Disassembly Instructions Provide a clean surface for work area. Separate the pumphead from the magnet cap. Remove the 3 screws and disassemble front housing, driven gear , central housing and dowel pins . If the pump is equipped with by-pass, make sure not to damage the sealing poppet . Remove the poppet assembly from the adjusting screw (fig. 5), remove the by-pass nut, the adjusting screw turning counter-clockwise, the by-pass washer and the by pass seal from the cap. Remove the screws which secure the magnet cup and the mounting plate to 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 from the rear housing and from the front housing and discard them. If wear on front housing, rear housing or center housing is excessive, rebuilding the pump my not be advisable.
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,最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。
