1. 加藥泵的結構：該泵的(de)由電機(jī)、傳(chuán)動箱、缸(gāng)體等三(sān)部份組成。 加藥泵 傳動箱部(bù)件是由弓型連杆凸輪機(jī)構、行程調節機構和(hé)速比蝸輪機構組成；通過旋轉調(diào)節手輪來實行(háng)高調節行程，從面改變(biàn)弓型連杆中前(qián)後距離來達到改變柱塞行程的目(mù)的。 缸體部(bù)件是由(yóu)泵頭、吸入閥組、排(pái)出閥組、柱塞和填料密封件組成。
2. 加(jiā)藥泵工作(zuò)原理：電機經聯軸器帶動蝸杆并通過蝸輪減速使(shǐ)主軸和偏(piān)心輪作回轉(zhuǎn)運動，由偏心輪帶動弓型連杆的滑動調(diào)節座内作往(wǎng)複運動。當柱塞(sāi)向後死點移時，泵腔内(nèi)逐漸形成真空，吸入閥打開(kāi)，吸入液體；當柱塞向(xiàng)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 的往複順(shùn)還工作形成連續有壓力、定量的(de)排放液體(圖\文 xiaojikuaipao.top/ )。

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.
