双活塞灰浆泵与我国常用的单活塞灰浆泵及挤压泵相比,具有出浆连续均匀、脉动极小的特点。本文试就该种泵的主要零件——驱动凸轮的轮廓设计作一探讨。一、双活塞灰浆泵工作原理双活塞灰浆泵的结构示意图见图1。该泵的两个缸,一个为工作缸,另一个为补偿缸;工作缸活塞由主凸轮驱动进行压浆, Compared with the single-piston mortar pump and the extrusion pump commonly used in China, the double-piston mortar pump has the characteristics of continuous and uniform pulping and minimal pulsation. This article tries to discuss the main part of the pump, the contour design of the driving cam. First, the principle of double-piston mortar pump Double piston mortar pump structure shown in Figure 1. The two cylinders of the pump, one for the working cylinder and the other for the compensation cylinder; the piston of the working cylinder is driven by the main cam for grouting.
