rexroth计量泵有的叫定量泵、比例泵、可控制流量泵等。根据预先选定的亮或时间间隔来供给或抽出一定物料的泵，称为计量泵。计量泵是带有行程或往复次数调节的往复式容积泵。计量泵一般可分为柱塞计量泵和隔膜计量泵的两大类。
计量泵应用与化工、石油、制药、采矿、水电、原子能、造纸、水泥及食品等工业部门中，是一类重要的特殊泵。

、性价比高，普遍适用于，压力要求不高的水处理行业
2、采用偏心机构．整体上*无泄露，可安置于药槽或管道上。
3、铸铝壳体，散热性能高，整体重量轻，适用各种酸碱药液，无害无味。
4、接触介质泵头为PVC、可选PTFE、及不锈钢材质。
5、在泵运行或停止时也可任意调节流量也可定量输出。
6、隔膜计量泵为多层复合结构压制而成，
靠前层超韧性Teflon耐酸薄膜，
第二层EPDM弹性橡胶，
第三层厚度3.mm SUS304支撑铁芯，
第四层采用强化尼龙纤维补强，
第五采用EPDM弹性橡胶*包履，可有效提升隔膜使用寿命。特点:
各种流量的计量精度重复性高
通过带内装测量刻度的手轮进行手动调节流量,调节准确,运行平稳
工作压力可到25Mpa
进口压力低,可输送高粘度液体
通过特殊的相匹材料和特殊密封的使用,泵零件与泵输送的材料(多羟基化合物、异氰酸酯)相容。
rexroth计量泵工作原理 :
高压计量泵的作用是将机械能转变为液压能。当电动机带动泵的主轴旋转时,通过连杆柱塞带动缸体旋转,由于缸体轴线与主轴轴线成一夹角,柱塞地缸体内作往复运动,此时缸体内的柱塞孔发生容积变化。当容积由小变大时,介质从泵的吸入口吸入,经配流盘的低压窗口进入柱塞孔、当容积由大变小时,介质经配流盘的高压窗口从泵的排出口排出。这样主轴旋转一周,每个柱塞孔完成一使用条件:
1.油温:HVK系列计量泵的正常工作温度一般在-20℃-70℃,高不超过80℃。当温度低于10℃时,应采取加热措施。
2.粘度:工作介质使用粘度范围应在1000-4000Mpa·s/25℃。对HVK系列计量泵使用的高粘度介质、应加温稀释至此粘度范围,并在工作过程中,在泵的轴封盖上两螺孔处注入二辛酯,使轴封能正常工作。
3.滤油精度:佳滤油精度为10-20um,低不超过30um。
4.泵的常用工作压力和转速不应超过额定值,瞬时不超过高值。高值一般连续使用不超过1分钟,且每班累计不超过10%的工作时间。
5.壳体内腔泄漏油允许压力,不超过0.2Mpa。
