德国KAYSEN凯森口齿轮泵概述:

齿轮泵是机器润滑、供油或其它液体系统中的一个部件,液压泵的一种。属旋转式。齿轮箱内有2个或2个以上的齿轮啮合,在旋转作用下从一侧吸入流体再向另一侧排出。其振动及噪声比螺杆泵稍大,可作为螺杆泵代用型式。其作用是使油或其它流体介质具一定的压力和流量及流向。


齿轮泵也叫正排量装置,正排量泵,即像一个缸筒内的活塞,当一个齿进入另一个齿的流体空间时,液体就被机械性地挤排出来。因为液体是不可压缩的,所以液体和齿就不能在同一时间占据同一空间,这样,液体就被排除了。由于齿的不断啮合,这一现象就连续在发生,因而也就在泵的出口提供了一个连续排除量,每转一转,排出的量是一样的。随着驱动轴的不间断地旋转,也就不间断地排出流体。齿轮泵的流量直接与转速有关。齿轮泵是依靠泵缸与啮合齿轮间所形成的工作容积变化和移动来输送液体或使之增压的回转泵。由两个齿轮、泵体与前后盖组成两个封闭空间,当齿轮转动时,齿轮脱开侧的空间的体积从小变大,形成真空,将液体吸入,齿轮啮合侧的空间的体积从大变小,而将液体挤入管路中去。吸入腔与排出腔是靠两个齿轮的啮合线来隔开的。齿轮泵的排出口的压力*取决于泵出口处阻力的大小。


主要优点:
结构简单紧凑、体积小、质量轻、工艺性好、价格便宜、自吸力强、对油液污染不敏感、转速范围大、能耐冲击性负载,维护方便、工作可靠。


主要特点:

齿轮泵zui基本形式就是两个尺寸相同的齿轮在一个紧密配合的壳体内相互啮合旋转,这个壳体的内部类似“8”字形,两个齿轮装在里面,齿轮的外径及两侧与壳体紧密配合。来自于挤出机的物料在吸入口进入两个齿轮中间,并充满这一空间,随着齿的旋转沿壳体运动,zui后在两齿啮合时排出。

齿轮泵也叫正排量装置,正排量泵,即像一个缸筒内的活塞,当一个齿进入另一个齿的流体空间时,液体就被机械性地挤排出来。因为液体是不可压缩的,所以液体和齿就不能在同一时间占据同一空间,这样,液体就被排除了。由于齿的不断啮合,这一现象就连续在发生,因而也就在泵的出口提供了一个连续排除量,每转一转,排出的量是一样的。随着驱动轴的不间断地旋转,也就不间断地排出流体。齿轮泵的流量直接与转速有关。

对于粘度或密度在工艺中有变化的流体,这种泵不会受到太多影响。如果有一个阻尼器,比如在排出口侧放一个滤网或一个限制器,泵则会推动流体通过它们。如果这个阻尼器在工作中变化,亦即如果滤网变脏、堵塞了,或限制器的背压升高了,则泵仍将保持恒定的流量,直至达到装置中zui弱的部件的机械极限(通常装有一个扭矩限制器)。

对于一台泵的转速,实际上是有限制的,这主要取决于工艺流体,如果传送的是油类,泵则能以很高的速度转动,但当流体是一种高粘度的聚合物熔体时,这种限制就会大幅度降低。

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.
