我院运用教研室胡南强、梁汉业等同志最近研制出YSK—1型孔板式拖拉机液压系统试验仪样机。这种仪器可用来对各种国产拖拉机液压系统(压力不超过175公斤力/厘米~2,流量不超过76升/分)的技术状态进行不拆卸检查与试验,包括对整个液压系统及其主要元件的内漏程度进行测定,和检查、调整系统的各个压力控制阀门,还可用来分析、查找故障。试验仪主要由节流加载装置、孔板流量计和温度计三部分组成。流量计部份采用了孔板节流、普通压力表显示和可变节流阀对回油阻力进行补偿调整的方案,因而测量精度较高、
Our hospital using research room Hu Nanqiang, Liang Hanye and other comrades recently developed YSK-1-type orifice plate tractor hydraulic system tester prototype. This instrument can be used for a variety of domestic tractor hydraulic system (pressure not exceeding 175 kgf / cm ~ 2, the flow does not exceed 76 l / min) technical state without dismantling inspection and testing, including the entire hydraulic system and its main Components of the degree of leakage within the determination, and check, adjust the system pressure control valve, but also can be used to analyze, find fault. Tester consists of throttling loading device, orifice flowmeter and thermometer composed of three parts. Flowmeter part of the orifice throttling, ordinary pressure gauge display and variable throttle valve on the oil resistance compensation program to adjust, so the measurement accuracy is high,
