法国BUCHER公司制造的内啮合直线共轭齿廓高压齿轮泵是近十几年来国际上出现的先进油泵类型之一。该泵是一种同轴式高、低压两用泵,具有结构简单、紧凑、工作稳定,噪声低,寿命长等优点。本文对该泵的工作原理、设计方案、测试资料进行计算和分析,现介绍如下。总体结构 1.供油系统高压齿轮泵在系统中的联结如图1所示。系统通过阀组能使高、低压泵并联作大流量供油,可实现快速进给,此时压力为140MPa,流量为121L/min;当
France BUCHER company’s internal gear linear conjugate tooth profile high pressure gear pump is more than a decade the international emergence of advanced pump type. The pump is a coaxial high and low pressure dual-use pump, with a simple structure, compact, stable, low noise, long life and other advantages. This paper on the pump working principle, design, test data calculation and analysis are presented below. Overall structure 1. Oil supply system High pressure gear pump in the system as shown in Figure 1. System through the valve can make high and low pressure pumps in parallel for large flow of oil, fast feed can be realized, this time the pressure is 140MPa, the flow rate of 121L / min; when
