Research on pipeline pressure shock in valve control hydraulic positioning system
A new control approach is proposed for multimachine power systems during transient crises. The variable structure control theory is applied to design the valve control law.
The check is in the series of coil and four-way reversing valve control relay contact resistance increases, the bad, the contacts the voltage reduced.
exhaust by-pass valve control wire switch
Key warder: valve control lead storage battery; charge method; balanced; Circling life.
The result shows that superfluous force is less in double valve parallel control system than that in single valve control system, and the precision of dynamic loading is increased.
Rubber lined diaphragm surface of the body cavity lined or covered with a choice of a variety of rubber, dedicated to the diaphragm valve control non-corrosive or corrosive media.
Hydraulic systems use cartridge valve integrated control system, integrated cartridge valve control system has good sealing, flow capacity, small pressure loss characteristics etc.
It is also discussed that the limitation method used in pump control system can be used in the valve control system.
self-rectifying wet-type solenoid for valve control
The former is the process of inhalation and discharged at the same pump cylinder alternately conducted by the inhalation valve and exhaust valve control;
The utility model relates to an electric ceramic water mixing valve which belongs to fluid valve control technical field.
By regarding testing mechanics behaviors of frozen soil frost heave as the research background, a hydraulic force control system was designed on the basis of valve control asymmetric cylinder.
Expound pump station operation adopting the rotational speed control the law more advantage than the valve control the law in energy-conservation.
valve control motor
A throttle valve control device is composed of a stator core with a solenoid and a rotor carrying a throttle valve.
