Working Method of 2YV Ejection Oil Solenoid Valve
The oil injection solenoid valve 2YV is used in the steam turbine oil injection test device. Due to the fact that the mechanical overspeed of the steam turbine is composed of springs and flying hammers in its protective action circuit, in order to prevent rusting and jamming of the flying hammers...Read more -
Function of Servo Valve SM4-20(15)57-80/40-10-H607H in Steam Turbine
The function of the electro-hydraulic servo valve SM4-20 (15) 57-80/40-10-H607H is to convert the electrical signals of speed and load into hydraulic signals through the servo valve, push the hydraulic motor spool valve to move, change the opening of the speed control valve, and change the steam ...Read more -
Function of Solenoid Valve GS020600V for Steam Turbine DEH
The OPC valve GS020600V function in the steam turbine generator is to quickly close the speed control valve, extraction control valve, and various extraction check valves without interrupting the turbine. There are three types of signals that can trigger the overspeed protection signal action and...Read more -
How Does OPC Solenoid Valve Z6206060 Work?
Under normal shutdown conditions, the sliding parameters of the boiler exhaust the raw coal in the coal bunker, and the load of the steam turbine generator unit cannot continue to decrease as the boiler parameters decrease to a certain extent. Generally, when the steam turbine casing wall tempera...Read more -
Introducing Hydrogen Sealing Oil Pump HSNH80Q-46NZ
The oil pump HSNH80Q-46NZ is used for the sealing oil system of the generator. When the oil pump is started, the exhaust valve installed on the outlet side of the system must be opened until the air on the suction side of the pump is completely discharged: if liquid emerges from it, the valve can...Read more -
What is the AST Solenoid Valve 0508.919T0301.AW027?
The AST solenoid valve 0508.919T0301.AW027 is controlled by the ETS system of steam turbine, and the four solenoid valves are arranged in series and parallel to form the AST component. During normal operation, these four AST solenoid valves are electrically closed, sealing the oil drain channel o...Read more -
Setting Gas Pressure of Hydraulic Accumulator NXQA.25/31.5
The accumulator NXQA.25/31.5 is a pressure vessel that is an important tool for maintaining system pressure and stability in hydraulic systems.
