Fluid-o-Tech齿轮泵工作时,主动轮随电动机一起旋转并带动从动轮跟着旋转。当吸入室一侧的啮合齿逐渐分开时,吸入室容积增大,压力降低,便将吸人管中的液体吸入泵内;吸入液体分两路在齿槽内被齿轮推送到排出室。液体进入排出室后,由于两个齿轮的轮齿不断啮合,使液体受挤压而从排出室进入排出管中。主动齿轮和从动齿轮不停地旋转,泵就能连续不断地吸入和排出液体。
泵体上装有安全阀,当排出压力超过规定压力时,输送液体可以自动顶开安全阀,使高压液体返回吸入管。
内啮合齿轮泵,它由一对相互啮合的内齿轮及它们中间的月牙形件、泵壳等构成。月牙形件的作用是将吸入室和排出室隔开。当主动齿轮旋转时,在齿轮脱开啮合的地方形成局部真空,液体被吸入泵内充满吸入室各齿间,然后沿月牙形件的内外两侧分两路进入排出室。在轮齿进入啮合的地方,存在于齿间的液体被挤压而送进排出管。
齿轮泵除具有自吸能力、流量与排出压力无关等特点外,泵壳上无吸入阀和排出阀,具有结构简单,流量均匀、工作可靠等特性,但效率低、噪音和振动大、易磨损,主要用来输送无腐蚀性、无固体颗粒并且具有润滑能力的各种油类,温度一般不超过70 ℃,例如润滑油、食用植物油等。一般流量范围为0.045~30ms/h,压力范围为0.7—20MPa,工作转速为1200—4000r/min。
Fluid-o-Tech齿轮泵结构特点
(1)结构简单,价格便宜;
(2)工作要求低,应用广泛;
(3)端盖和齿轮的各个齿间槽组成了许多固定的密封工作腔,只能用作定量泵。
齿轮采用国际九十年代先进水平的新技术--双圆弧正弦曲线齿型圆弧。它与渐开线齿轮相比,突出的优点是齿轮啮合过程中齿廓面没有相对滑动,所以齿面无磨损、运转平衡、无困液现象,噪声低、寿命长、效率高。该泵摆脱传统设计的束缚,使得齿轮泵在设计、生产和使用上进入了一个新的领域。
泵设有差压式安全阀作为超载保护,安全阀全回流压力为泵额定排出压力1.5倍。也可在允许排出压力范围内根据实际需要另行调整。但是此安全阀不能作减压阀长期工作,减压阀在需要时可另行安装。
该泵轴端密封设计为两种形式,一种是机械密封,另一种是填料密封,可根据具体使用情况和用户要求确定。
齿轮泵泵的分类
就核心组成部件齿轮而言,主要由公法线齿轮泵和圆弧齿轮泵。公法线齿轮泵输送含杂质的介质比圆弧齿轮泵要耐用,而圆弧齿轮泵结构特殊,输送干净的介质,噪音低,寿命长,各有各的优点。

Disassembly Instructions Provide a cleansurface for work area. Separate the pumphead from the magnet cap. Remove the 3screws and disassemble front housing, driven gear , central housing and dowelpins . If the pump is equipped with by-pass, make sure not to damage thesealing poppet . Remove the poppet assembly from the adjusting screw (fig. 5),remove the by-pass nut, the adjusting screw turning counter-clockwise, theby-pass washer and the by pass seal fromthe cap. Remove the screws which securethe magnet cup and the mounting plateto the rear housing and disassemble. Remove and discard all the bushings from the rear housing and the front housing with the bushing extractor tool P/N 60211(fig.1). Remove seal and flat seals fromthe rear housing and from the front housing and discard them. If wear on fronthousing, rear housing or center housing is excessive, rebuilding the pump mynot be advisable.
Re-Assembly Instructions Clean carefullyall parts before re-assembling. Any foreign body material clinging to magnetmust be removed.
Note Bushings - Bushings on both sides ofgears must be recessed 0.5 mm from the face of the rear housing and fronthousing (fig. 2) BushingsInstallation - Press 6 new bushings into the rear housing andfront housing as shown in figure 2using P/N 60212 installation tool. Once in place, the bushings need to bereamed with P/N 60210 reamer tool (fig. 3). Seals - Apply a thin coat ofsilicone grease on the central housing surfaces and place the flat seals on each side of it insert the driving gear into the rear housing and then insert theshaft of the driving gear in the driven magnet using the spacer P/N 60213 (fig.4). Insert 2 dowel pins in the body.Slip carefully central housing ontodowel pins against body face, verifying the proper, alignment of the screwholes. Install the driven gear (Theside of gear assembly with longer shaft extension goes into the rear housing).If pump is equipped with by-pass, install the by-pass
seal , then by-pass nut andtighten to prevent by-pass seal rotation. Then tap the by-pass seal with theP/N 60214 tool (fig. 6). Disassemble the by-pass nut and install by-pass washerand turn clockwise the adjusting screw before installing again the by-pass nut tightening. Align the capbushing holes with gear shafts, and dowel pins with cap dowel pin holes and assemble.Make sure that the poppet assy goes fully into poppet holes and seat (fig. 5).Install 3 screws in cap and tighten alternately as tight aspossible. Turn driven magnet with fingers to check for any binding during therotation: the magnet should turn freely. Install magnet cup and mounting plate with 3 screws and turn alternately until tight.Assemble the driving magnet to the motor (see fig. 7) and the pumphead to themotor.
