Oil Return Filter ZNGL02010201 for Medium-Speed Mills: Preventing Oil Bypass During Installation
The ZNGL02010201 oil return filter is installed on the return pipeline of the hydraulic oil station serving medium-speed mills. Its job is straightforward: remove wear particles and other contaminants before the oil flows back to the tank. These contaminants mainly come from pumps, valves, cylind...Read more -
HXW-R Thermal Expansion Monitor: Managing Steam Turbine Casing Growth
Big steam turbines go through massive temperature changes when you start them up or shut them down. When hot steam pours inside, the heavy steel shell expands quite a bit. This movement has to happen smoothly along the tracks on the floor. The HXW-R Thermal Expansion Monitor is the tool that watc...Read more -
WZPK2-336S Armored RTD Temperature Sensor Deviation Logic and Replacement Timing
The WZPK2-336S is a dual-element armored Pt100 temperature sensor built for continuous bearing temperature monitoring on steam turbines, feed pumps, fans, and similar rotating machinery. Both Pt100 elements share the same stainless steel armored sheath with magnesium oxide fill, and both are inte...Read more -
WZP2-3.2/30/1.5/7 Platinum Thermal Resistance: Turbine Bearing Metal Temperature Monitoring and Spring-Contact Installation
The WZP2-3.2/30/1.5/7 is a face-contact platinum thermal resistance designed specifically for measuring bearing pad metal temperature on steam turbines. It sits against the back of the bearing pad through a spring-loaded mechanism, and that direct contact is what makes it measure metal temperatur...Read more -
SZ-6A Magneto-Electric Vibration Sensor: Bearing Vibration Monitoring and Alarm Source Diagnosis
The SZ-6A is an inertial magneto-electric velocity sensor used to measure absolute bearing housing vibration on steam turbines, feed pumps, induced draft fans, and similar rotating machinery. No external power supply is required — the sensor generates its own output voltage through electromagneti...Read more -
DJM1615-87 Boiler Water Level Electrode: Why Signal Flicker Happens and How to Isolate the Real Fault Source
The DJM1615-87 is an external-thread electrode rod for electric contact water level gauges installed on boiler drums, high and low pressure heaters, and deaerators. It forms the core sensing element of the level measurement chain — the component that determines, at each discrete measurement point...Read more -
ME5.530.172 Electric Actuator Display Card: Function, Black Screen Diagnosis, and Voltage-Based Fault Isolation
The ME5.530.172 is the local display and control module fitted to motor-operated valve (MOV) electric actuators. It gives operators direct access to valve position feedback, operating parameters, and fault status at the actuator itself — independent of what the DCS is showing in the control room....Read more -
XDH-20C High-Energy Igniter DCS Integration and On-Site Fault Diagnosis
The XDH-20C is a capacitor-discharge high-energy igniter designed for boiler burner ignition systems. It converts a 220V AC supply into a 3000V DC charge stored in a capacitor bank, then releases that energy in a controlled pulse through a semiconductor ignition nozzle at the oil gun tip. When th...Read more -
WRNK2-321 Armored Thermocouple Compression Fitting Installation and Bending Hazards
The WRNK2-321 is a dual-element K-type armored thermocouple with an adjustable compression fitting for threaded process connections. Both thermocouple elements share one sheath but operate independently — giving you a backup reading from the same point without pulling a second assembly through th...Read more -
KQF1500 Generator Gas Leakage Transmitter: Alarm Validation and Multi-Data Diagnosis
The KQF1500 is an online gas leakage detection transmitter for hydrogen-cooled generators, built around thermal conductivity sensing to continuously monitor hydrogen concentration inside the generator casing. It sends a 4–20 mA signal to the DCS and activates relay alarm contacts when concentrati...Read more -
ZKZ-3T Speed Monitor: Creep Detection, and False Alarm Prevention for Hydro Turbine Units
The ZKZ-3T is a multi-purpose speed monitor that combines the functions of a frequency meter, tachometer, speed relay, and speed test instrument in a single panel-mounted device. It is designed for continuous speed monitoring of hydro turbine generator units, providing both digital display and sw...Read more -
Piston Main Oil Pump PVH098R01AD30A250000001001AE010A Early Leak Diagnosis
The PVH098R01AD30A250000001001AE010A is a pressure-compensated variable displacement piston pump used as the main oil pump in steam turbine EH oil systems. It converts motor shaft power into high-pressure fire-resistant oil supply for the turbine’s governing and protection circuits — and un...Read more
