High Temperature Rubber Bladder of A-10/31.5-L-EH Accumulator
The working conditions of steam turbines in thermal power plants is high temperature and high pressure, in which ordinary hydraulic oil is easy to burn. However, the self-ignition point of phosphate ester fire-resistant oil is relatively high, even if it falls on the surface of hot steam pipeline...Read more -
How to Confirm the Charging Pressure of Accumulator NXQ-F16/20-H-HT
The main functions of the hydraulic accumulator NXQ-F16/20-H-HT are shock buffering, pulsation damping, and energy storage. The charging pressure of accumulators with different functions also varies. Generally, inflation can be carried out according to the requirements of the accumulator user man...Read more -
Why Using Pressure Relief Valve YSF16-55*130KKJ In Transformer Oil Tank?
The pressure relief valve YSF16-55*130KKJ is suitable for oil immersed power transformers, power capacitors, and cut and tap switches to protect the oil tank. The pressure relief valve of the power transformer is located above the transformer. If the transformer oil seeps out from here, it indica...Read more -
How to Replace Bladder Accumulator Repair Seal Kit NXQ-L40/31.5H
The NXQ type accumulator seal kit has the characteristics of high pressure resistance, high speed, and good sealing. Yoyik recommends it for the NXQ-L40/31.5H accumulator. At the connection between the accumulator and the hydraulic system, as the system pressure changes, the sealing ring is often...Read more -
Structure of HSNH440Q2-46NZ Generator Sealing Oil Pump
HSNH440Q2-46NZ screw pump is a hydraulic oil pump used in the sealing oil system of the generator. When the spiral surface active screw composed of a special profile rotates, its dynamic sealing chamber will suck in the liquid from the suction inlet and continuously and pulsatively transport it t...Read more -
Introducing DFB100-80-230 Stator Cooling Water Pump
The stator cooling water pump DFB100-80-230 is an important supporting equipment that provides stable and suitable cooling water to the generator stator to ensure that the stator will not be damaged or malfunctioned due to overheating during operation. Once there is a problem with this pump, it i...Read more -
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
