16-Channel Relay Module 3500/33-01-00: Three Steps to Pinpoint the Problem from DCS Alarm
In the turbine monitoring system, the 3500/33-01-00 Relay Module acts as the “signal executor”. When the DCS (Distributed Control System) sends a command—like “Open Valve” or “Start Pump”—the module is responsible for transmitting the signal to the field device...Read more -
Rotor Eccentricity Sensor PR6423/002-030: Identifying EMI and Inspection Priorities
Steam turbine rotor eccentricity monitoring depends entirely on the PR6423/002-030 eddy current sensor. It captures the rotor’s eccentricity value in real time, issuing an alarm if the value exceeds tolerance to prevent shaft rubbing and bearing damage. However, power plant environments are...Read more -
Shaft Vibration Preamplifier TM301-A02-B01-C00-D00-E00-F00-G00 in High-Temperature and High-Humidity Environments
Accurate steam turbine shaft vibration measurement relies heavily on the eddy current proximity probe preamplifier TM301-A02-B01-C00-D00-E00-F00-G00. It acts as the “signal relay station,” amplifying and processing the shaft vibration signal collected by the probe before transmitting ...Read more -
Turbine MSV Position Sensor TD-1-800: Yields Comprehensive Benefits in Unit Safety and Efficiency
The high-pressure main steam valve (MSV) in a steam turbine is the “master gate” controlling the flow of boiler steam into the turbine. The precise degree to which this gate opens or closes relies entirely on the feedback signal from the LVDT linear position sensor. An accurate signal...Read more -
RJ-17.5-950 Bolt Heater + Control Cabinet: High-Efficiency and Safe Heating in Power Plants
In power plants, numerous large bolts are found on turbines and boilers. Dismantling or installing these bolts requires preheating—thermal expansion and contraction loosen the bolts, making them easy to turn. However, the heating process is complex: bolts of different materials and sizes require ...Read more -
AST Solenoid Valve Seat JZPK-003A: Design Logic for Anti-Erosion and Durable Sealing under High Pressure
The AST fire-resistant fluid solenoid valve is the “critical switch” of the turbine emergency trip system, and the valve seat JZPK-003A is the core contact surface of this switch. The fire-resistant fluid pressure in the AST system is high. Long-term, high-velocity fluid scouring aga...Read more -
Collaborative Roles of F3DG5S2-062A-220DC-50-DFZKV/B8 Isolation Valve, AST, and OPC Solenoid Valves in Emergency Trip System
Steam turbines operate at extremely high speeds. If a problem occurs and the unit fails to trip promptly, the consequences can range from minor bearing damage to catastrophic machine write-off. The Emergency Trip System (ETS) is the “life-saving” core of the turbine protection. Withi...Read more -
Turbine Overspeed Protection Solenoid Valve SV4-10-C-0-00: How Threaded Cartridge Design Outperforms Traditional Connections
Turbine overspeed is a critical concern in power generation. Once the rotational speed exceeds the upper limit, the consequences range from minor blade damage to catastrophic machine failure. Within the overspeed protection system, the solenoid valve acts as the “key executor.” The S...Read more -
Sealing Oil Main Pump HSN280-43NZ: Tips for Non-Disruptive Switching Between Main and Standby Pumps
The core task of a generator seal oil station is to supply oil at a stable pressure to the seal pads. This oil pressure seals the hydrogen gas inside the generator. Hydrogen leaks can compromise unit safety, while unstable oil pressure can damage the seal pads. The HSN280-43NZ main oil pump is a ...Read more -
Eddy Current Integrated Transmitter CWY-DO-813601-01-03-05-02: Cost-Effective for Multi-Point Vibration Monitoring
Auxiliary equipment such as fans and pumps in power plants, though not “core assets” like steam turbines or boilers, have vibration conditions that directly affect the stability of the entire unit. Excessive vibration in fans may cause blade breakage, while excessive vibration in pump...Read more -
Advantages of heat-shrouded thermocouple WRNR3-18 in temperature measurement of high-temperature pipelines in power plants
High-temperature pipelines in power plants, such as main steam lines and reheat steam lines, are the “arteries” of unit operation. Temperature monitoring of these pipelines is directly related to unit safety—excessive temperatures or large fluctuations can cause equipment failure. The...Read more -
Precautions For Overhauling and Replacing the DZK430 ESP Signal Sampling Module
In thermal power plants, the electrostatic precipitator (ESP) is a critical device for controlling dust emissions, and the DZK430 signal sampling module serves as the ESP’s “signal hub.” It collects key signals such as dust concentration, plate current, and voltage within the ES...Read more
