在压力容器、高压设备的耐压试验机和压力机械上,压力伺服是比较常用的一种电液伺服。它与定位伺服不同的是通过压力进行控制,但基本原理是相同的。一、压力伺服的种类压力伺服采用测压仪(压力转换器)做反馈检测器,其基本类型有三种: 1.压力控制伺服阀的使用方法定位伺服采用的伺服阀是流量控制伺服阀,而压力伺服上采用的伺服阀是压力控制伺服阀,它的输入电流是与负载压力成正比的。图1表示采用压力控制伺服阀的压力
In pressure vessels, high-pressure equipment, pressure testing machines and pressure machinery, the pressure servo is more commonly used as a kind of electro-hydraulic servo. It is different from the positioning servo pressure control, but the basic principle is the same. First, the type of pressure servo Pressure servo pressure transmitter (pressure transducer) to do the feedback detector, there are three basic types: 1. Pressure control servo valve using the servo positioning servo valve is the flow control servo valve, and The servo valve used on the pressure servo is a pressure-controlled servo valve whose input current is proportional to the load pressure. Figure 1 shows the pressure control servo valve pressure
