　　MG200系列MG209YD0GT批发中心Fluid不锈钢齿轮泵Fluid叶片泵

　　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。

　　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.
