1、齒輪泵
1. Gear pump
適用于無填充物、腐蝕性、粘度小于20000厘泊的膠水
It is suitable for non filling, corrosive glue with viscosity less than 20000 centipoise
兩個相同尺寸的齒輪相互嚙合，并在緊密匹配的外殼中旋轉。房屋的內部類似于“8”形狀。內部安裝了兩個齒輪。齒輪的外徑和兩側與外殼緊密匹配。物料從儲料筒進入吸入口兩個齒輪的中間，填滿這個空間。隨著齒的轉動，沿殼體運動，兩齒嚙合后排出。
Two gears of the same size mesh with each other and rotate in a closely matched housing. The interior of the house is similar to the "8" shape. Two gears are mounted internally. The outer diameter and both sides of the gear are closely matched with the housing. The material enters the middle of the two gears at the suction inlet from the storage barrel to fill the space. With the rotation of the teeth, it moves along the shell, and the two teeth are discharged after meshing.
2、螺桿泵
2. Screw pump
適用于有沉淀(含部分填料)、腐蝕性低、粘度在30000cps以下的膠水
It is suitable for the glue with precipitation (including some fillers), low corrosion and viscosity below 30000 CPS

螺桿泵按回轉嚙合容積式原理工作。螺桿泵的主要工作部件是偏心螺桿(轉子)和固定襯套(定子)。由于這兩部分的特殊幾何形狀，形成了單獨的密封腔。介質沿軸向均勻流動。內部流量低，體積保持不變。螺桿泵壓力穩定，所以不會有漩渦和攪動。
The screw pump works according to the principle of rotary meshing volumetric type. The main working parts of screw pump are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometry of the two parts, a separate sealing cavity is formed. The medium flows uniformly along the axial direction. The internal flow rate is low and the volume remains unchanged. Screw pump pressure is stable, so there will be no vortex and agitation.
對介質適應性強，流量穩定，壓力波動小，自吸能力強，是其他明顯泵所不能替代的。而且，在后期維護方面，螺桿泵只需更換定子(螺桿護套)，大大降低了成本。
It has strong adaptability to medium, stable flow, small pressure fluctuation and strong self-priming capacity, which can not be replaced by any other pump. Moreover, in terms of later maintenance, the screw pump only needs to replace the stator (screw sheath), which greatly reduces the cost.
3、所謂柱塞泵
3. The so-called plunger pump
所謂的柱塞泵由電動機、泵頭、滾珠絲杠、傳動齒輪、感應開關和底板組成。電動機與傳動齒輪相連。所述兩個滾珠絲杠的一側固定在泵頭固定板上，另一側連接傳動齒輪。安排在每個滾珠螺桿柱塞桿時,柱塞是安排前固定板之間的滾珠絲桿和泵頭固定板提供的泵頭四個小孔膠水,與外界連接的一端,而另一端密封柱塞桿。
The so-called plunger pump is composed of motor, pump head, ball screw, transmission gear, inductive switch and base plate. The motor is connected to the transmission gear. One side of the two ball screws is fixed on the pump head fixing plate, and the other side is connected with the transmission gear. When arranging each ball screw plunger rod, the plunger is arranged with the ball screw between the front fixing plate and the four small holes of the pump head provided by the pump head fixing plate. One end is connected with the outside, and the other end is sealed with the plunger rod.
感應開關的感官信號后,它改變電機旋轉的方向和方向上的換向閥泵頭改變膠的方向,這樣兩個膠進出港口總是在一個膠和膠。主、輔泵換向時，泵出膠量少，出膠量不穩定。建議灌裝精度高、灌裝比例高的客戶謹慎使用。后期的雙組份打膠機維護費用比前兩臺泵高出許多倍。
After sensing the sensory signal of the switch, it changes the direction of rotation of the motor and the direction of the reversing valve. The pump head changes the direction of the glue, so that the two glue in and out ports are always in one glue and glue. When the main pump and the auxiliary pump change direction, the output of the pump is small and unstable. It is suggested that customers with high filling accuracy and high filling proportion should use it carefully. The maintenance cost of the later two-component gluing machine is many times higher than that of the first two pumps.
