Cartridge Mechanical Seal
Mechanical seal is a key component for controlling fluid leakage in rotating equipment. Its function is to establish a reliable seal between the high-speed rotating shaft and the stationary pump casing/equipment casing, preventing the leakage of working medium (liquid, gas or slurry) or the intrusion of external impurities. Under the harsh working conditions of high temperature, high pressure, high speed, and strong corrosion in thermal power plants, the reliability of mechanical seals is directly related to equipment safety and environmental compliance.
Gearbox
In thermal power plants, gearboxes are crucial power transmission and speed control equipment, mainly concentrated in core auxiliary machines such as coal mills, coal feeders, air preheaters, various fans, water pumps, mixers, coal conveying equipment, dust removal and vibration machines that have strict requirements for low-speed and high torque. The following are the key application positions and roles of reducers in the main systems of thermal power plants.
Sealing Element
In thermal power plants, although seals are small, they are the 'micro defense line' that ensures the safe, efficient, and environmentally friendly operation of equipment. They are distributed in harsh environments with high temperature, high pressure, high speed, and strong corrosion. Their core function is to block the leakage path of the medium, prevent energy loss, environmental pollution, or equipment damage.
YCB Series Arc Gear Pump
lt applies to delivering non-corrosive lubricating-oil or equivalent liquid without solid particles and fibres at temperature below 300'C and with the viscosity of 5x10-'. 1.5x10-m’/s(5-1500cSt).lt applies to hydraulic system, too. Reducing the speed, the pump can delivery the liquid that viscosity can be up to 5x10'cSt.
