了防止这个问题, 必须在水源上安装过滤器，以过滤水中的杂质. 然后, 干净的水被输送到灌溉管中. 这样, 不再发生堵塞.
灌溉过滤器的作用非常重要. 如果我们将灌溉系统与人体进行比较, 然后过滤器就像肾脏一样 - 其功能是过滤所有 “有毒的” 杂质!
灌溉过滤器的类型
一般来说, 灌溉项目中使用的过滤系统分为两个级别: 原发性过滤和继发过滤.
主要过滤是过滤的初始阶段. If the irrigation system does not have strict requirements for water quality, then only primary filtration is sufficient. But for drip irrigation or sprinkler irrigation—these two methods require higher water quality standards, and it is necessary to avoid clogging of drippers or sprinklers—so secondary filtration with finer precision must be used, or even a combination of both primary and secondary filtration!
Primary filtration generally uses sand filters and hydrocyclone sand separators. Secondary filtration usually uses disc filters and screen filters. Below is an introduction to these four products:
灌溉砂过滤器
This type of filter has a large tank, using sand and gravel as the filtering medium. It is mainly used to filter larger impurities. If there are many floating objects in the river or pond (树叶, 藻类, ETC。), 砂过滤器可以有效拦截这些杂质并进行初步过滤.
可以单独使用砂过滤器. 如果要增强过滤效果, 也可以并行使用多个沙子过滤器.

氢气砂砂分离器
该过滤器的独特特征是它具有锥形储罐, 底部连接了一个沙子箱. 如果将地下水用作灌溉区的水源, 然后，在初级过滤阶段通常使用氢碳隆砂分离剂.
由于地下水中的浮动物体较少, 它的杂质主要是沙子, 石颗粒, ETC。, 它适合使用氢气砂砂分离器, 基于离心力的工作. The difference in density between water and sand makes it possible to separate them effectively through centrifugal force, achieving the purpose of filtration.

灌溉光盘过滤器
The disc filter is a fine filtration device. Its core filtering component is a stack of plastic circular discs with grooves.
When water enters the filter, these discs are pressed tightly together under the force of elasticity and water pressure, thereby intercepting impurities in the water and achieving the filtering effect. It’s important to note that impurities will accumulate in the discs over time, which may cause clogging and reduce filtration efficiency. 所以, 圆盘需要定期卸下和清洁，以确保圆盘过滤器可以长时间正常工作.

灌溉屏幕过滤器
这种类型的过滤器使用不锈钢网屏幕作为过滤介质. 网格有很好的开口, 因此，孔的大小决定了过滤精度. 当水流入过滤器时, 大于网格开口大的杂质被拦截, 干净的水穿过网状并进入灌溉管.
就像光盘过滤器一样, 网格中的杂质不应长时间积聚. 所以, 需要定期清洁网格，以确保过滤器正常运行.

如何选择过滤器?
在节水灌溉系统中, primary and secondary filtration are generally used together. When selecting a filter, it is necessary to determine the type and combination of filters based on the type of impurities in the water source.
If there are very few impurities in the water source, then installing just one filter is enough — you can choose a disc filter or a screen filter.
If there are more impurities in the water, with a large amount of suspended matter and quite a bit of sediment, then a combination of a sand filter and a disc filter or screen filter should be used.
If the water source is groundwater, since groundwater rarely contains floating matter, a combination of a hydrocyclone sand separator and a disc filter or screen filter is a good choice.
The above is a general method for selection. 实际上, based on the type, concentration, and particle size of the impurities, there are more refined filtering solutions. If you want to learn more, 随意 联系我们 to consult with a product expert.
Maintenance of Irrigation Filters
The most common problem with irrigation filters is reduced filtration performance (manifested as decreased water output or clogging). This is caused by impurities in the water accumulating inside the filter over long-term use without being cleaned. Over time, this will inevitably increase filtration resistance and affect the irrigation water flow.
所以, it is necessary to maintain the filter regularly, which means cleaning the filter element on a regular basis. 一般来说, there are pressure gauges at the inlet and outlet of the filter. You can determine whether the filter needs cleaning based on the pressure difference.
此外, 许多过滤器都带有后冲洗功能. 无需删除过滤器元件 - 可以使用反向水流清洁内部零件, 杂质将通过排水口出院, 这很方便.
