水动力比例加药器
1-水比例加药器的工作原理：
加药器是以流动的压力水为动力，水压流失小，且不需要其他任何动力设施，用加药器内的水动力为引擎，带动加药器内的活塞和连杆，将液体添加剂直接吸入并且溶于水流之中。这个装置在一个圆柱体内上下运动，将水压出去的同时，此装置将装在底部容器里的添加剂通过导管均匀的吸入到水流中。上下运动反复进行，从而达到将添加剂均匀连续不断的添加到流动水中的效果。
2-加药器的安装和固定：
1-选择地点：加药器的进水口和出水口一定要与主管道的进水口和出水口相一致。
2-加药器必须按照：加药器在上，液体吸入导管在下的方法安装
3-将加药器固定到墙上或者固定到其他的设施上。
4-将加药器的进水口和出水口按照水流方向安装，保证其密闭性。（如图）
5-在水阀和加药器的入口之间安装100-120目的过滤网。
6-当需要加药的时候关闭加药器侧支阀门，打开加药器两侧阀门即可加药。
7-当加药器开始工作的时候，会听到咔嚓声，这时按下加药器顶部的放气阀，当有少量水流出的时候松开即可保证加药器的正常工作。
4-加药器的主要应用领域：
1-园艺行业：花卉、果蔬等施肥、储存、病虫害控制
2-畜牧行业：鸡/鸭/牛/猪等畜禽保健的定比加药
3-工业领域：水处理、 化工、金属加工、消防等行业
4-除味/冷却/润滑/等特殊溶剂的定比稀释；广泛用于啤酒、饮料行业的链条润滑剂添加设备、消毒剂添加设备和啤酒瓶、啤酒发酵罐的清洗设备上
5-其他行业：洗车/印刷/医院/酒业等
5-加药器调整使用的比例：
加药器可以根据实际的情况来调整注入水流中的添加剂比例，从而使添加剂的效果达到，具体方法如下：
1-松开螺丝，从加药器的上部拿下U型调节锁。
2-按照加药器上的水刻度的比例来预设液态添加剂和水的比例：
逆时针方向调整是增加液体添加剂的比重。
顺时针方向调整是减少液体添加剂的比重。
在加药器上的百分数是按照加药器最后出水量为100来计的。
3-请转动调节器，直到U型调节所以上的孔插入加药器的槽口。
4-使劲将U型调节锁按入加药器上槽口中，直到相互扣紧。
6-注意事项：
1-在使用自动加药器的时候确保盛放液体添加剂的容器不是空的！
2-放气阀：在启动加药器的最初，应该往下按住放气阀几秒钟，排出内部已有的空气，这个过程会有少许水流出，在排出空气后，迅速关上放气阀。
3-安装及使用过程中确保加药器进水端必须安装过滤设备。
旁接于主管道，水力驱动不需要额外动力，不会造成主管道上的压力损失。

Instruction Manual of Jiayitong Automatic Proportional Pump (Doser)
1-Working Principle:
The proportional pump takes the flowing pressure water as power, having small water pressure loss, without any other power facilities. It uses water power of the proportional pump as engine which drives the piston and the connecting rod inside the proportional pump, sucks up the liquid additive directly and makes it dissolve in the water flow. This device moves up and down in a cylinder. When pressing out the water, it uniformly sucks the additives loaded at the bottom of the container into the water flow through a tube. Repeat the up-and-down motion until the effect is achieved that the additive is added to the flowing water evenly and constantly.
2-Specification:
Model: 2504
Proportional range: 0.4%-4%
Flow-rate range: 20-2500 L/H
Flow temperature: 4℃-30℃
Working water pressure: 0.2-6kg
Caliber of water inlet and water outlet: 32mm/25mm
3- Installation and fixation:(Standard installation and bypass installation are shown in the figure)
1- Choose the location: the water inlet and water outlet of the proportional pump must be in accordance with those of the main pipe.
2- Proportional pump must be installed according to the method that the proportional pump is above the fluid intake tube.
3- Fix the proportional pump to a wall or other facilities.
4. Install the water inlet and outlet of the proportional pump according to the direction of water flow, so as to ensure its leakproofness. (As shown in figure)
5. Install 100-120 mesh screen between the inlets of water valve and proportional pump.
6-When the addition of drugs is required, close the side branch valves of the proportional pump. The addition of drugs can be carried out when the valves on both sides of the proportional pump are opened.
7-Crack sound will be heard when proportional pump begins to work. At this time, push the air vent valve on the top of the proportional pump and release the valve when small amount of water flows out. In this way, normal operation of doser can be ensured.
4- Main Application Fields:
1-Horticulture industry: the fertilization, storage and pest control for flowers, fruits and vegetables, etc. 2-Animal husbandry: the fixed-ratio health dosing for livestock and poultry, such as chickens, ducks, oxen and pigs. 3-Industrial field: water treatment, chemical engineering, metal processing, and fire control, etc. 4-Constant proportion dilution of special solvents such as smell removal solvent, cooling solvent and lubricating solvent; 5-Car-washing industry, printing industry, hospitals, wine industry and other industries.
5-Adjust the using proportion:
The proportional pump can adjust the additive proportion in water according to actual situations, so as to achieve the best effect of additive. Specific ways are as follows:
1-Loosen the screw, and take off the U-style adjusting lock from the upper part of the proportional pump.
2-Predetermine the proportion of liquid additive and water according to the proportion of the water scale on the proportional pump:
A counterclockwise adjustment is to increase the proportion of liquid additive.
A clockwise adjustment is to decrease the proportion of liquid additive.
The percentage on the proportional pump is calculated on the basis that the final water yield of the proportional pump is 100.
3-Please turn the regulator until the hole above the U-style adjusting lock is inserted into the notch of the proportional pump.
4-Press the U-model adjusting lock hard into the upper notch of the proportional pump until each other is locked tightly.
6-Notice:
1-Make sure that the container holding the liquid additive is not empty during the use of the automatic proportional pump!
2-Air release valve: It is necessary to press down the air release valve for several seconds to vent the air already existing inside when initially starting the proportional pump. During this process, there may be a little water flowing out. Close the valve quickly after the air is expelled from it.
3-Make sure the filter plant is installed at the inlet of the proportional pump while installing and using.
4-If the working resistance grows bigger while using, then lubricating oil should be added at the piston to increase the service life.
5-The proportional pump should be washed with clean water after using to reduce corrosion and extend the service life of the proportional pump.
