LSJD200-1A/LSJD-2A
Main functions and features:
1. The oil cup adopts a three-electrode structure that complies with the national standard GB/T5654-2007, with an electrode spacing of 2 mm. This design eliminates the influence of stray capacitance and leakage on the dielectric loss measurement results. The oil cup is equipped with an electromagnetic oil-discharge switch, allowing the sample oil in the cup to be drained without disassembling the cup itself. Additionally, the sample oil can be used to flush the oil cup.
2. The instrument employs medium-frequency induction heating and a PID temperature-control algorithm. This heating method offers advantages such as non-contact between the oil cup and the heating element, uniform heating, fast heating speed, and convenient control, ensuring that the temperature is strictly maintained within the preset tolerance range.
3. The internal standard capacitor is an SF6-gas-filled three-electrode type capacitor. The dielectric loss and capacitance of this capacitor are unaffected by ambient temperature, humidity, and other environmental factors, ensuring that the instrument’s accuracy remains guaranteed even after prolonged use.
4. The AC-DC-AC conversion method is used for the交流 test power supply, effectively eliminating the impact of fluctuations in mains voltage and frequency on the accuracy of dielectric loss measurements. Even when powered by a generator, this instrument can operate correctly.
5. Comprehensive protection features: When overvoltage, overcurrent, or high-voltage short circuits occur, the instrument can quickly cut off the high voltage and issue a warning message. It also issues a warning message if the temperature sensor fails or is not connected.
6. A temperature-limiting relay is installed inside the medium-frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay releases, and the heating stops.
7. The color touch LCD screen is easy to operate via a touch-sensitive LCD display, with Chinese character menu prompts.
8. Equipped with a real-time clock, the test date and time can be saved, displayed, and printed along with the test results.
9. Empty electrode cup calibration function. Measures the capacitance and dielectric loss factor of the empty electrode cup to assess its cleaning and assembly condition. Calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
10. The upgraded version is compact and lightweight.

VRP Series Varnish Removal Oil Purifier
Application
Used in gas and steam turbine, compressor, to remove dissolved and suspended soft pollutants in oil products, sludge and other harmful substances. Avoid turbine failures and expensive oil changes due to paint film problems. When the film is formed, the loss of production is very high. The initial formation of the film is known as a soft pollutant, caused by hot spots in the system, such as bearings, pumps, and high flow on-line filtration. Recent studies have found that the existence of soft pollutants can be divided into dissolved state and suspended state, by removing these soft oxides can avoid the production of paint film. Once the film forms, it will clog valves, filters and other small links, and the life of the oil will be significantly reduced.
The formation of cleaning film will cause the following adverse consequences: valve adhesion, loss of control, resulting in unit failure or startup failure; Filter plugging, limiting oil flow, resulting in oil temperature rise and wear increase; Heat exchange failure, oil temperature rise; Sandpaper surface, increase component wear; Forming paint on the bearing, limiting flow, increasing wear and temperature; Frequent oil changes and system flushes. When the soft pollutants are dissolved in the oil, typically when the oil temperature is above 40℃, they cannot be removed by ordinary mechanical filtration or electrostatic filtration, and these soft pollutants show natural magnetism. For polar absorption, the cooler metal surface "cold spot", i.e. the valve and cooler. When the temperature of the oil is lowered, the thermal stability of the soft pollutants is less than that of the oil, so they are more likely to bake hard on hot surfaces, such as axial shafts.
VRP paint film cleaner. It achieves revolutionary and efficient removal of soft pollutants (dissolved and suspended) from oil products, including gas and steam turbines and compressors under high temperature operation. The warm oil is pumped from the lowest point at the bottom of the tank to the VRP paint film purifier by the equipment's own transfer pump. After cooling treatment (using the thermal stability of the paint film is worse than that of oil), the paint film, particulate matter and moisture are removed by the filter element with wood fiber as the raw material (no need to use ion-exchange resin filter material, greatly saving the cost of use).
Features:
● Increase system reliability and stability. ● No more shutdowns and startup failures caused by paint film.
● No longer need to clean the tank and system flushing. ● Increase jacking oil pressure, more stable bearing temperature.
● Improve the life of oil products, blood additives and system components, such as bearings, valves, seals, etc.
● Great savings can be achieved by avoiding turbine failure and extending the life of oil products. Features:
