方向阀 meaning in Chinese
directioal valve
direction valve
directional valve
Examples
- The respect drive system design : the servo valve commonly used in the closed - loop control system is replaced with the proportion direction valve , and controlled it with the methods of electrohydraulic proportional control . the system adopts the hydraulic circuits that prevent the simulating table letting down because it own weight take place
驱动系统设计方面：用比例方向阀取代了液压闭环控制系统中常用的伺服阀，采用电液比例技术对其进行控制，并在液压油路中采用了防止因仿真转台自重而产生缓慢下滑的液压回路。 - Electro - hydraulic control principle applied in construction machinery is analyzed in this paper ; working principle and application characteristic of electro - hydraulic proportional is lucubrated ; technique and static characteristic of electro - hydraulic proportional decompression value and electro - hydraulic proportional direction value is emphatically analyzed and studied ; electro - hydraulic proportional control mode is setup . the hydraulic circuit which can be not only suit for handle operation but also for remote operation in the same construction machinery , and the hydraulic system design methods is also introduced that the proportion control use d for the steering devices and the working devices of the machine
本文对工程机械上应用的电液控制原理进行了分析；对电液比例阀的工作原理和应用特点进行了深入研究；重点对电液比例减压阀和电液比例方向阀技术特征和静态特性进行分析研究；建立电液比例控制模型；提出了在同一台工程机械上，既能满足遥控又能满足手控的液压回路，以及采用比例量控制行驶和工作装置的液压系统设计方法。 - The control precision of the slider with 2400mm effective stroke can reach 0 . 05mm . the properties of the position control system are not exigent , only the dynamic non - overshooting and the stable - state - precision are considered . the system has given out satisfactory result when used in practical engineering , 0 . 03mm position control precision has been achieved , on account of dead band , the performance of proportional valve is worse than that of servo valve , but some advantages of proportional valve has made it more fit for industrial control
系统方案采用重复性能（反向回差）好的比例方向阀，使有效行程为2400mm的滑块控制精度达到0 . 05mm ，位控系统快速性要求不高，主要考虑系统稳态重复精度，此方案在实际工程中已经取得了满意的效果，位置控制精度达到0 . 03mm ，可以取代同类产品中日本川崎重工的泵控系统。 - In the special fields locking valves , underground mining , water hydraulic systems or beyond that with mining machines , hydraulics , selector valves as well as with aggregates , open cast pit , strip mining , surface mining and / or with hydro and hydraulically is saartech hydraulik gmbh well - known
