As one of the most vitality offset of hydro-liquid drive and control field , Electro-hydraulic proportion controls technique fills up a blank between traditional on-off hydraulic pressure control technique and servo-control technique.
As one of the most vitality offset of hydro-liquid drive and control field, Electricity-Hydraulic proportion controls technique fills up a blank between tradition on-off hydraulic pressure control technique and servo-control technique.
By using hydraulic pressure control theories as foundation, and electrorheological fluid based on Bingham mode under an electric field as running medium, the control equation of the Electrorheological Valve System was obtained.
Along with fathering and dredging of sea-route, tonnage of private freight barge on some area of Tai Lake drainage area is becoming bigger, so the operating system of navigating and capstan machine changes from tradition machine type or manual operation to hydraulic pressure control type ,thus it not only increases logistics speed, enhances navigation security, lightens laboring intensity, but also acquires evidence economy benefit and society benefit.
The paper analyses the cleaning process of the capacitor,designs the automatic control system based on the PLC control technology and the fluid control technology,and solves the technology matters. The equipment can do actions such as the elevation and subsidence,the indexing of five operation positions,and the flutter,and it operates conveniently with good performance.
The applicaion of difforenttal pressure sensor makes load -sensing hydraulic controlling realized,which enables excavator get the optimum flow,raise working efficiency and complex-operation ability,and attain the aim of economizing-energy,and promote the technique advancement.
This research provides an effective method for lifting forces of hydraulic controlling flap gate and has a significant value to the design of hydraulic operation lifting system and the application of hydraulic controlling flap gate.
Hydraulic synchronized continuous slippage technique, which integrates mechanical, electrical and hydraulic control, is introduced in this paper for the practical requirements of some construction projects.
For hydraulic control systems, an optimal PID controller with inverse of dead zone is introduced to overcome the dead zone and is designed to satisfy desired time-domain performance requirements.
It is shown that the coupled model supports unforced modes of interdecadal oscillation resulting from a form of hydraulic control which regulates the total fluid volume in the oceanic active layer.
The management of the hydraulic control structures has decreased low-frequency, high-stage flows, which are the dominant geomorphic force in bedrock channel systems.
The ecological role of seawater intrusion in Laguna de Bay is assessed due to the operation of the Napindan Hydraulic Control Structure (NHCS).
Techniques using Coanda effect have been applied to the fluid control devices.
Fluid control mechanisms after exercise dehydration
Successful fluid control was defined as more fluid output than input over the course of PD/CHDF.
Successful fluid control was achieved in 17 of 26 (65%) CHDF patients and in 5 of 14 (36%) PD patients (P>amp;lt;0.01, chi-squared).
Clinical studies using icodextrin have shown better fluid control, especially in high transporters, reduced carbohydrate load and fewer patients with ultrafiltration failure compared with those treated with conventional dialysis solutions.
