德國KAYSEN凱森進(jìn)口齒輪泵概述:
齒輪泵是機(jī)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(zhuǎn)式。齒輪箱內(nèi)有2個或2個以上的齒輪嚙合,在旋轉(zhuǎn)作用下從一側(cè)吸入流體再向另一側(cè)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(zhì)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(nèi)的活塞,當(dāng)一個齒進(jìn)入另一個齒的流體空間時,液體就被機(jī)械性地擠排出來。因?yàn)橐后w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(zhuǎn)一轉(zhuǎn),排出的量是一樣的。隨著驅(qū)動軸的不間斷地旋轉(zhuǎn),也就不間斷地排出流體。齒輪泵的流量直接與轉(zhuǎn)速有關(guān)。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(zhuǎn)泵。由兩個齒輪、泵體與前后蓋組成兩個封閉空間,當(dāng)齒輪轉(zhuǎn)動時,齒輪脫開側(cè)的空間的體積從小變大,形成真空,將液體吸入,齒輪嚙合側(cè)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*取決于泵出口處阻力的大小。
主要優(yōu)點(diǎn):
結(jié)構(gòu)簡單緊湊、體積小、質(zhì)量輕、工藝性好、價格便宜、自吸力強(qiáng)、對油液污染不敏感、轉(zhuǎn)速范圍大、能耐沖擊性負(fù)載,維護(hù)方便、工作可靠。
主要特點(diǎn):
齒輪泵zui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(nèi)相互嚙合旋轉(zhuǎn),這個殼體的內(nèi)部類似“8”字形,兩個齒輪裝在里面,齒輪的外徑及兩側(cè)與殼體緊密配合。來自于擠出機(jī)的物料在吸入口進(jìn)入兩個齒輪中間,并充滿這一空間,隨著齒的旋轉(zhuǎn)沿殼體運(yùn)動,zui后在兩齒嚙合時排出。
齒輪泵也叫正排量裝置,正排量泵,即像一個缸筒內(nèi)的活塞,當(dāng)一個齒進(jìn)入另一個齒的流體空間時,液體就被機(jī)械性地擠排出來。因?yàn)橐后w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(zhuǎn)一轉(zhuǎn),排出的量是一樣的。隨著驅(qū)動軸的不間斷地旋轉(zhuǎn),也就不間斷地排出流體。齒輪泵的流量直接與轉(zhuǎn)速有關(guān)。
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(cè)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(dá)到裝置中zui弱的部件的機(jī)械極限(通常裝有一個扭矩限制器)。
對于一臺泵的轉(zhuǎn)速,實(shí)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(zhuǎn)動,但當(dāng)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。

Germany KAYSEN imported gear pump Overview:
Gear pumps are one of the components of a machine lubrication, oil supply or other liquid system, a hydraulic pump. Is a rotary type. There are two or more gear meshes in the gearbox, and the fluid is sucked from one side to the other side under rotation. Its vibration and noise slightly larger than the screw pump, screw pump can be used as a substitute type. Its role is to make oil or other fluid medium with a certain pressure and flow and flow.
The gear pump is also called the positive displacement device, the positive displacement pump, which is like a piston in a cylinder, and when a tooth enters the fluid space of the other tooth, the liquid is mechanically squeezed out. Because the liquid is incompressible, so the liquid and teeth can not occupy the same space at the same time, so that the liquid is excluded. As the teeth continue to engage, this phenomenon occurs continuously, and thus also provides a continuous reduction in the pump outlet, each turn a turn, the amount of discharge is the same. As the drive shaft rotates uninterrupted, the fluid is discharged without interruption. The flow of the gear pump is directly related to the speed. The gear pump is a rotary pump that relies on the change in the working volume between the pump cylinder and the meshing gear and the movement to deliver the liquid or to pressurize it. The two gears, the pump body and the front and rear cover to form two enclosed spaces. When the gear rotates, the volume of the space on the gear off side becomes small and forms a vacuum to suck the liquid, and the volume of the space on the gear meshing side changes from large to large Small, and the liquid into the pipe to go. The suction chamber and the discharge chamber are separated by the meshing lines of the two gears. The pressure at the exit of the gear pump depends entirely on the resistance at the pump outlet.
Key Benefits:
Simple and compact structure, small size, light weight, good technology, cheap, self-absorption strong, not sensitive to oil pollution, speed range, impact resistance load, easy maintenance, reliable work.
main feature:
The most basic form of the gear pump is that the two gears of the same size are engaged with each other in a tightly fitted housing, the interior of which is similar to the "8" shape, the two gears are mounted inside, the outer diameter of the gears and the sides Close fit. The material from the extruder enters the middle of the two gears at the suction port and fills the space, moving along the housing as the teeth rotate, and finally discharging when the teeth are engaged.
The gear pump is also called the positive displacement device, the positive displacement pump, which is like a piston in a cylinder, and when a tooth enters the fluid space of the other tooth, the liquid is mechanically squeezed out. Because the liquid is incompressible, so the liquid and teeth can not occupy the same space at the same time, so that the liquid is excluded. As the teeth continue to engage, this phenomenon occurs continuously, and thus also provides a continuous reduction in the pump outlet, each turn a turn, the amount of discharge is the same. 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 pumps with varying viscosities or densities in the process, this pump will not be affected too much. If there is a damper, such as a filter or a limiter on the discharge side, the pump will push the fluid through them. If the damper changes during operation, that is, if the screen becomes dirty, clogged, or the back pressure of the limiter rises, the pump will maintain a constant flow until the mechanical limit of the weakest part in the device is reached (Usually fitted with a torque limiter).
The speed of a pump is actually limited, depending on the process fluid. If the oil is delivered, the pump can rotate at a high speed, but when the fluid is a high viscosity polymer melt Body, this restriction will be greatly reduced.
