Description

三级变量色浆泵及其操作方法 技术领域
本发明属于调色设备领域，尤其是一种三级变量色浆泵及其操作方法。
背景技术
调色对色浆的量有严格的要求，要求泵在注出大量色浆时色浆注出量的误差不能超过一定的百分比，对于在注出微量色浆时色浆注出量的误差同样不能超过一定的百分比。然而目前常见的大量注出色浆的往复泵由于单位行程注出量大，即使泵行程出现少许偏差，也可能导致微量注出色浆时的较大注出偏差，引起颜色异常，不能满足产品需求。所以在调色设备的色浆注出精度控制标准上就呈现出微量注出色浆的精度要求低于大量色浆情况。目前的解决方法主要有同时设置两台调色机，一台是大泵组成的调色机主要负责注出大量色浆，另一台是小泵组成的调色机负责注出微量色浆，这样做虽然可以良好解决控制泵出色浆量，但是设置两台调色机不但多花许多的钱，而且所需空间较大，使用不方便，不符合现代经济集约化生产需求，特别是不适合店面中的使用；另一种解决方法在于在同一个泵中一个大截面缸体的大泵并联用一个小截面缸体的小泵，并排设置一对注出大量和注出微量两个泵出系统，这样做同样存在所占空间较大，结构复杂，成本高的问题。
