detailed information

Drip arrows are often used for potted crops, and also for crops with frequent or uneven planting spacing (such as flowers). The pipeline layout is consistent with other irrigation systems, and the planting quantity and direction of crops need to be considered, so as to reasonably arrange the direction of main and branch pipes.

The common dropping arrow system is mainly composed of water source, head hub (often equipped with water pump, check valve, gate valve, pressure gauge, flow meter, etc.), transmission and distribution water pipe network and end emitter dropping arrow, etc.

Drip arrow belongs to a precision irrigation technology, which has high requirements on the water quality of the water source. It is generally necessary to install filters of suitable models when in use. The common ones are mainly centrifugal filters and mesh filters. If relatively clean groundwater is used, a filter with a small mesh number can be installed or no filter can be installed. For irrigation with river water, reservoir water or storage pool water, filters must be installed. At the same time, the combination of centrifugal filter and online filter is better.

Combination and connection of dropping arrows: the common combination methods of dropping arrows are single arrow, one out two or one out four dropping arrows. Users can also choose long arrow, short arrow, straight arrow and curved arrow according to actual needs. A small tee or a small five-way is used as a connector in use Φ 3 capillary connection. In general, we use the dropping arrow in combination with the pressure compensated dripper to ensure double guarantee, so that the water from the dropping arrow is more stable and uniform. In this way, Φ 3. The capillary is connected with the pressure compensated emitter, and then Φ 3 punch holes on the capillary (commonly used) Φ 20 or Φ 16pe pipe), connect the pressure compensated emitter with the capillary orifice. Finally, insert the dropping arrow into the soil and fix it. After the annual irrigation, collect the dropping arrows, clean them and keep them properly for use when the next irrigation season comes.

滴箭常用于盆栽作物使用,也适用于作物种植间距经常改变或不均匀的作物(如花卉)。管道布置和其他灌溉系统一致,需要考虑作物种植数量、走向,从而合理的布置干、支管走向。

常见的滴箭系统主要有水源、首部枢纽(常配有水泵、逆止阀、闸阀、压力表、流量表等)、输配水管网及末端灌水器滴箭等几部分组成。
滴箭属于一种精度灌溉技术,对水源水质要求较高,使用时一般需要安装适应型号的过滤器,常见的主要有离心过滤器、网式过滤器。如采用较为洁净的地下水,可以安装目数较小的过滤器或不安装过滤器。对于采用河水、水库水或蓄水池水进行灌溉时,必须安装过滤器。同时采用离心式过滤器及网上过滤器组合效果更佳。
滴箭的组合连接:滴箭常用的组合方式有单箭、一出二式或一出四式滴箭。用户也可以根据实际需求选择长箭、短箭、直箭及弯箭。使用中采用小三通或小五通作为连接件,与Φ3毛管连接。通常使用时,我们采用滴箭与压力补偿式滴头配合使用,双重保障,这样滴箭出水更加稳定、均匀。采用此种方式时,Φ3毛管与压力补偿式滴头连接,然后采用Φ3打孔器在毛管上打孔(常用Φ20或Φ16PE管),将压力补偿式滴头与毛管孔口连接。最后,将滴箭箭头插入土中固定即可。待每年灌溉结束后,将滴箭收好,清洗干净后妥善保存,待下次灌溉季节来临时使用。
