玉米生物秸秆燃料液压机设计
摘要
玉米生物秸秆燃料是由玉米秸秆通过压力机压制成一定密实度的燃料块,而具体的压块方式采取液压式驱动。四柱液压机由主机及控制机构两大部分组成。液压机主机部分包括液压缸、横梁、立柱及充液装置等。动力机构由油箱、高压泵、控制系统、电动机、压力阀、方向阀等组成。液压机采用PLC 控制系统,通过泵和油缸及各种液压阀实现能量的转换,调节和输送,完成各种工艺动作的循环。该系列液压机具有独立的动力机构和电气系统,并采用按钮集中控制,可实现手动和自动两种操作方式。该液压机结构紧凑,动作灵敏可靠,速度快,能耗小,噪音低,压力和行程可在规定的范围内任意调节,操作简单。在本设计中,通过查阅大量文献资料,设计了液压缸的尺寸,拟订了液压原理图。按压力和流量的大小选择了液压泵,电动机,控制阀,过滤器等液压元件和辅助元件。

Abstract
The four-pillars hydraulic press is divided into two parts, host machine and control mechanism. Hydraulic press host machine is make up of hydraulic cylinder,
beam, upright, prefill valve and so on. Dynamic mechanism is make up of tank, high
pressure pump, control systems ,electromoto, pressure valve, direction valve and so
on. Hydraulic press control systems adopt will e true energy conversion,
regulate and transport, all kinds of technical motions cycle, through control pump, hydraulic cylinder and all kinds of hydraulic valve. The series hydraulic machine is an independent body and the electrical power system, and centralized control buttons
used, achieve both manual and automatic operation mode. This hydraulic system framework pact, movement keen reliable, the speed is quick, the energy consumption is small, the noise is low, the pressure and the traveling schedule may adjust willfully in the stipulation scope, the operation is simple. In this design, through the consult massive literature material, has designed the hydraulic cylinder size, has drafted the hydraulic pressure schematic diagram. According to the pressure and the current capacity size choose the hydraulic pump, the electric motor, the control valve, hydraulic pressure parts, the auxiliary part and filter.
