  • Boiler Tube sliding block

    Boiler Tube sliding block

    Boiler Tube sliding block, also known as Sliding pair, is composed of two components, which can only move in a certain direction. It has the function of keeping the tube platen flat in the platen superheater and preventing the tube from being out of line and dislocated and the formation of coke residue. The sliding pair is generally made of ZG16Cr20Ni14Si2 material.
  • MG00.11.19.01 coal mill Hydraulic reversing valve

    MG00.11.19.01 coal mill Hydraulic reversing valve

    Coal mill loading system is an important part of coal mill, which consists of high pressure oil pump station, oil pipeline, hydraulic reversing valve, loading cylinder, accumulator and other components. Its function is to apply suitable grinding pressure to the grinding roller, and the loading pressure is controlled by the proportional relief valve according to the command signal: the grinding roller is raised and lowered synchronously.
  • Boiler water cooling wall tube of power plant

    Boiler water cooling wall tube of power plant

    The water cooling wall tube is the only heating surface in the evaporation equipment. It is a radiation heat transfer plane composed of continuously arranged tubes. It is close to the furnace wall to form the four walls of the furnace. Some large-capacity boilers arrange part of the water-cooled wall in the middle of the furnace. The two sides absorb the radiant heat of the flue gas respectively, forming the so-called double-sided exposure water wall. The inlet of the water cooling wall pipe is connected by the header, and the outlet can be connected by the header and then connected to the steam drum through the air duct, or it can be directly connected to the steam drum. The inlet and outlet headers of the water wall on each side of the furnace are divided into several, the number of which is determined by the width and depth of the furnace, and each header is connected with the water wall pipes to form a water wall screen.
  • Generator motor electric tool carbon brush

    Generator motor electric tool carbon brush

    A carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery. It is generally made of pure carbon plus a coagulant and acts on the commutator of a DC motor. The application materials of carbon brushes in products mainly include graphite, greased graphite, and metal (including copper, silver) graphite. The appearance of the carbon brush is generally a square, which is stuck on a metal bracket. There is a spring inside to press it on the rotating shaft. When the motor rotates, the electric energy is sent to the coil through the commutator. Because its main component is carbon, it is called carbon. Brush, it is easy to wear. Therefore, regular maintenance and replacement are required, and carbon deposits are cleaned up.
  • ZJ series steam turbine bolt heating rod

    ZJ series steam turbine bolt heating rod

    Dongfang Yoyik (Deyang) Engineering Co., Ltd develops and produces ZJ series AC/DC large bolt electric heaters for Dongfang steam turbine units. The heating element is made of 0Cr27AlMo high-temperature resistance alloy wire, and the protective casing is high-quality 1Cr18Ni9Ti stainless steel tube. It uses crystal magnesium oxide powder as filler and is formed by compression molding to ensure efficient use of the electric heating element. Over the years, the company has been well-known for the use of bolt heater in many power plants.
