齒輪泵-不銹鋼齒輪泵-KAYSEN泵業(yè)

GERMANY KAYSEN PUMP CO .,LTD

齒輪泵是機器潤滑、供油或其它液體系統(tǒng)中的一個部件，液壓泵的一種。屬旋轉式。齒輪箱內有2個或2個以上的齒輪嚙合，在旋轉作用下從一側吸入流體再向另一側排出。其振動及噪聲比螺桿泵稍大，可作為螺桿泵代用型式。其作用是使油或其它流體介質具一定的壓力和流量及流向。

齒輪泵也叫正排量裝置，正排量泵，即像一個缸筒內的活塞，當一個齒進入另一個齒的流體空間時，液體就被機械性地擠排出來。因為液體是不可壓縮的，所以液體和齒就不能在同一時間占據(jù)同一空間，這樣，液體就被排除了。由于齒的不斷嚙合，這一現(xiàn)象就連續(xù)在發(fā)生，因而也就在泵的出口提供了一個連續(xù)排除量，每轉一轉，排出的量是一樣的。隨著驅動軸的不間斷地旋轉，也就不間斷地排出流體。齒輪泵的流量直接與轉速有關。齒輪泵是依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動來輸送液體或使之增壓的回轉泵。由兩個齒輪、泵體與前后蓋組成兩個封閉空間，當齒輪轉動時，齒輪脫開側的空間的體積從小變大，形成真空，將液體吸入，齒輪嚙合側的空間的體積從大變小，而將液體擠入管路中去。吸入腔與排出腔是靠兩個齒輪的嚙合線來隔開的。齒輪泵的排出口的壓力完全取決于泵出口處阻力的大小。

主要優(yōu)點：
結構簡單緊湊、體積小、質量輕、工藝性好、價格便宜、自吸力強、對油液污染不敏感、轉速范圍大、能耐沖擊性負載，維護方便、工作可靠。

主要特點：

齒輪泵最基本形式就是兩個尺寸相同的齒輪在一個緊密配合的殼體內相互嚙合旋轉，這個殼體的內部類似“8”字形，兩個齒輪裝在里面，齒輪的外徑及兩側與殼體緊密配合。來自于擠出機的物料在吸入口進入兩個齒輪中間，并充滿這一空間，隨著齒的旋轉沿殼體運動，*在兩齒嚙合時排出。

對于粘度或密度在工藝中有變化的流體，這種泵不會受到太多影響。如果有一個阻尼器，比如在排出口側放一個濾網(wǎng)或一個限制器，泵則會推動流體通過它們。如果這個阻尼器在工作中變化，亦即如果濾網(wǎng)變臟、堵塞了，或限制器的背壓升高了，則泵仍將保持恒定的流量，直至達到裝置中最弱的部件的機械極限(通常裝有一個扭矩限制器)。

對于一臺泵的轉速，實際上是有限制的，這主要取決于工藝流體，如果傳送的是油類，泵則能以很高的速度轉動，但當流體是一種高粘度的聚合物熔體時，這種限制就會大幅度降低。

The utility model has the advantages of simple and compact structure, small volume, light weight, good processability, low price, strong self-suction, insensitivity to oil pollution, large speed range, impact resistance load, convenient maintenance and reliable work.

main feature:

The most basic form of a gear pump is that two identically sized gears mesh with each other in a tightly fitting housing. The interior of the housing resembles an "8" shape with two gears mounted inside, the outer diameter of the gear and the sides and the shell. The body is closely matched. The material from the extruder enters the middle of the two gears at the suction port and fills this space, moves along the housing as the teeth rotate, and finally exits when the two teeth mesh.

A gear pump is also called a positive displacement device. A positive displacement pump, like a piston in a cylinder, is mechanically squeezed out when one tooth enters the fluid space of the other tooth. Because the liquid is incompressible, the liquid and the teeth cannot occupy the same space at the same time, so that the liquid is eliminated. This phenomenon occurs continuously due to the continuous engagement of the teeth, thus providing a continuous exclusion at the pump outlet, which is the same amount per revolution. As the drive shaft rotates uninterrupted, the fluid is discharged without interruption. The flow of the gear pump is directly related to the speed.

For fluids with varying viscosities or densities in the process, such pumps are not affected too much. If there is a damper, such as a strainer or a limiter on the side of the discharge port, the pump will push the fluid through them. If the damper changes during operation, ie if the screen becomes dirty, clogged, or the back pressure of the limiter rises, the pump will maintain a constant flow until it reaches the mechanical limit of the weakest part of the device. (usually equipped with a torque limiter).

There is actually a limit to the speed of a pump, which depends mainly on the process fluid. If the oil is delivered, the pump can rotate at a very high speed, but when the fluid is a high viscosity polymer melts This limitation is greatly reduced when the body is in the body.
