1. 加藥泵的結構：該泵的由電機、傳動箱、缸體等三部份組成。加藥泵傳動箱部件是由弓型連桿凸輪機構、行程調節(jié)機構和速比蝸輪機構組成；通過旋轉調節(jié)手輪來實行高調節(jié)行程，從面改變弓型連桿中前后距離來達到改變柱塞行程的目的。 缸體部件是由泵頭、吸入閥組、排出閥組、柱塞和填料密封件組成。
2. 加藥泵工作原理：電機經(jīng)聯(lián)軸器帶動蝸桿并通過蝸輪減速使主軸和偏心輪作回轉運動，由偏心輪帶動弓型連桿的滑動調節(jié)座內作往復運動。當柱塞向后死點移時，泵腔內逐漸形成真空，吸入閥打開，吸入液體；當柱塞向前死點移動時，此時吸入閥關閉，排出閥打開，液體在柱塞向進一步運動時排出。在加藥泵的往復順還工作形成連續(xù)有壓力、定量的排放液體(圖\文www.ds128.cn/)。
中譯英：
1 of the dosing pump structure : the pump consists of a motor, gear box, cylinder and other three parts. Dosing pump gear box parts by arch type cam and connecting rod mechanism, a travel adjusting mechanism and the ratio of worm gear mechanism; through the rotation of the adjusting hand wheel to execute high stroke adjustment, from the surface to change the bow rod front distance to achieve the purpose of changing the plunger stroke. Parts of the cylinder is composed of a pump head, suction valve, discharge valve group group, the plunger and the packing seal components.
2 dosing pump working principle: motor drive the worm and the worm gear coupling shaft and the eccentric rotation of rotary movement, composed of an eccentric wheel arch type connecting rod slide adjustment block for reciprocating motion. When the plunger moves backward dead point, the pump cavity is formed gradually vacuum, suction valve is opened, the inhalation of the liquid; when the plunger moves forward dead, when the suction valve is closed, the discharge valve is opened, the liquid in the piston to further movement of discharge. The dosing pump reciprocating along the working pressure, forming a continuous quantitative discharging liquid.
